Poly pipe plumbing fittings, also known as PE pipe fittings. Its main function is to connect and fix pipes in polyethylene pipe systems to ensure the integrity and functionality of the system.
Role
Polypipe plumbing fittings play a vital role in polyethylene pipe systems. These fittings are not only used to connect pipes but also play the role of fixing and protecting pipes, thereby ensuring the stable operation of the entire system.
There are many types of pipe fittings, including but not limited to flanges, joints, valves, etc., which are selected and used according to specific usage scenarios and needs. The use of these fittings greatly improves the reliability and durability of polyethylene pipe systems, enabling them to adapt to various complex environmental conditions and long-term use requirements.
How to choose Poly pipe plumbing fittings?
When choosing suitable Poly pipe plumbing fittings, the following key factors should be considered:
1. Material and chemical resistance: Polyethylene pipes have good resistance to most domestic and industrial chemicals, but some chemicals such as corrosive oxidants, aromatic hydrocarbons, and halogenated hydrocarbons may cause chemical corrosion too. Therefore, when choosing fittings, you should ensure that the fittings can withstand the chemicals in the expected working environment.
2. Brand and quality: It is more secure to choose pipe fittings from well-known brands, because these brands are usually more formal in terms of product size specifications, appearance design, and performance, and are more reliable to use. The quality of the fittings can be preliminarily judged by observing whether the color and gloss of the fittings are uniform, whether the wall thickness is consistent, and whether there is any pungent odor.
3. Performance indicators: Carefully read the product manual and certificate of conformity to understand the performance indicators of the product. This includes but is not limited to stress cracking resistance, environmental stress cracking resistance, and the ability to resist rapid crack transmission, which are key factors to ensure the safe operation of the pipeline.
4. Adaptability: Poly pipe plumbing fittings should have good flexibility and adaptability to uneven settlement of the pipe base to ensure good working performance in various working environments.
5. Construction and maintenance: Consider the construction performance of accessories, such as lightweight, easy to carry and install, etc. This can reduce the labor intensity of construction workers, improve construction efficiency, and reduce construction costs.
Connection method
1. Hot-melt connection: When the pipes and fittings made of the same thermoplastic plastic are connected to each other, a special Welding Machine is used to heat the surface of the connection part, and the main materials at the connection contact surface are fused to each other, and the connection becomes a whole after cooling. Hot-melt connection includes Butt Fusion Fittings and Socket Fusion Fittings.
2. Electrofusion connection When the same thermoplastic pipes are connected, a special electrofusion fitting is inserted, the HDPE Electrofusion Welding Machine is energized to the electrofusion fitting, and the required heat is generated by the resistance wire pre-buried inside the electrofusion fitting for welding. After cooling, the pipe and the electrofusion fitting are connected as a whole.
Advantages of pipe fittings
Polypipe plumbing fittings are made of high-density polyethylene or medium-density polyethylene and are corrosion-resistant, lightweight, flexible, impact-resistant, non-toxic, and easy to install and maintain. PE pipe fittings are widely used in water supply and drainage, gas transmission, agricultural irrigation, communication and power, etc., providing flexible and safe solutions for pipeline systems. Due to its environmental performance and economy, PE pipe fittings occupy an important position in modern industry and urban construction.
