high pressure well drilling Top drive Washpipe

Long working life

Up to 2000 hours under pressure. It completely solves the problem of short life of traditional flushing pipe seal under high temperature, high pressure, high speed and other drilling conditions.

Maintenance is easy and fast

The seal ring can be replaced in just 10 minutes with a ratchet wrench. Significantly improve work efficiency, reduce labor intensity, and enhance work safety.

Wide range of application

The following performance of the static ring to the moving ring is excellent, and the tolerance requirements of the installation interface are greatly reduced. Suitable for a variety of operating environments and different types of top drive, ready to use.

High performance

The main structure is made of high-strength stainless steel material, which is resistant to corrosion. The sealing ring friction pair is made of wear-resistant, corrosion-resistant and high-temperature high-performance composite ceramic material, which can withstand the high temperature of 120 ℃ and the high pressure of 52.5MPa.

Technological innovation

Flushing pipe adopts patented technology (invention patent No. : 201510346602.7; Us Invention Patent No. : 9,976,359) mechanical seal floating structure design, won a number of Chinese and American related invention patents, and won a number of domestic and foreign scientific and technological achievements awards.

Remarkable benefit

It completely solves the pain points of customers' drilling operations under high temperature, high pressure and high speed conditions, greatly improves operation safety, greatly reduces personnel labor intensity, and greatly reduces customers' comprehensive operating costs and operating risks.
