Why use pipe couplings

Pipe joints play a vital role in piping systems, used to connect different pipes, enabling multiple pipes to be connected together to form a complete piping system for fluid or gas transmission, diversion, merging and control. With flexibility and adjustability, it makes the pipeline system adaptable to different layouts and demands. Meanwhile, the specific sealing and safety of pipe joints are crucial to the operation of piping systems. Through the use of sealing materials, sealing structures and fastening devices, it ensures that the pipe joints have good sealing performance, prevents the leakage and contamination of fluids or gases, and ensures the safety of the system and the protection of the environment. When it is necessary to repair, replace or clean the piping system, the joints can be quickly disassembled, reducing time and production costs. Fittings have unified standards and specifications, ensuring interchangeability and compatibility of fitting components in different regions, promoting the convenience and consistency of engineering design and construction. They can compensate for thermal expansion and cold contraction caused by temperature changes, as well as pipe displacement, reduce vibration and noise, protect piping systems, and play an indispensable role in piping systems. Haisheng offers a wide range of pipe fittings in various forms and models to meet the needs in different industries and workplaces.

Selection of materials for joints

There are various types of materials for pipe joints, and different industries and workplaces should choose the appropriate materials.Stainless steel: corrosion resistance and durability, applicable to a variety of environments.Carbon steel: high strength, but poor corrosion resistance, usually used for the transmission of non-corrosive media.Copper: thermal conductivity and corrosion resistance, commonly used in water supply systems and heating systems.Aluminum-plastic composite materials: lightweight, durable and easy to construct, suitable for use in home decoration.PPR: non-toxic, lightweight, pressure-resistant, corrosion-resistant, suitable for hot and cold water piping systems.Rubber: good vibration damping and expansion performance, suitable for scenes that need to absorb vibration and thermal expansion.UPVC: commonly used in sewage pipes.Cast steel: high strength, good pressure resistance, suitable for high-pressure piping systems. Malleable cast iron: commonly used for making threaded live fittings, with good corrosion resistance and mechanical properties.
