Galvanized pipes must have an adherent and continuous layer of zinc on the interior and exterior surface. the covering with zinc of both surfaces or only the inner surface is achieved by submersion in a molten zinc bath. local roughness and thickening of the zinc layer is allowed, mainly on a portion of 80 mm from the end of the pipe, where the blowing of the tubes is executed. the thickness of the zinc layer on the outer surface must be thinner than the layer of the inner surface. the thickness of the interior surface must be approximately 56 µm. the linear mass of galvanised pipes is calculated by adding the mass of the coresponding minimal thickness of the zinc layer to the mass of the pipes.
Galvanized pipes have a wide range of uses. in addition to oil and other low-pressure fluid pipelines, it is also used as oil well pipes in the petroleum industry, especially in offshore oil fields, oil heaters in chemical coking equipment, coal distillation, and oil washing converter pipes, bridges, etc. pipe pile, mining tunnel support frame with pipe, etc. developed countries in the world started to develop new pipes and continuously banned galvanized pipes.
