Described New Large Caliber revolves plastic composite, comprise main body tube, main body tube is followed successively by revolve from the inside to the outside moulds layer, steel pipe, glass fiber winding layer, it is characterized in that the steel pipe two ends of main body tube connect respectively and arrange Stainless Steel Tube, Stainless Steel Tube is connected with the internal surface of fastener for connection end and arranges stainless steel back-up ring.
Described New Large Caliber revolves plastic composite, it is characterized in that adopting respectively between described Stainless Steel Tube and steel pipe, stainless steel back-up ring be welded to connect fixing.
Described New Large Caliber revolves plastic composite, and it is characterized in that the external diameter of described Stainless Steel Tube, wall thickness are identical with steel pipe, the wall thickness of stainless steel back-up ring is greater than the thickness revolving and mould layer.
Described New Large Caliber revolves plastic composite, it is characterized in that revolving to mould between layer and steel pipe and arranging wire netting of described main body tube, and wire netting interlocking is moulded in layer and is welded and fixed with the inwall of steel pipe revolving.
Above-mentioned New Large Caliber revolves plastic composite, the linkage structure adopting stainless steel to dock engineering pipeline substitutes traditional Flange joint, novel, rational in infrastructure, avoid any existence that may cause the hidden danger of leakage, pipeline manufacture and maintenance cost can be reduced, guarantee that the normal economy of pipeline uses; Production process can simplify port sealing technique, the reduction manufacture cost of revolving and moulding production process; Directly with the tangent support between two of pipeline cylindrical during stacking, save remarkable benefit in storage and transit link space, obviously can reduce carrying cost; Comprehensively can dock at construction connection procedure, and duct length adjustment can be carried out according to actual laying length, simplify work progress.
Accompanying drawing explanation
Fig. 1 is the structural representation that New Large Caliber described in the utility model revolves plastic composite;
Fig. 2 is the linkage structure schematic diagram of the utility model in engineering construction;
In figure: 1-main body tube, 11-glass fiber winding layer, 12-steel pipe, 13-wire netting, 14-revolve and mould layer, 2-stainless steel back-up ring, 3-Stainless Steel Tube, 4-auxiliary glass fiber winding layer.
Embodiment
Now in conjunction with Figure of description, describe embodiment of the present utility model in detail:
As shown be New Large Caliber and revolve plastic composite, main body tube 1 is followed successively by revolve from the inside to the outside moulds layer 14, steel pipe 12, glass fiber winding layer 11, revolve to mould between layer 14 and steel pipe 12 and arrange wire netting 13, wire netting 13 is rabbeted and is moulded in layer 14 and be welded and fixed with the inwall of steel pipe 12 revolving, and wire netting 13 interlocking being fixed by welding in steel pipe 12 inwall is revolved and moulded layer 14 and can effectively promote the cohesion of revolving and moulding layer 14; Steel pipe 12 two ends connect arrange Stainless Steel Tube 3 respectively by the modes of welding, and external diameter, the wall thickness of Stainless Steel Tube 3 are identical with steel pipe 12; The internal surface of Stainless Steel Tube 3 and the connecting end of steel pipe 12 is connected by welding manner and arranges stainless steel back-up ring 2, the wall thickness of stainless steel back-up ring 2 is greater than the thickness revolving and mould layer 14, revolving to mould in production process and can effectively prevent plastic raw material excessive or cause port out-of-flatness at pipeline, simplify and revolve the port sealing technique of moulding production process, reduce cost of production.
Apply New Large Caliber described in the utility model and revolve plastic composite when carrying out pipeline laying construction, only need by Stainless Steel Tube 3 butt welding of adjacent channel two ends, under such Placement, the fine setting of actual laying length can be carried out by cutting Stainless Steel Tube 3, in connection procedure, adjacent channel is comprehensive docking, no longer need to rotate heavy steel pipe and carry out alignment flange bolt connecting hole, simplify work progress; After adjacent Stainless Steel Tube 3 has docked, arrange corresponding auxiliary glass fiber winding layer 4 on the surface of Stainless Steel Tube 3 by the manual mode be wound around, Stainless Steel Tube 3 can be protected further; Adopt adjacent Stainless Steel Tube 3 butt welding; and have the auxiliary glass fiber winding layer 4 of Stainless Steel Tube 3 outside to protect Stainless Steel Tube 3; just there is not any hidden danger that may cause leakage at pipeline link position, pipe-line maintenance cost can be reduced, guarantee that the normal economy of pipeline uses.
