Plastic compression fittings refer to pipe fittings made of plastic materials. These pipe fittings are usually used to connect or form plastic pipe systems. Plastic pipe fittings are favored in pipeline engineering because of their lightweight, hygiene and safety, low water flow resistance, energy saving, metal saving, improvement of living environment, long service life, and easy installation. Plastic compression fittings have a wide range of applications, including but not limited to compressed air pipes, mining pipes, plastic fire-fighting pipe fittings, etc. These pipe fittings usually have good fire resistance, corrosion resistance, impact resistance, and pressure resistance. At the same time, they are light in weight and easy to install, and the pipe wall is flat and smooth. It is not easy to generate friction resistance and adhesion when conveying fluids. They have suitable toughness, ensuring their reliability and durability in various environments.
The function of Plastic compression fitting
Plastic compression fittings include various types, such as Electrofusion Fittings, hot melt fittings (butt, socket, saddle), and short pipe center parts (elbows, equal tees, reducing tees, end caps, flange ends), etc. These fittings are made by injection molding and are widely used in various plastic piping systems. Their functions are mainly reflected in the following aspects:
1. Connection and fixation: Plastic compression fittings can effectively connect and fix plastic pipes to ensure the integrity and stability of the pipe system.
2. Enhanced durability: By using plastic pipe fittings, the durability of plastic pipes can be enhanced to prevent pipes from rupturing or leakage due to external pressure or internal fluid pressure.
3. Improved safety: These pipe fittings can improve the safety of the pipe system and reduce the risk of safety accidents caused by loose or damaged pipe connections.
4. Easy to repair and replace: Pipe systems connected with plastic compression fittings are easier to repair and replace because the design of the fittings makes it easier to disassemble and replace the pipes.
Production process
1. Prepare raw materials
The raw materials of plastic pipe fittings are mainly plastic resins such as PE, PP, and PVC. In addition, additives such as masterbatch need to be added. Before production, these raw materials need to be strictly inspected and tested to ensure that the quality of the raw materials meets the standards and meets the production requirements.
2. Pipe fitting processing
When processing plastic pipe fittings, the pipes must first be cut into sections of different lengths according to the design requirements, and then injection molded. This step requires the use of an injection molding machine to inject the plastic into a pre-designed mold to form pipe fittings of various shapes.
3. Quality inspection
After production, the entire production process needs to be inspected to ensure product quality. It mainly includes inspections of appearance quality, working pressure, sealing, etc. Only products that have passed quality inspections can be shipped.
Advantages and Features
1. Lightweight: The lightweight characteristics of Plastic compression fittings make it more convenient during transportation and installation. Compared with traditional metal pipe fittings, plastic pipe fittings are lighter, which reduces transportation costs, and no large equipment or complex tools are required during installation, which reduces the difficulty of construction.
2. Corrosion resistance: Plastic pipe fittings have good corrosion resistance and can resist chemical corrosion.
3. Easy installation: The installation of plastic pipe fittings is relatively simple and quick, which helps to speed up the progress of the project.
4. Economical: The cost of Plastic compression fittings is relatively low, especially when mass-produced, its cost advantage is more obvious. In addition, the recyclability of plastic pipe fittings also reduces environmental impact costs.
5. Environmental protection: Some plastic pipe fittings will not produce substances harmful to the human body and the environment during recycling and remanufacturing, and are green and environmentally friendly materials.
6. Longer service life: The service life of plastic pipes can reach 50 years or more, which reduces the frequency of replacement and maintenance, thereby reducing long-term costs.
