Abstract
The utility model provides a spiral seam thermo-metal composite welded pipe, wherein an anti-corrosion alloy inner layer and a carbon steel outer layer are compounded and then spirally shaped and welded together to form the spiral seam thermo-metal composite welded pipe. The anti-corrosion alloy inner layer and the carbon steel outer layer are compounded together through the process of explosion and hot rolling. The inner layer is made from stainless steel plates of 316L, 304L and 2205, or titanium and titanium alloy plates, and the thickness of the inner layer is 1-2 mm. The outer layer is made from pipeline steel plates of X52, X60, X65 and X70. According to the technical scheme of the utility model, thermo-metal composite pipes of different diameters can be manufactured by composite rolled plates of a single width, and the application field of thermo-metal composite pipes is expanded. Meanwhile, the spiral seam thermo-metal composite welded pipe is simple in manufacturing process, and the industrialized mass production of the spiral seam thermo-metal composite welded pipe is also realized.
Description
Technical field
The utility model belongs to composite welded pipe manufacturing technology field, is specifically related to a kind of helix seam bimetal composite welded pipe.
Background technique
H in oil transportation, gas pipeline
2s, CO
2can cause the serious homogeneous corrosion of pipeline, pitting corrosion, sulfide-stress cracking and hydrogen induced cracking (HIC), thereby cause inefficacy and the accident of conveyance conduit, adopting corrosion-resistant composite pipe is one of most economical mode.Adopting price is the direction of corrosion-resistant transportation pipe material development far below stainless composite bimetal pipe, and owing to being subject to the restriction of composite board width, the composite pipe of vertical masonry joint moulding cannot meet user's needs.
Model utility content
The utility model provides a kind of helix seam bimetal composite welded pipe, has realized the composite bimetal pipe that produces different tube diameters with the compound roll bending of same width, has widened the application of composite bimetal pipe.And manufacturing process is simple, can realize industrialized batch production.
The technical solution adopted in the utility model is: described welded tube by corrosion resistant alloy Inner layer and carbon steel outer compound after again spiral forming welding form.
Described corrosion resistant alloy Inner layer and carbon steel skin are combined with each other in " blast+hot rolling " mode.
Described internal layer is stainless steel materials 316L, 304L, 2205, or titanium or titanium alloy sheet material, and thickness is 1-2mm; Described skin is X52, X60, X65, X70 pipe line steel sheet material.
The advantage the utlity model has and effect: realized the composite bimetal pipe that produces different tube diameters with the compound roll bending of same width, widened the application of composite bimetal pipe.And manufacturing process is simple, can realize industrialized batch production.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation, and Fig. 2 is the utility model cross-sectional configuration schematic diagram, and Fig. 3 is the utility model X-type bevel for welding structural representation.
Embodiment:
1,2,3 a kind of embodiment of the present utility model is described by reference to the accompanying drawings.
A bimetal composite welded pipe, described welded tube by corrosion resistant alloy Inner layer and carbon steel outer compound after again spiral forming welding form.Described corrosion resistant alloy Inner layer 2 and carbon steel skin 1 are combined with each other in " blast+hot rolling " mode.Described internal layer is stainless steel materials 316L, 304L, 2205, or titanium or titanium alloy sheet material, and thickness is 1-2mm; Described skin is X52, X60, X65, X70 pipe line steel sheet material.Manufacture method:
The first step: the bi-metal composite panel corrosion resistant alloy one that " blast+hot rolling " technique is made face up carbon steel one face down align, surface treatment, and at sheet material both sides processing X-type bevel for welding;
Second step: the bi-metal composite panel that is processed with X-type bevel for welding is sent into helix tube molding machine group continuously and bend to gradually tubulose, and form helix seam 3;
The 3rd step: the helix seam 3 to moulding adopts MAG welding procedure to carry out the continuous prewelding of transition layer in pipe, can adjust the geometrical shape of steel pipe at any time in prewelding process;
The 4th step: adopt MAG or SAW welding procedure, carry out the continuous welding of carbon steel skin 1 outside pipe;
The 5th step: adopt TIG welding procedure in pipe to 2 continuous weldings of corrosion resistant alloy internal layer;
The 6th step: form product through sizing, detection, reprocessing.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, thus all equivalent variations of being done with content described in the utility model claim, within all should being included in the utility model claim scope.
