1) Good hygienic performance: PE pipe processing without adding heavy metal salt stabilizer, non-toxic material, no scaling layer, no bacteria, a good solution to the secondary pollution of urban drinking water.
2) Good corrosion resistance: Except for a few strong oxidants, it can resist the erosion of various chemical media; no electrochemical corrosion.
3) Long service life: Under rated temperature and pressure conditions, PE pipeline can be used safely for more than 50 years.
4) Better impact resistance: PE pipe has good toughness, high impact strength, heavy objects directly pressed through the pipeline, will not lead to pipeline rupture.
5) Reliable connection performance: PE pipe hot-melt or electric-melt interface strength is higher than the pipe body, the joint will not be broken due to soil movement or live load.
6) Good construction performance: light pipeline, simple welding process, convenient construction, low comprehensive cost of the project.
Pipeline Connection:
1) Electric-thermal weldability: The straight pipe and straight pipe, straight pipe and pipe fittings are connected by special electric-thermal welder. Usually used for pipes under 160mm.
2) Hot-melt butt joint: Use special butt welder pipe connection, generally used for more than 160mm pipes.
3) Steel-plastic connection: flange, thread and other methods can be used to connect.
Application:
Hesu Pipe Industry's high-performance high-density polyethylene water pressure pipes are suitable for municipal and industrial transmission systems for potable water, sewer, drain, mining, irrigation, and reclaimed water.
Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings. According to the application: 1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc. 2. changing the direction of the pipe: bends, bends. 3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe. 4. pipe fittings with additional piping branches: three links, four links. 5. pipe fittings for pipe sealing: gasket, raw material belt, thread hemp, flange blind plate, pipe plug, blind plate, head, welding plug. 6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc. According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings. Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.
