Definitions

  • the present invention relates to a method of manufacturing plated steel armor wires for reinforcement of tubular pipes flexible for the transport of hydrocarbons, in particular non related ("unbonded flexible pipes"), according to the preamble of claim 1 as well as such a tubular pipe according to the the preamble of claim 10 (see, for example, JP-A-60 255 923).
  • These behaviors are defined in the API 17J and 17B recommendations from the American Petroleum Institute and have metal layers and separate polymeric layers, that is to say, not linked together so as to allow a certain relative displacement between the layers.
  • Such conduct may be smooth inside passage when the passage is directly formed by the sealing sheath (it is then called “smooth” boron ”) or non-smooth passage (" rough bore ”) when further inside the inner sealing sheath a carcass consisting of a staple-wrapped strap with a short pitch which serves to prevent crushing of the driving under external pressure.
  • a carcass consisting of a staple-wrapped strap with a short pitch which serves to prevent crushing of the driving under external pressure.
  • the pipe may optionally include in addition to these layers, other particular layers, a metal band (short-pitched) and forming part of the pressure vault, polymeric sheaths intermediaries, etc.
  • the driving generally comprises at the same time a carcass, a sealing sheath, a pressure vault, plies of tensile armor, and an outer sealing sheath.
  • the armor threads considered are the armor threads pulling armor tablecloths crossed or possibly the form wires or the hoop wires of the pressure vault, which will be called pressure armor wires.
  • pressure armor wires By extension, we will hear also by wire of a form wire obtained according to the method of the invention and which would be intended to be used for the manufacture of a carcass.
  • a corrosion-resistant steel H 2 S is used, but with medium mechanical characteristics for the armor wires of the pressure vault. , and a steel with high mechanical characteristics but not resistant to acid corrosion for traction armor plies.
  • This compromise seems acceptable if the H 2 S corrosion can not reach the layers of tensile armor; for this purpose, an intermediate H 2 S containment sheath separates the pressure vault that will be subjected to H 2 S corrosion and the tensile armor plies, which will not in principle be subjected to this corrosion.
  • safety is not guaranteed because of the risk of piercing the intermediate sheath.
  • the poor mechanical characteristics of the steel used for the pressure vault lead to the obligation to oversize it.
  • the object of the invention is to allow the reinforcement of the pipes flexible, including unbound pipes, by armor wires resistant to corrosion but also with good qualities to allow the use of the pipes at great depth. More specifically, the object of the invention is to find a method of Intimate coating or plating of the steel armor wires, compatible with the requirements of a use for a pipe of the aforementioned type used in acidic environment and in great depth.
  • the invention achieves its goal through a yarn manufacturing process plated steel armor for reinforcement of tubular conduits flexible, in particular unbound, for the transport of hydrocarbons, process of the type in which a veneer coating is intimately associated, by strong pressure, to a steel core, characterized in that the steel of the soul is chosen with medium mechanical characteristics and is what the coating is applied to the soul and intimately associated, then in that the plated wire obtained undergoes rapid quenching at high temperature followed by an income, so as to increase the mechanical characteristics plated wire.
  • the characteristics of steel and veneer coating, as well as the temperature and the time of quenching are selected in a related manner from to elevate the mechanical characteristics of the quenched wire without destroying the strength of the veneer bond.
  • One of the key factors of the invention is the rapidity of the high temperature heat treatment which, in connection with the other parameters, makes it possible to minimize the constraints at the level of the between the steel and the coating, in particular by avoiding the migration of the carbon and iron steel in the bond and coating.
  • the core of the armor wire is medium resistance, that is to say whose resistance Rm is between 500 and 1000 MPa, advantageously between 800 and 900 MPa. It must be a "hardenable" steel (able to undergo tempering improving its mechanical characteristics, the quench consisting, as we know, of a curing by heat treatment: austenization + cooling) carbon, alloyed or weakly alloyed.
  • the anti-corrosive coating is for example made of titanium or alloys of titanium, stainless steel, nickel or nickel alloys.
  • the veneer is made mechanically cold after a preparation adequate (mechanical or chemical deoxidation of surfaces), according to a technique allowing an intimate connection by pressure (for example co-extrusion or colaminage).
  • the steel thus coated is subjected to a treatment thermal device with a short temper at high temperature and an income in order to minimize the constraints on the connection between steel and coating.
  • the heat treatment according to the invention makes it possible to improve the characteristics of the bond, restore the characteristics of ductility plating and to obtain the high mechanical properties of the metal of basis for the applications envisaged for this type of product.
  • This heat treatment is characterized by a thermal cycle at high temperature (900 ° C to 1100 ° C) short (a few seconds to a few tens of seconds) followed by rapid cooling and treatment at a temperature of the order of 400 ° C to 700 ° C and which is adjusted in depending on the desired mechanical characteristics, the income being over a period of a few minutes, advantageously between 10 and 20 minutes.
  • This heat treatment has the following effects, depending on the components of the armor:
  • the treatment restores ductility without leading to precipitation prejudicial to the resistance to corrosion.
  • connection it allows an improvement of the resistance by relaxation of rolling or extrusion and diffusion stresses metallic.
  • income also allows a complementary improvement of the ductility by the relaxation of the differential stresses related to quenching.
  • the heat treatment will make it possible to obtain a hardened tempered structure associating very high characteristics mechanical properties (Rm greater than 1000 MPa and preferably 1400 MPa less) and sufficient ductility for the intended applications (approximately 5% elongation).
  • the invention also relates to a flexible tubular conduit for the transporting hydrocarbons, incorporating at least some armor threads manufactured according to the aforementioned manufacturing process. More precisely, the invention relates to a flexible tubular pipe for transport hydrocarbons, of the type comprising polymeric layers and unbound metal layers, metal layers with wound armor, characterized in that at least some of the armor threads are tempered and returned and are manufactured according to the method of the preceding claims.
  • the invention is intended in particular to conduct of the type comprising at least one carcass, an inner sheath, a pressure vault comprising armor wires of pressure, webs consisting of tensile armor wires and a sheath exterior, characterized in that at least some of the armor wires are manufactured according to the method of the invention.
  • Figure 1 shows a "rough bore” type pipe that includes from inside to outside: a metal carcass 1, usually made by a staple strap wound with a short pitch and intended for resistance crushing under external pressure; an internal sealing sheath polymeric 2, a metal pressure vault, constituted here so traditional winding with a short pitch helix (winding angle generally close to 90 ° to the axis of the pipe) of a wire stapled form metal 3 doubled by short pitch helical winding of a wire 4, an armor 5 resistant to axial traction in the direction longitudinal direction of the pipe and typically consists of a pair of cross plies of long armor pull wire 6,7 (typically less than 55 ° with respect to the axis of the pipe), and a outer polymer sheath 8.
  • Other layers such as other armor 9 and an intermediate sheath 10 may be provided according to the type and destination of the pipe.
  • the invention relates to the plating of the traction armor wires 6,7 also although pressure armor wires 3, 4 (where applicable), according to a treatment that is illustrated in Figure 2.
  • the starting wire 20 consists of a base metal core 21 to average mechanical characteristics (for example Rm from 800 to 900 MPa) and a coating 22 of metal plating.
  • the base metal can be, for example, a base steel type chrome silicon (55SiCr V) in the state globulized to allow plating.
  • the plating metal can be for example a nickel base (NiCrMo series 6x according to AISI) or an alloy nickel (8x series).
  • Starting wire 20 passes through a coextrusion die 23, from which it emerges having the coating 22 closely related to the soul. so plated wire goes into a post 24 heat treatment at high temperature, typically at least 800 ° C and preferably at 1100 ° C, by for example by heating the wire by induction.
  • This treatment is fast (from a few seconds to a few minutes at the most). There occurs a austenitization of the base steel.
  • This treatment is followed by rapid quenching in a quench station (for example by air, water or oil) which accompanied by a controlled martensitic transformation and thus allows obtaining high mechanical characteristics, with a Rm of the order 2000 MPa.
  • a quench station for example by air, water or oil
  • the speed of the treatment makes it impossible to leave to diffuse harmful elements (iron, carbon) in the link which would degrade the quality of it and degrade the resistance to corrosion of the veneer.
  • Induction heating is advantageous not only for its speed but also because it makes it possible to overcome problems related to the possible reflection of the coating.
