A high-pressure drilling hose is used to convey drill fluid from the drill string to the surface. This hose is commonly referred to as a Kelly hose and is used to connect the drill string and swivel together. Kelly hoses have two layers of steel cables and can withstand 5000 psi operating pressure. The inside tube is made from special NBR to improve its corrosion and abrasion resistance. Depending on the specifications, it can be equipped with multiple end fittings.
High Pressure Oil Drilling Hose
There are several important factors to consider when choosing the proper high pressure oil drilling hose. First of all, the hose must be designed for the particular type of operation that it is intended for. It cannot be used in gas drilling operations or air drilling operations. The hose must also be manufactured according to the specifications of API Spec 17B or API Spec 7K. If the hose is used in any operation that involves the exposure to pressurized gas, it will be safe.
The type of high pressure oil drilling hose that is used in the oil and gas industry is primarily determined by the use of the rig. In most cases, drilling hoses are applied in slim hole and workover rigs. A specialized drilling hose is also used in water well operations. In this case, the hoses have flexible connections in the pressure lines to convey air and mud. It is important to inspect the hose regularly and replace it if it becomes damaged.
The Kelly hose is a specialized type of oil drilling hose. It connects the standpipe to a swivel and allows drill fluid to flow through. The hose typically has two layers of plated steel cable. Its operating pressure can be as high as 5000 psi. The inside tube is made of special NBR, which provides additional strength and resistance to abrasion and corrosion. The Kelly hose is also equipped with multiple end fittings and exceeds the API 7K/ISO14693 specifications.

The working pressure of a high pressure drilling hose is around 5000 to 7500 psi. The rotary hose is often called an API 7K drilling hose. This type of hose is made from synthetic rubber with a steel wire reinforcement. This hose is ideal for oil and gas projects that require high pressure and a uniform diameter. It can be divided into five grades according to their working pressure. Here are the top features of a high-pressure drilling hose.
Operating temperature range: A rotary hose’s operating temperature range must not exceed the material’s specifications. These requirements will reduce the useful life of the Hose. Besides, users must follow the API Spec 7K specification for the operating temperature range. Moreover, they must check the temperature ranges of the hose assemblies to ensure that they meet the requirements of their applications. A high pressure drilling hose is suitable for drilling, completion, or workover operations.
The hose’s maximum length is another important aspect to look out for in a high-pressure drilling hose. While a long hose is useful in a well drilling project, it can interfere with personnel working on the drilling floor. Besides, it may also require adjustments to the height of the standpipe gooseneck and traveling equipment. That is why optimum hose lengths should be chosen carefully. But, there are many factors that can affect the length of the Hose.
High Pressure Oil Drilling Hose
If you’re in the business of high-pressure oil drilling, you’ll need a good high-pressure oil drilling hose. There are several things you should look out for when choosing the right type of hose for your job. First, check the hose’s operating pressure rating. It is likely to be too high if it exceeds 3000psi. If it falls below this level, it’s too low.
High-pressure oil drilling and hoses are also suitable for subsea applications. They can withstand high-pressure working conditions and are made from high-quality synthetic rubber. Some hoses are reinforced with spiraled steel wire to resist corrosion in high-pressure environments. A cover made of chloroprene rubber resists sun and aging. High-pressure oil drilling hoses have a high working pressure and are available in multiple grades.
The hose must meet minimum requirements if it is to be used in a rotating rig. This is a requirement for API Spec 17B. This is not possible with depressurized hoses. They prevent gas from entering the liner material at sufficient rates and can collapse. These problems can be avoided by choosing a hose that meets these minimum requirements. It will last longer and cost less in the long-term.
