The plastic pipe is generally made of synthetic resin, that is, polyester as a raw material, and is added to a stabilizer, a lubricant, a plasticizer, etc., and is formed by extrusion in a pipe making machine by a "plastic" method. Because of its light weight, corrosion resistance, beautiful appearance, no bad smell, easy processing and convenient construction, it has been widely used in construction projects. The common plastic pipes in life are as follows:

PE water supply pipe

PE (polyethylene) materials are widely used in the field of water supply pipe manufacturing due to their high strength, corrosion resistance and non-toxicity. Because it does not rust, it is an ideal pipe to replace the ordinary iron water supply pipe.

Performance characteristics:

1. Corrosion resistance: Polyethylene has excellent corrosion resistance, good hygienic performance and long service life.

2. Flexibility: Polyethylene has unique flexibility and excellent scratch resistance.

3, low temperature resistance: polyethylene has a very outstanding low temperature resistance.

4. Fracture toughness: Polyethylene has good rapid crack growth and fracture toughness.

PE gas pipe

PE pipe for gas is a traditional steel pipe, PVC gas replacement product, gas pipe must bear a certain pressure, usually choose a PE resin with large molecular weight and good mechanical properties, such as HDPE resin.

Performance characteristics:

1. Excellent corrosion resistance

2, long service life

3, better impact resistance

4, reliable connection performance

5, good construction performance

PE mining pipe

The ultra-high molecular weight polyethylene pipe used in coal mine underground is made by modifying ultra-high molecular weight polyethylene as raw material and extruded through a special extruder. Ultra High Molecular Weight Polyethylene (UHMWPE) is a linear structural polyethylene with a viscosity average molecular weight of more than 1.5 million. It is called "magic plastic" and it concentrates on the advantages of various plastics.

Performance characteristics:

1. Excellent impact performance

2, wear resistance

3, good tensile performance

4, corrosion resistance

5, very low friction coefficient, small fluid resistance

6, not easy to scale

7, easy to connect

8, flame retardant, antistatic performance is stable

9, long service life

Application areas:

Polyethylene pipe used in coal mines is mainly used for underground coal supply and drainage, ventilation, coal slurry transportation, gas drainage and so on.

PE-RT floor heating pipe

It is a special heating pipe made of PE-RT (Polyethylene of raised temperature resistance), which is a high temperature resistant polyethylene. It is a non-crosslinked polyethylene pipe that can be used for hot water. People have highlighted its non-cross-linking properties, called "high temperature non-crosslinked polyethylene pipes."

Performance characteristics:

1. Good stability and long-term pressure resistance

2, the pipe is easy to bend, convenient construction 3, good impact resistance, high safety

4, anti-aging, long life

5, the processing technology is convenient, the quality is easy to control 6, the waste pipe can be melted, and can be recycled

PPR cold water pipe

It was injection-molded from random copolymerized polypropylene. PP-R was a new generation of pipe material by a gas phase copolymerization process in which the molecular chain of PP of about 5% was randomly and uniformly polymerized (random copolymerization).

Performance characteristics:

1, non-toxic, sanitary

2, insulation and energy saving

3, better heat resistance

4, long service life

5, easy to install

6, materials can be recycled

Application areas:

1. The cold water system of the building

2. Pure water supply system that can be directly consumed

3. Central (concentrated) air conditioning system

4. Industrial piping systems such as conveying or discharging chemical media

PPR hot water pipe

It is generally used as a heating connection pipe, and can also be used as a hot water pipe for water heaters. It is commonly used as a home decoration pipe because of its high temperature resistance and high pressure; PPR is a random copolymer of propylene and ethylene, and PP-R pipe is made of PP-R. The resin is extruded.

Features:

1, health, non-toxic

2, no corrosion

3, wear resistance, no scaling

4, reduce vibration and noise

5, anti-freeze crack

6, anti-condensation, less heat loss

7, anti-corrosion

8, simple installation

9, the cross-sectional area of ​​the pipe is large

10, recyclable

11, long service life

Application areas:

1. Hot and cold drinking water pipe system

2. Industrial fluid delivery system

3. Feeding pipeline system in seaside facilities

4, air conditioning system

5. Agricultural irrigation system

6, the internal piping system of the vehicle

Plastic inspection well

Commonly known as plastic "窨井", it is installed at the intersection of plastic drainage pipes, turning points, pipe diameter or slope change, falling water or at a certain distance on the straight pipe section, which is convenient for regular inspection, cleaning and dredging of drainage pipes. Structure.

Performance characteristics:

1, acid and alkali corrosion resistance, aging, long service life

2, safe and environmentally friendly, sealed and leakproof

3. Uniform settlement and compression resistance

4, construction is convenient and fast

5, efficient drainage

6, light weight, easy to transport and install, reliable performance, strong carrying capacity 7, low overall cost, low maintenance costs, more advantages than traditional inspection wells

8, good sealing performance, anti-leakage

9, saving materials

Application areas:

1. Plastic drainage inspection wells with buried plastic drainage pipes with an outer diameter of not more than 1200mm and a buried depth of not more than 8m in the construction community (residential area, public building area, factory area, etc.), urban and rural municipal, industrial park, old city reconstruction, etc. Design, construction and maintenance.

2. Construction of plastic drainage inspection wells under general soil, soft soil, seasonal frozen soil and collapsible loess soil conditions.

3. The area where the anti-seismic cracking degree is 9 degrees and 9 degrees or less.

4. The ground load of the general lane is 15t according to the total weight of the vehicle; the ground load of the fire lane is designed according to the total weight of the vehicle 30t (the rear wheel pressure is 6t).

5. The groundwater level is designed to be no more than 1.0m below the ground.
