Mechanical Seal Washpipe

The JJC Tec high-performance mechanical seal washpipe adopts a unique patented design and applies new composite ceramic materials, with longer service life, simpler installation / maintenance and higher reliability. Especially under the working conditions of high temperature, high pressure and high speed, the service life is much longer than that of the traditional packing washpipe. It is suitable for all kinds of top drives and appraised by all customers.

Highlights

Durability

Seal ring working life up to 2000 hours operating time with pressure. Completely solving the problem of short sealing life of traditional washpipe under high temperature, high pressure and high speed drilling conditions.

Easy Maintenance

It takes only 10 minutes or less to replace the seal rings with a ratchet wrench, which can significantly improve efficiency, reduce labor intensity and enhance operational safety.

Flexibility

The excellent tracebility of the stationary seal ring to the rotational seal ring makes the installation interface tolerance requirements much lower. Suitable for all kinds of operating environment and different models of top drives, install-and-play.

High performance

The main structure is made of high strength stainless steel, corrosion resistant. The seal ring friction pair is made of wear-resistant, corrosion-resistant, and high-temperature resistant high performance composite ceramic materials, withstands a high working temperature up to 120 ℃ and a high work

Technology Innovation

The washpipe adopts patented mechanical seal floating structure design. Chinese and American invention patents and many international scientific and technological achievements have been awarded.

Remarkable Benefits

Completely solving customers' problem in drilling operations under high temperature, high pressure and high speed conditions, greatly improves operation safety, greatly reduces labor intensity, and greatly reduces customers' comprehensive operating costs and risks.
