Stainless steel socket weld cross is a widely used pipe connection accessory in pipeline systems. It’s a pipe fitting used in pipeline systems to change the direction of pipelines. The design of the socket enhances the stability of the connection and prevents fluid leakage. The curved part is used to change the direction of the pipeline.

Stainless steel socket weld cross is widely used in pipeline systems of petroleum, chemical, shipping and other industries. It’s corrosion resistance and wear resistance make it outstanding in these fields.

Types of Stainless Steel Socket Weld Cross

Stainless steel socket weld cross can be divided into equal cross and reducing cross according to the ends size. In the piping system, socket weld cross are fittings that change the direction of the piping. ZIZI ENGEERING CO LTD specializes in producing and supplying socket weld cross in accordance with the ASME B16.11 standard. The specifications ranging from 1/8 “to 4” and pressures of Class 3000, 6000, and 9000.

ASTM A182 Stainless Steel Socket Weld Cross

According to ASTM A182 standard, the chemical composition and mechanical properties of stainless steel socket weld cross must meet specific requirements, such as tensile strength, yield strength, elongation, and hardness, all of which must meet the range specified in the standard. They are mainly made of high-quality stainless steel materials, such as 304, 316 and other stainless steel grades. These materials not only have excellent corrosion resistance, but also have good strength and toughness, and can withstand high working pressure and temperature.
