Explore our industry-validated range of field joint coatings, high-performance polymeric sleeves, and heavy-duty pipeline protection systems.
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. Our scope of work encompasses buried pipeline detection services, pipeline coating field application service, and high-performance crosslinked thermal polymers.
For decades, CYCT has dedicated itself to the design and refinement of specialized polymer formulations. Through robust partnerships with top-tier research institutes, such as the CNPC Pipeline Science Research Institute, CYCT delivers turnkey integrated solutions for energy networks globally.
CYCT operates leading-edge test facilities, advanced extrusion lines, and a national CNAS-accredited research lab.
As global energy networks expand, the demand for highly reliable joint coatings has surged. China has evolved from a high-volume manufacturing center into the global technological hub for polymer cross-linking technology.
The manufacturing process of high-quality heat shrink tubes—such as our FRPD-PP heat shrinkable sleeves—requires precise control over polymer physics. By utilizing advanced high-energy electron accelerators, we permanently alter the molecular structure of Polyethylene (PE) or Polypropylene (PP). This radiation cross-linking process establishes a molecular "memory" effect. When heated during field installations, the cross-linked polymers shrink uniformly, creating a high-stress, radial compression seal around pipeline joints.
Our raw material supply chain leverages localized high-grade olefin resins, optimized masterbatches, and shear-resistant hot melt adhesives. This vertical integration allows CYCT to maintain absolute consistency in thickness, backing density, and peel strength while remaining highly cost-competitive. Unlike regional distributors, our direct factory-to-site pipeline controls quality from initial compounding to final irradiation and adhesive coating.
Our custom PE and PP formulations deliver superior mechanical backing protection, high indentation resistance, and long-term thermal stability under continuous operational stresses.
Every production batch undergoes comprehensive evaluation within our national laboratory, ensuring compliance with international peel test, elongation, and shear-resistance criteria.
Engineered for trenchless pipeline installations, our Epoxy FRP and PP systems endure heavy axial drag forces during Horizontal Directional Drilling (HDD) pullbacks.
For global engineering procurement officers, compliance is paramount. Piping infrastructure in oil, gas, and chemical sectors must perform reliably for decades. Standardized heat shrinkable sleeves must satisfy stringent regulatory bodies before deployment.
At CYCT, our pipeline joint protection systems are manufactured to align with globally recognized codes:
Our status as an active council member of the Chinese Society for Corrosion and Protection (CSCP) underlines our dedication to cutting-edge material engineering, offering field engineers the confidence that our barrier coatings will prevent moisture ingress and soil stress failures.
Our systems hold major qualifications ensuring frictionless international custom clearance and engineering approvals:
Quality and Environmental Management Systems
Occupational Health & Safety Assurance
Validated National-Scale Independent Testing Lab
Our heat shrink sleeves, viscoelastic systems, and protective wraps are engineered for a diverse range of environmental challenges.
During Horizontal Directional Drilling (HDD), field joints encounter severe friction, shear force, and soil abrasion. Traditional shrink sleeves can roll back or peel off. Our Epoxy FRP (Fiberglass Reinforced Polymer) protective system forms a rigid structural shield over the primary joint coating, preventing damage during pipe pullbacks.
For modern electronic sub-assemblies, electric vehicle battery packs, and industrial capacitors, we supply high-performance PET Heat Shrink Tubes. Formulated from premium polyester, they offer exceptional dielectric strength, chemical resistance, and ultra-thin profile configurations to maximize space saving.
For high-operating-temperature gas networks, standard PE sleeves are unsuitable. Our FRPD-PP heat shrinkable sleeves are designed for factory-coated PP linepipe joints. Operating at elevated temperatures, they maintain strong mechanical adhesion and cathodic disbondment resistance.
As the pipeline industry moves toward safer, faster, and more environmentally friendly construction methods, CYCT is pioneering developments in smart materials.
Traditional PE shrink sleeves require pre-heating steel substrates to over 200°C. In challenging weather, maintaining this temperature is difficult and risks cold-joint failure. We are developing modified polymer backings that shrink effectively at lower pre-heat temperatures, saving energy and reducing installation errors.
By pairing cold-applied viscoelastic tapes, like our FVT95 Fabric Viscoelastic Tape, with rigid mechanical outer jackets, we offer dual-layer protection. The inner viscoelastic layer self-heals minor micro-cracks, while the outer shrink jacket provides high mechanical resistance.
For 3-layer PE (3LPE) joint configurations, our liquid epoxy primers are formulated without volatile organic compounds (VOCs). This ensures compliance with tight international environmental regulations while maintaining strong chemical bonding at the steel interface.
