GB Standard Weld Neck Flange

Feature: The long neck of this flange allows full penetration welding with the pipe. The weld joint is smooth and tight, minimizing gaps where media could accumulate or leak, thus improving sealing performance—critical for corrosive or toxic media.

Application: Ideal for connecting chemical reaction kettles to pipelines. Reaction kettles often handle corrosive liquids (e.g., sulfuric acid, nitric acid) or toxic gases; the flange’s tight welds prevent media leakage, protecting the environment and personnel safety.
