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, Must 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 heating pipe during the process of which will be a lot less than expected occurrence of the accident, so it during processing which must pay attention to reduce the occurrence of these accidents.
4, Various indicators for the heating process and the technical requirements are able to do a comprehensive preparation work, thus extending the life of the pipe.
5, The pipe in the heating process which will be very easy to cause oxidative phenomena pipe, so there will be some for the original weight loss, so before the heating must be able to take into account this reason.
