fundamental processes carbon steel bw lr 90 deg elbow is: First welding a polygonal cross-sectional polygonal ring shell or both ends blockade polygonal fan shells, washed over the internal pressure of the media, applying less pressure, including pressure effect under cross-section polygon gradually become round, eventually becoming a circular ring shells. Based on demand, a circular ring shells can cut four 90 60 elbow or 6 elbow bends or other specifications, the process for the manufacture of elbow bend diameter and an inner diameter greater than 1.5 than any specifications large elbow, is currently manufacturing large carbon steel bw lr 90 ideal way to elbow in deg.

The carbon steel bw lr 90 deg elbow main advantages of the manufacturing process table now following aspects:

(1) without shell as raw materials, saving pipe equipment and tooling costs, and the large diameter and wall thickness can be obtained wanton relatively thin carbon steel bw lr 90 deg elbow.

(2) the blank is flat or developable surface, thus cutting simple, easy to ensure accuracy, assembly welding lunch.

(3) Due to the above two reasons, it is possible to shorten the manufacturing cycle, consumption cost is greatly reduced. Because they do not demand any special equipment, particularly suitable for on-site processing of large carbon steel bw lr 90 deg elbow.
