Tennexor is a spray-applied polyurea coating engineered to protect buried oil & gas pipelines from handling damage, roller cradle abuse, trench contact, and rocky backfill — without the seams, wrinkles, or tear risks of traditional wrap systems.

Coating damage during pipeline construction is an integrity-critical issue. Tennexor is engineered to protect anti-corrosion coatings at every high-risk stage — from the stringing yard to final backfill.
Pipe is subjected to mechanical contact, strapping, and dragging during yard handling and stringing operations.
Sustained point-loading from roller cradles and support equipment compresses and abrades the anti-corrosion layer.
The lowering-in phase creates scraping, impact, and point contact with trench walls.
Coarse, rocky, or debris-laden backfill delivers repeated high-energy impact and abrasion across the entire pipe circumference.
Ongoing soil stress, ground movement, and cathodic protection requirements demand a durable, CP-compatible protection layer.
No wrapping. No overlap management. No seam weak points. Tennexor sits directly in the field coating → lowering → backfill sequence.
Base anti-corrosion coating applied and cured. Surface confirmed clean and ready for mechanical protection layer.
Tennexor sprayed to target thickness in a single pass — forming a seamless, monolithic protective shell around the full pipe circumference.
Fast cure time means the pipe is quickly returned to the handling and lowering sequence — minimising project downtime.
Pipe is lowered and backfilled with full mechanical protection in place. Tennexor absorbs roller contact, trench impact, and rocky backfill throughout.
Protects the underlying anti-corrosion coating from impact, abrasion, and point loading during lowering and backfilling — the same hazards incumbent rockshield products are built to address.
Construction Phase CriticalUnlike wrap systems that require overlapping and field securement, Tennexor forms a seamless, uniform protective layer — eliminating the operational variability of seam-based systems.
No Seam Weak PointsTennexor maintains uniform contact under sustained roller loading — it will not wrinkle, bunch, or slip. Critical for above-ground handling, pipeline lay equipment, and offshore lay barge operations.
No Wrinkling Under LoadHigh-elasticity polyurea absorbs repeated impact from rocky, coarse, or debris-laden backfill material. Pipe integrity is maintained even in challenging trench conditions.
Rocky Trench RatedFewer material handling steps, no roll management, no fastening consumables. Tennexor simplifies the field application workflow — reducing labour hours and installation variables on every joint.
Faster Field ApplicationCathodic protection compatibility is a must-have for buried pipeline protection. Tennexor is formulated to be compatible with CP systems — ask for our CP compatibility statement and test data.
Cathodic Protection SafeTennexor directly competes with traditional mesh and fabric wrap systems at every key specification category pipeline engineers and project managers evaluate.

Tennexor protects anti-corrosion coatings from mechanical damage during the most critical phases of pipeline construction — handling, roller cradle contact, lowering-in, and rocky backfill. Damage at these stages can compromise coating integrity before the pipe is even in service.
Yes. Tennexor is designed as a direct alternative to mesh, fabric, and cushioned wrap rockshield systems. Its spray-applied monolithic construction eliminates the seams, overlaps, and field fit-up variability associated with wrapped products.
Tennexor will not wrinkle, bunch, or displace under sustained roller load. Its bonded, monolithic structure maintains full contact with the pipe surface throughout all handling and lay equipment operations — including offshore lay barge rollers.
Yes. CP compatibility is a critical requirement for buried pipeline protection and Tennexor has been formulated accordingly. A CP compatibility statement and supporting data are available on request from our technical team.
Tennexor can be applied in both coating yard (shop) and field environments using a standard plural component spray unit. Contact our application specialists for equipment recommendations and field application guidance.
Tennexor is designed for use on buried oil and gas pipelines from 12 inch to 48 inch nominal diameter. Contact our team for guidance on application to larger or smaller pipe sizes.
