Product & Selection Description
The PPH external thread butt welding direct is a critical transition fitting in PPH piping systems, used to create a reliable connection between a PPH pipe and a metal component with external threads.
Core Material Advantage: The Beta-(β) crystalline homopolymeric polypropylene used offers superior chemical resistance and the highest pressure resistance (MRS10) among all polypropylene pipe materials. It also provides notable low-temperature impact strength, ensuring high system safety and a long service life.
Application Scenarios: This fitting is widely used in piping systems for industries such as chemical, wastewater treatment, and power. It is particularly suited for applications requiring a connection between a PPH pipeline and metal valves, instruments, or other equipment ports.
