The inner wall of the socket pipe fitting is prone to corrosion, and it must be well inspected and treated. After the corrosion occurs, it is usually expressed as the tube wall of the socket fitting becomes thinner, showing local pits and pits.
The working part of the socket mold, such as the cavity of the socket mold, is designed according to the shape of the product part. In the mold structure design, according to the product geometric model established by the geometric modeling system, the design of the concave mold cavity and the convex mold shape can be completed, and the generated mold profile provides the basis for mold processing.
The connection of socket pipe fittings is not dependent on the construction level, has high efficiency, compact connection structure, lightweight and beautiful appearance, and the wall is embedded without damaging the wall structure. Therefore, in the choice of the connection method, the best choice should be made according to the occasion.
