Abstract
The utility model discloses a bimetallic composite welded pipe with a straight seam. The welded pipe is formed by straight seam forming welding after a composition of an anti-corrosive alloy internal layer (2) and a carbon steel external layer (1). The anti-corrosive alloy internal layer and the carbon steel external layer are composed in a way of blast plus hot rolling. A formed composite layer is made from stainless steel material of 316 L, 304 L and 2205 or titanium and titanium alloy material; the thickness of the composite layer is 1 to 2mm; and a substrate layer is formed by pipeline steel material of X52, X60, X 65 and X 70. In the bimetallic composite welded pipe with straight seam, anti-corrosive alloy internal layer and the carbon steel external layer are composed in the way of blast plus hot rolling and the substrate layer is tightly and fixedly combined with the composite layer without a gap, so deficiencies of a composite pipe formed by mechanical combination in the prior art are overcome; and manufacturing technology of the bimetallic composite welded pipe with the straight seam is simple, so industrial volume production can be achieved and product cost can be greatly reduced.
Description
Technical field
The utility model belongs to composite welded pipe manufacturing technology field, is specifically related to a kind of vertical masonry joint 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 the inefficacy and the accident that cause conveyance conduit, corrosive pipeline environment has proposed higher, more harsh corrosion-resistant requirement to conveyance conduit, and adopting corrosion-resistant composite pipe is one of most economical mode.The liner two-phase stainless steel composite steel pipe that domestic production is at present used is mostly a kind of composite steel tube of mechanical bond, because carbon steel base layer and stainless steel double layer are a kind of mechanical bond states, between base tube and bushing pipe, there is gap, especially at high temperature, it will cause internal coated layer unstability, bubbling because expansion coefficient difference and interlayer between carbon steel and stainless steel exist gas, when local etching appears in bushing pipe, aggressive medium can infiltrate the gap between base tube and bushing pipe, accelerate corrosive pipeline, finally affect the Security of pipeline.
Model utility content
The purpose of this utility model is to provide a kind of vertical masonry joint bimetal composite welded pipe of transfer oil rock gas, overcome the defect of the composite pipe of current mechanical bond, and manufacturing process is simple, can realize industrialized batch production.
The technical solution adopted in the utility model is: a kind of vertical masonry joint bimetal composite welded pipe, described welded tube by corrosion resistant alloy internal layer and carbon steel outer compound after again vertical masonry joint moulding welding form.
Described corrosion resistant alloy internal 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: the utility model corrosion resistant alloy internal layer and carbon steel skin are combined with each other in " blast+hot rolling " mode, the firmly tight gapless of combination between basic unit and multiple layer, overcome the defect of the composite pipe of current mechanical bond, and manufacturing process is simple, can realize industrialized batch production, greatly reduce product cost.

Fig. 1 is the utility model structural representation,
Fig. 2 is the utility model cross-sectional configuration schematic diagram.
Embodiment:
1,2 a kind of embodiment of the present utility model is described by reference to the accompanying drawings.
A vertical masonry joint bimetal composite welded pipe, described welded tube by corrosion resistant alloy internal layer 2 and carbon steel outer 1 compound after again vertical masonry joint moulding welding form.
Described corrosion resistant alloy internal layer and carbon steel skin are combined with each other in " blast+hot rolling " mode.
Described multiple layer is stainless steel materials 316L, 304L, 2205, or titanium or titanium alloy sheet material, and thickness is 1-2mm; Described basic unit is X52, X60, X65, X70 pipe line steel sheet material.
Manufacturing process: adopt prior art, in " blast+hot rolling " mode, manufacturing multiple layer is corrosion resistant alloy, basic unit is the bi-metal composite panel of carbon steel, then its corrosion resistant alloy one is faced up, carbon steel one faces down, to sheet material align, surface treatment, and to sheet material both sides according to different welding procedures, process different bevel for weldings, adopt JCOE moulding process that composite board is shaped to vertical masonry joint tubulose, then adopt welding procedure that vertical masonry joint 3 welding be can be made into Fu Cengnei basic unit vertical masonry joint bimetal composite welded pipe outside.
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.
