A53 Carbon Steel Grade B Pipe China Manufacturers & Suppliers

A53 seamless steel pipe is a material of American Standard steel pipe, of which A53-A is equivalent to Chinese 10# steel, A53-B is equivalent to Chinese 20# steel, and A53-F is equivalent to Chinese q235 material.

The main production process of A53 seamless steel pipe is cold-drawn and hot-rolled, the main difference between the two cold-rolled seamless steel pipe production process is generally more complex than hot-rolled, the appearance of cold-rolled seamless steel pipe is shorter than hot-rolled seamless steel pipe, cold-rolled seamless steel pipe wall thickness is generally smaller than hot-rolled seamless steel pipe, but the surface looks more shiny. The surface of the hot rolled steel pipe is rougher.

Carbon Steel Welded Pipe

Carbon Steel Welded Pipe

Seamed steel pipe is also called welded steel pipe, which is made of carbon steel that can be easily welded, and it is generally nominal in size, and the nominal size often used is DN15 to DN100, while DN150 is the maximum nominal diameter. Seamed steel pipe is often used to transport low-pressure fluids such as gas, cold water, hot water, etc., for which it is also called gas pipe, water pipe, etc.

Carbon Seamless Steel Pipe

Carbon Seamless Steel Pipe

Seamless steel pipe is made of whole round steel by piercing, and the surface is generally without welded seams. There are many kinds of seamless steel tubes, such as: top tube, cold drawn tube, cold rolled tube, hot rolled tube, extruded tube, etc. If the classification is based on the shape of the section, it can be divided into two kinds, respectively, shaped tube, round tube, which can also be divided into a variety of complex shapes, such as: star-shaped tube, square tube, round tube, triangular tube, hexagonal tube, etc.. If the classification is based on the use, it can be divided into two kinds, respectively, thin-walled tube, thick-walled tube.
