Greenkote coatings to be used in world's second largest natural gas processing facility 24 May 2019

Greenkote PLC global provider of high-performance anti-corrosion metal coatings, has announced that its Chinese licensee has won a major contract to supply 1,200 tonnes of coated hex bolts for construction of the new Amur Gas Processing Plant (AGPP) in the Amur region of Siberia. When completed, AGPP will be the second largest facility of its type in the world, designed to process 42 billion cubic meters of gas per year.

The Greenkote licensee, Shanghai Premier Tension Control Bolts Co., Ltd. is a joint venture of Tension Control Bolts Ltd. (TCB) of the UK, Shanghai High Strength Bolts Plant Ltd. (SHS) and Shanghai Yan Yan Trading (YYT).

“We're very proud of Shanghai Premier for winning this significant contract. There were six other suppliers competing, and the performance specifications for the coatings were extremely high. Because of the very harsh Siberian environment, the customer required unusually thick coatings as well the need to pass 1000-hour salt spray testing. Shanghai Premier did an excellent job,” said Mark Gore, CEO at Greenkote.

"For the AGPP we are providing a range of Greenkote coated Grade 8.8 and Grade 10.9 hexagon bolt assemblies, 16mm to 30mm in diameter. Our bolts are being used as fasteners for the steel structures throughout the AGPP facility. Deliveries began in October of 2018 and will continue until June of 2019,” commented Yan Wei, vice general manager of Shanghai Premier and General Coordinator of the AGPP project.

Shanghai Premier operates a full state of the art Greenkote coating line and has added significant new capacity to fill the AGPP contract. The company’s Greenkote coated preload bolts, both tension control bolts (TCB) and hex bolts, all meet the most stringent international standards including ISO C5-M which addresses very highly corrosive marine environments.

Greenkote® is a proprietary family of high performance zinc-based coatings that can be applied to ferrous metals and alloys by a patented thermal diffusion process — for fasteners and many other applications. Greenkote replaces many older processes such as hot-dip galvanizing, zinc plating, sherardizing and metal flake coating. In addition to its superior anti-corrosion qualities Greenkote also provides improved adhesion and longer wear, and it eliminates hydrogen embrittlement. Greenkote is also eco-friendly, from which its name derives. Unlike many other anti-corrosion coatings, Greenkote processing is totally free of pollutants. It is fully compliant with ASTM A1059/A1059M, an industry standard specification for zinc alloy coatings.

Notably, in 2016, Greenkote-coated bolts (provided by Greenkote-licensee TCB of the UK), were also selected for use in constructing the New Safe Confinement Shelter over the Chernobyl nuclear power plant site - another world-class application in an extremely harsh environment.
