ASME B16.5 is a kind of American standard applied for stainless steel Welding Neck flanges production. It belongs to the standards of pipes and pipe spare parts and short for American Society of Mechanical Engineers (ASME).
ASME B16.5 makes it clear on the requirements of dimension, material, pressure rate and temperature of Welding Neck flanges.
Stainless steel WN flanges are forged from stainless steel materials and have better performance on corrosion resistance and high strength which suits fine to be used in pipe systems with various corrosive environment, such as the chemical, petroleum, natural gas, shipbuilding, and pharmaceutical industries.
WN flanges can not be deformed easily, and are connected with bolts and gaskets in order to seal better.They have corresponding rigid and elastic requirements and a reasonable butt welding thinning transition. The distance between the weld junction and the joint surface is large, preventing the joint surface from being deformed by the welding temperature. It adopts a relatively complex horn-shaped structure, and is suitable for pipelines with large fluctuations under pressure or temperature, or high-temperature, high-pressure, and low-temperature pipelines.
