BF Stub End Manufacturers

BF Stub End

The BF Stub End is an essential component within Polyethylene (PE) piping systems, designed to enable reliable flanged connections between PE pipes and dissimilar materials such as metal valves, pumps, or steel pipelines. This fitting represents the PE component of a full flange assembly. One end of the Stub End is specifically engineered for permanent joining with the PE pipe using the Butt Fusion (BF) technique, creating a homogenous weld seam that matches the strength of the pipe itself. The other end features a flat sealing face and a flange neck, intended for mechanical tightening using a metallic backing ring and bolt set. This configuration ensures that the conveyed medium only contacts the inner wall of the PE material, effectively isolating the fluid from potential corrosion or contamination caused by metallic components. The primary advantage of the Butt Fusion Stub End is the flexibility it offers, allowing for system maintenance, equipment replacement, or sectional network testing without permanent alteration to the pipeline integrity. It is a critical component in water treatment facilities, pumping stations, and industrial projects requiring the safe integration of PE networks into existing metal infrastructure, guaranteeing long-term sealing and operational flexibility.
