Ⅱ. Product Description

PVC pipe material science name is PVC, is a kind of thermoplastic resin material, it has very good mechanical properties, tensile strength of about 60MPa. In the process of pipe making, adding some auxiliary agent will make PVC pipe have flame-retardant, acid and alkali resistance, wear resistance, as well as important insulation for the threading pipe. It is these excellent characteristics that make PVC pipe occupy a huge market

It is used in indoor normal environment and places with high temperature, dust, vibration and fire hazard. It can also be used in wet places. It is not allowed to be used in extremely humid places with acid, alkali, salt corrosion and explosion risk. The ambient temperature is - 15 ºC to + 40 ºC. The threading pipe has excellent mechanical properties. It has excellent corrosion resistance, high pressure resistance and working pressure over 2.5MPa. The surface of the threading pipe is smooth, the fluid resistance is small, no scaling, and it is not suitable to breed microorganisms. The coefficient of thermal expansion is small and does not shrink. Traditional installation and connection mode. The epoxy plastic coating of the threading pipe can effectively solve the corrosion of water, underground and acid, alkali and salt on the metal pipeline, and the service life can reach more than 50 years.

Ⅲ. Product features

1.  This pvc conduit pipe is made of high-strength special materials and precise craftsmanship, integrating outstanding mechanical properties, excellent corrosion resistance and extremely high structural strength. Its tube structure is scientifically designed, and the material is dense and tough. It not only demonstrates extremely high rigidity and fatigue resistance under daily tensile, bending and torsional loads, but also can resist the erosion of various chemical media and harsh environments for a long time. Particularly prominent is that its unique threaded reinforcement structure, combined with the material's inherent high compressive resistance, endows the product with outstanding pressure-bearing capacity, ensuring its safe and stable operation even under working pressures exceeding 2.5Mpa. It is an ideal choice for dealing with harsh working conditions.

2. This pvc conduit pipe features an exceptionally smooth inner surface that minimizes fluid resistance, significantly enhancing flow efficiency. Its non-porous, inert material effectively prevents scaling and inhibits the adhesion and growth of microorganisms, promoting cleaner fluid transport. Furthermore, the tube exhibits a low coefficient of thermal expansion, ensuring remarkable dimensional stability across varying temperatures without risk of shrinkage or deformation, which guarantees long-term reliability and consistent performance in dynamic thermal environments.

3. The pvc conduit pipe provides a definitive solution to pipeline corrosion, offering robust protection against the degradative effects of water transport, direct burial, and exposure to acids, alkalis, and salts. This high-performance coating forms a seamless, chemically inert barrier that effectively isolates the metal substrate from aggressive environments. As a result, the product delivers exceptional long-term durability and is engineered to achieve a service life exceeding 50 years, ensuring infrastructure integrity with minimal maintenance over its operational lifetime.

Our company's PVC threading pipe production equipment has advanced technology, reasonable structure, reliable performance, simple operation, safe use, high production efficiency, strong extrusion ability, smooth surface of the produced pipes, low fluid resistance, strong circulation ability, no scaling, and is not suitable for breeding microorganisms, and is environmentally friendly and hygienic. The full name of conduit is "insulated electrical conduit for construction", which is a white hard PVC conduit used for anti-corrosion, anti leakage, and wiring purposes. It can be used in various environments and can be used in places with high temperatures, dust, vibrations, and fire hazards. It can also be used in damp places. Do not use in particularly humid, acidic, alkaline, salt corrosive, and explosive areas.

Ⅳ. PVC conduit pipe production line

The core process of the conduit production line is as follows:

The PVC raw materials are preheated and mixed by the 300/600 mixing unit, then enter the SJSZ-65/132 conical twin-screw extruder for melting, plasticizing and extrusion. They are formed into tube blanks through the double-tube mold, and then enter the SZD-4000 double-tube vacuum sizing water tank for cooling and shaping. After that, they are uniformly pulled by the double-tube traction machine and automatically cut to the set length by the cutting machine. Finally, the collection is completed through the double-pipe discharge platform.

Ⅴ. FAQ

What is a plastic pipe extrusion line?

A plastic pipe extrusion line uses machines to melt plastic. These machines shape the melted plastic into pipes. You can make pipes for water and gas. You also make pipes for other jobs. The machines help you make pipes fast. The pipes are always the same size and shape.

Which plastics can you use in pipe extrusion lines?

You can use plastics like PVC, PE, PP, and PET. Each plastic has its own strength and flexibility. Some plastics are tougher than others. Pick the plastic that works best for your project.

How do you keep pipe quality high during production?
