Rubber Bellows

Rubber Bellows
Features and Benefits:
 
ABSORBS ALL-DIRECTIONAL MOVEMENT
General Rubber’s 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. This is not obtainable with metal units or Large pipe loops. The low stiffness and deflection force make Designing with General Rubber Expansion Joint a breeze.
REDUCES NOISE AND VIBRATION
General Rubber Expansion Joints effectively dampen and Insulate against the transmission of noise and vibration Generated by mechanical equipment. This is particularly Important in HVAC applications 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 General Rubber Expansion Joints make them ideally suited for Earthquake Isolation,
As well as pressure-surge and Water Hammer dampening.
RELIVES PIPE AND ANCHOR STRESS
Thermal Expansion, along with other external forces and Displacements, including Ground settlement, can quickly exceed Allowable pipe and anchor stresses. General Rubber Expansion Joints absorb these stresses and replace them with their low Product stiffness or reaction force.
COMPENSATES FOR MISALIGNMENT
It is common in both new construction and replacement Applications to encounter piping misalignment. Minor misalignment Can be taken up with standard General Rubber Expansion Joints And custom units can be fabricated for large offsets.
COST-EFFECTIVE SOLUTION
An optimal design does not necessarily mean higher pressure or Temperature ratings, because these features increase the unit’s Stiffness and cost. General Rubber will work with your system Requirements and with over 50 years of experience, they feel Confident in developing an optimal and cost effective solution. The abrasion-and corrosion-resistant rubber can be superior to Even the most exotic metals. Large inventories and a modern U.S. manufacturing facilities also mean quick deliveries.

CONSTRUCTION MATERIALS
EPDM – outstanding water, vapor, and weather resistance. Good resistance to heat, ozone, alkalis, sunlight, and oxygenated Solvents. Ideal for outdoor service. Do not use for petroleum oil Service. Good general-purpose elastomer for an effective operating Range from -30F to 300F.
PURE GUM RUBBER – Excellent resilience and rebound elasticity With high tensile strength. Excellent resistance to tear and abrasion. Effective operating range from -40F to 180F.
VITON – Resists permeation by aggressive chemicals, solvents, And halogenated hydrocarbons; helps to control fugitive emissions.
Good resistance to ozone, oxygen, and weathering. Effective operating range from 0F to 400F.
TEFLON – superior chemical resistance, completely inert to Nearly all industrial chemicals and solvents. Effective operating Range from -60F to 450F.
FDA FOOD-GRADE SERVICE – several white and black Elastomers meet FDA requirements and can be used in direct Contact with food, beverage, and pharmaceutical products.
REINFORCEMENTS – polyester, nylon, Kevlar, fiberglass, And steel. Temperature rating is dependent on both elastomer And reinforcements.

HANDLING YOUR TOUGHEST APPLICATIONS SINCE 1950.
POWER GENERATION
General Rubber Expansion Joints are used on condenser water Boxes, cooling towers, steam turbine exhaust lines, cooling Water lines, scrubber units, and FGD systems.
WATER AND WASTE TREATMENT
Flexible connections are required on sludge and grit pumps, Digesters, aeration systems, blowers, odor control, and methane Gas ducting.
CHEMICAL PROCESSING
Expansion joints of Teflon and other chemical-resistant materials Are required on caustic chemical pumps, digesters, scrubbers, And are found throughout the piping and ducting system.
PAPER AND PULP
Bleaching systems and lines containing white, black, and green Liquors require chemical-resistant expansion joints along with The pulp slurry pumps and scrubber units.
HVAC
Pump connector and other expansion joints designs will reduce Noise and vibration generated from mechanical equipment, Including pumps, chillers, compressors, fans, heat exchangers, And cooling towers. They are also used to absorb thermal Movements in risers and other pipelines.
MINING
The extremely abrasive slurry in tailing lines requires Pure Gum Rubber expansion joints. The ducting also Often requires chemical-resistant flexible connections.
MARINE
Shipboard piping and ducting utilize neoprene connectors built To coast guard, ABS, and ASTM F-1123-87 standards.
