PPH Socket
A PPH Socket is a pipe fitting made from Polypropylene Homopolymer (PPH) that is used to join two pipes of the same diameter by inserting them into the socket ends and bonding them using socket fusion (heat welding) to create a strong, leak-proof connection.The PPH Socket is a high-performance pipe fitting designed for secure and leak-proof joining of PPH (Polypropylene Homopolymer) pipes using the socket fusion welding technique. This fitting enables the connection of two plain-end pipes in a straight line, providing a strong and permanent bond ideal for conveying aggressive fluids in corrosive environments.
Made from PPH material, the socket is highly durable, chemically resistant, and suitable for both pressure and non-pressure piping systems. It is widely used in chemical processing, water treatment, and industrial fluid handling systems, where reliability and chemical compatibility are critical.
