PEEK Flood Plug Seals
JUNDE has cooperated with Saudi Arabia, PetroChina, Sinopec, University of Petroleum, Xi’an and other customers to produce PEEK support sealing ring, PEEK front and rear plugs, PEEK insulating ring, PEEK polar plate, PEEK insulating wire, PEEK spacer ring, PEEK retaining ring, PEEK Wear-resistant shaft sleeves and other products.
High-performance plastic parts such as high-temperature wear-resistant bushings, insulating rings, and front and rear plugs made of PEEK and its modified composite materials can replace traditional materials such as copper alloys, stainless steel, PTFE, ordinary engineering plastics, and graphite. Oil logging and production equipment have strict technical requirements for parts such as wear resistance, high temperature resistance, high strength, oil-free lubrication, acid-base corrosion, and high reliability, which can reduce operating costs and help equipment to continuously operate at the highest production capacity. stable production.
We will be in very short time to give you a satisfactory answer.
Continuous Carbon Fiber CF/PEEK Composite Pipe
- 67% longer service life than steel pipe
- 65% lighter than metal pipes
- More resistant to corrosion by hydrogen sulfide and carbon dioxide than steel pipes
- Long-term use in methanol and 160℃ environment
- Smooth corrosion resistance ensures excellent fluidity
- Replaces corrosion-resistant alloys used in oil and gas industry piping systems
PEEK for sealing: a reliable sealing solution
- In seawater, hydrocarbons, and 100% hydrogen sulfide gas environment, 100% strength retention after 1000 hours at 175°C
- Double the pressure resistance of PTFE
