PVC Pipes (Polyvinyl Chloride pipes)

‌PVC pipe is a kind of plastic pipe made of polyvinyl chloride resin, stabilizer, lubricant, etc., which is extruded by hot pressing. ‌

PVC pipe, full name Polyvinylchlorid, is mainly composed of polyvinyl chloride. Other ingredients are added to enhance its heat resistance, toughness and ductility. In the manufacturing process of this pipe, the outermost layer is usually painted, the middle is polyvinyl chloride resin, and the inner layer is coated with back-coated adhesive. PVC pipe is one of the earliest plastic pipes developed and applied due to its strong corrosion resistance, easy bonding, low price and hard texture.

Production process

1. Material preparation: The main raw material of PVC pipe is polyvinyl chloride resin, and high-quality suspension PVC resin is usually used to ensure the mechanical properties and flame retardancy of the pipe. In addition, appropriate amounts of additives such as tribasic lead sulfate, dibasic lead phosphite, barium stearate, acrylic resin, paraffin and chlorinated polyethylene CPE are added to improve the tensile strength, flame retardancy and processing performance of the pipe.

2. Mixing and preheating: Mix all the raw materials evenly according to the formula ratio and premix them at an appropriate temperature to ensure the uniformity and stability of the raw materials. Then pass the mixed raw materials through the preheating system to reach the temperature range suitable for extrusion.

3. Extrusion molding: Use a single-screw extruder or a twin-screw extruder to extrude the preheated raw materials through the die head mold. The temperature control of the extruder is the key, and the temperature of each section needs to be precisely controlled to ensure that the PVC material can pass through the die smoothly and form the required pipe shape.

4. Cooling and shaping: The extruded pipe is quickly cooled by the cooling device to maintain its shape and dimensional stability. The cooled pipe is further shaped using a shaping device to ensure the uniformity of diameter and wall thickness.

5. Traction and cutting: The shaped pipe is pulled to the specified position by a tractor, and then the pipe is cut into standard length using a cutting machine. It can also be cut into customized lengths according to customer requirements.

6. Printing and inspection: Print general information such as brand logo, specifications, and implementation standards on the pipe. After printing is completed, the finished product is inspected for quality, including appearance, size, mechanical properties, flame retardancy and other indicators to ensure that the product quality meets the standards and customer needs.

Application areas

1. ‌Tap water supply‌: PVC pipes have good corrosion resistance and pressure resistance. They are suitable for the tap water supply system of buildings. They can operate stably for a long time and will not be corroded by chemicals in the water. ‌

2. ‌Drainage system‌: PVC Drainage pipe is also widely used in the drainage system of buildings. It can quickly and effectively discharge wastewater and will not be corroded by chemicals in the wastewater.

3. ‌Agricultural irrigation‌: In the agricultural field, PVC pipes for irrigation are often used as the main pipeline of the irrigation system. They can transport water and withstand a certain water pressure to meet the irrigation needs of farmland.

4. ‌Industrial application‌: PVC pipes are also widely used in various industrial applications, such as chemical transportation in chemical plants, wastewater treatment in industrial production processes, and discharge pipes in industrial mines.

5. ‌Home decoration‌: PVC pipes are also used in home decoration, such as water supply and drainage systems in bathrooms, kitchens, etc. Compared with metal pipes, PVC pipes are not easy to rust and are relatively easy to install and repair.

6. ‌Wire protection‌: PVC conduit is also commonly used in wire pipes to protect wires from the outside environment.

PVC pipe is the perfect solution for municipal water supply and drainage system, urban water supply and drainage. PVC pipes are increasingly popular worldwide for water supply and drainage, industrial and mining water supply, underground fire protective project, farm irrigation project, aquaculture water supply and drainage, etc, because of its advantages:

• Light weight, easy to transport, unload and install.
• Environment friendly: the material is PVC resin, sanitary, pollution- free, clean and cheap.
• Corrosion resistance: PVC pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.
• No leakage: The PVC pipe system is connected by glue connect, rubber ring joint, flange connect methods, which have the good sealing performance when using.
• High mechanical resistance: PVC pipes have good compression resistance, impact resistance and tensile strength.
• Low flow resistance, low wall friction coefficient, which is 0.009, low flow resistance and strong conveying capacity.
• Non-excavation installation: a variety of non-excavation methods can be adopted to facilitate construction and installation.
• Low system cost and low maintenance cost can greatly reduce project costs.
• Long service life: The buried PVC pipe is normally used for 70 years.
• Recyclable, environmentally friendly: PVC materials can be reused, fully in line with the nationally advocated efficient environmental protection concept.
