High Pressure

In oil drilling and exploration work, it is often necessary to bear a lot of pressure. The oil drilling and production hoses produced by us can be used normally in the environment of high pressure of 200Mpa, and can transport water-based mud and oil-based mud under high pressure. The higher the pressure, the more steel wire layers are added, and the more stringent the production process requirements are. Our designers use 2-6 layers of high-strength and super-flexible steel wire or steel wire rope, which can withstand high pressure.

Equal Diameter

After the ordinary rubber hose is installed with the joint, the inner diameter of the joint part of the hose will be compressed a lot. The oil drilling and production hose we produce has the characteristics of equal diameter. When the medium flows through the joint, the generation of eddy current is reduced, the resistance is reduced, and the protection Rubber hose, avoid friction of inner layer, longer service life.

Lightweight

API 7K Series - Rotary Drilling and Shock Absorbing Hose, with the characteristics of light weight, API series products are 25% lighter than other ordinary coiled pipes. Lighter hoses help improve fuel economy, reduce shipping costs, and are easier to handle and install.

Provide oilfield rubber hose and end fittings
Flexible drilling rubber hose plays an important role in oil extraction. They should withstand high operating pressures, extreme operating temperatures, wear and other inferior componentswhite. The maximum working pressure for steel cable strength members is up to 15,000 psi. The steel wire is usually galvanized or copper plated to improve the resistance of the steel wire to rust and corrosion. Since the rebar is thick, the hose should be handled or stored in the correct way to avoid kicking or pinching. They will greatly reduce their rated working pressure.
