Stainless steel corrugated hose is a general purpose industrial hose and is available in different grades of stainless steel including 304, 316L, 321,etc.There are many different kinds of metal hose fittings,such as gas hose fitting,quick camlock,flange,NPT fittings,BSP fittings,etc.The flexible metal hose with fittings is more conducive to function in the piping system.
Flexible metal braided hose eliminate the problems of rigid connection and can be used in all kinds of steam, water, oil and gas systems with its pressure resistance and elastic structure.In complex piping systems, there are often difficulties due to space position conditions, resulting in installation difficulties.The flexible metalic hose is extremely flexible due to its ability to bend at will and bend under the rated bending radius. Therefore, it can removal of problems caused by assembly.
The corrugated hose is manufactured from a cylindrical, thin walled tube formed from rolled strip and welded at the seam. Impressed into this tube is a corrugated annular profile. Annular corrugation means each convolution is perpendicular to the centre line of the hose giving a distinct advantage of movement with each corrugation being relatively independent of movement from each other.
When the corrugations are closely spaced, the hose is referred to as ‘closed pitch’ hose. Conversely, when the corrugations are more widely spaced, the hose is referred to as ‘open pitch’.
Comflex corrugated metal hoses are manufactured from quality proven components and cutting-edge technology.The bellow is the body of the metal hose, which plays the role of flexibility; the wire braids play the role of strengthening and shielding; the fitting acts as a connection. For different use requirements, the ways of connecting them are different: the bellows,wire braid and fittings are connected by welding, called welding type; they are connected by mechanical clamping, called mechanical clamping type; In addition,there is a combination of the above two methods, called hybrid.

There are many different types of flexible metal hoses. Are you still worried about how to accurately choose the products you want? To accurately select the metal hose you want, we can follow these steps. Tell us the following information and you can get a precise quote.
SUS 304 Austenite stainless steel is usually referred to as the Japanese name for SS304 or AISI 304 stainless steel.304 stainless steel is a common material of stainless steel, the density of 7.93 g/cm3 and resistance to high temperature 800 ° C.It has good processing performance and high toughness.They are widely used in medical industry and furniture decoration industry and food industry.
Flexible metal hose made with ss304 has good comprehensive performance of corrosion resistance and formability.Stainless steel 304 flexible metal hose is durable in use , good and inexpensive, will bring the best result of use and good economic benefits to you.
ss321 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to ° F (427 to 816° C).
ss321 also advantageous for high temperature service because of its good mechanical properties. sss321 offers higher creep and stress rupture properties than ss304.Therefore,if your tube needs to work under high temperature conditions, please select the flexible metal hose made by ss321.
Wire braids are made by the a few metal wires that cross each other or a few metal strip that split to be braided by certain order, with specified angle setting in the outer surface of metallic hose, having the effect that strengthens and shielding.Wire braids not only shares the static load of the metallic hose in axial and radial direction, but also ensures the safe and reliable operation of the metallic hose under the condition that the fluid flows along the pipe and produces pulsation effect. At the same time, it also ensures that the corrugated part of the metallic hose is not directly affected by relative friction, impact and other mechanical damages.The strength of the flexible metal braided hose can be increased by ten to dozens of times.The highest shielding capacity can reach 99.95%.
Firstly,the function of the metal hose fittings is to connect the wire braid with the flexible metal hose as a whole.At the same time, the metal hose fittings are the part of the connection between the metal hose and the metal hose or other pipe fittings and equipment.It ensures that the medium works properly in the piping system.The material of the joint are usually the same as the material of the bellows and mesh sleeve, mostly stainless steel.In order to reduce production costs, some of the larger size of the metal hose in the transmission of corrosive medium is not strong or not corrosive, the metal hose fittings can be made of carbon steel;For the connection of metal hose under corrosive medium working condition, if appropriate measures are taken in the design to avoid contact with the medium, carbon steel can also be used.

NPT stands for National Pipe Tapered threads, also known as ANSI/ASME B1.20.1 pipe threads. It is a U.S. standard for measuring tapered threads on threaded pipes and fittings. Sometimes referred to as MPT (male pipe threads), NPT threads are not interchangeable with NPS (National Pipe Straight) threads. Unlike straight threads found on a bolt, a taper thread will pull tight, making a closer seal.

A pipe end is the description of how the section of pipe ends. There are three main types of pipe ends: beveled, threaded or plain. Understanding pipe ends is important when designing a piping system since it would be inappropriate for the designer to specify a threaded connection for a large diameter pipe or to specify a welded end when connecting to a threaded component.
A bevel is a surface that is not at a right angle (perpendicular) to another surface. The standard angle on a pipe bevel is 37.5° but other non standard angles can be produced. Beveling of pipe or tubing is to prepare the ends for welding. However, it can also be used for deburring the cut ends for safety or aesthetic reasons. Bevel end is abbreviated on drawings as BE.
The beveling process is generally automated. This is because a pipe beveling machine can cut the bevel much faster than hand grinding, flame cutting or turning the pipe on a lathe. Further, the automated process ensures that there is an accurate and consistant pipe bevel each time. The automated process is much safer as operating personnel are not exposed to the same hazards as a person beveling the pipe.
This is the most commonly used end and is used on pipe, pipe nipples, and swage nipples.
Typically used on pipe 3" and smaller, threaded connections are referred to as screwed pipe. With tapered grooves cut into the ends of a run of pipe, screwed pipe and screwed fittings can easily be assembled without welding or other permanent means of attachment. In the United States, the standard pipe thread is National Pipe Thread (NPT). The reason for this is that as NPT connections are assembled, they become increasingly more difficult for the process to leak. The standard taper for NPT pipe is 3/4" for every foot. Threaded End is abbreviated on drawings as TE.
Threaded fittings have threads that are either male or female. Male threads are cut into the outside of a pipe or fitting, while female threads are cut into the inside of the fitting. As screwed pipe and fittings are assembled, two pieces are pulled together. The distance that is pulled together is called the thread engagement.
A pain end pipe is a pipe that has been cut at 90° perpendicular to the pipe run. The reason pipe would be specified as plain end rather than beveled end is when the pipe will be used in a socket weld connection or for use with a slip-on flange.

Corrugated metal hoses come in many configurations. These tools can help ensure you select the right corrugated metal hose for your application.
There are many components in a metal hose assembly and care should be taken when selecting each of them. Moreover, the components have their own unique technical limitations so it is important to make sure each of the components is compatible with your application. In much the same way as a “chain is as strong as its weakest link”, a metal hose assembly will only perform to the limits of its weakest component.
Once the components have been selected, the quality and skill of the fabricator assembling the components becomes important. The procedures and care used when fabricating assemblies also has a dramatic effect on the assembly’s overall performance.
Hose Master has invested a considerable amount of resources to researching metal hose fabrication and developing a state-of-the-art fabricating center. In addition, we share the welding technology we have developed with our fabricating distributors. All of this is done to promote quality and consistency in fabricating metal hose assemblies.
In this section, we will discuss the various components that make up a corrugated metal hose assembly, and what information a metal hose fabricator will need in order to make an assembly for your application. If you need assistance determining the information, we have also included an explanation of how to analyze the application and make the appropriate selections.
In order to make an assembly, the fabricator will need answers to the following five questions. For more information about any of these questions, or for a list of available options, click the topic heading for a more detailed explanation.
If you have the answers to these questions, a metal hose fabricator will be able to make the assembly. If you do not know the answers to all five questions, you will need to obtain them. The next section is designed to help you determine the answers.
To properly design a metal hose assembly for a particular application, the following design parameters must be determined. To help remember them, they have been arranged to form the acronym “S.T.A.M.P.E.D.”
Corrugated metal hose is used in a very broad spectrum of applications. Just as the hose, fittings, and other assembly parts must be tailored to suit the demands of the service, so must the methods of joining these components. While standard production joining methods work very well for the majority of service demands, the following extremes may dictate special joining or fabrication techniques:
Hose Master has developed specialized welding, brazing, joining, and fabrication procedures to assure the integrity and serviceability of metal hose assemblies in even the most extreme applications.
The fabrication options to be considered are:
In each of the following sections, the standard method and available options are explained. Select the options best suited for your application.
This method will be used unless another method is specified
Standard fabrication of an assembly generally consists of:
Standard fabrication sometimes leaves a portion of the cut corrugation, or corrugation “lip”, just under the base of the fitting. In specialized applications this residual lip may not be desirable. To prevent any exposed corrugation edges from causing damage, the hose can be specially prepared for welding by cutting the corrugation on the crest, rather than in the valley, thereby removing the lip.
For applications in which corrosion is a concern, all crevices and fissures must be minimized. Specialized hose and fitting preparation, in conjunction with proprietary welding techniques, is available to provide a full penetration hose-to-fitting weld that is smooth and crevice free.
Assemblies operating at the upper limits of their rated working pressure or in severe service may benefit from a braid-over construction. The fitting is first welded to the unbraided hose. Then a special metal reinforcing ring is installed over the fitting and next to the weld. Finally the braid is drawn over the end of the hose and the ring, and welded to the side of the fitting. This technique reduces the amount of heat introduced into the braid wires, nearly eliminates the heat effected zones of the cap and attachment welds, and maximizes the wire strength. Braid-over construction may also be used for specific high cycle applications.
Note: Always test an assembly with a medium that has a smaller molecular or atomic size than the service required.
Every corrugated hose assembly is leak tested prior to shipment. Standard testing consists of pressurizing the assembly with air and then submerging the entire assembly under water. This method is reliable and sufficient for the majority of applications.
While the standard test is designed to detect leaks, hydrostatic testing is designed to test the assembly’s strength. Testing of an assembly to its full permissible test pressure can be economically and accurately accomplished by filling the assembly with liquid while concurrently evacuating all air. The assembly is then hydrostatically pressurized using high pressure pumps. The test pressure is maintained for a predetermined period of time.
Testing with air under water, at pressures of up to psi, is available for specialized applications. For a more sensitive test, the use of gases such as nitrogen or helium can be requested.
Dye penetrant testing is available for both leak and for weld bead inspection, in accordance with Hose Master procedures or to customer specified standards.
This is the most sensitive leak detection method generally available. The standard test method is to attach the assembly to a mass spectrometer and generate a very high vacuum in the assembly. The exterior of the assembly is then flooded with helium. The relatively tiny helium atoms penetrate even very small openings and are drawn into the mass spectrometer where they are detected and the leak size quantified. Helium Mass Spectrometer testing can be modified to satisfy customer or regulatory agency requirements.
The hydroforming method of corrugated hose manufacturing inherently yields a very clean product. However, specialized cleaning for specific applications is available upon request. Contact Hose Master’s Customer Service Department for details.
All assemblies are shipped with protectors over sealing surfaces such as threads and flange faces. Spacer bars are installed on all shorter double-flanged assemblies to prevent compression of the assembly during shipping and handling. Special packaging is available to suit customer requirements, including crating, plastic bagging, labeling, and custom fitting protectors.
