I. Product Introduction
PPR full plastic union is a kind of pipe connector made of random copolymer polypropylene (PP - R) as raw material, which is specially designed for the detachable connection of cold and hot water pipe systems. It meets the requirements of GB/T 18742 standard, is produced with 100% imported Borealis raw materials, and has a designed service life of more than 50 years. The product has passed strict hydrostatic test (no leakage under 16.0MPa pressure at 20℃ for 1h) and thermal stability test (no rupture at 110℃ for 8760h), with excellent anti - freezing, anti - smashing and explosion - proof properties. Its temperature resistance range is between - 20℃ and 95℃, and the instantaneous temperature resistance can even reach 110℃.
In terms of specifications, its nominal outer diameter covers 20mm to 63mm, and common specifications include 20, 25, 32, 40, 50 and 63mm, which can meet the connection needs of different pipe systems. There are white, gray and green colors available, which are suitable for the pipe appearance requirements of various use scenarios.
II. Product Composition
The structure of PPR full plastic union mainly includes two plastic interfaces with internal threads and a rotatable sealing ring. The two plastic interfaces with internal threads are the key parts for connecting pipes, which are connected with pipes or related equipment through threads; the rotatable sealing ring plays a sealing role in the process of thread tightening to ensure no leakage at the connection part. Through the synergistic effect of the three, the rapid connection and disassembly of pipes are realized.
III. Product Application
PPR full plastic union has a wide range of application scenarios. In the field of building water supply and drainage, it can be used to connect various cold and hot water pipes to ensure the normal operation of water supply and drainage systems in buildings; in home decoration, it is often used for the connection between equipment such as water heaters, water purifiers and pre - filters and pipes, facilitating the maintenance and replacement of these equipment in the later period; in agricultural irrigation, it can connect irrigation pipes to meet the demand for water resource transportation in agricultural production. In addition, suppliers in Shaoxing, Zhejiang and other places can provide local procurement support to facilitate users in different regions.
IV. Product Advantages
Excellent Performance: Made of high - quality raw materials, it has good temperature resistance and pressure resistance. It has passed a number of strict tests to ensure the safety and stability of long - term use, with a designed service life of more than 50 years.
Convenient Installation: Quick installation can be realized with the help of tools such as a hot melt machine. The installation steps are clear and easy to understand, and the operation is relatively simple. At the same time, compared with the traditional hot melt connection, the full plastic union allows disassembly and maintenance without damaging the pipe, saving time and cost.
Strong Adaptability: The nominal outer diameter covers a wide range, and there are various colors, which can adapt to pipe systems with different specifications and appearance requirements, meeting the use needs of various scenarios.
Environmental Protection and Safety: Some high - end products have passed the GB/T 17219 sanitary safety evaluation, with lead content lower than the national standard, meeting the requirements of drinking water transportation and ensuring the water safety of users.
High Cost - Performance: Considering its performance, service life and installation and maintenance costs, it has high cost - performance and has become the preferred connection method for modern home decoration and small - scale projects.
