Product Description
R4 H-type Joining Shackle (LTM)
1. Mooring chain Introduction:
Depending on the nominal tensile strength of the steels used for manufacture, chains are to be subdivided into five grades, i.e.: R3, R3S, R4, R4S, and R5.
Diameter:34mm-162mm
Grade: R3, R3S, R4, R4S, R5
ABS, LR, BV, DNV, CCS Certificate
Applications: offshore oil platform, offshore oil storage ship, offshore buoys, fishing farm, and aquaculture purposes.
For semi-submersible drilling platforms, floating production and storage tankers and other offshore development facilities, Marine mooring chain products are required to not only have high strength and toughness, but also have seawater corrosion resistance, fatigue resistance, wear resistance and other properties of the mooring chain steel due to long-term immersion in sea water. Stud mooring chains have been used for MODUS and FPSOS moorings in shallower waters. It has proven to be powerful, reliable and relatively easy to handle. The rung provides stable connections between links and ease of hoisting.
