DIN 2470-1 Steel gas pipelines – pressure up to 16 bar.
DIN 2470-2 Steel gas pipelines – pressure exceeding 16 bar.
DIN 17172 Steel pipes for pipelines for the transport of combustible fluids and gases.

Steel grades:

according to EN ISO 3183-PSL1: L210, L245, L290, L320, L360, L390, L415, L450
according to EN ISO 3183-PSL2: L245NE, L290NE, L360NE, L415NE
according to DIN 2470-1/1629: St37.0
according to DIN 2470-2/17172: StE210.7, StE240.7, StE290.7, StE320.7, StE360.7, StE415.7

Applications

This group of tubes is mainly set for high pressure pipelines to deliver gases, oil and other flammable fluids in the mining, chemical and energy industry.

Delivery condition

Usually the tubes are supplied as hot rolled. Only the tubes with DN 6-10 and sometimes other dimensions are supplied as cold drawn and heat treated after forming. This is done upon agreement.
