Rotary drilling is used to cut deep holes into rock formations. It is useful for many applications such as environmental monitoring, oil drilling, and coal mining. Rotary drill hoses connect the standpipe to the swivel, which is a moving part within a derrick. They must be flexible and strong enough to withstand high amounts of pressure.

Flexibility

Rotary hoses are used to connect the standpipe to the rotary swivel, which is a moving part within the derrick. Therefore, they must be strong enough to withstand high amounts of fluid pressure without creating instability within the system. Most rotary hoses are constructed with black synthetic rubber that is resistant to oil and abrasion. They also feature multiple wire plies and a steel crimp coupling that is capable of withstanding extreme pressures. The hoses are also equipped with low-temperature and weather proof properties, making them suitable for use in various environments. This flexibility helps keep operations on schedule, which can help reduce overall cost and project timelines.

Durability

Rotary drilling is used for a variety of projects, including water well drilling and coal mining. It can also be used by the environmental industry to install groundwater monitoring wells, or by contractors to drill holes for new homes. In addition to its versatility, rotary drilling is easy to use and maintain. Drilling hoses are a vital part of the derrick system, and are usually fabricated from a rubberized polymer strong enough to contain high amounts of pressurized fluids. The hose connects the standpipe to the swivel, and helps to move the kelly. Slim hole rotary drilling hoses are designed according to API 7K spec as the flexible connection between the top of oil drilling stand pipe and vertically moved swivel joint for pumping mud at very high pressure in oilfield drilling operation and exploration. The hose features a steel wire braid reinforcement and an oil, ozone, hydrocarbon and acid resistant synthetic rubber cover. It can be used for a wide range of temperatures.

Corrosion Resistance

Rotary drilling hose is used to transfer water, oil and high-pressure drilling liquids to and from the drill pipe and the mud pump. This hose is usually made from a durable, weather-resistant rubber and can handle high pumping pressures without leaking or bursting. It can also withstand exposure to corrosive chemicals such as hydrogen sulfide. Drilling rotary hose (also known as kelly hose or mud hose) is designed according to API 7K spec and used as flexible hose connection between the top of the standpipe and swivel that can move vertically for pumping mud at very high pressure in oilfield drilling operation and exploration. It has high strength spiral steel wire reinforcement and an abrasion, acid, alkali, ozone and flame resistant synthetic rubber cover. It is available in a wide range of ID sizes and lengths from 2 to 5 inches and can be used on various types of rigs including portable, work over and seismograph drilling rigs. It has built-in API end fittings and can be connected using a threaded hammer union, coupling or integral flange.

Pressure Resistance

Rotary drilling hoses must be flexible enough to move with the derrick, yet strong enough to hold large amounts of fluid pressure. This means they must be made from a material that is both strong and soft. The rotary drilling hose on a rig is a flexible line that conducts high-pressure mud to the swivel, which in turn transmits the fluid to the drill bit. It's a critical component for drilling a hole in the ground. This type of rotary hose is commonly used in work over, slim hole and seismograph drilling applications with up to 5,000-psi rated working pressure depending on the size. This rotary hose is made from a rubberized polymer that can resist impact and vibration, as well as stand up to the high amount of pressure it must endure. It is also resistant to abrasion, ozone, oil, cuts and weather. It's often used in mud hoses, cementing hoses and kelly hoses for the transportation of water, drilling fluid and oil.
