•Certification: API 7K ISO 14693-ABS APPROVAL

Indroduce: 

In oil drilling and exploration, the Rotary drilling hose delivery the ultra-high pressure mud from the pump to the standpipe, it is a flexible connection between the rotary (rotary drilling) pump and the riser (rotary vibrator). It meets the strict requirements of directional drilling, negative pressure pulse and high temperature downward connection. The hose can also be used as a motion compensation hose to stabilize rotary drilling and pumping equipment on offshore drilling platforms under the action of vertical waves.
