The difference between elbow and bend in manufacturing process

The essential difference between the elbow and the bend is mainly the difference between the “head” and the “pipe”. In addition, there are also great differences in the manufacturing process.

Elbow is a kind of connection fittings commonly used in plumbing installations. It is used to connect the bends of pipes to change the direction of the pipes. It is used to connect two pipes with the same nominal diameter or different diameters to make the pipe turn at 90 °, 45 °, 180 °and various degrees. The following briefly introduces the differences in the manufacturing process between elbows and bends:

5D ASTM A106 Grade B hot induction bends

1.The elbow is relatively short compared to bend. R = 1 to 2 is the elbow, and the bigger multiple is called bend.

2.The cold bend can be made by using a straight pipe bending machine,which can be finished once without secondary corrosion protection.However, the elbow should be customized by the manufacturer,be anticorrosive,and have a long order cycle.

3.The price of elbow is higher than that of bend, but the cost performance is much higher than that of bend. The bend without anti-corrosion treatment is easy to damage, but because of its cheap price, it is used in some projects that are not very demanding. So when the performance and price of the elbow and bend are different, you need to pay attention.
