Pipe-flange range named in Beicheng’s own company introduction.
Beicheng describes standard and nonstandard flange supply in its company introduction. Begin with the mating pipe and flange drawing, including the required facing and drilling. Confirm the selected material, manufacturing dimensions and inspection scope with the supplier, using the actual requested standard edition rather than treating the introduction’s historical standard references as universal compliance.
