Rotary hose

High Pressure Drilling Hose Rotary and vibrator hoses 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. Structure: Rotary and vibratory hoses are made in inner rubber layer and reinforced layer. 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 Connection: 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. Features: Temperature range: -20℃～+121℃. Outer rubber layer: oil-resistant, aging-resistant and wear resistant synthetic rubber Executive standard: API Spec 7k, ISO14693, GB/T24145 Main parameters: Drilling rotary hose, shock-resistant hose, mud conveying hose (Grade A～E) / cement hose (working pressure 69.0MPa,
