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%.
We make stainless steel tubular shielded braid manufactured with type 304 soft drawn Stainless Steel. They are widely used on flexible metal hoses,both for corrugated and interlock hoses.We supply double layer or single layer braids. The braids are used where highter temperature or greater mechanical strength is needed.
The size range of the hose that we can braid is DN6-600mm.Normal metal hoses use only one layer of mesh sleeves; for special applications, they are also woven in two or three layers, depending on the specific working pressure. Depending on the size of the bellows and the requirements for its use, it is usually made of wire with a diameter of 0.3 to 0.5 mm. The wire is 5~18 per strand, one strip per ingot. The steel wire mesh sleeves produced are mostly 24, 36, 48, and 64 strands, and the bellows with extra large diameters, as well as 96, 120, and 144 strands. The main weaving parameters of the net sleeve are in addition to the number of strands (wire), the diameter of the wire, the number of ingots and the thickness of the strip, as well as the coverage area, the weaving distance, the weaving angle, and the like. They are all important basis for determining the performance of metal hoses.
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.

BSP Fitting
BSP（British Standard Pipe) according to the shape can be devided into:BSPP（British Standard Pipe Parallel）and BSPT（British Standard Pipe Taper）。
BSPT (British Standard Pipe Thread) is similar to NPT except for one important difference. The angle across the flanks of threads (if you sliced the fitting in half long-ways and measured the angle from root to crest to root) is 55 degrees instead of 60 degrees as it is for NPT. This is a popular fitting in China and Japan but is very rarely used in North America unless the equipment to which it is attached was imported.
BSPP (British Standard Parallel Pipe) is most popular in the UK, Europe, Asia, Australia, New Zealand and South Africa. It is a parallel thread fitting that uses a bonded seal ring to do the sealing. This bonded ring seal is sandwiched in-between a shoulder on the male fitting and the face of the female fitting and is squeezed in place.
gas hoseRussain type camlockcamlock600flangehose with fittingsBSPA 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.

While corrugated metal hoses and expansion joints can accommodate many different end fitting types, pipe flanges are one of the most common connections specified by customers. However, we find there is a good deal of confusion in our industry as to the proper use of pipe flanges on metal hoses and expansion joints. Here are a few things to keep in mind when helping customers with flanged assemblies.
Pipe flanges allow for easy installation of the component into a piping system. Proper flange usage avoids many potential problems associated with threaded connections (space limitations, thread allowances, numerous thread standards, thread sealing challenges, etc.). Flanges must be manufactured in accordance with well-defined specifications, which are then referenced in piping codes that are used in various industries. Industry relies on these codes and standards to ensure the safety and consistency of a properly designed piping system.
Pipe flanges can be attached to flexible connectors (metal hoses and expansion joints) in a number of ways, and it is important to recognize the advantages of each attachment style. First, a flange may be directly welded to the end of the hose or expansion joint, which is referred to as a “fixed” flange. This is the most basic method of attachment. It is important to note that a flange welded directly to a flexible metal hose may require a section of pipe (a “pipe spacer”) to be welded between the hose and the flange, in order for the assembly to conform to various piping code requirements.
If a hose or expansion joint has fixed flanges on both ends, it is critical that these flanges align properly with the mating connections. Otherwise, the connector may be twisted in an attempt to align the bolt holes during installation, creating torsional stresses that can damage the connector. The NAHAD Hose Safety Institute lists recommendations for proper bolt-hole alignment, which follows sound design practices and conforms to ASME’s Pressure Piping Code B31. If non-standard bolt-hole orientations are present, a good way to ensure proper alignment is to wait until the hose or expansion joint has been installed before welding the mating flange onto the adjoining piping system. This will ensure that the flange on the pipe will properly align with the flange on the hose end.
Another way to avoid flange misalignment is by installing a flange that rotates on the end of the flexible connector. These are referred to as “floating” flanges and come in various configurations. Floating flanges rotate without twisting the flexible connector, allowing the installer to align the bolt holes to the flange on the mating piping system. Once these floating flanges are in place and bolted to the mating flange, they no longer swivel. This means they cannot accommodate rotational movements after installation. If a rotating movement is required during operation, a properly designed swivel joint should be used to prevent twisting the flexible connector. For flexible metal hoses, flanges are installed onto a stub end, which is then welded to the hose. The face of the stub end becomes the sealing surface for a floating flange. Some stub ends are made by flaring a piece of pipe on one end; others are made by machining the stub end out of solid material. They can be made in various alloys and pipe schedules, and have different configurations that accommodate different flange types.
C-Stub with Floating Flange
While metal expansion joints may also contain floating flanges on stub ends, there is an alternative that provides a floating flange with a much more compact profile: Vanstone flanges. Vanstone flanges are attached directly to a metal bellows by slipping the flange over the unconvoluted skirt of the bellows (also called the “cuff” or “tangent”), and then flaring out the skirt to form a sealing surface over the face of the flange.
Vanstone flange connections take up much less length than stub ends, while still allowing the flange to rotate during installation. Because no welding is required for a Vanstone connection, it is a very economical means of flange attachment. However, the Vanstone connection may not be suitable for high-pressure applications, and require a special gasket, so due diligence is needed before these should be recommended.
Vanstone Flange Diagram
Not only do floating flanges compensate for bolt-hole misalignment in a piping system, they also isolate the flange from the media being conveyed. This means that a flange of a less expensive alloy may be allowed, as it does not come into direct contact with the material being conveyed.
There are many different flange specifications out there, and knowing which one to use can be confusing. It is not merely a “good idea” for any piping design to be reviewed by a qualified piping engineer or designer; failure to do so can lead to a catastrophic failure of the system. Once the proper flange style has been identified, the pressure class, alloy, method of attachment, gasket selection, nut/bolt specifications, and other factors must then be considered. This will ensure the flanged connections are safe and appropriate for the intended service.
