What are the classifications of flexible conduit hoses?

As the name suggests, hoses are some relatively flexible pipes. These pipes can be bent and folded at will without cracking. The more common hoses in our daily life are plastic hoses and PVC hoses. These two hoses have a longer service life and are more resistant to high temperatures. In addition to these two types of hoses, there are many classifications of hoses. Here is a detailed introduction to the classifications of hoses.


1. Hose

According to the purpose, it is mainly divided into: threading hose, drainage hose, ventilation hose, shower hose, wiring harness tube.

According to the material, it is mainly divided into: stainless steel hose, metal hose, corrugated hose, rubber hose, and plastic hose.


2. Threading

The threading hose is mainly made of galvanized steel belt, stainless steel belt, PA, PE, PP and other plastic materials. Uses: Machinery manufacturing.


3. Electrical.

Insulation protection, lighting equipment, automobile manufacturing, aviation equipment, subway, train, automation control and other industries of wire and cable protection. Features: Good flexibility, distortion resistance, good bending performance, can withstand heavier loads; acid, lubricating oil, coolant, etc., shiny surface, friction resistance. It can withstand the heavy pressure of footsteps, does not break, does not change shape, can quickly recover, and there is no damage to itself.


3. Stainless steel

Stainless steel hose mainly refers to the hose made of 304 stainless steel or 301 stainless steel. Uses: Used as a wire protection hose for automatic instrument signals. The stainless steel hose used to protect the precision optical ruler and the sensing circuit. It has good flexibility, corrosion resistance, high temperature resistance, abrasion resistance, tensile resistance and water resistance. And provide a certain shielding effect.


4. Metal

Metal hose mainly refers to a spiral corrugated pipe; the other is an annular corrugated pipe.

The spiral corrugated pipe is a tubular shell with corrugations arranged in a spiral shape. There is a spiral angle between two adjacent corrugations, and all the corrugations can be connected by a spiral line.

The ring-shaped corrugated pipe is a tube-shaped shell with the corrugations in a closed circular ring shape, and the waves are formed by connecting the circular corrugations in series. Annular corrugated pipe is formed by seamless pipe or welded pipe. Restricted by the processing method, the length of a single tube is usually shorter than that of a spiral corrugated tube. The advantages of annular bellows are good elasticity and low rigidity.


The above is the introduction to the classification of hoses. There are many classifications of hoses, but in general they are inseparable from these.
