Steel Industry - Rubber Bellows & Expansion Joints for Steel Plants
Steel plants operate in extreme heat, heavy dust, and constant vibration. Pipelines carrying blast furnace gases, cooling water, and fume extraction ducts expand and contract every day. Without flexible joints, you get cracks, leakage, and unplanned shutdowns.
Aphrodite Polyprene Pvt. Ltd., Kolkata, manufactures heavy-duty Rubber Expansion Bellows specifically engineered for the Steel Industry. Our bellows absorb axial, lateral, and angular movements while isolating vibration from mills, ID fans, and rolling lines.
Applications in Steel:
- Hot blast and cold blast mains
- BF gas cleaning pipelines
- Water-cooling lines for continuous casting
- Dust extraction and fume ducts
- Descaling pump discharge
Why Steel Plants Choose Us: High-temperature EPDM/Silicone construction, reinforced with fabric & steel wire, size range DN 50 to DN 3000, custom drilling as per plant layout. Zero-defect supply for SAIL, TATA Steel vendors.

Power Industry
Expansion Joints for Thermal & Nuclear Power Plants
Power plants cannot afford pipe failures. Steam lines at 540°C and 4.2 MPa expand several centimeters. Our Expansion Bellows are the unsung heroes that absorb this thermal expansion and protect turbines, boilers, and condensers.
Aphrodite Bellows supplies both Metallic and Rubber Expansion Joints for Power Generation – for LP/HP steam lines, circulating water lines, and exhaust ducts.
Applications in Power:
- Steam turbine bypass & exhaust lines
- Boiler feed pump pipelines
- Cooling water & CW pump discharge
- Flue gas ducts & ESP connections
- District heating take-offs
Specification: Metallic bellows in SS304/321 with 16-bar rating, Rubber bellows in EPDM for cooling water up to 180°C. Designed as per EJMA standards, hydro-tested and DP-tested.

Oil & Gas Industry
Expansion Joints for Refinery & Offshore
In Oil & Gas, pipelines face high pressure, corrosive media, and platform movement due to waves and temperature. A rigid pipeline will fail. Aphrodite Polyprene provides Oil Resistant Rubber Bellows & Metallic Expansion Joints for onshore refineries and offshore supply lines.
Applications in Oil & Gas:
- Crude oil & product transfer lines
- Offshore supply line from platform – 204-EXP type
- Petrochemical feedline to process
- Slop oil and flare lines
- Sea water intake for cooling
Why Us for Oil & Gas: Nitrile (NBR) and Viton lining for oil resistance, control rods & tie-rods for pressure safety, SS316 flanges, 24″ to 72″ custom builds, on-time dispatch to Haldia, Paradip refineries.

Chemical Industry
Chemical Resistant Bellows for Corrosive Media
Chemical plants handle H2SO4 98%, HCl, NaOH 30% Caustic, and corrosive vapors. Standard bellows fail in months. Our Chemical Resistant Rubber Bellows are built with special linings to handle corrosive acid lines, alkali treatment tanks, and process flow.
Aphrodite bellows are installed in Acid Storage Tank lines, Corrosion Monitoring Panel connections, and pH meter interlocks.
Applications in Chemical:
- Acid transfer DN100 & DN150 lines
- Alkali treatment and NaOH lines
- Effluent treatment plants (ETP)
- Chlor-alkali plants
- Pharma & fertilizer process piping
MOC Options: Natural Rubber with Butyl / EPDM / Neoprene lining, PTFE lined metallic joints for highly aggressive media. Each joint tagged with process details and inspection date.

District Heating Industry
Large Diameter Expansion Joints
District heating networks run kilometers of hot water at 130°C-150°C underground. Soil movement and thermal cycling cause huge expansion. Our Dog Bone / Belt Type and Large Fabric Expansion Joints absorb this and prevent city heating failure.
Applications:
- Underground pre-insulated heating pipes
- Heat exchanger stations
- Boiler house headers
- Urban heating distribution network
Aphrodite supplies dismantling joints for easy maintenance in district heating chambers. Available up to 3000mm diameter.

HVAC Industry
Vibration Isolation Bellows for HVAC
HVAC Rubber Expansion Joints – Vibration Isolation for Chillers & AHU
HVAC systems fail not due to heat, but due to vibration from chillers, pumps, and cooling towers. Our HVAC Rubber Bellows isolate vibration, reduce noise, and absorb small movements in commercial buildings, malls, and hospitals.
Applications in HVAC:
- Chiller pump suction & discharge
- Cooling tower pipelines
- AHU coil connections
- Air conditioning duct expansion joints
- Firefighting pump lines
Lightweight, easy to install, no need for gaskets. Reduces maintenance cost and extends equipment life.
