Coated steel pipe would have a good resistance for corrosion during the whole transmission process. And for ERW steel pipe, there are some benefits once we apply coating on it too. The basic function of ERW steel pipe would have two main aspects: It would be a good helper for ERW steel pipelines as the coating will make the surface of tubes away from electro-chemical corrosion of soil medium, the basic physics of bacterial corrosion protection. Then, it would have good performance for resisting on various stresses. Such as resisting the move of the soil medium creep stress, static stress and abrasion force method and structure of the basic machinery protection.
