Stainless steel threaded cross is a commonly used high-pressure pipe fitting in industrial pipelines. They are mainly used to connect pipeline systems and change fluid direction. It is made of stainless steel material. Stainless steel has excellent corrosion resistance and durability.
Threaded cross adopts a threaded form to connect the pipeline, which has the features of easy installation and good sealing. Stainless steel threaded cross is widely used in pipeline systems in industries.
Scope of Stainless Steel Threaded Cross
Stainless steel threaded cross under ASME B16.11 standard. They are commonly used for connecting small-diameter high-pressure pipelines, with sizes ranging from 1/8 inch to 4 inches (DN6-DN100). The pressure levels include 2000LB, 3000LB, and 6000LB. These factors collectively determine the detailed dimensions and performance parameters of threaded cross.
