Explore our elite range of factory-direct field joint protection solutions and high-temperature heat shrinkable tubular sleeves.
Within modern industrial pipeline infrastructures, ensuring reliable corrosion protection and insulation is paramount. Heat shrinkable tubes, field joint sleeves, and repair systems stand at the vanguard of this engineering frontier. Primarily manufactured using radiation-crosslinked polyolefins (such as PE or PP) or advanced polyester (PET) formulations, these materials offer outstanding mechanical protection and environmental sealing.
The manufacturing process relies on polymer modification. By subjecting high-grade Polyethylene (PE) or Polypropylene (PP) to precise electron-beam radiation, carbon-carbon molecular cross-linking is established. This process alters the polymer from a thermoplastic structure to a thermoset elastomer possessing "elastic memory." When heated beyond its crystalline melting point during application, the material shrinks radially, applying continuous compressive pressure to the substrate. Coupled with high-performance hot-melt co-polymer adhesives or viscoelastic mastics, this forms an impenetrable barrier against moisture, oxygen, and corrosive chemicals.
Chinese factories, particularly industry leaders like CYCT, have elevated manufacturing protocols by incorporating state-of-the-art co-extrusion technology, raw material modification, and CNAS-approved verification laboratories. This vertical integration allows for customized shrink ratios, optimized adhesive shear resistance, and excellent cathodic disbondment mitigation, conforming strictly to ISO 21809-3 and EN 12068 standards.
A pioneering authority in pipeline corrosion protection, established in 2000.
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 setup ensures that every batch of heat shrinkable sleeves, viscoelastic tapes, and repair patches meets standard tolerances and undergoes thorough thermal aging and chemical resistance validation.
Over the years, CYCT has become a stable supplier of field joint coatings for PetroChina, Sinopec, PipeChina, China Gas Group, and Indian Oil, holding a dominant 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 HDD protection, and polyurea coatings.
