Modern industrial pipeline networks constitute the critical infrastructure of the global energy and utility sectors. Maintaining the structural integrity of these underground and subsea lines requires sophisticated, long-term engineering methods. Corrosion remains the primary catalyst for pipeline degradation, costing industries billions in annual remediation. To combat this, advanced pipeline field joint coating (FJC) systems have evolved from simple tar wraps to highly specialized polymer structures including cross-linked high-density polyethylene (HDPE), viscoelastic matrix polymers, and high-strength copolymer hot-melt adhesives.
As a leading OEM Adhesive Heat Shrink Manufacturer, CYCT delivers advanced engineering materials that resolve the classic failure points of field joints: moisture penetration, cathodic disbondment, mechanical impact during backfilling, and soil stress. By leveraging polymer chemistry, radiation cross-linking technology, and formulation sciences, we manufacture products that ensure joint coatings remain intact under extreme pressures and wide operating temperature ranges.
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. By partnering closely with leading industrial research institutes, we continuously refine our polymer cross-linking techniques and structural heat-shrink formulations.
CYCT has been a 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 coatings.
Our OEM heat shrinkable sleeves utilize advanced copolymer adhesives formulated to bind securely with mill-applied PE and PP coatings. The thermal shear resistance guarantees zero slippage under extreme axial soil stresses, maintaining bond line thickness and moisture-barrier continuity.
Viscoelastic coating systems feature cold-flow properties, providing complete wetting of the substrate steel. Even if subjected to mechanical impacts, the adhesive exhibits viscous flow, sealing scratches and minor abrasions autonomously to prevent localized galvanic corrosion.
For Horizontal Directional Drilling (HDD) and high-load offshore operations, standard sleeves run the risk of tearing. Our glass fiber reinforced designs provide high tensile strength, exceptional puncture resistance, and heavy mechanical protection against rocky backfills.
Global pipeline projects operate on tight timelines and budgets. Choosing CYCT as your OEM manufacturing partner in China provides access to a highly integrated, reliable industrial supply chain designed to support large-scale infrastructure projects:
Our facility is located in China's advanced polymer industrial zone, securing direct supply lines for high-quality polyolefin resins, specialized elastomers, and custom cross-linking agents. This integration insulates our pricing from global raw material volatility and guarantees continuous production capacity.
Operating modern wide-width extrusion and compounding lines, CYCT can supply large orders for pipelines exceeding DN2000 in diameter. We scale production rapidly to align with high-demand project milestones, minimizing container lead times.
Our national CNAS-accredited testing facility conducts comprehensive checks on raw materials and finished goods, including peel strength tests, cathodic disbondment assessments, heat shock tests, and differential scanning calorimetry (DSC) analysis to ensure strict standard compliance.
Global engineering, procurement, and construction (EPC) contractors require partner flexibility. A single product line cannot fit all environmental conditions. A pipeline in the Siberian tundra requires different backing flexibility and adhesive flow rates than a gas transmission line in the Arabian desert.
At CYCT, our engineering team works with client specifications to adjust:
By collaborating with leading R&D institutes such as the CNPC Pipeline Science Research Institute, CYCT provides in-service pipelines with varied technical services, including buried pipeline detection, design scheme creation, cathodic protection analysis, rehabilitation project support, and integrated pipeline safety solutions.
Anti-corrosion integrity depends as much on correct field installation as it does on factory manufacturing. If an installer applies a heat shrink sleeve to a wet or poorly pre-heated pipe, the adhesive bond will fail. CYCT provides training programs, field service support, and technical installation guides translated into multiple languages to help field crews maintain standard operating procedures.
Moreover, compliance with national energy regulatory bodies is a prerequisite for oil and gas projects. CYCT holds a comprehensive suite of quality, environmental, and occupational health certifications, and maintains active corporate membership in international bodies like the Association for Materials Protection and Performance (AMPP) to keep pace with changing standards.
CYCT materials are designed to perform reliably across a wide range of pipeline environments:
During pull-back operations, pipelines face extreme abrasion and shear forces against the borehole wall. Standard field joint wraps can tear or peel away. Our FRDP Heat Shrinkable Fiberglass Reinforced Sleeves are engineered to withstand these mechanical forces, keeping the underlying steel pipe protected throughout the pull-back process.
Marine environments present severe corrosion risks due to constant moisture and high salinity. The CYG Changtong GRF Moisture Curing Shield acts as a robust barrier for subsea and splash zone lines, curing in water to form a durable protective composite layer that resists waves, salts, and tidal forces.
Underground municipal utility networks need cost-effective, long-lasting anti-corrosion protection. CYCT's non-toxic VE Putty and viscoelastic tapes conform easily to complex valves, tees, and flanges, sealing against water ingress without requiring specialized application equipment.
CYCT is a Council Member of the Chinese Society for Corrosion and Protection (CSCP), holds Qualification Certificates for Corrosion Protection Construction and Pipeline Detection, and is recognized as a Well-known Brand of Pipeline Corrosion Protection in China. We are an active corporate member of the China Association of Petroleum Engineering Construction (CAPEC) and a State-Level High-Tech Enterprise with more than ten proprietary intellectual property rights.
