Carbon steel socket cap
carbon steel socket cap is an important branch of the high-pressure pipe fittings. It plays an important role and value in the mechanical, chemical, petroleum, construction and other industries. The socket pipe fittings have different varieties and functions, and different types of socket pipes Pieces play different roles, and their scope of use and environment of use are also different.
Socket welding pipe cap also known as high pressure pipe cap, forging steel pipe cap, nominal size: 1/4 "- 5", DN20-DN200, applicable medium: water, steam, oil etc. The socket pipe cap quality directly affects the operation of the pressure vessel. For the forming of tailor-welded before and after the split forming butterfly head welding tests, it is very important.
1,Before forming welding: ensure welding quality (surface testing, pay attention to the welding current, welding method, etc.), the best ray detection. Internal grinding with the base level before stamping. Ray detection after forming.
2,After the split forming welding: guarantee welding quality (surface testing, pay attention to the welding current, welding method, etc.), radiographic testing.

The socket tube is a small-sized product. A small forged hydraulic press can be used to produce a qualified blank by repeated forging. The blank size and machining allowance of the socket fittings are selected by the R&D personnel according to the actual situation and design.
Please refer to the relevant standards. The parting surface of the socket tube is to be added with a certain draft angle so that the socket tube can be smoothly taken out from the mold cavity after forming. There are many factors affecting the draft design, and the combination of automatic design and interactive selection can be used to determine the draft slope value. Usually, the outer slope is 8 degrees and the inner slope is 12 degrees. The working part of the socket fitting mold is designed according to the shape of the product part. In the design of the mold structure, according to the geometric model of the product established by the geometric modeling system, the design of the concave mold cavity and the convex shape can be completed, and the generated mold surface provides the basis for the processing of the mold. In addition to the design of the shape of the working part, the shape design of the mold part also uses geometric modeling technology.
