Epoxy Fire Protection: Epoxy intumescent coatings are intended for use in fire risk areas where evacuation and maintaining asset integrity is essential. Intumescent coatings provide a durable coating able to withstand corrosion when used in a system.

Metallisation – Zinc/Aluminium: Thermally sprayed coatings, zinc or aluminium, are applied through gas or electric arc equipment where the wire is melted and fluidised metal is propelled onto substrate. This method provides a tightly adhering protective coating which protects the metallic substrate through anodic protection. This is a costly process but provides excellent long term protection.

Cement Mortar Lining (CML): Widely used in the containment and conveyance of water. CML provides good long term protection in process industries which require non-potable water. Within the UK the CML is required to be top-coated with an approved DWI Epoxy to allow consumption through the water utility networks.

Epoxy Coating – Above/Below Ground: Epoxies are an extremely versatile anti-corrosion coating system; they are inherently resistant to a large range of chemicals and can be used in almost any environment either alone or as part of a multi-coat system. Although not stable in ultra-violet light they can be top coated with protective polyurethane to maintain stability.

Tape Wrapping – Above/Below Ground: Cold applied tape wrap systems have been used throughout the world and continue to provide protection to pipelines. The tape is made from a lamination of butyl rubber and PVC carrier which together can provide good long term corrosion resistance. This is a low cost protection system which can be applied in both factory or field environments.

Bitumen Enamel – Buried Pipelines: Bitumen enamel was the industry standard coating system for many pipelines throughout the 20th century; within Europe this has been replaced by 3LPE. Bitumen is still used around the world and within the UK as an anti-frictional coating to reduce the force required to drive tubular piles within the construction industry.

Polyurethane Pipelines – Buried: Polyurethane is an extremely tough coating used as an anti-abrasion lining or an external coating system for pipes in difficult environments. For horizontal directional drill projects or thrust boring high build polyurethanes are used to protect both the substrate and any underlying coating from mechanical damage during installation.

Valve Coating – Buried: Due to the versatile properties of polyurethanes they can accommodate the most difficult configurations. Oil/gas valve coating is often specified with polyurethanes to provide long term protection for these high value assets. Hot applied polyurethanes can be applied around the entire surface to provide excellent anti-corrosion protection together with mechanical protection.

Heat Shrink Sleeves: Heat shrink sleeves are a cost effective solution for long term pipeline protection in buried or atmospheric conditions. It is critical to apply the correct temperature during application. Insufficient temperature will not be obvious without performing an adhesion test. For this reason it is best practice to perform qualification trials prior to installation.

Fusion Bonded Epoxy (FBE): Fusion bonded epoxy is a long term solution for anti-corrosion protection and provides quick cure and turnaround on coated items. FBE can be single layer or dual layer where an additional mechanical protection is required. The steel is heated to around 200-240oC and powder is transferred via electro-static guns or fluidised bed.

Polyethylene Marine Protection: When assets are installed in the most difficult marine environments corrosion is not the only issue. Abrasion and erosion can lead to premature failure through multiple impacts from media suspended in sea wash. We have successfully used polyethylene sea shield systems to extend the life of marine assets.

3LPE /3LPP – Buried Pipeline: 3 Layer Polyethylene (3LPE) & 3 Layer Polypropylene (3LPP) have become the industry standard for pipe coating. A first layer of fusion bonded epoxy is followed with a second layer of co-polymer adhesive with a final application of either polyethylene or polypropylene. Polyethylene is used for lower temperatures and polypropylene chosen for higher temperatures.

Field Application of Polyurethanes: Due to the proven longevity of polyurethane through accelerated testing and historical performance these are used for buried pipeline coatings where planned maintenance would not be possible. Field application is possible through specialised equipment often referred to as Hydracats.

Elastomeric coatings: Elastomeric lining/coatings are used extensively in the process industries to provide resistance against chemicals and abrasive media. Neoprene, polychloroprene and EPDM are all used to protect pipes and vessels. These materials are cross linked after vulcanisation to offer an extremely tough lining. Applications can also be used for the external of riser pipes in offshore pipelines.
