High pressure high temperature resistant ptfe lined pipe/teflon hose pipe

DESCRIPTION:                                                                                                                

PTFE hoses are widely used throughout the Pharmaceutical, Dairy and Food Industries and can offer working conditions up to 2000 PSI and 260 degrees centigrade (although not together). Each Hose can be produced with either a smooth or convoluted inner bore.  As with stainless steel convoluted hoses, a stainless steel outer braid is standard to increase the pressure rating. Wire helix can also be incorporated into the design for use on vacuum systems. 

CONSTRUCTION:                                                                                                            

FEATURES:                                                                                                                        

1. high chemical stability.it can withstand all of the acid, including the role of aqua regia , hydrofluoric acid, concentrated hydrochloric acid , nitric acid , fuming sulfuric acid , organic acids , alkalis, strong oxidants , reducing agents and various organic solvents. Ideal for high -purity chemicals feed use .

2. low coefficient of friction. the friction coefficients is just only 0.04 and it won't change as the temperature changing.

3. great anti-adhesive, easy to adhere to the inner wall of colloid and chemicals.

4. excellent resistance to aging, long-term outdoor use.

5. excellent electrical insulation properties. ptfe is a great nonpolar materials, having good dielectric properties, and the dielectric constant is the minimun in all electrically insulating material, just only 2.0.

6. great  transparent of high quality ptfe tube can be easily observe the internal flow conditions.

APPLICATION:                                                                                                         

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.

FINISH PRODUCTS:                                                                                                

100% quality assurance.

Inner corrugated hose and out side wire braided mesh are all made of stainless steel 304.

This way can avoid media corrosion to the metal hose 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

braided mesh and inner tube.

In this way, the life-span of metal hoses are reduced largely and increase the maintenance 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.

HOW TO ORDER                                                                                                   

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

1. Temperature. You should provide us 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 improtant 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. Indenify the necessary end fittings. This is required since fittings for the assembly must be chosen to

properly fit the mating connection.
