PEEK Flood Plug Seals

Jiangsu Junhua Special Plastics 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.

PEEK Gear Application

The PEEK polymer and composite high-performance plastic parts produced by the company have been widely used in various links such as downhole measurement, oil exploration, petrochemical plant production and transportation.

Continuous Carbon Fiber CF/PEEK Composite Pipe

◆67% longer service life than steel pipe

◆65% lighter than metal pipes

◆It is 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 that are often used in the oil and gas industry to replace those used in piping systems.

PEEK for sealing: a reliable sealing solution

◆In the environment of seawater, hydrocarbons, and 100% hydrogen sulfide gas, the strength retention rate reaches 100% after a high temperature of 175 ° C for 1000 hours

◆Double the pressure resistance of PTFE

◆300 times higher creep resistance than PTFE

◆It is 18 times more resistant to compression and creep than PTFE

◆Replace the metal spring to reduce the risk caused by the wear of the seal and the contact with the well wall (energy absorbing spring)

In some industries, including the oil and gas industry, the primary use of PEEK is to provide mechanical support for softer sealing materials such as elastomers and fluoropolymers, while in others the properties of this material make it Ideal for use as a primary seal.

Application of PEEK in ESP electric submersible pump (submersible electric pump)

◆Excellent high temperature resistance, excellent insulation even at 250℃

◆Maintains high mechanical strength even at 250℃

◆It still maintains high reliability under high temperature of 200℃ and high pressure of 140MPa for a long time.

◆Excellent high temperature resistance and excellent insulation, even at 250℃, it still maintains high mechanical strength.

Application of PEEK logging instrument: excellent abrasion resistance and insulation

◆It still maintains high reliability under high temperature of 200℃ and high pressure of 140MPa for a long time.

◆Insulators can be used for a long time without being corroded in underground high temperature and strong acid medium (H2S, SO2).

◆Has a unique combination of performance, wear resistance, chemical resistance, mechanical strength, and stable electrical properties over its entire operating temperature range, which helps maintain the integrity of collected data, while bringing electrical Less distraction.

PEEK wire and cable application: excellent high insulation performance

◆Lower water absorption and better toughness than polyimide (PI)

◆Excellent cutting resistance and corrosion resistance to ensure zero electric short circuit

◆Stable chemical corrosion resistance under 200℃ and 100MHz environment

◆Permeability

◆No need to dip insulating varnish like PI wrapping wire, reducing cost

PEEK connector application: improve the overall performance of downhole connectors

◆Two times longer life than glass-ceramic connectors

◆Twice the power transmission capacity of glass-ceramic connectors

◆Excellent insulation performance ensures no leakage

◆Excellent resistance to corrosive liquids and gases

◆PEEK polymer has high purity and strength, which can allow the design of thinner thin-walled sections in more compact connectors, and can have excellent performance even in small spaces.

◆Withstands typical oil and gas industry fluids, including seawater, mineral and silicone oils, and hydraulic fluids, and is also suitable for hydrogen sulfide (H2S) sour gas wells. PEEK performs well above the NORSOK M-710 standard, an important specification for the oil and gas industry.
