soldagem de aço carbono - UNIASEN

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.
