API 7K rotary drilling and shock absorption hose also called oilfield drilling hoses, vibrator hoses, mud hoses, cementing hoses, kelly hoses, de-coking hoses, for the steady high pressure oilfield service. YITAI rotary hoses 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.
