The fittings were made using ASTM A403 WP316L, and the specifications are DN1800, DN2000 with the thickness of 8mm, which had been tailored produced as per confirmed drawings by both parties. All the fittings had been inspected as per stipulated ITP files by the appointed TPI before delivery. Because of the ultra-high size, the open top containers were used to load them properly. The inner ring support was applied to avoid deformation of O.D. during the transportation.
