Detailed Product Description
rubber coupling connector:
1.DN25~3200mm
2. Flange Standard: GB, DIN, JIS, ANSI;
3.Joint Pipe Rubber Flexible Material: NR, NBR, EPDM;
4.Pressure:10bar, 16bar, 25bar, 40bar;
Features and Benefits:
1. Absorbs Directional Movement
Thermal movements appear in any rigid pipe system due to temperature changes. The spherical arch expansion joints allow for axial compression or axial extension, lateral deflection as well as angular movement.
2. Easy Installation with Rotating Metallic Flanges
The floating metallic flanges freely rotate on the bellows, compensating for mating flange misalignment, thus speeding up installation time. The expansion joints are mated against a flat face flange as required in the installation instructions.
3. Flange Materials/Drilling
The rubber expansion joints are furnished complete with plated carbon steel flanges for corrosion protection. 304 or 316 stainless steel flanges are available upon request as well as ANSI 150/300 lb., BS-10, DIN PN10 & PN16 and JIS-10K drilling.
4. Absorbs Vibration, Noise and Shock
The expansion joints effectively dampen and insulate downstream piping against the transmission of noise and vibration generated by mechanical equipment. Noise and vibration caused by equipment can cause stress in pipe, pipe guides, anchors and other equipment downstream. Water hammer and pumping impulses can also cause strain, stress or shock to a piping system. Install the rubber expansion joints to help compensate for these system pressure spikes.
5. Material Identification
All rubber expansion joints have different medium designing. Based on the use of environmental requirements and customer needs, rubber joints can be produced with a lot of material, such as Chloroprene rubber (CR) and acrylonitrile-butadiene rubber (NP), ethylene propylene diene monomer (EPDM).
6. Large Inventory
SONA Products, we maintains one of the largest inventories of rubber expansion joints in the world. Please contact us for price and availability.
