Product Overview

Hebei Dingli Pipeline Industry Co., Ltd. produces oil drilling hoses, which are high-performance products specially designed for the oil drilling industry. The product is widely used for flexible connections between the top of the drilling riser and the swivel, as well as for adjusting installation errors between the drilling pump pipeline and the riser, thanks to its excellent pressure resistance and corrosion resistance, ensuring smooth drilling operations.

Main Product Features

• High pressure resistance: Drilling hoses are divided into two layers (2SP), four layers (4SP), and six layers (6SP) according to the reinforced layer structure, corresponding to working pressures of 15-70MPa, with higher bursting pressure.
• Corrosion resistance: Suitable for large-scale transportation of water-based or oil-based sludge under high-pressure conditions, with a minimum aniline point of 66°C, ensuring stable operation in various harsh environments.
• Flexible Connection: Facilitates the connection between the top of the drilling riser and the vertically movable hydrant, while isolating vibration to enhance operational efficiency.
• Adaptable: Wide operating temperature range from -40℃ to 120℃, catering to various environmental usage requirements.
• Complies with Standards: Adheres to API Spec 7K, ensuring product quality and performance.
