• Operating Temp: -60°C to +200°C (-76°F to +392°F).
• Application: Perfect for highly corrosive chemical processing and acid transmission.
Rubber-lined Piping (Pipe Fittings)
• Lining Material: Premium anti-abrasion and anti-corrosion Natural Rubber / NBR / EPDM.
• Shell Material: Heavy-duty Carbon Steel structure with high structural stability.
• Features: Outstanding wear resistance, vibration damping, and noise reduction.
• Ideal For: Slurry transport, mining systems, desulfurization, and water treatment.
Fabric Belt
• Multi-Layer Structure: Premium PTFE coating, high-tensile fiberglass cloth, and silicone layers.
• Temp Resistance: Handles extreme gas temperatures up to 1000°C based on composition.
• Performance: Exceptional multi-directional movement absorption and high chemical stability.
• Application: Industrial flue gas ducts, power plants, and ventilation systems.
(Fabric Expansion Joint) Rectangular
• Geometry: Customized Rectangular design tailored to fit specific duct dimensions.
• Material System: Multi-layer composite fabric with robust steel backup flanges.
• Features: Zero internal stress transmission, excellent flexibility, and low structural weight.
• Application: Hot air ducts, fan inlets/outlets, and environmental desulfurization systems.
(Fabric Expansion Joint) Round
• Type: High-flexibility Round Fabric Joint for large-diameter circular piping.
• Shell & Fabric: Multi-layer specialized cloth combined with robust steel welding sleeves or flanges.
• Benefits: Absorbs huge axial and lateral movements in low-pressure ducting networks.
• Application: Power generation, waste gas treatment, and chemical exhaust pipelines.
Rectangular Duct Expansion Joint
• Shape: Specialized Rectangular configuration engineered for industrial ducting networks.
• Options: Available in both high-flexibility rubber matrices and metallic bellows structure.
• Function: Compensates thermal expansion, structural misalignment, and system vibrations.
• Application: HVAC ducts, dust extraction systems, and industrial ventilation lines.
Round Duct Expansion Joint
• Design: Circular design tailored for low-pressure gas pipelines and air blower networks.
• Material Choice: Tough EPDM/Silicone matrices or Stainless Steel corrugated bellows.
• Advantages: Minimizes structural noise, limits pipe fatigue, and ensures long-term seal tightness.
• Application: Aeration piping, gas exhaust systems, and cement plant air ducts.Dismantling Joints (C2F)
• Structure: Heavy-duty rigid carbon steel body with high-tensile adjusting full-thread rods.
• Design Standard: Compliant with international piping regulations for valve installation.
• Key Function: Provides quick adjustability for simplified valve installation, maintenance, and removal.
• Application: Large-scale water supply systems, pumping stations, and industrial fluid loops.
