Stainless steel butt weld cross is a common type of butt welded pipe fittings. It made by steel hot pressing or forging processes. It’s main material is stainless steel, which has excellent corrosion resistance and wear resistance.
According to the different sizes of the ends, butt weld cross can be divided into equal and reducing cross. The connecting ends of equal diameter cross is the same size. The main pipe ends size of the reducing cross is the same. The ends size of the branch pipe is smaller than that of the main pipe.

Butt weld cross is a steel pipe fitting formed by hot pressing or forging. Its connection form is to directly butt weld cross with steel pipe, mainly used for branch connection in pipeline systems. Seamless butt weld cross can achieve 24 inches. Welded cross can achieve 80 inches. Butt weld cross has a wide range of sizes to meet the needs of different types of pipeline systems.
ASME B16.9 Standard
The production standards for stainless steel butt weld tee involve multiple aspects, including material, size, manufacturing process, and quality control. ASME B16.9 is a standard developed by the American Society of Mechanical Engineers (ASME) and is widely recognized internationally as one of the manufacturing standards for stainless steel fittings. It specifies the requirements for the size, material, pressure rating, marking, and inspection of stainless steel butt weld cross.
