4. Buried polyethylene (PE) pipes for gas

Buried polyethylene pipes for gas use are products that are extruded from special polyethylene as raw material.It is safe to use, has a low leakage rate, and has good corrosion resistance; it has a long service life, light weight, high strength, good toughness, convenient construction, wide range of applications, and great social benefits.It is mainly used for natural gas and artificial gas buried gas pipelines.

Features：

1) The installation process is simple and easy to operate

There are two connection methods for PE pipes. One is the electric melt connection, which is generally suitable for pipe diameters less than De110; the other is the hot melt connection, which is generally suitable for pipe diameters not less than De110, and there is no need for sleeve fittings in the docking.The above two connection operation methods can be mastered in short-term training, the welding quality can be guaranteed, and the construction progress is fast.In addition, it is possible to open a three-way operation with air in the running gas pipeline network. This process cannot be achieved by using steel pipes as gas pipelines.

2) Anticorrosive treatment, strong corrosion resistance, long life buried in the ground

According to relevant documents, after 60 years of use in foreign PE buried sites, they are dug up and re-welded. The welding and body quality can also meet the quality index requirements of PE pipes; PE pipes do not need to be anticorrosive.The general design life of steel pipes is 20 years.

3) Strong engineering adaptability

There are many professional pipelines in the courtyards of municipal engineering and residential areas, and the pipe position is tight. In this complex construction environment, it has a kind of flexibility, and it can be naturally bent and avoided under the allowable radius of curvature. Winding laying and installation.

4) Low investment cost

①The advantage of the price of pipes over the currently commonly used gas steel pipes is that it is well known that PE pipes with large diameters can be connected by hot melt, saving pipe fitting costs, and have a long life and no need for anticorrosion. The comprehensive price is lower than that of steel pipe investment.

②The PE pipe has strong flexibility. It can be prefabricated on the ground and then placed in the pipe ditch. There is no need to make a work pit. Therefore, the earthwork of the PE pipe construction pipe ditch is smaller than that of the steel pipe construction pipe ditch.

5. PE pipe for water supply

PE (Polyethylene) material is widely used in the field of water supply pipe manufacturing due to its high strength, corrosion resistance, non-toxic and other characteristics.Because it will not rust, it is an ideal pipe to replace ordinary iron water supply pipes.Plastic pipes in our country are developing rapidly, and the quality is constantly improving.Among them, polyethylene PE pipes are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas pipelines, electrician and telecommunications protective sleeves, industrial pipes, agricultural pipes, etc. due to their unique advantages.It is mainly used in urban water supply, urban gas supply and farmland irrigation and other fields.

Features：

1) Corrosion resistance

Polyethylene has excellent corrosion resistance, good hygiene properties and long service life.

Polyethylene is a non-inert material, except for a small amount of strong oxidizing agents, it is resistant to a variety of chemicals, and it is not easy to breed bacteria.The service life of polyethylene pipes is more than 50 years.

2) Flexibility

Polyethylene has unique flexibility and excellent scratch resistance.

The flexibility of polyethylene piping system has great technical and economic value.The flexibility of polyethylene is an important property, which greatly improves the value of the material for pipeline engineering.Good flexibility allows polyethylene pipes to be coiled and supplied in a longer length, avoiding a large number of joints and pipe fittings.

6. PE double-wall corrugated pipe for buried drainage

PE double-wall corrugated pipe for buried drainage is a new type of lightweight pipe made of polyethylene as raw material, extruded and processed by special molding process, with smooth inner wall and closed corrugated outer wall.
