High speed PVC pipe extrusion line manufacturer

PVC pipes are widely used in the industry, and PVC pipes are also very popular in the market. There are also many types of PVC pipes, which makes consumers unclear when purchasing. The following will introduce the classification of PVC pipes.
PVC pipes are divided into PVC water supply pipes, PVC drainage pipes, PVC threading pipes, and PVC irrigation pipes. According to the material, it is divided into: PVC-U (unplasticized PVC), C-PVC (chlorinated PVC), PVC-O (molecularly oriented PVC), high impact PVC (PVC-HI).
Besides sharing many of the same properties (such as safety, durability, sustainability, and recyclability), each type of PVC has its own advantages for different applications.
UPVC, also known as rigid PVC, is an amorphous thermoplastic resin composed of vinyl chloride monomers and certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to the use of additives, the method of mixing with other resins is also adopted, which makes it have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and so on. UPVC has high melt viscosity and poor fluidity. Even if the injection pressure and melt temperature are increased, the flowability will not change much. In addition, the molding temperature of this resin is very close to the thermal decomposition temperature, and the temperature range that can be molded is very narrow, making it a difficult material to mold.
As a new type of pipe, CPVC pipe has excellent corrosion resistance. In recent years, it has been widely used in steel, metallurgy, petroleum, chemical, fertilizer, dye, pharmaceutical, electric power, environmental protection, sewage treatment and other industries. It is an ideal substitute for metal anti-corrosion materials. The service temperature of CPVC pipes and fittings can reach 93-100℃, which is 30-40℃ higher than PVC. At the same time, it can improve the chemical resistance and corrosion resistance of PVC. It is resistant to chemical attack by strong acids, alkalis, salts, fatty acid salts and oxidants and halogens.
Since the PVC-O pipe is to stretch the originally formed PVC-U pipe axially and radially, the wall thickness of the pipe is relatively thin. Compared with the wall thickness of PVC-O and PVC-U, the wall thickness of PVC-O water supply pipe can be reduced by 35%-40% than that of PVC-U water supply pipe, which greatly saves materials and reduces costs.
PVC-HI refers to high impact PVC. PVC-HI grades are obtained by adding to PVC-U an impact modifier that increases the resistance of the pipe to external impacts.

PVC pipe extrusion line is used to produce PVC pipe with diameter from 16 up to 800mm, which is used for electric conduit, building drainage, sewagepipe, water supply pipe, well casing pipe, agricultural irrigation pipe and so on.

PVC pipe extrusion line mainly composed by: material feeder, conical twin screw extruder, mould, vacuum calibration tank, haul off machine, cutting machine, stacker, and pipe belling machine. By changing dorn or mould lip, it can produce several diameter or wall thickness on same machine.

Main features of PVC pipe extrusion line: 

1. The screw is suitable for high calcium and low calcium and foaming.
2. The vacuum box can be used as a negative pressure vacuum to increase the output, spray (6m one true two water, motor 37/45kw for 65/132 extruder, 55/75kw for 80/156 extruder), plus a spray box for large pipes, small Pipes are normally not required. Made of stainless steel, the sprinkler head is a new material (high pressure and good atomization effect) high pressure sprinkler head.
3. Traction hard tooth surface, K series gearbox (or use servo motor), independent drive motor, stable and durable (big pipes are driven independently, small pipes are integrated)
4. The large pipe of the cutting machine is circularly cut (it is recommended that the circularcutting has low failure rate, strong stability, and easy maintenance), or no dust cutting machine((for small diameter pipes).). The cutting machine is equipped with a chamfering device.

5. The internal stepped structure of vacuum forming and cooling is convenient for operation when producing pipes of different diameters.
6. Vacuum tank water level control Liquid level control, automatic drainage. (The angle seat valve is automatically opened when the liquid level is full, and the drainage is also automatically drained) The solenoid valve controls the angle seat valve.
