Notes for heating welded pipe
Pipe machining process requires strict, in which the hot rolling process is a very important step, in which to introduce Caution heating pipe in the process. 1, The pipe must be able to feed one of those metal properties were a good understanding before performing hot rolling, when the deforming force is relatively low during the hot-rolled steel is very easy. But for pipe materials which contain some or ingots, so prior to hot rolling must be able to be on one of those ingot some eliminated, making it organizational capacity and resilience are able to get some improvement, and also the pipe during the hot rolling process which also would have been greatly protected. 2, Pay attention to each pipe section has a temperature uniformity in all directions during the hot rolling process, so that the pipe can better meet the requirements of various technological aspects in later. In addition, the heating pipe will affect a very important reason for the life of the pipe. 3, The h...
