ASTM Standard grades
Dimensions from carbon steel pipes are defined in the ASME B31.10M standard, dimensions for stainless steel pipe are defined in the ASME B31.19M standard. The material qualities for these pipes are defined in the ASTM standards.
These ASTM standards, define the specific manufacturing process of the material and determine the exact chemical composition o

Seamless steel pipe is alos called CDS pipes (Cold drawn seamless pipe). It’s is used widely in maching parts, shafts, bearings, cylinders having strength of 75000 PSD tensile. It is a solid carbon steel rod which is pushed on to the mandrel to form the shape of tube. It is availabe in different sizes.

Steel pipes are made by two different processes. The overall production method for both processes involves three steps. First, raw steel is converted into a more workable form. Next, the pipe is formed on a continuous or semicontinuous production line. Finally, the pipe is cut and modified to meet the customer’s needs.

Ingot production

Igot production

The molten steel is then poured into large, thick-walled iron molds, where it cools into ingots.

Molten steel is made by melting iron ore and coke (a carbon-rich substance that results when coal is heated in the absence of air) in a furnace, then removing most of the carbon by blasting oxygen into the liquid. The molten steel is then pour

A hollow structural section (HSS) is a type of metal profile with a hollow tubular cross section. In some countries they are referred to instead as a structural hollow section (SHS).

A tube, or tubing, is a long hollow cylinder used to convey fluids (liquids or gases).

Square hollow section, rectangle hollow section

Most HSS are of circular or rectangular section, although other shapes are available, such as elliptical. HSS is only composed of structural steel per code.
HSS is sometimes mista

The weight of a pipe depends on the weight density of the material that composes the pipe as well as the physical volume of the pipe. Weight density measures the amount of compactness of the pipe material expressed in pounds per cubic foot.

Measurement the Wall thickness of seamless pipe

We have the professional engineers, measurement the size of steel pipes.

The volume of a pipe equals its surface area times its thickness. Specifically, the surface area of a pipe is the same as a cylinder and equals the number of square inches that can cover the curved sides of the pipe.
