Rigid PVC pipe for underground sewage and wastewater use PVC resin as the main raw material, adding necessary additives to form a compound, and is produced by extrusion molding.Rigid PVC pipe for underground sewage and wastewater can be divided into elastic sealing ring connection pipe (φ110mm-φ630mm) and adhesive connection pipe (φ110mm-φ200mm) according to different connection methods.
Under the conditions of considering the chemical resistance and heat resistance of the material, pipe for buried sewage and wastewater can also be used as industrial drainage pipe.

Apparence

Bubbles, blisters, obvious impur.ities and irregular corrugations are not allowed on the inner and outer walls of the pipe.Both sides of the pipe should be flat and perpendicular to the axis.The color of the pipe should be uniform.The inner and outer walls of the recessed part of the pipe should be tightly welded and there should be no separation.

Characteristic

1)Excellent flame retardant properties and impact resistance.
2)The inner wall of the product is smooth.
3)The outer wall is corrugated and the corrugated hollow structure makes the product light and high in ring stiffness.

Buried PE pipes for gas

Buried HDPE pipe machine for gas use special polyethylene as raw materials and are extruded products.Safe to use, low leakage rate, good corrosion resistance.Long service life, light weight, high strength, good toughness, convenient construction, wide application and great social benefits.Which is mainly used for natural gas and artificial gas buried gas pipelines.

Apparence

Characteristic

1)The installation process is simple and easy to operate.
2)Anti-corrosion treatment, strong corrosion resistance, long service life buried underground.
3)Strong engineering adaptability.
4)Low investment cost.

PE pipes for water supply

PE material is widely used in the field of water supply pipe manufacturing due to its high strength, corrosion resistance, non-toxicity and other characteristics.Because it does not rust, it is an ideal pipe material to replace ordinary iron water supply pipes.Plastic pipes in my country are developing rapidly and their quality is constantly improving.Among them, polyethylene PE pipes are widely used in building water supply, building drainage, underground drainage pipes, building heating, gas transmission pipes, electrical and telecommunications protection casings, industrial pipes, agricultural pipes, etc. due to their unique advantages.It is mainly used in urban water supply, urban gas supply and farmland irrigation.

Apparence

Characteristic

1)It has excellent corrosion resistance, good hygienic performance and long service life.
2)Unique flexibility and excellent scratch resistance.

PE double-wall corrugated pipe for underground drainage

PE double-wall corrugated pipe for underground drainage is a new type of lightweight pipe made of polyethylene as raw material, processed by extrusion and special molding process. The inner wall is smooth and the outer wall is closed corrugated. It has good performance and high quality. Excellent, suitable for various projects, widely used in municipal sewage drainage, farmland/garden drainage and irrigation, underground drainage outside buildings, ventilation and drainage of mines and tunnels, communication cables, optical cable protective sleeves, various roads and stadium drainage.

Apparence

1)The inner and outer layers of the pipe are uniform in color, and the outer layer is generally black.
2)Bubbles, dents, obvious impurities and irregular corrugations are not allowed on the outer wall of the pipe.
3)The ends of the pipe should be flat, perpendicular to the axis and located in the trough area.

Characteristic

1)Resistant to aging, corrosion and long service life.
2)The inner wall is smooth, the flow moment is small, and there is no scaling.
3)Good sealing and not easy to leak.
4)Shock-resistant and impact-resistant.

PE wound structural wall pipe

This technical product uses high-density polyethylene resin as the main raw material and is produced using a hot winding molding process with excellent weld quality; the unique electrofusion connection technology for sockets and sockets ensures zero leakage at the interface; the pipes and fittings have strong matching capabilities and can be composed Complete, leak-free piping system. It is widely used in buried rainwater and sewage pipe networks, underground pipe galleries, and rainwater and sewage collection systems laid underground in various soil environments and at different depths.

PVC electrical conduit pipe

PVC single line pipe
PVC single line pipe is specially used for load-bearing walls, and the 8mm diameter pipe can minimally modify the load-bearing wall.

PVC corrugated pipe extruder
PVC corrugated pipe is suitable for wiring in small spaces such as ceilings. It has inherent ductility and can be bent freely.

PVC red and blue electrical casing pipe
PVC red and blue electrical bushings have red and blue shunts to distinguish strong and weak currents, which can better standardize circuit installation and maintenance.

PVC trifurcated pipe
The PVC trifurcated pipe is directly divided into partitions on the inner wall of the pipe, stipulating the cable direction and pipe diameter utilization in each partition, thereby conveniently distinguishing lines and avoiding short circuits.

Apparence

The color distinction of home decoration wire pipes in practical applications: red represents strong electricity, blue represents weak electricity, and white represents general electrical casing. It is also easier to distinguish the lines and branch directions of each room.

In recent years, accidents involving plastic pipes have occurred frequently. People always attribute the cause of the accidents to product quality and believe that the quality of the pipes is substandard. Facts have proven that most plastic pipeline accidents are caused by improper design or construction. Construction in strict accordance with specifications is the guarantee for the long-term safe operation of plastic pipeline projects.
