2026-01-12Main Functions and Manufacturing Methods of Weld Neck FlangeWeld Neck Flange can greatly save space and reduce weight, and it can also ensure no leakage at the joint with excellent sealing performance. The reduction in the size of Weld Neck Flange is attributed to the reduced diameter of the sealing element, which in turn decreases the cross-sectional area of the sealing surface. In addition, the flange gasket has been replaced with a sealing ring to ensure the perfect fit between the sealing faces.View Details + -
2026-01-09Briefly describe the main design of stainless steel flangesStainless steel flanges will not corrode, pitting, rust, and are not easily worn. Stainless steel is one of the high-strength materials used in construction. Because stainless steel has good corrosion resistance, stainless steel flanges can ensure the integrity of structural components in engineering design.View Details + -
