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.

DIN 1629 seamless pipeSeamless Pipes and Tubes for Pressure Applications

The EN 10216 Euronorm re places the old DIN 17175 and DIN 1629standards. This standard is designed for pipes used in pressure applications, such as a pipeline. This is why the associated steel qualities are designated by the letter P for ‘Pressure’. The value that follows this letter designates the minimum yield strength. The subsequent letter designations provide additional information.

Measurement the JIS seamless pipe

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

How to calculate a steel pipe and tube theoretic weight

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.

Square hollow section, rectangle hollow sectionSquare hollow section, rectangle hollow section

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).
Most HSS are of circular or rectangular section, although other shapes are available, such as elliptical.

Igot production The Manufacturing Process of steel pipe

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.
