The difference between elbow and elbow The basic difference between elbow and elbow is that the elbow is shorter than the elbow. R=1 times to 2 times is the elbow, and then the large multiple is called elbow. In the production process, the cold bending pipe can be bent by ready-made straight pipe bending machine, and the one-time completion does not need two anticorrosion. But the elbow to manufacturers custom, to do anti-corrosion, ordering cycle is long. The elbow price is higher than the elbow, but the cost performance is much higher than the elbow, no anti-corrosion treatment of the elbow is easy to damage is well-known, but because of its cheap price in some of the requirements are not very high engineering use is very much. Elbow to manufacturers custom, anti-corrosion, long ordering cycle. Cold benders can be bent using ready-made straight pipe benders. It's done in one go without a second anticorrosion. There is a petroleum standard for the construction technology of cold bend pipe, and there is an enterprise standard for the west-east gas transmission. But the open area with elbow elbow can be, only considering the cost, elbow need hot simmer, elbow cold bend can, of course, elbow cost is high. Sometimes a bend must be used in the narrow section, such as stone channel, because the radius of curvature of the bend is small, generally 6D, and the bend is 40D.
