Abstract

The utility model discloses a lining titanium composite metal tube which comprises a carbon steel base steel tube layer (1). The lining titanium composite metal tube is characterized in that a titanium corrosion resisting layer (2) is lined on the carbon steel base steel tube layer (1), and the carbon steel base steel tube layer (1) is connected with the titanium corrosion resisting layer (2) through a hydrostatic pressure expanding composite process in a composite mode. According to the lining titanium composite metal tube, the problem that costs are high due to the fact that high-cost titanium metal tubes which are made of pure titanium or titanium alloy materials are used to guarantee that the metal tubes are corrosion resistant in a plurality of media, especially in neutral and oxidizability media is solved.

Description

A kind of titanium lined composite metal pipe
Technical field
The present invention relates to metal tube complex technique field, be specifically related to a kind of titanium lined composite metal pipe.
Background technique
At present, composite steel tube is soaring year by year in the use amount of all trades and professions.Carry out compoundly according to the corresponding inner liner metal material of the different choice of composite steel tube fed sheet of a media, this is an industry general knowledge.The technical pure titanium or titanium alloy has outstanding decay resistance, is the preferred material of numerous chemical corrosion environment, comprises chloride solution, seawater, the chloro bleaching agent of oxidation.Titanium alloy also has characteristics such as low density (density p=4.51 gram/cubic centimetres), high tenacity.Titanium has very strong corrosion resistance in more medium, especially the corrosion resistance in neutrality and Oxidant is very strong.Along with high speed development of national economy, market is more and more for the demand of titanium or titanium alloy, because the rare and manufacture cost of resource, the price of titanium material is high always, and cost is very high beyond doubt for the user for this point.Although the welding performance of titanium or titanium alloy itself is good; But the titanium material is difficult to weld together with common carbon steel; Up to now the domestic composite steel tube of not finding the titanium lined metal as yet if use the composite metal pipe of being processed by pure titanium or titanium alloy material, will improve user cost greatly.
Summary of the invention
The object of the invention provides a kind of titanium lined composite metal pipe; The utility model has solved in the existing technology possesses corrosion resistance for metal tube is had in the application than multimedium; Especially the corrosion resistance in neutrality and Oxidant; And adopt the higher Ti metal pipe of processing by pure titanium or titanium alloy material of cost, cause the high problem of cost.
The present invention realizes through following technological scheme:
A kind of titanium lined composite metal pipe; Comprise plain steel steel pipe layer (1); It is characterized in that: said plain steel steel pipe layer (1) titanium lined anti-corrosion layer (2), plain steel steel pipe layer (1) is through hydrostatic pressing hole enlargement combination process and compound connection of titanium anti-corrosion layer (2).
The further technological scheme of the present invention is:
Said titanium anti-corrosion layer (2) exposure is in plain steel steel pipe layer (1), and formation step (3), and step (3) is located to form bevel for welding (4) through welding, and bevel for welding (4) heap is tall and big in 3/5 of plain steel steel pipe layer (1) wall thickness.
The present invention's technological scheme further is:
The thickness range of said titanium anti-corrosion layer (2) is 1.0 mm~2.0mm; Said titanium anti-corrosion layer (2) adopts the trade mark to process for the TA2 titanium metal material.
The present invention compared with prior art; Has obvious advantage; Because the unit price of plain steel steel pipe far below the cost of pure titanium or titanium alloy material, so the compound unit price of formed composite metal pipe later on of plain steel steel pipe and titanium pipe can be processed the titanium pipe far below the pure titanium or the titanium alloy material of equal specification and wall thickness, can reduce cost in the engineering practical application significantly; And can promote the use of on a large scale, have very high economic benefit and social benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises plain steel steel pipe layer 1, plain steel steel pipe layer 1 titanium lined anti-corrosion layer 2, and plain steel steel pipe layer 1 is through hydrostatic pressing hole enlargement combination process and 2 compound connections of titanium anti-corrosion layer; 2 exposures of titanium anti-corrosion layer are in plain steel steel pipe layer 1, and formation step 3, and step 3 places form bevel for welding 4 through welding, and bevel for welding 4 heaps are tall and big in 3/5 of plain steel steel pipe layer 1 wall thickness; The thickness range of titanium anti-corrosion layer 2 is 1.0 mm~2.0mm; Titanium anti-corrosion layer 2 adopts the trade mark to process for the TA2 titanium metal material.
The composite bimetal pipe hydrostatic pressing hole enlargement combination process step that is adopted in the utility model is following:
After matrix steel tube and the assembling of liner corrosion resisting alloy pipe are accomplished; Liner corrosion resisting alloy pipe two ends adopt hemispherical head to dock; The spot welding of going forward side by side location; For guaranteeing the intensity of weld seam, the material of hemispherical head should be consistent with the material of liner corrosion resisting alloy pipe, and the wall thickness of hemispherical head should be greater than the twice of liner corrosion resisting alloy thickness of pipe wall; Adopt the argon arc welding of tungsten level that hemispherical head and liner corrosion resisting alloy pipe are carried out the circumferential weld welding, carry out air protection in the welding process simultaneously; According to wall thickness, diameter, the material of matrix steel tube, (δ/f) * E*T/D-t calculates the maximum permissible stress of matrix steel tube, and above-mentioned formula P2 representes allowable pressure in matrix steel tube 1 pipe by formula P2=2* then; δ representes yield strength, and E representes quality coefficient, and F representes safety coefficient; D representes matrix steel tube 1 external diameter; T representes matrix steel tube 1 wall thickness, and quality coefficient E span is 0.8~1.0, and safety coefficient F value is 1.5; Calculating the maximum permissible stress of matrix steel tube according to above-mentioned formula, confirm the pressure that the hydrostatic pressing hole enlargement is compound, is the adhesive strength that guarantees composite bimetal pipe, and the compound pressure of hydrostatic pressing hole enlargement should reach or near 90% of matrix steel tube maximum permissible stress; According to the compound pressure of confirming of hydrostatic pressing hole enlargement; The water injection valve that hemispherical head is provided with through the numerical control hydraulic press hydraulic pressure of in liner corrosion resistant alloy pipe, annotating; The speed that control is simultaneously boosted after pressure reaches setting value, and is done pressurize and is handled; The rate of rise generally is controlled at less than 0.1Mpa/min, and the dwell time was not less than ten minutes; Hydraulic pressure in the liner corrosion resistant alloy pipe carries out pressure release through the outlet valve that hemispherical head is provided with, and pressure release makes the two ends hemispherical head separate with liner corrosion resistant alloy pipe through cutting after accomplishing, and final matrix steel tube and liner corrosion resisting alloy pipe are accomplished compound.
The utility model does not relate to all identical with the existing technology existing technology that maybe can adopt of part to be realized.
