Phosphating Technology of Seamless Steel Pipe

  Seamless steel pipe is a kind of steel pipe which is subdivided according to the production mode of steel pipe. The well-known production mode is to crimp the pressed steel sheet, make it tubular, and weld the combination at the bending joint. The most obvious feature of this kind of seamless steel pipe is the visible weld seam on the surface. So what are the common uses of this kind of welded steel pipe?

  Firstly, ASTM A106 Gr.B High Quality Carbon Seamless Steel Pipe is transported with the same fluid as other steel pipes. But due to the special weld seam problem of seamless steel pipe, seamless steel pipe is mostly transported with low pressure fluid. Not only the welding process affects the actual use of steel pipe and the goods transported, but also the steel plate selected for seamless steel pipe determines the use of welded steel pipe.

  Of course, for the pipeline transportation path, the size of diameter and its use is also a great relationship. Large diameter type of seamless steel pipe is more widely used in urban sewage transportation. Seamless steel tubes with smaller diameters are used to blow oxygen to steelmaking.

  Phosphating process of precise seamless steel pipes. Principle of Phosphating of precise seamless steel pipes. Phosphating process of precise seamless steel pipes is that phosphating parts are immersed in phosphating solution and deposited on the surface to form a crystalline phosphate conversion film insoluble in water, which is called phosphating.
