Description
Drilling hoses, also known as rotary hoses, are essential components in the oil and gas industry. These hoses are manufactured in compliance with API 7K specifications and are used in a wide range of drilling operations, including well drilling, well cementing, work-over, and down-hole servicing. They provide a flexible hose connection between the top of the oil drilling standpipe and the vertically moved swivel joint. These hoses are designed to withstand high pressure, extreme temperatures, and harsh environments, making them ideal for transferring high-pressure oil and water-based mud.
Description
Drilling hoses (rotary hoses) are crucial for maintaining the efficiency and safety of drilling operations. These hoses help in adjusting installation discrepancies between drilling pipelines and standpipes, reducing vibrations and shocks. In high-pressure conditions, they efficiently transfer drilling fluids such as oil, water, and mud with an aniline point as low as 60°C. Their reinforced structure ensures durability, and they play a vital role in preventing failures during drilling operations.
The hoses are constructed with high-strength steel wire reinforcement to withstand extreme conditions. The inner tube is made from oil-resistant synthetic rubber, while the outer cover is designed to resist abrasion, corrosion, and environmental impacts. Their flexibility allows them to adapt to various operational needs, ensuring optimal performance.
