1) Remark: The steel StE 445.7 TM is produced as welded tube in the conditions thermomechanical treated. Tubes of this steel are conform acc. 5L, 5LX and 5LS of the American Petroleum Institute (API). The Attention should be paid to the technical regulation for combustible liquids TRbF 301. Application: pipelines for combustible liquids (e.g. petroleum and his products) and for compressed or liquid combustible gases
