Definitions
- the present invention relates to a steel of high mechanical strength, high toughness and corrosion resistance, and more particularly to a seamless steel tube of thick wall thickness, with high mechanical strength, high toughness to prevent the progress of cracks both in the base metal and in the area affected by heat and corrosion resistant, called a catenary configuration channeler, to be used as a conductor of high temperature fluids, preferably up to 130 ° C and high pressures, preferably up to 680 atm. and a method of manufacturing it.
- catenary configuration channelers commonly known in the petroleum medium as Steel Catenary Risers, are used. These channelers are located in the upper part of the submarine laying, that is, between the surface of the water and the first point where the laying touches the seabed and they make up only part of the complete driving system.
- This channeling system is essentially composed of conduit pipes, which have the function of conducting fluids from the seabed to the sea surface. These pipes are currently made of steel, and are generally connected to each other by welding.
- channelers There are several possible configurations for the channelers, one of them is the non-symmetric catenary configuration channeler. This name is due to the fact that the curve that describes the driving system that is fixed at its two ends (seabed and sea surface) is a catenary curve.
- a channeling system like the one described above is exposed to the wave movements produced by waves and sea currents. Fatigue resistance is therefore a very important property in this type of pipes, this phenomenon becoming critical in the welded joint between tube and tube. For this reason, restricted dimensional tolerances, uniform mechanical resistance properties and high tenacity for the prevention of cracks in both the base metal and in the area affected by heat are the main characteristics of this type of pipe.
- the fluid that circulates through the channeler can contain H2S, so it is also necessary for the product to have high corrosion resistance
- the medium in which the tube must work sometimes means maintaining its operation at low temperatures.
- Many of the deposits are located at latitudes that involve low ambient temperatures, so the tube must maintain its mechanical properties even at those temperatures.
- a common practice used to increase the strength of a steel product is to add alloying elements such as C and Mn, perform a tempering and tempering heat treatment and add elements that generate precipitation hardening such as Nb and V.
- alloying elements such as C and Mn
- perform a tempering and tempering heat treatment and add elements that generate precipitation hardening such as Nb and V.
- Nb and V precipitation hardening
- Channels are pipes that, like conduction pipes, carry a liquid, a gas or both.
- Said pipe is manufactured under norms, standards, specifications or codes that govern the manufacture of conduction pipe in most cases. Additionally they are characterized and differentiated from the standard conduit pipe in terms of chemical composition range, restricted range of mechanical properties (creep, strength and their ratio), low hardness, high toughness, dimensional tolerances restricted in internal diameter and criteria Severe inspection.
- Mn is an element that increases hardenability in steel, promoting the formation of martensite, as well as the promotion of the MA constituent, which is detrimental to tenacity.
- the Mn promotes a high central segregation in the steel bar from which the tube is laminated, even more in the presence of P.
- the Mn is the second largest element with a large segregation index, it favors the formation of MnS inclusions and even when the steel is treated to Ca, due to the problem of central segregation in Mn contents above 1.35%, these inclusions are not eliminated.
- the main objective of this invention is to provide a chemical composition of the steel used for the manufacture of a seamless tube and a manufacturing process that allows to obtain a product with high mechanical resistance at room temperature and up to 130 ° C, high toughness, low hardness , good corrosion resistance in media containing H2S and high toughness values in terms of resistance to cracks in the BEAM evaluated by the CTOD test (by its denomination in English "Crack Tip
- Still another objective is to make possible a product that has an adequate balance of the qualities indicated above and that can meet the requirements that a channeler must have to conduct fluids at high pressures, that is, greater than 680 atm.
- Still another objective is to make possible a product that has good resistance values at high temperatures.
- a fourth objective is to provide a heat treatment to submit the seamless steel tube, which allows to obtain the mechanical properties and corrosion resistance.
- the present invention consists of one of its slopes in a steel of high mechanical resistance at room temperature and up to 130 ° C, high toughness and low hardness which also has good corrosion resistance and high resistance to cracking in MAKE it once welded the tube to be used in the manufacture of steel tubes that make up a system underwater channeler
- the invention consists of a method for manufacturing this type of tube.
- the alloy is first manufactured with the desired chemical composition.
- This steel must contain in percentage by weight the following elements in the amounts described: C 0.06 to 0.13; Mn 1, 00 to 1, 30; Yes 0.35 max .; P 0.015 x .; S 0.003 max. ; Mo 0, 10 to 0, 20; Cr 0.10 to 0.30; V 0.050 to 0.10;
- the steel obtained is solidified in the form of billets or ingots which are then drilled and rolled to give them tubular shape.
- the mother tube thus obtained is then adjusted to its final dimensions.
- the wall thickness of the tubes should be set in a range of> 30 mm.
- the steel tube is subjected to a tempering and tempering heat treatment to confer its microstructure and final properties.
- Figure 1 shows the creep resistance measured in Ksi and the transition temperature (FATT), measured in ° C, of several steels designed by the inventor, used for the manufacture of channelers.
- the chemical composition of the "BASE”, “A”, “B ⁇ ” C M , “D”, “E” and “F” alloys can be observed in Table 1.
- Figure 2 shows the effect of different austenising and tempering temperatures and the addition or not of Ti on the flow resistance and the transition temperature (FATT), measured in ° C, of different alloys.
- the chemical composition of the different alloys analyzed can be seen in Table 2.
- Steel 17 (chemical composition E) contains a greater amount of Ti (0.015%) and has been heat treated with the same conditions as the steel stated above.
- alloys A, B, C, D, E, F and G have also been treated with other austenized and tempering temperatures, as indicated in Figure 3.
- the inventor has discovered that the combination of elements such as Nb-V-Mo-Ni-Cr among others, in predetermined amounts, allows obtaining an excellent combination of strength, toughness, hardness, high CTOD values and good strength to hydrogen-induced cracking (HIC) in the base metal; besides allowing to obtain high values of CTOD in the area affected by heat (HAZ) of the welded joint.
- HIC hydrogen-induced cracking
- Step B The next step was to reduce the content of C to 0.061% (Steel B), observing that there was a detriment of both properties evaluated. It was then split again from steel A and the V in its composition (Steel C) was eliminated. Although the transition temperature was slightly improved by this practice, the final strength of the material did not reach the minimum required.
- the next step was to experiment with the addition of Cr.
- the addition of Cr was made to both steel A (obtaining steel D), and steel C (obtaining steel E). Both steels presented improvements in both resistance and transition temperature, although steel D fulfilled the required properties more appropriately.
- the inventor has carried out another series of experiments to check three important factors that affect the properties of the material that forms the channeler: the content of Ti in the alloy, the effect of austenitic grain size and tempering temperature during heat treatment of steel.
- the inventor found that the variation in tempering temperature of the steel at approximately 30 ° C does not produce a significant effect on the mechanical properties of the material, in the case that the alloy does not possess Ti. While in an alloy that has a Ti content of up to 0.015%, a detriment of resistance when going from a tempering temperature of 630 to 660 ° C.
- Carbon is the most economical element with the greatest impact on the mechanical strength of steel, therefore its content cannot be very low. In order to achieve creep resistance greater than or equal to 65 k if it is necessary that the content of this element be keep above 0.06% for thick pipes.
- C is the main element that promotes the hardenability of the material. If the content of this is very low, the temperability of the steel is considerably affected and therefore the promotion of a thick and heterogeneous acicular structure at half the thickness of the pipe will be characteristic. This phenomenon would not allow to achieve adequate resistance for this material in addition to the detriment of toughness.
- the content of this element must not exceed 0, 13%. Therefore the content of C should be 0.06 to 0.13%.
- Mn 1, 00 to 1, 30 M n is an element that increases hardenability in steel, promoting the formation of martensite, as well as the promotion of the MA constituent, which is detrimental to tenacity.
- the Mn promotes a high central segregation in the steel bar from which the tube is laminated.
- Mn is the second element with a higher segregation index, favoring the formation of MnS inclusions and even when steel is treated by Ca, due to the central segregation problem for an Mn content above 1.35%, such inclusions are not eliminated.
- Mn is the second element with the greatest influence on the EC formula (Equivalent Carbon, Formula 1IW), thereby increasing the value of the final EC content.
- the optimum content of Mn must be in the range 1, 00 to 1, 35 and more particularly it must be in the range 1, 05 to 1, 30.
- Silicon is necessary as a deoxidant in the steelmaking process and is also necessary to improve the strength of the material.
- This element like manganese, promotes the segregation of P to grain limits, which is why it is harmful and should be kept as low as possible, preferably below 0.35% by weight.
- Phosphorus exists as an inevitable element in the metallic charge, and a content greater than 0.015% produces segregation in grain edges, which decreases resistance to HIC. It is essential to maintain levels below 0.01 5% to avoid problems of both toughness and hydrogen-induced cracking.
- Molybdenum allows to increase the tempering temperature, also preventing the segregation of embrittlement elements on the edge of austenitic grain.
- Chromium produces hardening by solid solution and increases the hardenability of the material and therefore increases the resistance.
- Cr is an element that is also found in the metallic charge. Therefore, it is desired to have a minimum content of 0.10%, but in parallel, an excess can cause problems of malfunction, so it is advisable to maintain a maximum value of 0.30%.
- V 0.050 to 0.10 This element precipitates in the solid solution in the form of carbides thus increasing the strength of the material, therefore the minimum content must be 0.050%. If the content of this element exceeds 0.10% (or even if it exceeds 0.08%), the fracture toughness of the weld may be affected because an excess of carbides or carbonitrides can be found in the matrix. Therefore, the content must be between 0.050 and 0.10%.
- This element like V, precipitates in the solid solution in the form of carbides or nitrides, thus increasing the strength of the material.
- these carbides or nitrides prevent excessive grain growth.
- An excess content of this element does not bring additional advantages and could also cause the precipitation of compounds that are detrimental to the toughness. Therefore the content of Nb must be between 0.020 and 0.035. Ni 0.30 to 0.45
- Nickel is an element that improves the toughness of the base material and welding, although excessive additions end up saturating this effect. Therefore, the optimum range for thick pipe should be 0.30 to 0.45%, and it has also been found that the optimum Ni content is 0.40%.
- the Cu content In order to achieve good weldability of the material and avoid the appearance of defects that could worsen the quality of the joint, the Cu content must be kept below 0.2%.
- Aluminum acts as a deoxidant in the steelmaking process. It also refines the grain of the material allowing to obtain higher values of toughness. On the other hand, a high content of Al could generate inclusions of the uterine, reducing the toughness of the material. Therefore, the Aluminum content will be limited between 0.015 and 0.040%.
- Ti is an element that is used for deoxidation and for refining grain. In contents greater than 0.020% and in the presence of elements such as N, C can form compounds such as carbonitrides or nitrides of Ti which are detrimental to the transition temperature. As can be seen in Figure 2, it was found that in order to avoid a marked decrease in the transition temperature of the pipe, the Ti content does not have to be greater than 0.02%.
- the optimal austenitic grain size is 9 or 10 according to ASTM.
- the thick steel seamless steel tube containing the detailed chemical composition should have the following balance of characteristic values:
- Shear Area (-10 ° C) 100% D ureza ⁇ 240 HV10 maximum CTOD in the base metal (test at a temperature up to -40 ° C)
- Corrosion Test HI C according to NACE TM0284, with solution A: 1.5% CTR Max. ; CLR 5, 0% Max.
- Another aspect of the present invention is that of disclosing a suitable heat treatment to be carried out on a thick tube with the chemical composition indicated above, in order to achieve the required mechanical properties and corrosion resistance.
- the manufacturing process and specifically the parameters of the heat treatment in conjunction with the chemical composition described, have been developed by the inventor so as to be able to achieve an adequate ratio of mechanical properties and corrosion resistance, in turn how to achieve high mechanical resistance of the material at 1 30 ° C.
- the process used to manufacture the product consists of the following steps:
- This steel must contain in percentage by weight the following elements in the amounts described: C 0.06 to 0.1; Mn 1, 00 to 1, 30; Yes 0.35 max. ; P 0.015 max. ; S 0.003 max. ; Mo 0, 1 0 to 0.20; Cr 0.10 to 0.30; V 0.050 to 0.10; Nb 0.020 to 0.035; Ni 0.30 to 0.45; At 0.01 5 to 0.040; Ti 0.020 max; Cu 0.2 max. and N 0.010 max.
- This steel is then formed into solid bars obtained through continuous curved or vertical casting. Then the drilling of the bar and its subsequent lamination is carried out to its final dimensions.
- the preferred lamination process must be with retained mandrel.
- the tube is subjected to heat treatment. During this treatment the tube is first heated in an austenitized oven to a temperature higher than Ac3.
- the inventor has found that an austenized temperature between 900 and 930 ° C is necessary for the chemical composition described above. This range has been developed to be high enough to achieve a correct dissolution of carbides in the matrix and in turn not too high to avoid excessive grain growth, which then detracts the transition temperature of the pipe.
- the tube leaves the austenitized furnace, it is immediately subjected to external-internal tempering in a tub where the tempering medium is water. Tempering should be carried out in a tube that allows the tube to rotate during immersion in the water, so that a homogeneous structure can be obtained throughout the entire body of the tube. In turn, an automatic alignment of the tube with respect to the water injection nozzle also allows the objectives set to be fulfilled in a better way.
- the next step is the tempering treatment of the tube, a process that grants the final microstructure.
- Said microstructure is what will give the mechanical and corrosion characteristics to the material.
- a high tempering temperature is effective in increasing the toughness of the material since it relieves a significant amount of residual stresses and puts some constituents into solution.
- the tempering temperature must be between 630 ° C and 690 ° C.
- the metal charge is prepared in accordance with the concepts described and melted in an electric arc furnace. During the melting stage of the load up to 1550 ° C, the dephosphorus of the steel is carried out, subsequently de-iced and a new slag is formed to reduce the sulfur content somewhat. Finally it is decarburized to the desired levels and the liquid steel is emptied into the pot.
- the casting in composition and temperature is ready, it is sent to the continuous casting machine or to the ingot casting to carry out the transformation of the liquid steel into a solid bar of the required diameter.
- the product obtained at the end of this stage is an ingot, bar or billet with the chemical composition described above.
- the next step is to reheat the steel billets to the appropriate temperature for drilling and subsequent lamination.
- the mother tube thus obtained is then adjusted to its final dimensions.
- the steel tube is subjected to a tempering and tempering heat treatment according to the parameters detailed above.
- Table 3 presents the different chemical compositions on which the works used to achieve the present invention were based.
- Table 4 establishes the effect of this composition, with the indicated thermal treatments, on the mechanical properties and the corrosion of the product.
- the channeler identified with the number 1 has a chemical composition as detailed in Table 3, that is, C, 0.09; Mn, 1, 1 6; Yes, 0.28; P, 0.01; S, 0.0012; Mo, 0, 133; Cr, 0.20; V, 0.061; Nb, 0.025; Ni, 0.35; To the,
- This same tube has the properties indicated in the subsequent columns for the same number of steel in Table 4, that is, a Thickness of 35 mm, a creep resistance (YS) of 75 Ksi, a breaking strength (UTS ) of 89 Ksi, a ratio between creep resistance and tear strength (YS / UTS) of 0.84, a creep resistance measured at 130 ° C of 69 Ksi, a breaking strength measured at 130 Q C of 82 Ksi, a ratio between creep strength and breakage strength measured at 130 ° C of 0.84, or a crack resistance measured by the CTOD test at -10 "C of 1.37 mm, an absorbed energy measured by the Charpy test at -10 ⁇ C of 440 Joules, a ductile-fragile area of 100%, a hardness of 215 HV10 and a corrosion resistance measured by the HI C test of according to NACE TM0284, with solution A of NACE TM0177 is 1.5% Max for CTR and 5.0% Max for CLR.
