High Temperature resistant fire sleeve widely serves in petrochemical industry
Rubber industrial hoses refer to a series of flexible hoses which are mainly for industrial use. While in general, these are rubber hose including air hose, water hose, oil hose, food hose, etc. In the former piece, we learned how to choose an industrial hose pipe. Then this time, let me introduce you from another aspect. That is the type of inner tube wall.
Besides the material and property, it is better to know the structure of the inner tube wall. You will need to determine if the inner tube walls should be smooth or corrugated. So that the inner tube can bend like a flexible straw. Your special work requirement as well as pressure, flow, and discharge capacity needs can guide your decision.
Smooth inner wall of rubber industrial hoses
In a smooth bore inner tube, the inner wall of the tube is smooth and has no wrinkles. Thus the medium will flow smoothly without any barrier. Then the fluid transfer capacity will be very high. When you require precise flow control, a smooth bore rubber hose will be better. Because there will be no interference with flow due to wall irregularity. Smooth bore inner tube also aids drainage. All the industrial hoses except metal hose can be with corrugated inner wall.
Ripple wall
The pipe wall is folded based on a certain pattern to improve the bending ability. Such kind of flexible rubber hose has excellent bending property.
There are two types of corrugated inner tubes, spiral and ring. The spiral design is a single corrugation that spirals around the length of the hose. This design helps increase flow. Besides, it is suitable for the apps that ask for good flexibility. While ring design is common in metal pipe and feature a series of interconnected rings. The ring-shaped inner metal tube has deeper corrugations. Because this can be more flexible.
