Hole grid square tube is composed of six small square hole perforated pipe, tin grille appear after the tube through a large number of diagnostic, research and consulting, and ultimately developed out. Because tin tube grille lower prices, but also a dedicated fiber optic pipeline, so it became the preferred material for modern communication engineering. Tin grill tube are generally used in burial, can be municipal engineering, highway engineering and bridge engineering, and so on. When we use the tin tube grille, you should know that it is not adjacent to the communication of plastic pipe with heat pipe laying gas pipeline or high-voltage power cables. In laying pipe upvc grille grille tin tube, pipe interface to be staggered. When the tin pipe laying good grill grille tube, should take measures to protect, for example, you can put away a little farther away from the pipe on the warning label to identify or bricks can cover. Whether seven holes Plum Plum large diameter perforated pipe bellows, grid tube advantage that does not affect the surrounding environment or less affected, small construction site, noise. But also deep underground, which is excavating buried incomparable advantages. But the top-tube technology has its drawbacks seven holes grille pipe, construction time is longer, higher construction costs. Currently the world's top tube technology has been developed to a very mature stage, a variety of ways jacking appear. But the plastic grille tube, the original aim, pipe jacking technology principle is the same. It is also in this case, the grid tube application of the domestic market has gradually been supported by a number of construction units, there are more units with a grid tubes used to replace the original solid wall PVC pipe. pvc pipe square hole grille, grille Chifeng tube, provided by Xiong Xiong Thai-Thai-plastic products factory.
