Several Methods to Control the Corrosion of SSAW Steel Pipe

According to the spiral submerged arc welded pipe corrosion mechanism, has put forward a variety of protective measures, this protection can basically be divided into the following types:
1, the harmful substances in the environment from the outside gradually invaded features, including permeability using a series of technical control templates, water spray material, impermeable layer, polymer modified mortar and so on.
2, for the nature of electrochemical corrosion of steel, eliminating the use of the basic principles of electrochemical corrosion of steel. Such measures as cathodic protection, electrochemical desalination (again simplified) and technology can improve the corrosion protection of steel.
3, use hard or corrosion-resistant materials wrapped or coated on the steel surface, such as layers of reinforced epoxy, steel and other stainless steel cladding.
4, the use of low water wet glue double high-performance concrete can significantly improve the permeability of salt. A protective layer of suitable thickness in such a concrete layer is a basic measure to improve durability
