What is a galvanized steel pipe coupling used for?
It is used to connect two pipes with the same diameter in threaded piping systems.
It ensures a secure and leak-free connection in water, gas, and industrial pipelines.
What thread standards are available?
We offer NPT and BSP thread standards.
Custom thread types can also be provided based on project requirements.
Can you provide OEM galvanized steel pipe coupling?
Yes, we support full OEM service.
We can customize size, marking, packaging, and surface treatment according to your specifications.
Built tough. Coated to last. Threaded to connect.
We manufacture threaded couplings that connect two pipes or pipe nipples in a straight line.
Our 304 stainless steel couplings are known for corrosion resistance, durability, and strength. They perform well in environments with moisture, chemicals, or temperature changes, where carbon steel may fail.
In threaded piping systems, couplings are used with pipe nipples, elbows, tees, and valves. This versatility makes them essential for industrial installations, maintenance, and equipment assembly.
As a pipe fitting manufacturer, we produce stainless steel pipes and fittings that meet common standards and provide accurate NPT or BSP threads.
