Description

Technical Field

[0001] The utility model relates to the technical field of metal joints, and more specifically to a metal product joint with high strength. Background Art

[0002] High-strength metal joints are usually made by welding, flange connection or threading. These methods can provide durable and strong connections suitable for a variety of application scenarios.

[0003] Welding is a method of permanently connecting two or more metal parts by heating them to a molten state and applying external force or adding filler materials. It is suitable for environments that need to withstand heavy pressure or high temperature. Threaded connection is a method of tightly connecting two or more metal parts together using a threaded structure. Threaded connection can provide good tensile strength and shear strength, and is suitable for occasions that require frequent disassembly and assembly.

[0004] In liquid pumping applications, welding the metal joint to the equipment makes it impossible to disassemble the joint. When the joint is damaged, it is not convenient to disassemble and maintain. When flange connection is used, multiple bolts need to be disassembled and assembled. The disassembly and assembly process is cumbersome and inefficient. When threaded joints are used, the structural strength of the connection is poor and it is easy to loosen. Utility Model Content
