Abstract
The utility model relates to a steel-plastic compound wearable pipe with ultra-high molecular weight polyethylene. The steel-plastic compound wearable pipe is characterized in that an ultra-high molecular weight polyethylene pipe is combined on the inner wall of a steel-made pipe; and the flangings on both ends of the ultra-high molecular weight polyethylene pipe are combined with the flanges at both ends of the steel-made pipe. The steel-made pipe can adopt a steel elbow, a steel T-piece or cross tee, or a steel special pipe. The steel-plastic compound wearable pipe can be used in high-pressure pipes and has high resistance to abrasion, corrosion and scaling, thereby greatly widening the application range of the pipe and prolonging the service life of the pipe. The steel-plastic compound wearable pipe can be used in the fields of electric power, mines, coal mines, and so on, and has good effect.
Description
Technical field
The utility model relates to a kind of polyethylene steel-plastic complex abrasion-proof pipe fitting.
Background technique
Ultrahigh molecular weight polyethylene tubing is carried at powder, slurry has excellent abrasion resistance properties, but pipe fitting can only be used in (the general 5kg/C m of low pressure place
2Below), particularly threeway, special-shaped part.Limit because of welding condition, be not suitable for pressure duct, and operational safety is poor.Steel pipe fittings has characteristics such as pressure-bearing height, anti-ruled area be good, but not wear-resisting, not corrosion-resistant, easy fouling.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of ultrahigh molecular weight polyethylene steel-plastic complex abrasion-proof pipe fitting, and steel pipe fittings and superhigh molecular weight polyethylene pipe spare are realized having complementary advantages, and expands the application space greatly.
A kind of ultrahigh molecular weight polyethylene steel-plastic complex abrasion-proof of the utility model pipe fitting is characterized in that being compounded with superhigh molecular weight polyethylene pipe spare at the inwall of steel pipe fitting, and the two ends flange of superhigh molecular weight polyethylene pipe spare and two end flange of steel pipe fitting are compound.
Described steel pipe fittings can be steel elbow, steel threeway, four-way or steel section tube etc.
Between steel pipe fitting and superhigh molecular weight polyethylene pipe spare, can be added with thermal-protective material, when particularly using as main line.
The complex method of ultrahigh molecular weight polyethylene steel-plastic composite elbow is earlier steel elbow two ends to be welded flange, ultra-high molecular weight polyethylene elbow is stretched through powerful again, and in the steel elbow, both matching gaps are at 1-3mm.After the two compound getting well ultra-high molecular weight polyethylene elbow two ends flange and steel elbow flange are fitted.
The making method of the compound threeway of ultrahigh molecular weight polyethylene steel-plastic, four-way, special-shaped part is: ultrahigh molecular weight polyethylene tubing is welded into threeway, four-way, special-shaped part, the steel pipe fittings main line is severed along axis, dissecing is two; The superhigh molecular weight polyethylene pipe spare that makes is placed in the steel pipe fitting after dissecing, and adds thermal-protective material at the two and coat; After coating well, will dissect part to be welded into one with electric welding; Steel pipe fittings is welded flange, again the jointing flange is got final product.
Advantage of the present utility model:
Composite steel-plastic pipe fitting can be applicable in the high pressure pipe line, can solve wear-resisting, corrosion-resistant and scale problems, widens the pipe fitting application greatly, improves pipe fitting working life.On probation in fields such as electric power, mine, collieries, effect is obvious.
Description of drawings
Fig. 1 is a ultrahigh molecular weight polyethylene steel-plastic composite elbow structural representation;
Fig. 2 is a ultrahigh molecular weight polyethylene steel-plastic composite pipe structure schematic representation.
Among the figure: 1 steel elbow, 2 ultra-high molecular weight polyethylene elbows, 3 flanges, 4 flange, 5 steel pipe fitting main lines, 6 thermal-protective materials, 7 superhigh molecular weight polyethylene pipe spare main lines, 8 superhigh molecular weight polyethylene pipe spare branch lines, 9 steel pipe fitting branch lines
Embodiment
As Fig. 1, the ultrahigh molecular weight polyethylene steel-plastic composite elbow, earlier steel elbow 1 two ends are welded flange 3, again ultra-high molecular weight polyethylene elbow 2 is stretched through powerful, in steel elbow 1, both matching gaps are compound with two end flange 3 of steel pipe fitting at the two ends of 1-3mm. ultra-high molecular weight polyethylene elbow flange 4.
As Fig. 2, ultrahigh molecular weight polyethylene tubing and steel pipe are welded into threeway, four-way or special-shaped part respectively, earlier steel pipe fitting main line 5 is severed along axis, dissecing is two; Again the superhigh molecular weight polyethylene pipe main line 7 that makes is placed on (it is interior simultaneously superhigh molecular weight polyethylene pipe spare branch line 8 to be enclosed within steel pipe fitting branch line 9) in the steel pipe fitting after dissecing, is coating (not injuring superhigh molecular weight polyethylene pipe spare when welding) in superhigh molecular weight polyethylene pipe spare and the two interpolation thermal-protective material 6 of superhigh molecular weight polyethylene pipe spare on the main line for assurance; After coating well, will dissect part to be welded into one with electric welding; Steel pipe fittings is welded flange, again jointing flange 4 is got final product.
Can adopt to process behind the continuous extruding pipe material of the polyvinyl resin with super-high molecular weight of viscosity average molecular weigh more than 1,500,000 and be superhigh molecular weight polyethylene pipe spare.
