This is a modern long-distance pipeline transportation industry, the most basic transport pipeline, thick-walled seamless steel pipe because the wall thicker in the field has a strong anti-collision, corrosion-resistant nature, in the long-distance oil, and natural gas transport has been an irreplaceable role, although the field of modern pipeline transportation are in use, but the installation is always a big problem.
Pipeline there are joint place, here is the focus of the installation, such as pipe wall with thick, almost no management way of some environmental problems, usually directly after digging a hole big enough to accommodate pipe, directly put into the pipeline, but where the joint will note that this is the place where the test technology of the workers.
Commonly used in the production of thick wall seamless steel tube has been ready to joint work, each type of pipe has its own unique bolt, if the use of forced some pipeline model does not match, will not only affect the pipe, at the same time in the process of transportation may be compromised.
