Rotary drilling hoses are a critical component of drilling equipment. They transport drilling fluid from a standpipe to a rotary swivel. Depending on the application, rotary drilling hoses can operate at pressures from 1,500 to 5,000 PSI. These hoses can be used in oil and water wells.
Rotary drilling hoses are made from three main components: a tube, a reinforcement, and a cover. The tube is made from synthetic rubber and reinforced by spiraled steel wire for strength. The cover is made of chloroprene rubber, which is extremely resistant to abrasion. These three components combine to form a flexible and durable hose.
The manufacturer must consider the pressure and the medium to be conveyed when determining the size of the hose. The hose should be thick enough to withstand the medium, and the lining material should be strong enough to withstand the heat and chemical effects of the medium. The lining material must also be able to resist external pressure and avoid kinking in sharp bends.
Small and medium-sized drilling rigs use rotary drilling hoses. They carry high-pressure drilling liquids such as mud and air and are commonly fitted with API end fittings. They can be used to pump mud up to four thousand PSI, depending on the application. They can also be used to cement and fracturing.
A kelly line is another important component for drilling operations. This large diameter (3 to 5 inches inside diameter) high-pressure flexible line is used to raise and lower the drill string. Drilling is made easier by the ability to simultaneously raise or lower the drillstring and pump drilling fluid. The use of a kelly line will minimize downtime and increase safety.
