Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc.
Anti-corrosion steel pipe is processed through the preservation process, which can effectively prevent or slow down the process in the transport and use of chemical or electrochemical corrosion reaction of steel pipe.
Our staff are qualified and certified according to all current welding procedures, thus guaranteeing our customers longitudinally welded stainless steel pipes in line with the requirements.
