Pioneering pipeline joint materials engineered in our CNAS-accredited laboratory to meet global ISO and NACE standards.
In modern pipeline infrastructure networks—spanning thousands of kilometers across extreme geographical terrains and harsh environment conditions—the prevention of corrosion is paramount. Standard raw steel is highly susceptible to electrochemical attack, necessitating complex, multi-layer coating systems. As a leading OEM Adhesive Epoxy Manufacturer and Factory, our core expertise lies in addressing the vulnerable interfaces of these pipelines: the field joint coatings, directional drills, and structural repair sectors.
Adhesive epoxies act as the essential bonding agent, bridging steel surfaces with outer protective polymeric layers (such as Polypropylene and Polyethylene). Without a high-performance solvent-free liquid epoxy primer, the chemical and physical bonds degrade over time under the influence of soil stress, moisture penetration, and thermal expansion. Our engineered formulations are designed to maintain integrity across high-temperature operational thresholds, preventing cathodic disbondment and ensuring that structural integrity is sustained over design lives exceeding 30 years.
Standard adhesive epoxy formulations often fail under specialized operational stresses. Customization allows us to tailor critical chemical indexes: glass transition temperature (Tg), viscosity indicators for uniform wetting, curing kinetics matching regional ambient profiles, and molecular structures resilient against cathodic disbondment stresses. Our state-level high-tech chemical synthesis plant addresses these performance properties directly, supporting international specifications such as ISO 21809-1 and 21809-3.
Global procurement teams from leading corporations such as PetroChina, Sinopec, PipeChina, and Indian Oil demand more than off-the-shelf industrial polymers. They require validated testing configurations, extensive compliance certificates, and factories capable of high-throughput capacity with guaranteed batch-to-batch consistency. In critical pipeline asset management, procuring materials without verified chemical validation introduces multi-million dollar liability risks.
To assure procurement officers of zero-risk sourcing, our factory operates advanced quality management programs. Every delivery of Solvent-free Epoxy Primers, PP Hot Melt Sticks, and Viscoelastic Anti-corrosion Tapes undergoes rigorous non-destructive and destructive assessments. Our national CNAS-accredited laboratory carries out testing covering cathodic disbondment resistance, peel strength assays on steel and polyolefin backings, impact resistance, and long-term hot-water immersion tests. This ensures our materials maintain peak performance properties even in sub-zero or high-humidity tropical application environments.
Company Profile
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 services and pipeline coating field application services 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 maintaining close technical collaboration with leading research institutes such as the CNPC Pipeline Science Research Institute, CYCT is capable of providing in-service pipelines with varied technical services including buried pipeline detection, bespoke design schemes, cathodic protection integration, rehabilitation project management, and integrated safety protection solutions for energy transmission networks.
CYCT has become a stable supplier of field joint coatings for years to PetroChina, Sinopec, PipeChina, and various local pipeline operators, securing a commanding 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 advanced polyurea coatings.
We are a recognized Member of the Council in the Chinese Society for Corrosion and Protection (CSCP), holding Qualification Certificates of Corrosion Protection Construction and Pipeline Detection. Recognized as a Well-known Brand of Pipeline Corrosion Protection in China, and a Corporate Member of the China Association of Petroleum Engineering Construction (CAPEC), CYCT serves as a qualified supplier to PetroChina, Sinopec, China Gas Group, and Indian Oil.
Pipelines traverse complex and diverse geographics, demanding distinct, project-specific protective systems. CYCT provides targeted architectural designs to mitigate structural failure risk across various field environments:
For Horizontal Directional Drilling (HDD), shear stress and abrasive forces can strip standard pipeline coatings. Our heat shrinkable fiberglass reinforced sleeves utilize high-tensile glass fibers integrated within polymer matrices to resist mechanical abrasion during pull-through operations.
Operating temperatures exceeding 100°C trigger degradation of standard adhesives. We formulate specialized high-temperature PP hot melt adhesives and FRPD-PP sleeves to match factory polypropylene linepipe joint standards, preventing delamination.
For operational lines undergoing repairs, we offer FVT95 fabric viscoelastic tape, VE Putty, and repair patches. These systems allow fast field application with minimal substrate preparation, restoring full system protection quickly.

Pipeline installation is highly time-sensitive, where execution delays incur substantial capital penalties. As an experienced OEM factory partner, CYCT delivers integrated field support alongside material manufacturing. We support regional EPC (Engineering, Procurement, and Construction) companies by providing field coating application services, on-site testing equipment verification, and technical training programs for coating installers.
This localized field support ensures materials are applied within specified technical margins, eliminating risks related to incorrect surface profiling (SA 2.5 preparation) or thermal application errors. Our international certificates allow seamless compliance checks across diverse regulatory jurisdictions:
As pipeline operators encounter more extreme development zones—such as deep-water offshore trenches, Arctic transport routes, and geothermal fields—standard polymer chemistries face physical limitations. At CYCT, our engineering teams are developing next-generation protection technologies:
Developing ultra-high thermal resistance primers capable of maintaining chemical stability at sustained temperatures up to 150°C. These systems address demanding thermal profiles in heavy crude transmission networks.
Advancing green formulations, such as non-toxic, water-resistant VE Putty and low-VOC liquid epoxies, to support strict global environmental and health regulations.
Integrating microencapsulated polymer matrices that rupture to seal micro-cracks under localized stress, alongside sensor-compatible coating layers to provide real-time corrosion alerts.
A full range of specialized tapes, patches, and structural repair components designed for modern pipeline integrity.
