Type of Hose Assemblies Based on flexibility, the Annular corrugated hoses are categorized as follows according to ISO 10380-2003.

• Type #1: This type of hoses are highly flexible and is used for special application where high flexibility and fatigue life is required. The cyclic life is minimum 10, 000 cycles when subjected to short bend radius.
• Type #2: This type of hoses have moderate flexibility and widely used in Industrial application. The cyclic life is minimum 10, 000 cycles when subjected to wide bend radius.
• Type #3: This type of hose have low flexibility and is suitable for static applications . The cyclic life is 30 cycles and mostly used unbraided.

User Input requirements

• Size of the hose
Nominal bore size / Nominal size of connecting system / Length.
• End fitting details
Flanged / threaded / Welded / coupling, etc.
• Material
Material of hose, braid and fittings (SS 304/ SS 304L/ SS 316L/ SS 321. etc )
• Working pressure
Maximum pressure at extreme condition.
• Working temperature
Maximum temp. of fluid passing through or surrounding temperature.
• Installation details
May be explained by a simple sketch.
• Dynamic properties if any
Amplitude and frequency of movements, vibration etc. May be given by sketch.
• Fluid passing through the hose
complete specification of fluid with concentration, mixture, etc.
• Flow details
Velocity, Mass flow rate, density of fluid, etc.

Fittings for hoses are also supplied separately. Quality Foils [India] Pvt. Ltd. specializes in wide range of fittings including male hexagonal , full male union, female swivels, full female union , welding ends, threaded pipe nipples, elbow, stub, camlock coupling, flange [fixed and rotating] , welding collars etc in stainless steel and mild steel. Special fittings as per customer drawings and specifications can also be produced. The fittings are precision lathe machined or CNC machined as per requirement.

Bellows Manufacturing at world class quality with high technology to meet the various Industrial Application of customers requirements at all Technical aspects.Temperature withstand from -196 Deg to 1000 deg C and Pressure Ranges from Full Vacuum to 1000 PSI, Standards and it is an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement with out disturbing the inner flow media.

Metal wire braid on hose assembly restrain the hose elongation under pressure. Hence the force due to the internal pressure is transferred to the braid. Wire diameter and total number of wires are calculated to suit the pressure rating. A second layer of braid may be used to increase pressure rating.
Braid coverage is another important criteria. Less coverage leads to hose squirm under pressure while bending. Over coverage braid does not tighten the outer diameter of hose as there is clearance between them. Braid is designed to have optimum coverage.

Types of Braid
Tubular or Beam Braid:Tubular Braid is manufactured by grouping single wires and then braiding them into basket waive pattern that tightens when braid is stretched.

Grade

• SS 304 and SS 321 and SS 316 are also available subject to requirement.

The Quality Group is step up to another establishment of Metallic Bellows Manufacturing at world class quality with high technology to meet the various Industrial Application of customers requirements at all Technical aspects.
METALLIC EXPANSION JOINTS are designed as per EJMA Standards and it is an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement with out disturbing the inner flow media.
Type of Metallic Expansion Joints / Bellows
Circular Type:
