The Characteristics of Weld Neck Flange

  The Weld Neck Flange is the flange of the inner hole was machined into the pipe thread processing, and with the supporting pipe to achieve the connection, is a Weld Neck Flange. It is compared with the welding flange or welded neck flange, Weld Neck Flange is easy installation , some places can not be allowed welding of the pipeline. DN80 PN16  6 Inch  Forged Stainless Steel Weld Neck Flange have sufficient strength, but not easy to weld, or welding performance is not good, can also choose Weld Neck Flange. However, in the pipeline temperature changes rapidly or the temperature is higher than 260 ℃ below -45 ℃ conditions, it is recommended not to use Weld Neck Flange, so as to avoid leakage.

  Weld Neck Flange with a low height, the Weld Neck Flange stiffness, load capacity has increased. Compared with the Weld Neck Flange, welding workload, welding consumes high, can not withstand high temperature and pressure and repeated bending and temperature fluctuations, but the site installation is more convenient and popular can be omitted welding seam rubbing injury process.
