Stainless steel flange double ball rubber joint
Description
Stainless steel flange double ball rubber joint
Khớp nối chống rung cao su bụng kép bích inox
Khái niệm: khớp nối co giãn cao su bi kép là đầu nối linh hoạt được làm bằng vải và chất đàn hồi tự nhiên hoặc tổng hợp. Khớp nối cao su mặt bích bi kép bằng thép không gỉ được sử dụng rộng rãi trong các đường ống dẫn với các áp suất và phương tiện khác nhau. Sự tăng nhiệt, chuyển động của thiết bị, rung động hoặc dao động áp suất có thể gây ra chuyển động trong hệ thống đường ống. Khi chuyển động này không được hấp thụ bởi chính hệ thống đường ống, khớp nối cao su inox là giải pháp hoàn hảo.
Double ball rubber expansion joints are flexible connectors made of natural or synthetic elastomers and fabrics. Stainless steel double ball flange rubber joints are widely used in pipelines with different pressures and media. Thermal growth, equipment movement, vibration or pressure fluctuation may cause movement in the pipeline system. When this motion is not absorbed by the pipeline system itself, stainless steel rubber joints are the perfect solution.
Features: Vibration absorption, noise reduction, high pressure resistance, good elasticity, large displacement, balance pipe deviation, easy installation
- DIMENSION: DN32mm-DN800mm
- PRODUCT PRESSURE: 0.6-2.5 MPa
- WORKING TEMPERATURE:– 40 degrees to 80 degrees (can also process high temperature resistant rubber joints)
- SCOPE OF APPLICATION:acid, alkali, corrosion, oil, hot water, cold water, compressed air, compressed natural gas, etc.
PERFORMANCE
Reducing Fatigue Coefficient:
In view of the inherent characteristics of natural and synthetic elastomers, due to the steel and rubber interfaces of joints and flanges, they will not suffer from fatigue damage or embrittlement, and can prevent any electrolysis.
Excellent wear and corrosion resistance:
A wide range of natural, synthetic and special purpose elastomers and fabrics can be used by the industry. Processing and assembling of materials to meet various actual pressure/temperature operating conditions, corrosive erosion, wear and erosion.
Minimum Face-to-Face Size while Absorbing Large Motion:
Double ball rubber expansion joints have the smallest face-to-face length, providing excellent movement in the direction of axial compression, axial extension and lateral deflection, as well as in the direction of angle and torsion.
Due to the inherent flexibility of rubber, spring stiffness is low:
The inherent flexibility of double ball rubber expansion joints allows almost unlimited bending to recover from the imposed motion, requiring relatively small forces to move, thereby preventing damage to power equipment.
