DIN 2458 Welded Steel Pipes and Tubes

DIN 2458 Welded Steel Pipes Supplier

DIN 2458 Measurement and length of steel pipes. The outer diameter of the tube is 10.2mm to 2020mm, and the wall thickness is 1.6mm to 20mm.

This kind of tube is usually different from the same type of steel construction, like St 37.0 (equivalent to S235JRG2) or St 37.2 (equivalent to S235JRG1).

DIN 2458 Manufacturing methods for use with pipes (ERW), line-backed arc-fired (LSAW), Japanese spiral arc-fired (SSAW). 3PP (3PP), PTFE and other packaging options. The pipe ends can be beveled, plain, or coupling types, offering flexibility in joint methods.

Compatible with other international standards (as per API 5L, ASTM A53 and EN 10217-1), and therefore used throughout the world.

DIN 2458 suitable for many industrial applications. This is a comprehensive low-priced Chinese-Japanese fluid transportation, gas furnace, oil and natural gas industry. Appropriate use of Yuanjing, Chemicals, Electronics Shipbuilding.

Why Choose DIN UNIASEN 2458 Pipe?

DIN 2458 steel pipes are available in different steel grades for easy identification and selection. The pipes have a grade symbol and material number, the symbol is St37.2 and the DIN 2458 material number is 1.0037.These designations are easy to distinguish from other carbon steel grades.
Our DIN 2458 steel pipes are designed with a comprehensive range of specifications to meet your unique needs. Sizes range from OD 10.2mm to 2020mm, and wall thicknesses range from 1.6mm to 20mm. Production procedures include seamless, welded, and ERW methods, ensuring the highest quality and precision.
The pipe ends can be beveled, flat, or coupled, providing flexible connection methods.
Available surface coatings include 3LPE and PTFE for additional protection and longevity.
Our DIN 2458 St 37.0 pipes are designed to meet stringent mechanical requirements. They have a minimum yield strength of up to 235MPa and a minimum tensile strength of up to 510MPa.
Our DIN 2458 steel pipes are made from materials that include carbon, silicon, nitrogen, phosphorus and sulfur. Pipes can also have nitrogen-binding elements added to enhance product strength.
Our DIN 2458 St 37.0 pipes are fully deoxygenated and supplied in a fully sterilized form. They are designed to withstand high temperatures and pressures, making them ideal for use in boilers, heat exchangers and power plants.
