API 7K Rotary Vibrator Hose
API 7K Rotary Drilling hoses also called oilfield drilling hoses, vibrator hoses, mud hoses, cementing hoses, kelly hoses, de-coking hoses, for the steady high pressure oilfield service. PME Grade D and Grade E rotary hose are designed and produced for mud delivery and cement service on the drilling rigs, by pumping mud at extra high pressure in oilfield drilling operation and exploration.
PME Rubber High Pressure Rotary Drilling Hoses, API 7K Certification, Grade A, Grade B, Grade C, Grade D, Grade E, Grade F. The rotary connection between mud pump and standpipe is called mud hose or kelly hose.
Drilling rotary and vibrator hoses (High Pressure Drilling Hoses) are designed as API 7K Spec as the flexible connection between the standpipe and swivel for pumping mud at a very high pressure in oil drilling and exploration. This hose features high strength spiral steel wire reinforcement which provides a very flexible connection capable of withstanding high pumping pressures at API working pressures, also called mud hose, cement hose, kelly hose or shock-resistant hose.
Rotary and vibratory hoses are made in inner rubber layer and reinforced layer.
PME Quality Rotary Drilling Hose Inner rubber layer: oil-resistant, weak acid resistant, weak base resistant and wear resistant synthetic rubber
Reinforced layer: 2-6 layer high strength coppered steel wire wound, with multiple-layer fiber wound
Our high pressure drilling hoses are often equipped with API end fittings. Connection type covers LP, NPT, TBG and BSPT thread, welding or integral forged union or flange.
