A234 WPB Carbon Steel Seamless Elbow

90 degree elbow is a common connection pipe fitting in pipeline installation, used to connect the pipe Bend. Connect two pipes of the same nominal diameter to make a 90 degree turn. According to the Angle, there are 45° and 90°180° three most commonly used, in addition, according to the engineering needs also include 60° and other abnormal Angle elbow.

The connection with the pipe is: direct welding (the most commonly used way) flange connection, thread connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, casting elbow

90-degree elbows are divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, ppc, etc.

90 degrees elbow can be divided into pushing, pressing, forging, casting, etc.

90 degrees elbow can be divided into national standard, electrical standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on. 

Long radius elbow A bend is a pipe whose radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D. Short radius elbow means that its radius of curvature is equal to the outside diameter of the pipe, that is, R=D. Where D is the diameter of the elbow and R is the radius of curvature. According to the pressure grade, there are about 17 kinds of pipes, which are the same with the American pipe standards, 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.

We should pay attention to the late maintenance of elbow. Long-term storage elbow, should be checked regularly, often on the exposed processing surface must be kept clean, remove dirt, neatly stored in a ventilated and dry place, strictly prohibited pile or open storage. Long-term storage elbow elbow, should be checked regularly, often on the exposed processing surface must be kept clean, remove dirt, neatly stored in a ventilated and dry place, strictly prohibited pile or open storage. Attention should be paid to the tightness of the elbow during installation to prevent leakage and affect the normal operation of the pipeline. Ball valves, globe valves and gate valves of elbow are only fully opened or fully closed, and are not allowed to be used for regulating flow, so as to avoid erosion of sealing surface and accelerated wear.
