Process of pipe cap manufacturer  

Pipe cap manufacturers introduce the production process of pipe cap: the material of pipe cap pipe fittings is generally divided into steel plate production process: steel plate, cutting, heat treatment, processing groove, finished products, quality inspection, qualified products, packaging, transportation  

Non-destructive testing (NDT) NDT is an important procedure for checking possible defects in the processing of materials and pipe fittings.  Nondestructive testing requirements are stipulated in most pipe fitting product standards, but the requirements are not consistent.  In addition to NDT to meet the requirements of product standards and orders, some manufacturers with strict quality control also make NDT requirements according to the materials, processing technology and internal quality control regulations to ensure the quality of ex-factory products.  The qualification grade of pipe fittings in the actual work should be determined according to the explicit provisions of the order requirements or standards.  

The outer protection of the pipe cap on the outer protection of carbon steel, alloy steel pipe fittings generally choose the method of painting, the method of passivation after pickling for stainless steel (for all the outer cutting of stainless steel pipe fittings, can not be passivation treatment).  The primary intention of pipe fittings exterior protection is anticorrosion, which also achieves the function of beautiful appearance of products.  Generally, the ordering party puts forward specific requirements for the appearance protection, and the manufacturing factory completes the appearance protection of pipe fittings according to the requirements of the ordering party.  Marking marking is an integral part of the product and is the basis for completing traceability requirements.  In general, there are rules for marking contents and methods in product specifications.  The marking content of pipe fittings generally includes the manufacturer's mark or title, data grade, standard and other contents required by the order.  The marking method includes different marking, such as stamping, carving, electroetching, etc.;  Various signs, such as printing, labels, etc.  In addition to the above conventional production process, in order to control the quality of the original data, the factory should also complete the inspection of the original and auxiliary data to ensure that the data used is correct;  In order to satisfy the special requirements of the order or data, inspection and test such as metallographic structure, intergranular corrosion, ferritic, etc. should be carried out to ensure the quality of the products provided.
