Engineered to comply with ISO 21809-3, DIN 30670, and NACE SP0169 specifications
CYCT New Materials Company Limited (CYCT) is a state-level high-tech enterprise dedicated to the R&D, fabrication, global delivery, and engineering application of advanced pipeline corrosion protection systems. Over more than two decades, CYCT has built a reputation for excellence, serving as a critical infrastructure partner for oil, gas, chemical, municipal water, and petrochemical industries.
We maintain deep, strategic partnerships with leading petrochemical laboratories, including the CNPC Pipeline Science Research Institute. This collaborative framework ensures that our material chemistry is tailored directly to combat the most extreme field installation conditions. From high-integrity offshore field joint systems to localized trenchless rehabilitation solutions, CYCT delivers field-tested systems certified to meet ISO, DIN, and NACE/AMPP requirements.
Industrial Endorsement:
Stable supplier of PetroChina, Sinopec, PipeChina, China Gas Group, and Indian Oil Corporation, supporting major energy pipeline schemes across multiple continents.
Mitigating the multibillion-dollar challenge of global asset degradation and mechanical wear
Cross-country pipeline networks require reliable coating systems at weld joints to prevent stress corrosion cracking (SCC) and localized mechanical disbondment. Our PP and PE heat-shrinkable materials deliver robust barrier properties.
Horizontal Directional Drilling (HDD) exposes coatings to high shear forces, friction, and rocky substrates. Our Epoxy Fiberglass Reinforced Plastic (FRP) and fiberglass-reinforced wraps shield pipelines during pull-back operations.
Valves, tees, and complex fittings present challenging profiles. Our viscoelastic coatings flow into recesses to eliminate air pockets, creating a self-healing barrier against corrosive factors.
A deep dive into CYCT's material formulations and mechanical capabilities
CYCT's heat-shrinkable sleeves and tapes are formulated from radiation-crosslinked high-density polyethylene (HDPE) or modified polypropylene (PP) backing layers. These are coated with a hot-melt copolymer adhesive.
• Peel Strength to Steel: >80 N/cm at 23°C (DIN 30672)
• Thermal Aging Life: Over 50 years under standard operating conditions
• Shrinkage Ratio: ≥30% radial shrinkage for a tight conformable seal
This technology is optimized for both 2LPE and 3LPE/3LPP configurations, protecting cutback areas at girth welds during field joint coating (FJC) operations.
Our viscoelastic systems leverage non-crystalline low-molecular-weight polyolefins that maintain viscous flow characteristics throughout their design life. These coatings flow into irregularities on the substrate, offering excellent wetting properties.
• Operating Temperature: FVT95 operates stably up to 95°C
• Water Vapor Permeability: < 0.1 g/m²/24h
• Self-Healing: Automatically fills minor mechanical pinholes and micro-fractures
Viscoelastic wraps eliminate the need for primers, reducing installation time while providing robust protection against water and oxygen ingress.
Quality assurance at CYCT is managed by our CNAS-accredited national laboratory. This in-house facility runs continuous testing protocols to evaluate peel strength, shear resistance, impact resistance, and cathodic disbondment.
We operate automated extrusion lines, radiation crosslinking chambers, and adhesive coating units. This vertical integration allows us to customize product parameters—such as thickness, width, and polymer chemistry—to meet project-specific engineering standards.
Raw Material Traceability
Quality Management
Extending support beyond factory output to ensure high-quality on-site application
We offer specialized detection services for existing buried networks. Using advanced electromagnetic technology, our engineers locate coating defects, evaluate cathodic protection status, and map sub-surface pipeline paths without requiring excavation.
Aging infrastructure requires specialized solutions. CYCT works with asset owners to design rehabilitation schemes, selecting optimized combinations of viscoelastic tapes, mastic fillers, and outer wraps to restore integrity while minimizing downtime.
Even high-quality coating materials can fail if applied incorrectly. Our field service technicians provide on-site pre-heating supervision, application monitoring, and holiday detection verification to ensure long-term performance.
