Rubber Bellows specifications required in manufacturing
In India, manufacturing of Rubber Bellows are required exact technical specifications to ensure they absorb vibration, handle pressure and compensate for pipe or machinery movement properly. Key parameters include dimensions, material compounding, reinforcement layers and operating limits. Details with technical data is described below :
Nominal Bore (NB) or Inner Dia. (ID) : It is variable widely by application, ranging from small mechanical and machinery dust boots (10 – 100 mm.) to large industrial pipe lines (40 – 2000 mm.). Measuring the exact NB or ID requires matching the inner opening to your specific pipe, shaft or housing diameter. We can supply with up to – Round : 2 meters, Square : 4 meters & Rectangular : 3 X 4 meters.
Bellow length : It has standard end to end measurement that based on both side pipe gap where the Bellow will fit. To measure the accurate length, use a tape measure or caliper to find the neutral length. Also record the compressed length, extended length. We offer Bellows up to 1000 mm. of natural length.
Bellow shape : Round, Square and Rectangular are normally used. It is depends on application, the type of motion it needs to absorb (axial / lateral / angular) and the geometry of the equipment or pipes to protect. Our supply range for Round is 2 meters, Square is 4X4 meters and Rectangular is 4X3 meters.
Working Temperature : It is typically ranges from -40° C to 120° C but the exact limit depends heavily on the specific elastomer compound used in it’s construction. Standard general use Bellows use around 70° C to 100° C, while specialized high performance rubber types can tolerate higher or lower extremes. This is to determine by the system’s actual operating and peak fluid temperatures and match them against the explicit thermal limits of the elastomer compound used in the Bellow. We can manufacture up to 150° C.
Working Pressure : It’s typically operate at 10 bar to 16 bar at ambient temperature, with heavy duty or specialized designs reaching up to 25 bar. It is a manufacturer rated limit determined by fabric reinforcement, elastomeric compound strength and burst test safety factors. Our supply capacity is up to 45 Kg. / cm².
Flange Outer Dia. : The integrated metal flange depends directly on its nominal bore size and the matching pressure standard. For instance, a small 40 NB Bellow often has a flange outer diameter around 90 – 120 mm., whereas a larger 1000 NB Bellow features an outer flange diameter of at least 600 mm. Our supply range is up to 1500 mm.
Rubber grade : It is generally use different grades of rubbers based on environment, chemical exposure, temperature range, mechanical movement requirements and the fluids or gases passing through them. The most common grades we use – Neoprene, EPDM, Natural, Silicon, Hypalon, Nitrile, Buna-N, NBR etc.
Flange material : It is used metallic or integrated rubber flanges for pipeline attachment. Common metallic flange materials include Carbon Steels – ASTM A105 / A105N, ASTM A36, ASTM A350 LF2, ASTM A694, ASTM A516 etc. for standard water and HVAC applications and Stainless Steels – SS 304 / 304L, SS 316 / 316L, SS 321, SS 347 / 316Ti etc. for corrosive environments or hygienic processes. Some designs also feature full face integrated rubber flanges.
