tri-star industries lead

Tri-Star Industries is a manufacturer and supplier of rust-resistant nuts, bolts and other fastening solutions designed for use in oil and gas, power and petrochemical applications worldwide.

We provide an array of DNV-approved cathodic protection (CP) and pipeline inspection services for organisations operating in marine locations, which help preserve and safeguard the structural integrity of offshore assets and machinery.

MASTERCOTE fasteners for use in offshore applications

Tri-Star’s MASTERCOTE range of robust, polytetrafluoroethylene (PTFE) coated fasteners have been proven during salt-spray testing to last up to 9,000 hours without showing traces of rust or corrosion.

As well as being a highly economical solution, MASTERCOTE parts are also resistant to most acidic chemicals, remaining undamaged even when exposed to hydrogen sulphide at temperatures up to 121°c at 2,000psi.

The DIMET brand has been established in the Cathodic Protection Field since 1970 and is renowned worldwide. The DIMET experience has given us unsurpassed knowledge in the design, manufacture, installation, commissioning and maintenance of the full range of sacrificial anodes, impressed current cathodic protection systems and other corrosion prevention methods.
Tri-Star’s MASTERCOTE range of fastening products is designed to withstand repeat exposure to moisture and corrosive substances, providing customers with reliable, hard-wearing fastening solutions.
The company offers a full catalogue of galvanised stainless-steel products and accessories for offshore sites, including ladders, trays and cantilever arms.
Tri-Star’s user-friendly and ergonomic subsea tensioners makes use of its patented ‘quick snap’ mechanism, and can be manufactured according to clients’ individual needs and specifications.

We stock an extensive list of U-bolts, stud-bolts and foundation bolts in a variety of materials, ranging from heavy-duty carbon and stainless steel to more niche and specialist alloys.

We design and engineer customised fastening products to address clients’ specific needs and requirements. Load-indicating variants are also available.

Tri-Star Industries is a trusted name in the offshore and petrochemical sector, currently holding a global Enterprise Frame Agreement with Shell Global Solutions for all its fasteners requirements.

Alloy Technology, a wholly owned subsidiary of Tri-Star, is a specialist provider of critical, pressure containing fasteners to the subsea and LNG equipment manufacturers.

It is the first and only company in Asia to be accredited by API to use both the API 20E and 20F Monogram.

Sacrificial and Impressed current cathodic protection (ICCP) systems for marine worksites

Tri-Star’s dedicated team of NACE-certified engineers specialise in the design, commissioning, supply and installation of sacrificial anodes and impressed current cathodic protection (ICCP) systems in marine environments.

Our solutions are Shell International Exploration and Production Inc. (SIEP) and DNV Type approved, and can be easily retrofitted with existing structures and pipeline networks.

Tri-Star’s experienced and enthusiastic staff are also well equipped to conduct independent audits and reviews of third-party CP designs, as well as a number of in-depth pipeline CP and coating inspections, for example industry-standard direct current voltage gradient (DCVG) and closed interval protection (CIPS) surveys.

Stainless, Aluminum, FRP / GRP and Galvanized cable ladders and trays for use in offshore environments

Tri-Star’s hard-wearing, NEMA VE-certified products are manufactured from stainless and carbon steel, and galvinised via hot-dipping processes.

Our complete catalogue includes a number of ladders, trays, trunklings, channels and concrete inserts, as well as cantilever arms, trapezes, cleats and various related accessories. Ladders are available in more 6m continuous run lengths on request.

Many items in our product range are available in a number of epoxy, aluminium and FRP-GRP composite finishes, and contain fewer joints and fittings than many similar products on the market, reducing both the time and cost needed for installation.

In addition, we provide consultancy services relating to the installation and bespoke design of our products.

Hydraulic bolt-tightening tools for the oil and gas industry

Tri-Star Industries supplies quality subsea and topside tensioner solutions tailored to customer specifications, designed and manufactured in-house by its committed and accomplished team.

Our innovative, patented ‘quick snap’ reaction nuts contribute to the user-friendliness, reliability and lightweight build of our diver-operated systems, for example the SM Sub-Marine bolt-tensioning tool, which also features a built-in piston-misalignment compensation mechanism for hassle-free application.
