Description

Weld Neck Flange – according to EN 1092-1 Type 11, ISO 7005-1, ASME B16.5.The weld neck flange is designed for butt-welding and for precise alignment with the pipe. Its tapered neck ensures a gradual transfer of stresses, making it the standard choice for high-pressure, high-temperature, vibration, or thermal-cycle applications.

 

Applications

 

Oil & gas installations, water/heating systems, chemical and petrochemical plants, power stations, shipbuilding, machinery and industrial pipeline networks where high mechanical strength and superior sealing are required.

 

Key Advantages

 

  • Excellent pipe alignment and reduced stress concentration in the weld area..

  • Superior performance under high pressure/temperature and cyclic service conditions.

  • Reliable sealing ensured by standardized, precision-machined flange facing.
