High pressure anti-vibration stainless steel flexible corrugated steam metal braided hose

 

 

 

Product Description

 

 

What's the flexible metal braided hose?

 

Flexible metal braided hoses and fittings can be used widely in systems like water, steam, hot oil and gas with their resistance to pressure and flexibel structure.

 

They are utilized for conducting liquids, compensating the problems originated from installation, absorbing vibrations and expansions.

 

Flexible metal hoses may be strengtened by double braiding in order to increase their resistance to pressure and environmental conditions. It is also possible to reinforce them by springs with different wire thicknesses or by stripwounds to lengthen their service life for more sever environmental condition.

What's the Advantages of flexible metal braided hose?

 

1. With good characteristic of light weight, large diameter, good flexibility, resistant to high temperature, high pressure and corrosion.

 

2. With available double SS304 wire braid for high working pressure.

 

3. The inner tube is made of stainless steel corrugated tube which equips with good performance of high temperature and hig-pressure resistance.

 

4. Applied to repeated motion in high temperature areas, good anti-fatigue performance.

 

 

 

What's the Application of flexible metal braided hose?

 

Flexible metal braided hoses are widely used in the areas of heating, ventilation, conditioning systems, iron and steel industry, chemical and petrochemical facilities, oil and gas refineries, chemistry and food industries, aircraft and ship construction facilities.

 

 

 

 

 

Installation Guide

 

1. Avoid torque.

Do not twist the hose assembly during installation when aligning the bolt holes in a flange or in mating up pipe threads. The utilization of lap joint flanges or pipe unions will minimize this condition. It is recommended that two wrenches be used in making the union connection: one to prevent the hose from twisting and the other to tighten the coupling.

 

2. Prevent out-of-plane flexing in an installation.

Always install the hose so that the flexing takes place in only one plane--this being the plane in which the bending occurs.

 

3. Avoid over bending.

The repetitive bending of a hose to a radius smaller than the radius listed in the specification tables for corrugated hose will result in early hose will result in early hose failure. Always provide sufficient length to prevent overbending and to eliminate strain on the hose.

 

4. Avoid careless handling of the hose assembly.

Always lift or carry metal hose to prevent abrasion damage particularly to braided corrugated hose. Store metal hose assemblies away from areas where it can be subjected to spillage, corrosive fumes or sprays, weld splatter, etc.

 

5. Always support the piping.

A piping system which utilizes metal hose to absorb movement must be properly anchored and / or guided.

Always support the piping to prevent excessive weight from compressing the hose and relaxing the braid tension.

100% quality assurance. Inner corrugated hose and outside wire braid are all made of stainless steel304/316. For this way can avoid media corrosion to the metal hose and largely prolong the life-span of the metal hose.

 

Poor quality metal hoses are usually made of SS202, even some suppliers use the material of SS201 to make the wire braid and inner tube. In this way, the lifespan of metal hose are reduced largely and incerease the maintence and time cost to the customers.

 

What's worse, the poor quality metal hoses are easy to cause the leakage of media, and then cause the security incidents.

 

 

Purchase Guide:

 

To properly design a metal hose assembly for a particular application, the following design parameters must be determined

 

Temperature.

You should provide us this information as the temperature to which the assembly is exposed a proper fit   

Size.

The diameter of the connections in which the assembly will be installed is needed to provide

Media.

This is important since you must be sure that the assembly's components are chemically compatible with the media going through the hose as well as the environment in which the hose is installed

Pressure. 

Identify the internal pressure to which the assembly will be exposed. This information is important to determine if the assembly is strong enough for the application

Identify the necessary end fittings

This is required since fittings for the assembly must be chosen to properly fit the mating connections
