Explore our high-performance pipeline joint protection materials, custom-formulated and manufactured to meet major international standards.
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 service and pipeline coating field application service into one. CYCT devotes itself to R&D, production and sales of pipeline corrosion protection materials for decades.
By establishing deep cooperation with leading R&D institutes such as CNPC Pipeline Science Research Institute, CYCT is capable of providing in-service pipelines with varied technical services such as buried pipeline detection, design scheme development, cathodic protection, rehabilitation project design, and an integrated system solution for pipeline lifetime safety.
CYCT has become a stable supplier of field joint coatings for years in major state enterprises including PetroChina, Sinopec, PipeChina, and regional pipeline grids, holding an exceptionally high market share. Furthermore, CYCT has successfully developed and introduced a number of specialty corrosion protection materials such as visco-elastic anticorrosion materials, special photo-curing sleeves for Horizontal Directional Drilling (HDD) protection, and high-build polyurea coatings.
Analyzing modern market forces, stringent environmental guidelines, and the growing demand for high-strength field joint protection.
High-pressure oil and gas pipelines represent the circulatory system of modern industry. Over 40% of critical pipeline failures originate from field joint degradation. As long-distance transmission networks span across increasingly hostile geographies, project owners and EPC contractors require heat shrink pipe sleeves that offer superior thermal stability, shear resistance, and structural integrity under high soil stress conditions.
Our OEM manufacturing process addresses these concerns by producing heavy-duty, radiation cross-linked high-density polyethylene (HDPE) backings combined with premium mastic or hot-melt adhesives. These custom solutions ensure zero moisture ingress, minimizing the risk of cathodic disbondment and galvanic corrosion.
Historically, pipeline protection relied on cold-applied wraps or simple PVC protective tapes. Today, global standards such as ISO 21809-3 Type 14B and 14C and EN 12068 dictate the use of advanced heat shrinkable sleeves (HSS) with solvent-free liquid epoxy primers. This 3-layer configuration provides the ultimate barrier against chemical attack and mechanical shear.
By transitioning to high-expansion-ratio PE sleeves, modern pipeline rehabilitation projects optimize application times while guaranteeing thick, uniform coverage that adheres seamlessly to both factory-applied 3LPE/3LPP coatings and bare steel joints.
How our localized pipeline protective solutions adapt to diverse soil characteristics, temperature ranges, and installation challenges worldwide.
For offshore platforms, subsea pipelines, and riser protection, moisture ingress and mechanical wear from wave action pose constant risks. Our specialized GRF Moisture Curing Shield provides structural reinforcement, resisting marine environments, saltwater spray, and high mechanical abrasion.
In hot desert regions, pipelines run under high operational temperatures, subject to continuous soil expansion and contraction. We provide high-temperature heat shrinkable sleeves (such as our FRDP 60C and 3LPP-compatible systems) that prevent shear displacement and remain chemically stable up to 80°C.
Horizontal Directional Drilling (HDD) exposes field joint coatings to extreme shear forces as the pipe is pulled through rock and compacted soil. CYCT's specialty photo-curing sleeves and fiber-reinforced mechanical wraps form an impenetrable outer shield, preventing peel-back and scraping during pullback.
Our commitment to advancing raw material chemistry, radiation cross-linking techniques, and green manufacturing.
Eliminating volatile organic compounds (VOCs) during on-site field joint preparation. Our solvent-free epoxy primers guarantee robust chemical bonding without environmental or installer health hazards.
Integrating viscoelastic materials with cold-flow properties, ensuring the compound flows into microscopic metal crevices to self-heal minor installation defects and resist cathodic disbondment.
Refining electron-beam (E-beam) dosage during backing manufacture, providing uniform molecular cross-linking for consistent heat shrink recovery and optimum physical strength.
We are currently researching the integration of sensing materials and passive RFID indicators into the polyolefin backing. This technology will allow pipeline operators to assess joint temperature, coating pressure, and moisture intrusion remotely using non-destructive inspection tools, reducing overall maintenance overhead.
Combining structural cost advantages with strict QA oversight to secure stable global logistics for large-scale energy projects.
CYCT's production site leverages China's industrial clusters. We maintain direct partnerships with leading polymer manufacturers, securing supply during market fluctuations. Our plant houses high-capacity extruders, compound mixers, and automated electron-beam radiation cross-linking units. This vertical integration allows us to customize backing thicknesses, width specifications, and adhesive weights without relying on third-party processors, cutting delivery lead times by up to 35% compared to Western suppliers.
Our proximity to major ports (such as Shenzhen and Shanghai) ensures swift dispatch of sea containers. We maintain a permanent stock of standard-size heat shrink sleeves (FRDP 60C, viscoelastic tapes, and repair sticks) for emergency pipeline repair orders. For large pipeline bids, our logistics coordinators manage complex shipments, supply tracking, custom declaration documents, and local compliance paperwork, ensuring deliveries arrive on-site ahead of schedule.
CYCT is committed to maintaining international certifications, technical transparency, and support for engineering contractors.
Operating a national CNAS-accredited laboratory, CYCT subjects every production batch to rigorous checks, including differential scanning calorimetry (DSC) tests, peel strength assays, and thermal aging evaluations. We are an active council member of the Chinese Society for Corrosion and Protection (CSCP) and AMPP (Association for Materials Protection and Performance), adhering to global corrosion standards.
Our project credentials span multiple continents, supplying critical anti-corrosion materials to pipeline giants like PetroChina, Sinopec, China Gas Group, and Indian Oil. Whether you require custom dimensions (OEM) or standardized heat-shrink sleeves, our global technical sales engineers provide support, installation training, and on-site guidance.
