Threaded Flange
Weld-Free Threaded Pipe Flange | For Explosion-Proof Small-Bore Piping
A threaded pipe flange features internal taper threads to screw onto threaded pipes, no welding required for connection. It is the ideal flange threaded type for sites where hot work is forbidden, such as flammable gas and fuel pipelines.
As a reliable flange supplier, Pengrun offers a large selection of flanges made from carbon steel, stainless steel, duplex stainless steel, alloy steel, and special steels. We can produce flanges conforming to various international standards, such as ASME/ANSI, EN, DIN, JIS, GOST, GB, etc.

FAQs
It applies to small-bore low-pressure pipelines where welding is banned, such as gas, fire protection and instrument air systems.
We can produce carbon steel,stainless steel,duplex stainless steel,alloy steel and special steel for threaded flanges.
It connects pipes with two different diameters without extra reducers, simplifying pipeline layout.
No. Threaded joints easily leak under high temperature & vibration; weld neck flange is required for high-pressure critical piping.
