Product description
The connection form of stainless steel 180 degree pipe fitting is butt welding elbow and steel pipe directly. According to its curvature radius, butt welding 180 degree stainless steel pipe elbow can be divided into long radius and short radius. Pressure grade is divided into about 17 types, which are the same as American pipe standard. The most commonly used are STD , SCH10, and SCH40. According to material, they are carbon steel, alloy steel and stainless steel.
