Butt welding flange with neck
Butt-welding flanges with necks, referred to as butt-welding flanges, are flanges with tapered necks and with a round pipe transition structure, which are butt-welded to the pipeline.
Its design can effectively reduce stress concentration, provide good sealing and structural strength, and is suitable for high-pressure, high-temperature or low-temperature working conditions.
As the weld opening is far away from the sealing surface, deformation in the heat affected zone of the weld can be avoided to ensure sealing reliability.

Advantages of butt-welding flanges
- Excellent sealing properties
Due to the welding connection, butt-welding stainless steel flanges can maintain good sealing performance during the working process, effectively preventing fluid leakage and ensuring the safety of the piping system.
- High-strength pressure resistance
Butt-welding stainless steel flanges are tightly connected to the pipeline through welding and can withstand high internal and external pressures, suitable for high-pressure, high-temperature working environments to meet the stringent industrial requirements.
- High corrosion resistance
The excellent corrosion resistance of the stainless steel material extends the service life of the flange.
- Easy to install
Butt-welding flanges are simple to install, connected by welding, without the need for complex tools and equipment, facilitating mass production and rapid installation.
