DIN/EN 1629 is a standard specification for seamless circular tubes of non-alloy steel with special quality requirements. This standard includes different grades such as St37.0, St44.0, St52.0, which are intended for use in the construction of chemical plants, vessels, pipework, and for general mechanical engineering purposes. The tubes manufactured according to DIN/EN 1629 have a wide range of applications and are known for their high durability and resistance to corrosion.
Note: DIN/EN standards have been replaced by European Standards (EN) since 1984, but some of them are still used today.
