Offshore & Subsea
Fastening Solutions for Extreme Environments
In the offshore and subsea sectors, reliability is paramount. Every component must withstand extreme pressures in corrosive environments: our fastening solutions are engineered to meet these challenges head-on.
Ensuring absolute reliability, our production control and documentation procedures have been refined to meet the rigorous standards of the nuclear industry. As a testament to our commitment to quality, we hold API 20E (BSL 1, 2, 3) and API 20F (BSL 2 & 3) accreditations (Reg. No. Q1-3317).
Our expertise in forging and heat treatment of Inconel™ 718 and Super Duplex materials gives us a unique advantage in producing fasteners that excel in demanding offshore conditions. With a broad selection of exotic grades, we provide fastening solutions for critical offshore and subsea applications, including blowout preventers (BOPs), Christmas trees, riser bolt structures, piping, spools, flowlines, and anchors.
