What Should We Notice in Operating a Rubber Hose?

Lanphan rubber hose also called as flexible rubber hose, according to different transmission medium, select different manufacturing material. Rubber hose is a kind of flexible rubber pipe whose function is to delivery material and medium of all kinds liquid and powdery solid(under positive and negative pressure), such as alcohol, fuel oil, lubricating oil, emulsified liquid, and pumping or discharging gasoline, kerosene, diesel oil, engine oil crude oil and mineral oil under normal temperature. Flexible rubber hose is composed of inner rubber layer, one steel wire braid layer(or multilayer cloth braid or twined) and outer rubber layer. For flexible rubber hose connection type, there are flange connection and clamp connection. Comparing to rigid pipe, the biggest feature of flexible rubber hose is its flexibility.

According to different service conditions and property requirements, flexible rubber hoses are different in thousands of ways, commonly seen specification includes dimension, pressure, length, tortuosity, chemical durability and so on. Flexible rubber hose embraces advantages of long service life, wide dimension range, high loading capacity, excellent impulsion property, wide temperature range, excellent oil resistance, resistance to heat, light and durable in use. The flexible rubber hose is widely used in petroleum, chemical engineering, ships, tanker, agriculture and food industries, its application range covered every production-manufacturing.

Maters needs attention for flexible rubber hose usage:

1.Please use flexible rubber hose within suggested temperature and pressure limit.

2.The flexible rubber hose will expand and shrink with its internal pressure, so the actual length of flexible rubber hose should slightly longer than required length.

3.Please slowly open or close any valves when applying pressure, to avoid shocking pressure.

4.Please use the flexible rubber hose beyond its bending radius, otherwise, it will break off and reduce compression resistance.

5.When apply rubber hose to delivery powder and particle, it is easy to wear, please try to add the bending radius of flexible rubber hose.

6.When near by metal parts, please don’t use the rubber hose in extreme bending condition.

7.Don’t contact or near to fire.

8.Don’t trample the flexible rubber hose by car.

Matters need attention for flexible rubber hose assemble:

1.Please select suitable connector for flexible rubber hose.

2.When insert the connector to rubber hose, please smear oils on rubber hose and connector.

3.Don’t use one time push-in connector, it may cause fracture.

4.Please use professional sleeve or ribbon.

5.Don’t use connector which has scar or rust.

Matter needs attention for flexible rubber hose inspection:

1.Please inspect for the flexible rubber hose before using, make sure there has no damage, harden, soften, color changing and so on.

2.Please regular check the flexible rubber hose once a month.
