Tech & service

Seamless Pipe. Tubular product made without a welded seam, manufactured in a hot-forming process using an extrusion or drawing process that can be followed by cold sizing or cold finishing to produce the desired shape, dimensions and properties.

  • carbon steel pipe
  • DIN/EN Steel Pipe
  • JIS seamless pipe
  • pipes by applications

Range of Applications >>

Steel pipe are ubiquitous and can be found underground and within residential walls, laboratories, and commercial and industrial structures.

The usage of Carbon steel pipe

Carbon steel pipe is widely used in the world of manufacturing as they have high end durability. It is one of the preferred pipes when it comes to stamina and cost. Steel tubes of different sizes and shapes can be created with use of modern technology.
There are many different ways to use this and what you can do with it.

ASTM Standards for steel pipes

ASTM’s steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.


What is DOM tubing used for

DOM Steel Tube is produced using uniformly high quality C1020 steel strip and is formed and electric resistance welded into its basic shape.


What is JIS?

Japanese Industrial Standards (JIS) specifies the standards used for industrial activities in Japan. The standardization process is coordinated by Japanese Industrial Standards Committee and published through Japanese Standards Association.


German Institute for Standardization (DIN)

DIN (Deutsches Institut für Normung ) standards for topics varying from agriculture to vehicle manufacturing in Germany.

Type:seamless steel pipe:1/2″-24″; ERW steel pipe:1/2″-48″
Condition on delivery:

Term Symbol Explanation
Cold-finished/hard
(cold-finished as-drawn)
BK No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
Cold-finished/soft
(lightly cold-worked)
BKW After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.
Annealed GBK After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
Normalized NBK The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.
