China Cheap Seamless Steel Pipe Suppliers - Wholesale

Seamless Boiler Tube. For Manufacture wall panel,economizer, re-heater, super-heater and steam pipeline of boilders. Generally, the temperature of boiler tubes is below 350 C. Domestic tubes are mainly made of 10 and 20 carbon-bonded steel hot-rolled tubes or cold-drawn tubes. Difference between hot-rolled and cold-rolled seamless Feb 21, 2019 · Hot rolled seamless steel pipes are generally produced on automatic rolling mill units. The solid tube blank is inspected and the surface defects are removed, cut into the required length, centered on the end face of the perforated end of the tube blank, then sent to a heating furnace for heating and perforated on the punching machine.

How to distinguish hot rolled and cold rolled seamless

As an important part of steel products,steel pipes are divided into two categories,seamless steel pipes (round billets) and welded steel pipes (plate with blank) because of their different manufacturing processes and the shape of the pipe blanks used.Generally seamless steel pipes are made by hot rolling or cold rolling with 10,20,30,35,45 high quality carbon steel and 16Mn,5MnV low alloy How to distinguish hot rolling and cold rolling seamless tube?Hot rolled seamless steel pipe is generally divided into low, medium, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, geological steel pipe and other steel pipe. The outside diameter of hot rolled seamless tube is generally greater than 32mm and the wall thickness of that is 2.5-75mm.
