Rotary & Vibrator Hose

A rotary hose is used as a means of permitting the kelly to be either raised or lowered through the drilling process while also allowing the drill bit to be raised with the drillstring. For this reason, it is also often referred to as a “kelly hose”.

Kelly Hose API 7K

Kelly hose is a specialized type of high-pressure hose used in the oil and gas industry during drilling operations.

Pressure rating: Kelly hoses are built to withstand high-pressure drilling operations. They have pressure ratings that can range from 5,000 to 15,000 pounds per square inch (psi) or even higher, depending on the specific requirements of the drilling operation.

Rotary & Vibrator Hoses Applications

Flexible connection between standpipe and swivel (rotary drilling) or between pump and standpipe (rotary vibrator) for pumping mud at extra high pressure in oil drilling and exploration work.

Meets the severe demands of today’s drilling methods including directional drilling, pressure pulses and elevated temperatures.

The tube is designed to handle abrasive, corrosive and oil based drilling muds. The Hose cover is designed to handle external damage from abrasion, corrosion, gouges, oil and weather.
