How to dispose of pe pipe

The buried PE pipe is not suitable for passing through the building construction and the foundation of the building. When it must be traversed, the protective casing should be used to maintain the foundation; when the PE pipe is laid below the design elevation of the low surface of the building and the foundation of the building, it cannot be stressed Within the scope of the diffusion angle. The diffusion angle is usually 45°, and PE pipes should be laid below the freezing line; residential areas, industrial areas, and industrial and mining enterprises, and water distribution mains with a nominal outer diameter of not more than 200mm can be laid out along the periphery of the building, and the distance from the outer wall is not suitable for low At 1.00m, PE pipes are not allowed to pass through rainwater, sewage, sewage inspection wells and drainage irrigation channels. The deep layer of soil on the top of PE pipes is not suitable to be less than 0.60m under pedestrian crossings and less than 1.00m under light vehicle roads.

1. The PE pipe of the tap water pipe system in cities and towns is sanitary,  and non-fouling. It is more suitable for urban and rural water supply main pipes and buried pipes. It is safe, hygienic, economical, convenient in construction and long in service life.

2. Urban gas transmission pipelines Because PE pipes have good creep resistance and economy, they have gradually replaced ductile iron pipes for urban gas transmission.

3. The replaceable cement pipe, cast iron pipe and steel pipe are used for the old network reconstruction project. It does not require large-area excavation, and is convenient for construction and low in cost. It can be widely used in the old city pipe network reconstruction.

4. Industrial raw material conveying pipes Chemical, chemical fiber, food, forestry, pharmaceutical, light industry, papermaking, metallurgy and other industrial raw material conveying pipes.

5. Garden greening water supply pipe network Garden greening requires a large number of water pipelines. The flexibility and low cost of PE pipes make it the best choice.

6. Sewage discharge pipe PE pipe has unique corrosion resistance and can be used for industrial wastewater and sewage discharge with low cost and maintenance costs.

7. Mineral sand and mud conveying PE pipelines are highly resistant to stress, abrasion and corrosion, and can be widely used for conveying ores, coal ash and river dredging mud.

8. The PE pipe of agricultural irrigation pipe has smooth inner wall, large flow, can be constructed across roads, has good impact resistance, and is an ideal pipe for agricultural irrigation.

9. Marine pipe PE pipe is light in weight and easy to connect, and can be widely used in water supply and drainage of large ships.

10. The PE pipe for seawater desalination has a long service life and high cost performance, and is widely used in seawater desalination projects.

11. Rural biogas pipelines are being used in large-scale rural biogas projects due to their good economics.

12. Other applications PE pipes can also be widely used in other fields, such as power, communication jackets, farmland irrigation, landfills, geothermal air conditioning, deep-sea aquaculture, buried fire-fighting pipes, and so on.

What is advantage of hdpe over 160 psi pe pipe

HDPE is a ductile material and has exceptional impact strength. HDPE's superior impact strength provides a piping system that is near impervious to impact damage and to damage from improper tapping.High pressure pe pipe.

Product parameters:

Material: high density polyethylene

Executive standard: GB / T13663-2000

Length: 6m, 12m

Service life: more than 50 years

Path range: dn20-dn800mm

Nominal pressure: 0.6-1.6Mpa

Connection method: thermal fusion connection, electric fusion connection

Feature

■ Good sanitary performance: no heavy metal salt stabilizer is added during the processing of PE pipe, the material is no scale layer, no breeding bacteria, and it can solve the secondary pollution of urban drinking water.

■ Excellent corrosion resistance: Except for a few strong oxidants, it can withstand the corrosion of various chemical media; no electrochemical corrosion.

■ Long service life: Under rated temperature and pressure conditions, PE pipes can be used safely for more than 50 years.

■ Good impact resistance: PE pipe has good toughness, high impact strength, and heavy objects directly pressing through the pipeline will not cause the pipeline to break.

■ Reliable connection performance: The strength of the PE pipe's hot-melt or electric fusion interface is higher than that of the pipe body, and the joints will not be broken due to soil movement or live load.

■ Good construction performance: light weight pipeline, simple welding process, convenient construction, and low comprehensive engineering cost.

Connection of pipes:

■ Electric thermal fusion: Adopt special electric thermal welding machine to connect straight pipe and straight pipe, straight pipe and pipe fittings. Generally used for tubes below 160mm.

■ Hot-melt butt connection: It is connected by a special butt welder pipe, which is generally used for pipes above 160mm.

■ Steel-plastic connection: It can be connected by flanges, threaded fasteners, etc.

■ In order to facilitate construction and ensure construction quality, corresponding tools should also be prepared.

How do you connect pe gas pipe to existing steel gas pipe

1. Electric fusion connection bai connection: The electric fusion connection is to put the electric fusion pipe du on the pipe and pipe fittings. The resistance wire on the inner surface of the electric fusion pipe is energized and heated to melt the inner surface of the electric fusion pipe and socket The outer surface of the pipe is melted into one body.

2. Hot-melt socket connection: through the hot-melt connector, the socket end of the pipe and the pipe fitting and the socket end of the pipe fitting are heated and melted at the same time, and the molten socket is inserted into the socket and fixed to the cooling.

3. Hot-melt butt connection: Hot-melt butt connection is a method in which the ends of thermoplastic pipes are heated and melted by a heating plate, butted and fused together, and then cooled and fixed to connect them together. Hot melt butt connection is the most important and traditional connection method for polyethylene pipes and polypropylene pipes. It is generally believed that hot-melt butt joints are suitable for the connection of pipes with diameters above DN63mm or pipes with wall thicknesses above 6mm.
