Cangzhou Shenlong pipeline professional steel surface treatment, for steel shot blasting, spray painting, pickling (steel structure corrosion and rust removal) and other processing methods have a very high level, whether it is steel plate, profile, or other steel structure parts, can be processed, including export steel project packaging, shot blasting spray painting. Heavy anti-corrosion pipe, cement pipe, buried pipe in waterworks, and other services, followed by shelling to tell you about the type and design of anti-corrosion steel pipe

Common water pipelines are generally cast iron pipes or steel pipes. The anti-corrosion treatment methods for the inner wall of this kind of pipeline are generally lined with cement mortar and epoxy coating. Among them, cement mortar is the most traditional pipeline lining, which is still used in many drinking water industries.

Although the anti-corrosion method of lined cement mortar is relatively common, its disadvantages are obvious, such as:

After stress contraction, it is easy to crack, and the surface defects (such as pockmarks, sand holes, empty drums, etc.) are more;

Cement mortar lining will cause the content of dissolved substances to gain, hardness changes, and NH3 precipitation, resulting in the alkalization of water quality;

The instability of water can also affect cement mortar when the CO2 in the water is out of balance amount, concentration reached 7 ㎎ / L, the mortar will lead to damage to sand erosion, which affects water quality.
