How should the blasting pipe be applied :
The sand blasting pipe is manufactured by the zinc-iron alloy process. It lies in the fact that the production line grooves and the grooves are perforated directly without any carry-out or overflow of the solution.
Each step of the production process consists of a circulation system, and it also uses the production process of periodic discharge, which is not recycled after being passivated, and is not produced.
In order to improve the corrosion resistance of the sand blasting pipe, the thickness of the hot-dip galvanizing layer is low, the cost of galvanizing is low, and the surface is not very smooth. In order to prevent corrosion, some need to be aluminized.
Most of the old houses used sandblasting pipes. Now the iron pipes for gas and heating are also sandblasting pipes. Sandblasting pipes are used as water pipes. After several years of use, a large amount of rust is generated in the pipes, and the yellow water flowing out not only pollutes Sanitary ware, and mixed with bacteria growing on the non-smooth inner wall, the rust caused the heavy metal content in the water to be too high, which seriously endangered human health.
