Seamless steel pipe can be said that the pricing pattern of deposit interest rates with hierarchical, orderly and differentiated competition has basically taken shape. The further enlargement of the upper limit of floating range of deposit interest rate for seamless steel pipe manufacturers is another important measure for the market-oriented reform of deposit interest rate in China. This not only broadens the independent pricing space of seamless steel pipe financial institutions, but also helps to further exercise the independent pricing ability of seamless steel pipe financial institutions, accelerate the transformation of their business models and improve the level of financial services, lay a more solid foundation for the ultimate liberalization of the deposit interest rate ceiling, and help capital prices reflect the relationship between market supply a...

　　Galvanized steel pipe rust removing method 　　1. First, the surface of steel is cleaned by solvent, and the organic matter on the surface is removed. 　　2. Then use tools to remove rust (steel brush), loose or inclined scale, rust, welding slag, etc. 　　3. Use pickling method. 　　Welded connection 　　1.  ASTM A106 Sch 20 Hot Dip Galvanized Steel Pipe  nozzle is not in a straight line after butting and there is a problem of beveling in the steel pipe. It is suggested that the pipe nozzle should be cut off for a short period before processing. 　　2. After the butt of galvanized steel pipe orifice, the butt of two pipe orifices is not strict, resulting in uneven thickness of weld orifice; and the ellipse of pipe orifice caused by the collision of steel pipe due to its own reasons or transportation. It is suggested that the pipe head be cut off for a short period and then processed. 　　3. After the butt joint of galvanized steel pipe, there are zinc nodules at the pipe m...

　　Carbon steel pipes can be divided into hot-rolled and cold-rolled (drawn) steel pipes. 　　Hot rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. 　　Cold rolled (dialed) carbon steel pipes include general steel pipes, low and medium pressure boiler pipes, high pressure boiler pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes and other carbon steel pipes. They also include carbon thin-walled steel pipes, alloy thin-walled steel pipes, stainless thin-walled steel pipes and special-shaped steel pipes. The outer diameter of hot-rolled seamless pipe is generally larger than 32 mm, the wall thickness is 2.5-75 mm, the outer diameter of cold-rolled  ASTM A178 ERW Carbon Steel Pipe  can reach 6 mm, the wall thickness can reach 0.25 mm, the outer diameter of thin-walle...
