PPR Pipe Tube Production Line Plastic High-Efficiency Electric PPR Pipe Tube Extrusion Machine

PPR Pipe Extrusion Line Plastic Electric Threading UPV/PVC/PPR Pipe Extruding Machine Pipe Making Machine

Product Introduction

PP-R drinking water pipe system is a new type of product commonly used in developed countries in the world today. It uses homogeneous welding technology in cold and hot water transportation projects. Its comprehensive technical performance and economic indicators are far superior to other similar products, especially its excellent hygienic performance. The whole process from production and use to disposal can meet extremely high hygienic and environmental protection requirements. The product has the advantages of heat resistance, pressure resistance, heat preservation and energy saving, long service life and economy.

PPR Pipe Production Process

Raw material + color masterbatch → mixing →vacuum feeding → raw material drying → single-screw extruder → color line extruder → screw type mold → sizing sleeve → spray vacuum calibrating box → spray cooling water tank → jet printer → Caterpillar tractor → finished product testing and packaging.

Problems Encountered in the Production Process of PPR Pipes and Possible Reasons

1. There are scorched marks on the surface of the tube:

The temperature of the fuselage or the head is too high.

The machine head and filter are not cleaned.

There are impurities in the pellets.

The thermal stability of the raw material is poor or the amount of thermal stabilizer is too small.

The temperature control instrument doesn’t work.

2. There are black stripes on the surface of the pipe:

The temperature of the machine head is too high.

The filter is not completely cleaned.

3. The surface of the pipe is dull:

The die temperature is too low or too high.

4. There are wrinkles on the surface of the pipe:

The temperature around the die is not uniform.

Cooling water is too hot.

Towing is too slow.

5. The inner wall of the pipe is rough:

The temperature of the mandrel is low.

Body temperature of machine is too low.

Screw temperature is too high.

6. There are cracks on the inner wall of the pipe:

There are impurities in the material.

The core rod temperature is too low. Body temperature is low.

Towing speed is too fast.

The Characteristics of PPR Pipes

PPR is a random copolymerized polypropylene synthesized by (PP and PE) gas phase method. Its structure is characterized by the random linking of PE molecules in PP molecules, and the molecular weight ranges from 300,000 to 800,000. Pipes produced from PPR are also called random copolymerized polypropylene pipes, which are plastic pipe products developed and applied in the late 1980s and early 1990s. With its own excellent performance and wide application fields, it has occupied a place in the plastic pipe market and is recognized as a green and environmentally friendly product. However, in the market operation in recent years, the analysis of the above-mentioned PPR plastic pipe quality problems has found that many problems have appeared in the PPR pipe market, and these problems have largely restricted the healthy development of PPR pipes.

PPR pipe is one of the most widely used plastic pipes in the world. Due to its excellent hygienic performance, PPR pipes can meet extremely high hygienic and environmental protection requirements in the whole process from production and use to waste and recycling. The products have the advantages of heat resistance, pressure resistance, heat preservation and energy saving, long service life and economy, and are often used in household applications and buildings, including:

1. The cold and hot water system of the building, including the central heating system.

2. Heating systems in buildings, including floors, wall panels and radiant heating systems.

We have been making research and development for special material of PA66GF25 thermal break strip since 2006, we have a deep understanding and rich experience of the relevant industry. We can provide our clients with special material of PA66GF25 thermal break strips of all levels. During these years, we also established a good partnership with many companies is the upstream and downstream industry.

In 2016, we together with factory of mold, extruder and factory of thermal break strips established Zhangjiagang Bangyu Engineering Plastics Co.,Ltd, which is responsible for international import and export business. In 2021, Zhangjiagang Bangyu Engineering Plastics Co.,Ltd was changed ans registered as Suzhou Polywell Engineering Plastics Co.,Ltd. 
The reason why we joined Polywell together with the other two companies is that in this field, the requirements for professionalism are very high. In this field, the company that produce raw materials usually do not research machines and molds, but clients usually need all of them. We found this point, so we joined two other companies established Polywell company together. Polywell can provide a whole set of solution about thermal break strips, including raw material –PA66GF25 granules, extruders, molds, and technical support. This is our biggest advantage.

Strive for customers’ satisfaction and success, service to customers is the principle we’ve always been insisting in the last ten years, to provide our customers with high-quality products and service.

Our domestic sales volume is very stable. We are the main supplier of two listed companies which produce aluminum profile at home, and will obtain the long-term cooperation with them. Otherwise, we also have the long-term cooperation with many small manufactures.

If customers have the need of purchasing other products, we can also provide procurement service.
