Vietnam's strategic industrialization drives massive growth in energy transportation, municipal networks, and marine construction. Mega-projects such as the Block B - O Mon gas pipeline development, coastal refinery expansions in Dung Quat and Nghi Son, and regional LPG terminals require world-class corrosion mitigation strategies. However, local environments pose intense challenges to structural steel assets.
1. Sustained High Relative Humidity (up to 95%): Accelerates atmospheric oxidation during field assembly. Pre-heating and surface preparation require strict control to prevent flash rusting.
2. High Salinity and Acid Sulfate Soils: Deltaic regions in the Mekong and Red River basins contain highly corrosive soils. Cathodic disbondment and chemical attack are constant risks without premium barrier tapes.
3. Heavy Ground Aggression during HDD: Horizontal Directional Drilling through rocky or variable terrain exposes pipelines to high mechanical friction, demanding ultra-tough composite outer-wraps.
Modern steel pipeline design requires high-performance polyolefin coatings. At CYCT, we engineer solutions complying with internationally recognized standards:
Heat-shrinkable products utilize a radiation cross-linked high-density polyethylene (HDPE) backing coated with a specialized copolymer hot-melt adhesive. During field application, the heat of a propane torch shrinks the backing while melting the adhesive. This reaction creates a continuous, high-shear barrier that bonds tightly to the pipe surface and factory PE/FBE coatings. This configuration prevents moisture migration and withstands cathodic protection stresses.
CYCT New Materials Company Limited (for short, CYCT) is a state-level high-tech enterprise integrating R&D, production, and sales of pipeline corrosion protection materials, as well as buried pipeline detection services and pipeline coating field application services into one.
CYCT has dedicated decades to the R&D, production, and sales of pipeline corrosion protection materials. Today, CYCT maintains leading testing and R&D capabilities, supported by a professional R&D team and a national CNAS-accredited laboratory.
CYCT has served as a stable supplier of field joint coatings for years to major operators including PetroChina, Sinopec, PipeChina, and various local gas pipelines, holding a dominant market share. Additionally, CYCT has successfully developed and introduced specialized corrosion protection materials, including viscoelastic materials, photo-curing protective sleeves for trenchless HDD, and polyurea coatings.
Through close cooperation with leading research institutes, such as the CNPC Pipeline Science Research Institute, CYCT provides in-service pipeline operators with technical services. These include buried pipeline inspections, design scheme optimization, cathodic protection configuration, pipeline rehabilitation projects, and integrated safety protection solutions.
Our commitment to quality has earned CYCT corporate memberships and accolades across key industry groups:
Specialized systems engineered for diverse municipal, chemical, and offshore structures.
Designed specifically for polypropylene (3LPP) coated pipelines operating at elevated service temperatures up to 110°C.
A heavy-duty cold-applied wrap designed for corrosion prevention on high-temperature processing pipelines in refinery environments.
High-build liquid epoxy primer that acts as the primary layer in 3-layer polyolefin systems, offering protection against cathodic disbondment.
Designed for hot-water and hydrocarbons transmission systems, offering excellent mechanical defense against soil movements.
Applying heat shrinkable tape in tropical climates requires specific operational precautions to avoid common coating failures:
During a gas pipeline crossing of the Mekong Delta, standard 3LPE field joint coatings faced risk of shear damage. By implementing our FRP Fiberglass Outer-wrap (FRP Shield) over the heat-shrinkable sleeve, the pipeline resisted frictional drag forces during pullback, maintaining 100% coating integrity without holiday defects.

Fiberglass wrap activated by ambient humidity. Formulated to protect offshore structures and splash-zone piping.
Features high-strength fabric backing embedded in viscoelastic compound, offering excellent shear and flow control.
Corrosion mitigation technologies are shifting from high-temperature installation systems to cold-applied, self-healing materials and fast-curing composite shells. Key focus areas include:
Traditional shielding tapes require long cure times or flame heating. Our advanced UV-curing sheets polymerize rapidly under natural sunlight or portable ultraviolet lamps, establishing a high-hardness shell over primary corrosion barriers in under 30 minutes. This technology is ideal for offshore structures and splash-zone piping.
By using non-crystalline low-molecular-weight polymers, viscoelastic materials maintain cold-flow behavior, automatically sealing minor mechanical holidays. They require minimal surface preparation (SSPC-SP2/Sa 2) and offer an efficient solution for rehabilitation projects where sandblasting is not feasible.
