Several Methods to Control the Corrosion of SSAW Steel Pipe

According to SSAW steel pipe corrosion mechanism, and it has so far proposed a variety of protective measures, such protective measures basically be divided into the following types:
1. For the environment among the harmful substances from outside to inside gradually invasive characteristics, including permeability to adopt a series of technical control template, water spray material, impermeable layers, polymer modified mortar and the like.
2. For the nature of the electrochemical corrosion of steel, steel to eliminate the use of chemical principles of fundamental electrochemical corrosion. This type of measure such as cathodic protection, electrochemical desalination (again simplified) and technology can improve the rust inhibitor of steel corrosion resistance.
3. The use of hard or corrosion resistant material wrapped or coated on the surface of steel, such as layers of reinforced epoxy, steel and other stainless steel cladding.
4. The use of low water conservation fully wet glue double-doped high-performance concrete, can significantly improve the permeability of salt. In this concrete layer having an appropriate thickness of the protective layer is to improve the durability of the basic measures.
