Features and Benefits of our Reducing rubber connectors
• Absorb Pipe Movement/Stress,
• Reduce System Noise,
• Isolate Mechanical Vibration,
• Compensate Alignment/Offset,
• Eliminate Electrolysis,
• Protect Against Start-Up Surge Forces
Features and Benefits of Songxia Products:
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.
NOTES:
1. Pressure rating is based on 170oF operating temperature. The pressure rating is reduced at higher temperatures.
2. Pressures shown at maximum “operating pressure”. Test pressure is 1.5 times “operating pressure”. Burst pressure is 3times “operating pressure”. If factory hydro-test is required, an additional joint per size must be purchased and tested. Once hydro-tested this joint may not be sent to field for installation as the beaded end will have taken a (compressed) set and can not be reused.
3. In addition to standard 150 lb. drilled flanges, Proco can provide expansion joints listed above in 300 lb. drilling, BS-10 (British) drilling, Metric PN10 and PN16 drilling and JIS 10kg/cm drilling.
