State-Level High-Tech Enterprise | CNAS Laboratory Accredited Pipeline Field Joint Anticorrosion Systems
Explore our precision-engineered heat shrinkable sleeves, hot melt sticks, and anti-corrosive mastics manufactured in our state-of-the-art facility.
Long-distance pipelines traversing continents, extreme marine beds, and high-temperature geo-thermal terrains are the lifelines of the world's energy supply. However, the integrity of these networks is only as strong as their weakest links—specifically, the field weld joints. While factory-applied coatings (such as 3LPE or 3LPP) provide robust body protection, the welding of pipes in the field leaves bare steel joints vulnerable to rapid atmospheric and galvanic corrosion.
As a leading China Weld Joint Heat Shrink Sleeve Factory, CYCT delivers engineered solutions that restore continuous protection over these girth weld zones. Using high-performance irradiated cross-linked polyolefin backings paired with aggressive shear-resistant adhesives, our products prevent moisture ingress, resist soil stress, and withstand Cathodic Disbondment (CD).
EPC contracting companies, pipeline operators, and utility authorities face severe challenges: strict compliance with ISO 21809-3 standards, prompt logistics to remote sites, and long-term cost optimization.
CYCT's direct-factory supply model addresses these requirements by integrating design, rigorous raw material inspection, state-of-the-art radiation cross-linking machinery, and localized global support networks.
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.
For decades, CYCT has dedicated itself to the R&D and production of pipeline corrosion protection systems. Partnering with elite institutes like the CNPC Pipeline Science Research Institute, CYCT is capable of offering in-service pipelines comprehensive design schemes, cathodic protection, rehabilitation projects, and integrated security solutions.
Understanding structural layers and cross-linking chemistry is vital when selecting corrosion protection for critical pipeline infrastructure.
Consists of a liquid epoxy primer layer on the steel pipe, followed by a copolymeric hot melt adhesive interlayer, and topped with a high-density polyethylene (HDPE) or polypropylene (PP) backing. Protects joints in high soil stress and extreme temperatures.
Our PE and PP backings are modified via high-energy electron beam radiation. This creates covalent cross-link bonds between polymer chains, providing the "elastic memory" effect for quick heat recovery and shrinking.
From Viscoelastic Tape Systems with cold-flow self-healing capabilities to Photo-Curing GRP Protective Sleeves engineered for HDD (Horizontal Directional Drilling) trenchless pull-back protection.
CYCT has established direct material research operations with CNPC Pipeline Science Research Institute. The following gallery represents our production base, quality inspections, and advanced manufacturing platforms.
CYCT has established itself as an authoritative supplier to global oil and gas infrastructure organizations. Our credentials demonstrate our compliance and technical capability.
CYCT is a proud Council Member of the Chinese Society for Corrosion and Protection (CSCP), and maintains active corporate membership in the China Association of Petroleum Engineering Construction (CAPEC).
We hold certified Qualifications in Corrosion Protection Construction and Pipeline Detection, making us a key supplier for national energy networks.
For over two decades, we have been a qualified, stable vendor for state-owned giants such as PetroChina, Sinopec, and PipeChina.
Our international expansion includes pipeline supplies to global enterprises, including the Indian Oil Corporation and diverse operators in the Middle East, Southeast Asia, and South America.
As pipelines face higher temperature demands and eco-friendly standards, our technical roadmap focuses on three main developments:
Traditional primers with high VOCs are being replaced by eco-friendly formulations. CYCT’s solvent-free high-temperature liquid epoxy primers provide strong adhesion without emitting hazardous organic gases, conforming to strict EU environmental laws.
With shallow offshore wells and heavy oil production requiring high-temperature operations, we are developing cross-linked polypropylene (PP) sleeves that handle continuous service temperatures up to 110°C to 120°C, maintaining strong shear resistance.
Our viscoelastic solutions are designed for immediate self-repair. If minor mechanical damage occurs during pipeline handling, the cold-flowing viscoelastic compounds flow into the defect, preventing air and water from reaching the steel surface.
Complementary products to guarantee complete field-joint performance and long-term protection.
