For the welded pipe, the quality of the weld is to determine the performance of the main factors that are seen in the winter heating water pipe or pipes are to be frozen explosion things, in general, where the burst are generally weld.
The seamless tube Longitudinal resistance and scope of its application. Longitudinal if you want to develop rapidly, it is important to achieve a seamless way, through the seamless pipe, the pipe manufacturer can not only improve the efficiency, but also can greatly jiangdu costs of users, so it is economically viable. Therefore, seamless pipes of its development is an inevitable trend. In water engineering, chemical industry, agriculture irrigation, urban construction, Longitudinal has widely used, but also can be transported as a liquid water supply, drainage, as a gas, vapor and other gases in transport, as docks, roads, building structure tube. In short, Longitudinal activities in modern life, have been widely used, is indispensable.
