| Abstract: | To substitute inner hole welding construction for traditional end surface welding construction, is the fundamental method for raising the stabilities of anti-sires cracking and crevice corrosionproof for the welding joint has the characteristics of high reliablity,no crevice,convenient to examing welding joint, easily assembly, and short manufactory period. And it has the wide applied prospect in petrochemical industry. |
