William Hackett Lifting Products launch the newest addition to their world leading range of offshore master links and quad assemblies: New generation corrosion resistant master links and quad assemblies incorporating the latest Zinc-ToughTM Technology.
The HA range of master links and quad assemblies are widely used for offshore rigging as well as container lifting sets. Having the Zinc-Tough option provides enhanced corrosion protection and therefore further mitigates against the risks of hydrogen embrittlement (HE) and hydrogen assisted stress cracking (HASC).
Hydrogen embrittlement is a process by which metals such as steel become brittle and fracture under stress due to the introduction and subsequent diffusion of hydrogen into the metal- it can also be described as hydrogen assisted stress cracking and is particularly prevalent in the extreme conditions of the offshore environment where corrosion is a constant threat. William Hackett and McKinnon chain combined technical knowledge and worked alongside a wide range of stakeholders, including several major oil and gas operators to develop Zinc-ToughTM Technology.
This unique manufacturing process delivers a master link with the tensile strength requirements to deliver a 5:1 safety factor with a hardness value as low as 34-36 HRC. The DNV charpy impact values are achieved at -40C making the links ability to withstand a shock load at any operating temperature.
These innovative master links and quad assemblies are certified to international standards: DNV2.7-1, DNV2.7-3, BSEN ISO 10855-2, EN1677-4, ASME B30.26 and API-2CCU-Aug.2017. DNV Type Approval TAS00001BN Rev 2.
Available in diameters from 16mm up to 75mm and working load limits from 4.1 tonne to 100 tonnes. All are individually proof load tested to 2.5 times the working load limit and 100% MPI.
