Oil Drilling Hose
API-7K Certificated Hose
The rotary drilling hose is suitable for flexible connection between the top of the drilling riser and the swivel which can move vertically. It resists corrosion of hydrogen sulfide and can deliver water, oil, mud high‐pressure media.Working pressure from 3500 PSI to 15000 PSI,dimension from 2” to 6”,for the tube type,there are three kinds available,NBR,HNBR,PTFE upon request.HNBR and PTFE tube offer excellent resistance features and suitable for almost all applications and working conditions.
