Butt Fusion Fittings is a kind of fittings used to connect thermoplastic pipes. It heats the connection part of the pipe and the fitting to melt its surface, then butts the pipe and the fitting under a certain pressure and keeps it for a period of time. After cooling, the pipe and the fitting are firmly fused together to form a leak-free integral connection.
Uses: Widely used in various fluid delivery systems, such as water supply and drainage systems, gas delivery systems, chemical pipeline systems, etc. In municipal engineering, it is used to connect urban water supply and drainage pipes; in construction engineering, it is used for the installation of indoor water supply and drainage pipes; in the industrial field, it can be used to transport various liquids and gases, such as petrochemical raw materials, chemicals, natural gas, etc.
Material and Features
Material: Mainly made of the same thermoplastic material as the connected pipe, common materials include polyethylene (PE), polypropylene (PP), etc. These materials have good chemical stability, corrosion resistance and mechanical properties, and can adapt to different working environments. For example, PE butt fusion fittings can resist corrosion from chemicals in water in water supply and drainage systems, and have good flexibility and can adapt to a certain degree of pipe deformation.
Features:
High connection strength: After fusion, the pipe and pipe fittings form a whole, and the connection strength can reach or even exceed the strength of the pipe itself. It can withstand high pressure and external force, and effectively prevent leakage at the pipe joint.
Good corrosion resistance: Since the pipe fittings and pipes are made of the same material, and the thermoplastic material itself has good corrosion resistance, the long-term stable operation of the pipeline system can be guaranteed when conveying corrosive fluids.
Good sealing: The fusion process makes the pipe and pipe fittings seamlessly connected, avoiding the sealing problems that may occur in traditional connection methods (such as flange connection and threaded connection), and ensuring the sealing of fluid transportation.
Convenient and fast construction: With proficiency in technology, the butt fusion operation is relatively simple, does not require complex tools and equipment, and the fusion speed is fast, which can improve construction efficiency.
