High Pressure wire Hydraulic Rubber Hose R1/R2/1SN/2SN/4SP/4SH oil suction industrial hose

High pressure steel wire reinforced hydraulic oil pipe is mainly used for mine hydraulic support, oilfield development, suitable for engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, agricultural machinery, all kinds of machine tools and various industrial departments mechanization, automation has certain pressure in hydraulic system (high pressure) and temperature of oil (such as mineral oils, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and hydraulic transmission, the highest working pressure resistant up to 70-120 mpa.

(1) hose layout should avoid heat source as far as possible, away from the performance of engine exhaust pipe.If necessary, the casing or protective screen can be used to prevent the hose from heat deterioration.
(2) where the hose must cross or may rub against the mechanical surface during operation, the hose clamp or spring and other protective devices shall be applied to avoid damage to the outer layer of the hose.
(3) when the hose must be bent, the bending radius should not be too small, should be greater than 9 times the outside diameter.The connection between the rubber hose and the joint shall have a straight section greater than 2 times the outer diameter of the pipe.

(4) when installing the hose, avoid being in a  tensioned state. Even if there is no relative movement between the two ends of the hose, keep the hose loose. The tensioned hose will expand under pressure and reduce its strength.
(5) do not twist the hose during installation.Slight torsion of the hose may reduce its strength and loosen the joint. Tighten the joint on the hose rather than the hose on the joint during assembly.
(6) if the hose is installed on key parts, it is recommended to carry out regular inspection or replacement.

Used for mine hydraulic support, oil field development, engineering construction, lifting transportation, metallurgy forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industrial departments mechanization, automation hydraulic system
