Direct supply from state-of-the-art Chinese manufacturing facilities. Engineering-grade anticorrosive tapes and specialty repair systems certified to international quality standards.
Uncompromising environmental stressors demand advanced materials engineered to eliminate localized corrosion, cathodic disbondment, and biological deterioration.
Underground pipelines undergo cyclic mechanical motion due to seasonal thermal expansion. In cohesive clay soils, this exerts enormous sheer force (soil stress) on external coatings. Modern cold-applied tapes must possess superior backing strength and viscoelastic characteristics to resist sliding deformation.
Traditional solid-film plastic backings can shield the pipe from cathodic protection (CP) current if moisture penetrates the adhesive layer, accelerating corrosion beneath the tape. CYCT develops advanced mesh-reinforced viscoelastic formulations that allow CP current permeability, preventing catastrophic pitting.
Crude oil and natural gas flow at high operational temperatures (sometimes exceeding 80°C). Coatings must endure these conditions without softening, melting, or peeling. Polypropylene (PP) outer tapes and specialized high-temp hot melt sticks guarantee stability in demanding global regions.
A national-level pioneer in polymeric new materials and infrastructure safety diagnostics.
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.
CYCT owns leading testing and R&D capabilities, a professional R&D team, and a national CNAS-accredited laboratory. This credentials our facility to perform testing for tensile strength, elongation at break, peel strength, shear resistance, impact resistance, and cathodic disbondment under extreme conditions, adhering strictly to global standards.
CYCT becomes the stable supplier of field joint coating for years in PetroChina, Sinopec, PipeChina and local pipelines and holds a very 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 sleeve for HDD protection and polyurea coating.
By good cooperation with leading R&D institutes such as CNPC Pipeline Science Research Institute, CYCT is capable to provide in-service pipelines with varied technical services such as buried pipeline detection, design scheme, cathodic protection, rehabilitation project and an integrated solution for the safety protection of pipelines.
A comprehensive roadmap highlighting the evolution of materials from cold-applied PE tapes to self-healing viscoelastic polymers.
Operating on the principle of liquid-like cold flow behavior with solid-like elasticity. Viscoelastic tapes (such as FVT95) self-heal micro-defects and exhibit complete intimate contact with steel substrates, preventing under-film moisture migration.
Radiation cross-linked polyolefin backings with advanced structural memory. When heated, the material shrinks to form a tight casing while the internal hot-melt copolymer adhesive flows into every surface profile, matching 3LPE/3LPP configurations.
Glass Fiber Reinforced Polymers (GFRP) provide structural restoration of metal loss in operating lines. By avoiding pipe shutdown or hot work, GFRP systems arrest structural decay and restore pressure ratings economically.
How pipeline corrosion protection tape systems are customized to perform under varying geographical conditions across the globe.
In arid regions like the Middle East or Western China, pipeline coatings face soil temperatures exceeding 60°C and severe mechanical shear from windblown sand. Our PP high-temperature outer tape combined with FRDX hot melt filler prevents shifting and ensures high thermal stability.
Cold applied PE tapes are essential in sub-arctic regions where hot coatings crack upon cooling. Viscoelastic tapes remain flexible and soft down to -40°C, maintaining intimate bond strength with structural metal even without primer pre-heating.
Horizontal Directional Drilling (HDD) subjects the outer pipeline coating to high shear from gravel, rock, and mud. Standard PE or PP tape is reinforced with specialized photo-curing sleeves or GFRP composite shields to prevent gouging during pulling operations.
Corrosion rates are highest in splash zones with fluctuating salinity, humidity, and oxygenation. Utilizing viscoelastic paste (VE Putty) combined with viscoelastic tape wrapping prevents pitting at irregular flanges, valves, and field joints.
Leveraging continuous raw monomer sourcing, fully automated production runs, and global logistics corridors.
Located close to major petrochemical manufacturing clusters in China, CYCT enjoys highly stable sourcing of premium polypropylene (PP), polyethylene (PE), and synthetic elastomers, shielding clients from global raw material price shocks.
Collaborating with institutions like the CNPC Pipeline Science Research Institute, CYCT ensures that every production batch meets rigorous ASTM D1000, EN 12068, and ISO 21809-3 specifications.
Fully integrated extrusion, coating, adhesive formulation, and packaging lines mean CYCT optimizes labor and overhead costs, providing up to 25% CapEx savings on large-scale infrastructure purchases.
