Why not galvanize after welding for steel pipe

Jan 02, 2019 · This paint can be applied to the weld after sand blasting or wire brushing to remove all welding slag followed by wiping the weld clean with a rag. Thermal- sprayed zinc is also effective in restoring corrosion resistance, but the surface has to be sufficiently roughened, usually by sand blasting or coarse abrasive conditioning to enable thermal- sprayed zinc to stick properly.What's the difference between ERW and AC welding?ERW is a electric-resistance welded steel pipe, Resistance welded steel pipe is divided into exchange of welded steel pipe and DC welded steel pipe in two forms. AC welding in accordance with different frequencies are divided into low-frequency welding, IF welding, welding of ultra-IF and high-frequency welding.See all results for this questionWhat kind of pipe is black in color?What are black steel pipes? Black steel pipes are made of steel that has not been coated with a substrate such as zinc or paint. Since it has a dark color surface that is forms by iron oxide during the manufacturing process, it is called black steel pipe.See all results for this question

What are the uses of black steel pipes?
