Company Overview
Beijing Juneng Weiye Technology Co., Ltd. develops, produces and applies high-performance carbon-fiber and aramid composites. Our bidirectional carbon-fiber cloth, aramid cloth and S-glass cloth — the backbone of our pipe-repair offering — serve oil and gas transport, refining, chemicals, power generation, steel and other heavy industries with full-stack engineering solutions.
Service Lines
- Carbon-fiber composite reinforcement of pressure pipes
- Carbon-fiber composite reinforcement of pressure vessels
- Carbon-fiber composite reinforcement of structural steel
Typical Applications
The carbon-fiber and aramid composite repair toolkit covers:
- Refinery pipeline leaks — after a temporary seal, carbon-fiber and epoxy composite repair averts shutdown losses and keeps refining safe
- Cracks in fuel-line bends — high-strength epoxy compound plus epoxy resin and carbon-fiber cloth keep the line running and avoid losses
- Vertical risers on offshore platforms — carbon-fiber composite repair delivers excellent results
- Pressure uprating — composite reinforcement raises pipeline pressure rating
The same technology covers wall thinning, excavator damage, oil-tank leaks and more — keeping equipment in service and generating significant economic value.
Value Proposition
- Hot-work free — safe in flammable / explosive environments
- No shutdown — live-pressure repair keeps operations running
- Fast install — ambient cure; typical repair 1–2 hours
- Long life — 50-year design life, corrosion resistant
- Broad coverage — any pipe geometry, any defect type, any pressure class
