DIN 2448 St 44.0 Seamless steel Pipe 12" SCH160 12M
DIN 2448 is a standard which gives specifications for carbon steel pipes and tubes that are seamless in nature. It includes weights, masses per unit length, couplings, and dimensions. The din 2448 pipe cannot be hot formed with or without consequent heat treatment

We can produce special diameter and wallthickness seamless pipes. Adopted standards: ASTM A106, ASTM A53, API 5L GR.B, GB/T8163,EN10216 etc
The diameter range from 1000m to 1600m, wallthickness from 20- 400mm. The pipes are extensively applied for nuclear power station and other key project.
