Explore our industrial-grade, certified anti-corrosion tapes, patches, and sleeves designed for extreme environments.
Modern energy infrastructure, municipal networks, and chemical transmission lines rely heavily on underground steel pipelines. Left unprotected, these pipelines suffer from aggressive soil-induced electrochemical corrosion, mechanical damage during compaction, and cyclic thermal stress. High-performance field joint coatings (FJC) and repair solutions are the critical defense mechanism protecting global industrial pipelines.
Our specialized OEM Coatings Applications are engineered to address the core challenges of modern pipeline construction: seamless adhesion, robust thermal stability, excellent cathodic disbondment resistance, and long-term chemical isolation. By leveraging advanced polymeric science, we manufacture viscoelastic matrices, radiation-crosslinked polyolefin heat shrink materials, and custom hot-melt adhesives designed to match factory-applied parent coatings like 3-Layer Polyethylene (3LPE) and 3-Layer Polypropylene (3LPP).
As a dedicated OEM/ODM manufacturer, we work closely with design institutes, procurement directors, and EPC contractors to produce tailored, highly compliant pipeline field joint protection materials that exceed international standards.
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. Our state-of-the-art testing systems analyze polymer rheology, mechanical shear, peel strength, thermal degradation, and cathodic disbondment to ensure every batch of materials shipped to global project sites exhibits flawless consistency.
Over the years, CYCT has become a stable supplier of field joint coating for PetroChina, Sinopec, PipeChina and local pipelines, capturing an exceptional 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 Horizontal Directional Drilling (HDD) protection, and polyurea coating.
By good cooperation with leading R&D institutes such as CNPC Pipeline Science Research Institute, CYCT is capable of providing in-service pipelines with varied technical services such as buried pipeline detection, design schemes, cathodic protection, rehabilitation projects, and an integrated solution for the safety protection of pipelines.
Unlocking operational efficiency, high-volume consistency, and raw material integration for global clients.
Benefiting from direct integration with the world's largest petrochemical refining clusters in China, we source premium grades of Polyethylene, Polypropylene, EPDM, and specialty elastomer resins at optimized costs, insulating clients from severe market fluctuations.
Our facility runs state-of-the-art co-extrusion production lines that maintain strict dimensional controls and uniform adhesive distribution, assuring consistent thickness and zero delamination risks for field-applied sleeves and patches.
We configure custom parameters, private-label packaging, and specified roll lengths to perfectly support local field operators, ensuring that field installation speeds and product application metrics are fully optimized.
Procuring anti-corrosion systems for mega-projects requires strict compliance, regulatory documentation, and logistical support. CYCT bridges the gap between high-volume manufacturing capabilities and site-specific localized needs.
Whether your project requires conformity to EN 12068 (standards for organic coatings for cathodic protection), ISO 21809-3 (field joint coatings for pipeline transportation), or NACE/AMPP SP0169 standards, CYCT provides verified documentation, complete material test reports (MTRs), and certifications for each batch.
For overseas projects in the Middle East, Central Asia, South America, and Europe, we provide specialized export packaging, moisture-barrier wrapping, and temperature-controlled logistics, ensuring that field-applied tapes, fillers, and sleeves arrive at site with active chemical adhesion properties fully intact.
Our technical engineers provide 24/7 technical advice, detailing optimal surface preparation (ISO 8501-1 Sa 2½ blast clean standards), heat preheat parameters, and post-application testing procedures.

Adapting pipeline joint protection materials to harsh geologic conditions and emerging green technology standards.
For trenchless piping passing under rivers, highways, or urban segments, standard coatings face intense shear force. CYCT's special photo-curing sleeve acts as a sacrificial, high-hardness protective mechanical shield over anti-corrosion layers, ensuring zero delamination during pull-back operations.
As deep wells and geothermal oil transport systems reach operating temperatures up to 80°C - 110°C, traditional polyethylene backing degrades or flows away. CYCT's FRPD-PP heat shrinkable sleeves utilize radiation-crosslinked polypropylene matrices capable of enduring extreme, long-term thermal loads.
In municipal valve chambers, flanges, and complex-shaped pipeline geometries, standard wrapping is highly susceptible to voids. FVT95 Fabric Viscoelastic Tape offers a cold-flowing compound that remains fluidic, flowing into micro-gaps and naturally sealing physical impacts automatically.
Direct technical answers addressing the key procurement, application, and compliance needs of global field engineers.
3LPE (3-Layer Polyethylene) is generally rated for maximum service temperatures up to 80°C. For pipelines carrying highly viscous crude oil at elevated temperatures, 3LPP (3-Layer Polypropylene) is utilized, allowing operation up to 110°C. Repairs must match the parent coating. For 3LPE, PE repair patches (like FRDX) or mastic tapes are suitable. For 3LPP, PP hot melt sticks or specialized PP-backed heat shrinkable sleeves are mandatory to maintain chemical and thermal compatibility.
Viscoelastic materials (such as CYCT FVT95 Fabric Viscoelastic Tape) are made from non-crystalline, low-molecular-weight polyisobutylene (PIB) compounds. This unique chemical structure exhibits dual properties: the viscosity of a fluid and the elasticity of a solid. Under soil pressure or mechanical stress, the material behaves like a high-viscosity fluid, slowly flowing into surface micro-roughness, microscopic voids, and mechanical damage, maintaining continuous moisture isolation.
For maximum performance, the steel joint area must be abrasive blast-cleaned to a minimum standard of Sa 2½ (ISO 8501-1) with a surface profile anchor pattern of 50-85 μm. All moisture, grease, and mill scale must be completely removed. Prior to installing the heat shrinkable sleeve, the steel substrate must be preheated using an induction coil or propane torch to the specified temperature (often between 60°C and 80°C depending on the adhesive system) to ensure immediate adhesive melt and void-free bonding.
During HDD operations, the pipeline is pulled through a pre-drilled borehole. The friction against rocks, sand, and subterranean debris can tear traditional polymer coatings. A photo-curing sleeve, constructed from fiberglass reinforced plastic (FRP), is wrapped over the primary anti-corrosion coating (such as viscoelastic tape or heat shrink sleeve). Upon exposure to UV radiation (sunlight or artificial lamps), the polymer cures rapidly into a high-strength, hard shell that absorbs mechanical shear and impact, protecting the underlying barrier.
Yes, CYCT is a dedicated OEM Coatings Applications factory. We customize backing thicknesses (from 1.0mm to 3.0mm), adhesive widths, release liner split configurations, custom packaging boxes, and private labeling. We also adjust polymer formulations (viscoelastic or hot-melt) to match specific regional thermal and environmental challenges.
