With the further development of modern science and technology, the information technology industry is further improved, and various communication networks are located all over the world. Telephone, mobile phone, the internet is connected by countries all over the world.
The transmission of this information requires communication lines, which are the facilities for the exchange of these communication lines. In order to ensure the normal communication of optical cable information, is to use steel pipe to transport optical cable, on the one hand to ensure the smooth optical cable, on the other hand, so that the optical cable in the use of the process to avoid damage Steel pipe produced by steel pipe Factory, the quality must be excellent. Because it is buried in the ground, the rain cannot be allowed to corrode the steel pipe, lest the fiber optic cable be damaged. Then there is the road construction, digging machine encountered communication lines. The quality of the steel pipe does not pass, it will destroy the optical cable, so that communication is blocked. Affect the normal dissemination of information, causing heavy losses to the state, so that the economic interests of the country are infringed.
Such a loss is too great. The quality inspection Department of the steel Pipe factory shoulders a great responsibility, must be meticulous and careful, in order to produce high-quality steel pipe, used for underground optical cable channels, to ensure the normal operation of communications.
