Explore our industrial-grade protective coatings, high-performance shrinkable sleeves, and custom viscoelastic solutions engineered for extreme environments.
Buried and offshore pipeline infrastructure undergoes continuous stress from soil settlement, moisture, chemical infiltration, and thermal fluctuation. To prevent catastrophic failure, engineers depend on high-performance coatings. Under the 3-Layer Polyethylene (3LPE) configuration, protective tape operates as a robust barrier system composed of a liquid epoxy primer, a copolymer hot-melt adhesive, and a radiation cross-linked high-density polyethylene (HDPE) backing.
When heated, the heavy-duty backing shrinks, creating a radial compression force that drives the molten adhesive layer into every crevice of the steel substrate. The epoxy primer establishes a chemical bond directly with the sandblasted steel surface, eliminating the risk of cathodic disbondment. This configuration provides a continuous, impervious shield against moisture ingress, aggressive soils, and mechanical wear during backfilling.
Radiation-induced polymer cross-linking yields high dimensional stability, memory effect during thermal shrinkage, and outstanding resistance to abrasion, puncture, and soil stress.
Specially formulated adhesive flows under installation heat to bond with the epoxy primer and pipe surface, preventing moisture pathways and resisting high shear loads.
Integrates with liquid epoxy systems to protect against environmental degradation, maintaining structural integrity across decades of buried service.

CYCT maintains testing and R&D capabilities, supported by a professional engineering team and a national CNAS-accredited laboratory, ensuring batch-to-batch quality and compliance with global pipeline standards.
Why pipeline developers and EPC contractors depend on CYCT's integrated manufacturing ecosystem in China.
Our long-term partnerships with leading polymer and petrochemical providers secure stable pricing and consistent supply, even during volatile global market shifts. This ensures project schedules remain uninterrupted.
Equipped with advanced extrusion, cross-linking, and adhesive coating lines, CYCT manages high-volume production requests with short lead times, handling large-scale oil and gas pipeline orders efficiently.
Every step, from resin blending to final packaging, is monitored under ISO 9001 and ISO 14001 structures. Certified inspectors in our CNAS laboratory conduct peel tests, thermal aging, and thickness verification for every batch.
Managing cross-border procurement requires alignment with local regulations, industry standards, and customs logistics. CYCT provides comprehensive documentation support, including Mill Test Certificates (MTC), third-party inspection compliance (SGS, BV), and compliance tracking.
Our pipeline products conform to international anti-corrosion specifications, including ISO 21809-3, EN 12068, ASTM D638, and DIN 30670. This compatibility makes them suitable for global EPC contractors, gas utilities, and industrial pipeline operators.
CYCT also provides onsite field joint coating (FJC) training, installation guides, and customized rolls or sleeves to fit specific pipe diameters, coating thicknesses, and environmental requirements.
CYCT is recognized for technical innovation and product safety:
Where science meets reliability: Innovations shaping the future of anti-corrosion applications.
Transitioning away from heavy solvents, modern formulations employ low-VOC, high-stability polymers. These compounds meet stringent international environmental regulations without compromising bond strength.
Deep-well systems and specialized processes operate at elevated fluid temperatures. Advanced polymers are designed to withstand operating heats up to 110°C without sliding or peeling.
Integrating taggants and tracer layers into the backing allows inspection teams to verify installation quality and trace production batches in the field using handheld scanners.
Our materials are configured to handle diverse geologic and climatic environments.
Pulling pipes through boreholes exposes field joints to severe shear and abrasive forces. CYCT's specialized photocuring GRP sleeves and epoxy FRP protectors wrap around joint areas, shielding them during pull-back operations.
Offshore environments demand high resistance to saltwater exposure. Our PP heat shrink sleeves and viscoelastic tapes provide continuous sealing under high hydrostatic pressures.
High sand temperatures require stable, non-sagging adhesives. Our wide-temperature viscoelastic systems retain bond strength, resisting UV degradation in open and shallow-trench pipelines.

Detailed answers to help engineers and procurement managers evaluate pipeline protection products.
A 3LPE (3-Layer Polyethylene) system includes a liquid epoxy primer applied directly to the bare, sandblasted steel substrate, followed by the copolymer adhesive and the radiation cross-linked polyethylene backing. Standard 2LPE systems omit the epoxy primer layer. The inclusion of the epoxy primer in 3LPE provides superior resistance to cathodic disbondment and improves overall peel strength, making it the preferred choice for high-integrity transmission pipelines.
Yes. We routinely work with international inspection bodies, including SGS, Bureau Veritas (BV), and Intertek. We arrange and document pre-shipment testing at our CNAS-accredited laboratory or raw material verification to ensure all items align with your project's technical specifications.
The tape width is typically selected based on the nominal pipe diameter and the width of the cutback area, ensuring an overlap of at least 50mm onto the factory-applied line coating on both sides of the joint. The required thickness depends on environmental conditions and project specifications, typically ranging from 1.8mm to 3.2mm. Our engineers help optimize these dimensions based on your specific project parameters.
According to standard guidelines (e.g., ISO 21809-3), the steel surface must be abrasive blasted to a minimum near-white metal finish (Sa 2.5) with a rough surface profile (typically 50-90 microns). The adjacent factory-applied coating must be beveled and abraded to ensure a strong, uniform bond at the overlap zones. The pipe surface is then pre-heated to the recommended temperature before primer application.
When stored in a dry, ventilated warehouse at temperatures below 35°C and kept away from direct sunlight, our heat shrinkable sleeves and viscoelastic tapes have a shelf life of up to 2 years from the date of manufacture.
