Why choose our metal flexible hose ?


1.100% quality assurance. Inner corrugated hose and outside wire braid are all made of stainless steel 304. 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 life-span of metal hose are reduced largely and increase the maintenance and time cost to the customers. Whats worse, the poor quality metal hoses are easy to cause the leakage of media, and then cause the security incidents.

2. We manufactured all the metal hoses according to the request of pressure grade strictly. Never have the phenomenon of thin wall and poor waves. This way guarantee the hoses compressive strength and fatigue lifetime very well and prolong the life-span of metal hose.

3. We promise all the metal hose will be examined strictly before deliver even large quantity order. To the metal hose used in the high pressure environment, we even will arrange 3 to 4 times pressure test before deliver. 




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

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

2.Size-- The diameter of the connections in which the assembly will be installed is needed to provide

3. 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

4.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

5. Identify the necessary end fittings. This is required since fittings for the assembly must be chosen to properly fit the mating connections.
