Stainless steel tube

Stainless steel tube rolling methods include hot rolling, hot extrusion and cold drawing stainless steel pipe. According to the different microstructure of stainless steel divided into half ferritic half martensitic stainless steel tube, martensitic stainless steel tube, austenitic system stainless steel tube, austenitic - ferritic iron series stainless steel tube.

Carbon steel square pipe

Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes. Hot rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipes. Cold rolled (dial) carbon steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, other steel pipe, also includes carbon thin-wall steel pipe, alloy thin-wall steel pipe, stainless thin-wall steel pipe, special-shaped steel pipe. The outer diameter of the hot-rolled seamless pipe is generally greater than 32mm, the wall thickness is 2.5-75mm, the outer diameter of the cold-rolled seamless steel pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, the wall thickness is less than 0.25mm, and the size accuracy is higher than that of the hot-rolled seamless pipe. General carbon steel pipe: is made of 10, 20, 30, 35, 45 and other high-quality carbon junction steel 16Mn, 5MnV and other low alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot rolled or cold rolled. Seamless pipes made of low carbon steel such as 10 and 20 are mainly used for fluid transport pipelines. 45, 40Cr and other medium carbon steel seamless pipe to manufacture mechanical parts, such as cars, tractor parts. Generally used carbon steel pipe to ensure strength and flattening test. Hot-rolled steel pipes are delivered in hot-rolled or heat-treated condition; Delivered cold rolled in heat-treated condition.

Galvanized welded steel pipe

In order to improve the corrosion resistance of steel pipes, general steel pipes (black pipes) are galvanized. Galvanized steel pipes are divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has a thick galvanized layer, while electro-galvanizing has a low cost.

Details

Galvanized seamless steel pipe

Hot-dip galvanized seamless steel pipe: The hot-dip galvanizing amount is higher, and the average galvanized layer thickness is above 65 microns. Its corrosion resistance is much higher than that of hot-dip galvanized pipe.
