Frequently Asked Questions
What Is a Kelly Hose?
Kelly Hose is a type of high-pressure hose that is used to connect the top of the drilling rig to the drill string.
Kelly Hose (also known as a mud hose or rotary hose) is a flexible, steel reinforced, high pressure hose that connects the standpipe to the kelly (or more specifically to the goose-neck on the swivel above the kelly) and allows free vertical movement of the kelly while facilitating the flow of drilling fluid through the system and down the drill string. The Kelly hose has a diameter of 3-5 inches (inside diameter).
What Are Kelly Hoses Made Of?
Kelly hoses are typically made of rubber or steel-reinforced rubber. They are designed to withstand high pressure and abrasion, and are available in a range of sizes to accommodate different drilling depths and rig configurations.
How Long Are Kelly Hoses?
The length of a Kelly hose can vary depending on the drilling depth and the distance between the mud pump and the swivel. Kelly hoses are typically available in lengths of 40 to 90 feet.
How Are Kelly Hoses Connected to the Drill String?
Kelly hoses are typically connected to the drill string using a threaded connection. The hose is attached to the top of the kelly, which is then screwed into the drill string.
How Are Kelly Hoses Maintained?
Kelly hoses should be inspected regularly for signs of wear or damage, and replaced if necessary. They should also be stored and handled properly to prevent kinks, twists, or other damage that could affect their performance. Regular cleaning and maintenance can help extend the life of a Kelly hose.
Are Kelly Hoses Regulated by Any Industry Standards?
Yes, Kelly hoses are regulated by industry standards such as API 7K. This specification outlines the requirements for drilling and well-servicing equipment, including Kelly hoses, to ensure they meet high standards of quality and safety.
