PVC drainage pipe and threading pipe production line

PVC pipe line

Introduction of the pipe

1. It has good tensile and compressive strength: but its flexibility is not as good as other plastic pipes.
2. Low fluid resistance: The wall of PVC-U pipe is very smooth and has little resistance to fluid. Its roughness coefficient is only 0.009. Its water delivery capacity is 20% higher than that of cast iron pipes of the same pipe diameter and 40% higher than that of concrete pipes.
3. Excellent corrosion resistance and chemical resistance: PVC-U pipes have excellent acid resistance, alkali resistance, and corrosion resistance, and are not affected by damp water and soil pH. No anti-corrosion treatment is required when laying pipelines.
4. Anti-bite: PVC-U tube is not a source of nutrition, so it will not be corroded by rodents. According to a test conducted by the National Sanitation Foundation in Michigan, rats will not bite PVC-U pipes.
5. It has good water tightness: the installation of PVC-U pipes, regardless of whether it is connected by bonding or rubber ring, has good water tightness.
6. Performance test: curing time, shrinkage, splitting strength, tensile performance, peeling strength, thermal stability, pot life, storage period, release of harmful substances.

Our company has full range of PVC pipe extrusion line, including four cavity pipe extrusion line, double cavity pipe extrusion line and large diameter pipe extrusion line. Our company will also provide basic formula for PVC pipe production, customer can adjust easily based on the formula. We manufacture machines for production of different PVC pipes, including U-PVC, C-PVC, M-PVC, PVC-O pipes, etc.
Our PVC pipe extrusion line can produce from size of minimum 16mm to 1000mm with single layer or multi-layer.

Machine include the following procedure:

raw material preparation

1.  Extruder

1.1 Siemens PLC
1.2 Quality Screw and Barrel
1.3 Air Cooled Ceramic Heater
1.4 High Quality Gearbox and Distribution Box
1.5 Better Cooling of Gearbox1.6 Advanced Vacuum System

1.7 Easy Cable Connection
Both conical twin screw extruder and parallel twin screw extruder can be applied to produce PVC pipe. With latest technology, to lower power and ensure capacity. According to different formula, we provide different screw design to ensure good plasticizing
effect and high capacity.

2. die head

2.1 Moving Device of Die Head
2.2 Die Head Rotary Device
2.3 CNC Processing
2.4 High Quality Material

Extrusion die head apply bracket structure, each material flow channel is placed evenly. Each channel is after heat treatment,
mirror polishing and chroming to ensure material flow smoothly.
Die head is modular design, easy for changing pipe sizes, assembling, dismantle and maintenance. Can produce single layer or multi-layer pipe.

3.Vacuum Tank. 

Vacuum tank is used to shape and cool pipe, so as to reach standard pipe size. We use double-chamber structure. First chamber is
in short length, to ensure very strong cooling and vacuum function. As calibrator is placed in the front of first chamber and pipe
shape is formed mainly by calibrator, this design can ensure quick and better forming and cooling of pipe

3.1 Strong Cooling for Calibrator
3.2 Better Support for Pipe
3.3 Silencer
3.4 Pressure Relief Valve

3.5 Double Loop Pipeline

3.6 Water, Gas Separator

3.7 Full Automatic Water Control

3.8 Centralized Drainage Device

4. Cooling Tank.

4.1 Pipe Clamping Device
4.2 Water Tank Filter
4.3 Quality Spray Nozzle
4.4 Pipe Support Adjusting Device
4.5 Pipe Support Device

5.Haul off unit.

Haul off unit provides sufficient traction force to pull pipe stably. According to different pipe sizes and thickness, our company will customize traction speed, number of claws, effective traction length. To ensure match pipe extrusion speed and forming speed, also avoid deformation of pipe during traction.

5.1 Pipe Clamping Device
5.2 Water Tank Filter
5.3 Quality Spray Nozzle
5.4 Pipe Support Adjusting Device
5.5 Pipe Support Device

6. Cutter.

6.1 Aluminum Clamping Device
6.2 Advanced Hydraulic System
6.3 Dust Collection System
Cutter controlled by Siemens PLC with chamfering function, working together with haul off unit to have precise cutting. Customer can set the length of pipe they want to cut

7.

Full Automatic Belling Machine

7.1 Pipe Cleaning System
7.2 Infrared Heating System

7.3 Central Height Adjustment
To make socket at pipe end which is easy for pipe connection. There are three types of belling type: U type, R type and Square
type. We provide belling machine which can finish belling of pipe on line fully automatic. From minimum size 16mm to maximum size
1000mm, can with multi heating oven and belling station.
