Horizontal directional drilled pipelines are often challenged with concerns of coating damage from the abrasion of pull back. Field joints, often considered the weakest point within a pipeline, have the highest risk of incurring damage. Pipeline repair is not typically possible on pipelines installed by trenchless technologies; repulling pipe can be costly and put a project well over budget. Fortunately, Neptune Research Inc (NRI) has an effective field joint coating solution to protect pipelines. Scar-Guard® provides unrivaled protection against impact, abrasion, gauge, punctures and tears. If you are interested in learning more about this state-of-the-art line such as Abrasion Resistant Overlay (ARO) or other field joint coating products, contact us today.
What is Field Joint Coating Protection?
A field joint is the area where two individual steel pipeline sections meet and are welded together. Offshore pipeline coating protection for field joints provides thermal insulation to protect against mechanical stresses related to horizontal directional drilling and extreme temperatures. Field joint coating is necessary to prevent cracks, failures, and cold spots.
What is an Abrasion Resistant Overlay (ARO)?
Abrasion Resistant Overlay/Overcoats (ARO) are designed to increase properties required for anti-corrosion coatings to survive the stresses that cause coating damage during HDD pipeline installations.
Field Joint Coating Protection & ARO Procedure by NRI
The patented Scar-Guard® line of products protects field joints from the mechanical stresses related to horizontal directional drilling coatings, boring and micro-tunneling of pipelines, thereby reducing the potential of damage to the pipe that is installed in an inaccessible manner, allowing the anti-corrosion coating to protect the pipe for the duration of its life expectancy. Simple and easy to install, Scar-Guard® is a composite abrasion resistant overcoat made up of fiberglass cloth and pre-impregnated flexible resin. The field joint coating protection procedure involves simply wrapping the product onto the existing coating’s surface while spraying it with water to activate. There is no field mixing or saturation required! As the industry leader in the development, manufacturing and marketing of breakthrough advances in pipe repair, composite pipe repair, pipeline corrosion protection, and reinforcement technologies, NRI offers the ultimate field joint coating protection.
Horizontal Directional Drilling Pipeline Protection
Horizontal directional drilling (HDD), or directional boring, is a method of installing underground pipe in a shallow arc along a prescribed bore path by using a surface-launched drilling rig. Pipelines going through pullback as a result of HDD can incur damage to the coating integrity due to rocky soil. Pipeline field joint coatings protect the anti-corrosion coatings on the pipelines during the HDD process of laying the pipe and continues to provide long-term protection.
Scar-Guard® Pipeline Field Joint Coating Protection for Horizontal Directional Drilling Coatings
Scar-Guard® allows you to bury, bore or drill with confidence! Scar-Guard® products are so easy to use – they simply wrap onto the existing coating’s surface and are activated by water.
Other benefits include:
- Controlled set time
- Easy to install
- Consistency of application
- Smooth profile
- No UV light or heating required
