Polyethylene (PE) gas and water fittings are fittings made of polyethylene material used for the transportation, distribution and control of gas and water in pipelines. These fittings are widely preferred, especially in underground infrastructure projects, drinking water systems and gas distribution networks. Polyethylene is an ideal material choice for these applications due to its durability, flexibility and resistance to chemicals. Polyethylene fittings include various types such as elbows, tees, couplings, adapters, valves and reducers. These fittings are usually used by welding them to each other or to polyethylene pipes by methods such as electrofusion or butt fusion. The use of polyethylene gas and water fittings varies according to engineering requirements and project specifications.
Polyethylene Gas and Water Fitting Types
Polyethylene gas and water fittings are available in various types and sizes. This diversity is designed to meet different needs and applications. Below is information on the most common types of polyethylene gas and water fittings and their intended use:
- Elbows: Used to change the direction of pipelines. They are usually located at different angles, such as 22.5°, 45° and 90°.
- Tees (T-Pieces): Used to branch from a main pipeline to a branch line. Tees are used when pipelines need to be joined or split.
- Couplings (Joining Parts): Used to connect two pieces of pipe together. Couplings can be used to extend pipelines or replace damaged sections.
- Adapters: Used to connect pipes of different diameters or types. Adapters can also be used to join pipe systems made of different materials.
- Valves Used to control, start or stop the flow. Different types of valves are available, such as ball valves, butterfly valves and check valves.
- Reducers: Used to reduce or increase the pipe diameter. This is necessary to adjust the flow rate or pressure in different sections of the pipeline.
- Termination Caps: Used to close the open ends of pipelines. These covers can be used temporarily while the system is being tested or during maintenance/repair.
- Electrofusion Fittings: Designed for welding pipes using electric current. Electrofusion is preferred in applications requiring high strength and sealing, especially for gas lines.
- Mechanical Fittings: Fittings that do not require welding and are mechanically connected to pipes. Easy to assemble and disassemble, used for emergency repairs or temporary connections.
These variants provide flexibility and efficiency during the installation and maintenance of polyethylene pipe systems. Selecting the right type of fitting according to the project needs ensures long life and safety of the system.
Areas of Use
