Weldable structural steels for fixed offshore structures. Technical delivery conditions - Hot finished hollow sections Ingestion-build-228203 BS 7543 gives guidance onWhat is this standard about? This document specifies requirements for weldable structural steels made of hot finished seamless and high frequency welded hollow sections to be used in the fabrication of fixed offshore structures. The following thickness limitations are given in this standard: for seamless hollow sections up to and including 65 mm; for HFW hollow sections up to and including 25,4 mm. Greater thicknesses can be agreed, provided the
