The metal bellow designed and manufactured by us at our state-of-the-art manufacturing unit. These bellows are made of high quality raw materials and are designed to handle highly abrasive metal. These metal bellows are available in different temperature, pressure and in shaft diameters.

We are manufacturer of pre-engineered rubber bellows to meet their individual requirements.Our strict manufacturing processes and quality control procedures insure a precise product every time. Single arc and double arc bellows are available in sizes 1" through 50" diameter. Rubber bellows can be made in most rubber compound.The rubber grades used for the inner and outer ply are empirically defined rubber compound rated to certain properties.

An expansion joint is a device used to allow movement in a piping system while containing pressure and the medium running through it. Frequently,thermal growth, equipment movement, vibration or pressure pulsation can cause movement in a piping system.When flexibility for this movement cannot be designed into the piping system itself, an expansion joint is the ideal solution.

FEATURES AND BENEFITS :

Absorbs All Directional Movement. Black Flex Wide arch and other styles of expansion joints provide superior movement capability in the axial compression, axial extension, lateral deflection as well as in the angular and torsional directions.

REDUCES NOISE AND VIBRATION

Black flex expansion joints effectively dampen and insulate against the transmission of noise and vibration generated by mechanical equipment. This is particularly important in HVAC application where the disturbing frequency of piping and fluid-conducted noise can resonate and amplify throughout the building.

HIGH RESISTANCE TO SHOCK

The compliant and resilient characteristics of black flex expansion joints make them ideally suited for Earthquake Isolation as well as Pressure-Surge and Water Hammer dampening.

RELIEVES PIPE AND ANCHOR STRESS

Thermal Expansion, along with other external forces and displacements including Ground Settlement, can quickly exceed allowable pipe and anchor stresses.

Largely used in various industries like automobile, engineering, petroleum and many other industries, the bellow manufactured by us are durable in quality. These bellows are precision engineered to deliver pressurized air in a specified and controlled manner. These bellows are easy to mount or dismount. We offer our range of bellows in a variety that includes fabric or rubber cover that is used for protecting machine slides.

Our Expansion Joints / Bellows are ideal solution for facilitating movement in piping system. We manufacture a variety of Bellows to suit the varied application. Our range includes: Stainless Steel Bellows Type Expansion Joints Rubber Expansion Joints ( Neoprene, Nitrile or any Synthetic Rubber ) Fabric Expansion Joints ( For Ducting) Teflon Expansion Joint (P.T.F.E) Features Provide superior movement capability in the axial compression, axial extension & lateral deflection Reduce noise & vibration generated by mechanical equipment that is particularly important in HVAC application where the disturbing frequency of piping and fluid-conducted noise can resonate and amplify throughout the building.

Have high resistance to shock that make them well suited for earthquake isolation as well as pressure-surge and water hammer dampening. Relieves pipe & anchor stress and replace them with their low products stiffness or reaction force.

Restrained Assemblies

Definition: Assemblies capable of restraining the pressure thrust of the system. Intermediate anchors are required to withstand the spring force generated when the expansion joint is deflected. The need for main anchors is eliminated.

Tied Single Bellows Assembly:

The addition of tie rods to a Single Bellows Assembly adds design flexibility to a piping system. The tie rods are attached to the pipe or flange with lugs that carry the pressure thrust of the system, eliminating the need for main anchors. With the assembly tied, the ability to absorb axial growth is lost. Only lateral and angular movement can be absorbed with the tied expansion joint. The addition of tie rods does not eliminate the need for a well-planned guide system for the adjacent piping.

Tied Universal Assembly: :

Similar in construction to a Universal Assembly except that tie rods absorb pressure thrust and limit movements to lateral offset and angulation. Large offset movements are possible in a Universal Assembly by increasing the distance between the two bellows.

Hinged Bellows Assembly: :

When a Hinged Expansion Joint is used, movement is limited to angulation in one plane. Hinged Assemblies are normally used in sets of two or three to absorb large amounts of expansion in high pressure piping systems. Only low spring forces are transmitted to the equipment. The hinge hardware is designed to carry the pressure thrust of the system, and often times, used to combat torsional movement in a piping system. Slotted Hinged Expansion Joints are a variant of the standard Hinged Expansion Joints that allow axial and angular movement. Be careful! Once a Slotted Hinge is introduced, torsion in the piping system is still resisted but the hinge no longer carries pressure thrust.

BLACK FLEX manufacture and deliver hose products ranging from 6mm through 300mm diameter.Complete hose assemblies are supplied with end fittings that are precision engineered to match either standard types, or created to specific customer designs.

A continuous working temperature range from -200C to 700C and suitability for conveying many chemically corrosive fluids, gives the BLACK FLEX stainless steel hose unrivalled performance.

Envied for their range of modern precision braiding machines, BLACK FLEX manufactures and stocks stainless steel braid from 6mm through 300mm nominal bore size DN. The strength and protection given to BLACK FLEX hose by single or double braid covering, is available for any other customers application.

Our hose product range consists of two types :

B-FLEX A close pitch hose with a high degree of flexibility and suitable for most metal hose applications.  1/4" (6mm) to 10" (250mm) nominal size DN.

C-FLEX A very close pitch hose with an exceptionally high degree of flexibility, a higher working pressure, and also often suitable for movement and vibration applications. 1/4" (6mm) to 6" (150mm) nominal size DN.

• Hose is normally supplied in Grade 321 S/S
• Braid is normally supplied in Grade 304 S/S
• Hose and Braid can also be Grade 316 S/S

Braid can be supplied separately if required or Customers hose can be over braided in our factory. We have one of the best braiding facilities available as we have 16,24,36,48,64, and even 96 carrier machines.

This gives us the ability to produce top quality Stainless Steel braid from 1/4" (6mm) to 12" (300mm) nominal size DN. Size 8 (200mm) nominal size DN and above are made as braided braid manufactured by initially weaving single steel wire into braid strands. These strands are themselves woven to form the final braid on our massive 96 carrier braider resulting in a highly stable and flexible construction.
