Carbon steel elbow in the market price transparent
Butt welding elbow according to its curvature radius, can be divided into long radius butt welding elbow and short radius butt welding elbow. The curvature radius of the long radius butt welding elbow is equal to 1.5 times the outer diameter of the pipe, i.e., R=1.5D. The curvature radius of the butt welding elbow with short radius is equal to the outer diameter of the pipe, namely R=1D. Where D is the diameter of butt welding elbow and R is the radius of curvature. In the absence of special instructions, 1.5D elbows are generally selected.
If divided according to the pressure level, there are about 17 kinds of pipe standards, which are the same as those of the United States, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are commonly used.
According to the Angle of the elbow, there are 45 degrees butt welding elbow, 90 degrees butt welding elbow and 180 degrees butt welding elbow and other different angles of the elbow.
Materials: carbon steel, alloy steel and stainless steel.
Large caliber butt welding elbow according to the Angle of the elbow, there are 45° butt welding elbow, 90° butt welding elbow and 180° butt welding elbow, other special Angle elbow can be processed according to the customer's drawing. The general materials of large-bore butt welded pipe fittings include carbon steel, alloy steel and stainless steel. Elbow according to its curvature radius, can be divided into long radius butt welding elbow and short radius butt welding elbow. The curvature radius of the long radius butt welding elbow is equal to 1.5 times the outer diameter of the pipe, i.e., R=1.5D. The curvature radius of the butt welding elbow with short radius is equal to the outer diameter of the pipe, namely R=1D. Where D is the diameter of butt welding elbow, R is the radius of curvature; If divided according to the pressure level, there are about 17 kinds of pipe standards, which are the same as those of the United States, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are commonly used;
