DIN 1630 Carbon Steel Seamless Pipes Supplier in China

Standard-Übersicht:
DIN 1630 is a German standard that specifies high-performance carbon steel seamless pipes and tubes. It sets delivery conditions for high-quality, seamless, round, non-alloy steel tubes. DIN 1630 has been mostly withdrawn. It has been replaced by EN 10305-1, a European standard for precision steel tubes. However, DIN 1630 is still referenced for older or legacy applications.

Wichtigste Materialien:
Carbon Steel. Specifically, it covers low-carbon steel pipes with different carbon contents:

  • St 37.4 grade: carbon content up to 0.17%, manganese content down to 0.35%
  • St 52.4 grade: carbon content up to 0.22%, manganese content up to 1.60%

Anwendungen:
DIN 1630 steel pipes are used in high-performance, high-quality environments, including:

  • Chemical plant construction
  • Container manufacturing
  • General mechanical engineering purposes
  • Hydraulic systems (seamless hydraulic carbon steel pipes)

Why Choose UNIASEN DIN 1630 Carbon Steel Pipe?

  • Our DIN 1630 seamless carbon steel pipes are made from non-alloy steel. They are seamless, round, and designed for high-performance use.
  • With no limits on working pressure, these pipes are flexible for many uses. They can withstand temperatures up to 300 degrees Celsius. So, they are a reliable choice for demanding environments.
  • Our ST37.4 steel grade is particularly popular for its excellent mechanical properties and versatility. This steel grade meets high-performance standards. It is ideal for building chemical plants, vessels, pipelines, and for general mechanical engineering.
  • Our DIN 1630 seamless carbon steel pipes have detailed specs. They include dimensions, production procedures, steel grades, surface coatings, end types, joint methods, and processing services.
  • We have the perfect solution for you. Whether you need large-diameter pipes for high flow rates or small-diameter pipes for precision applications.
