Slip on plate flange is welded onto the end of a pipe and allows the pipe to be bolted to another pipe. It creates junctions through the bolt holes and by welding treatment. Slip on pipe flange is suitable for water or fuel pipelines with low pressure, few pressure fluctuation and little vibration. It is widely accepted because it enables an easy connection between the pipes and shows high price-performance ratio. Slip on flange helps users to save the space with its light weight structure, and most importantly, it guarantees an extremely-low leakage rate on the pipeline system with excellent sealing performance.

While slip-on plate flange can’t ensure a 100% seal because of its structural limit. What we can do is just to improve its’ quality and performance as much as possible. Yuanyang owns a full range of inspection equipment, such as optical emission spectrometer from SPECTRO, chemical analysis and testing center, fully automatic carbon/sulfur analyzer, high-speed analyzer, X-ray testing chamber, ultrasonic flaw detector, magnetic particle detector, infiltration detector, ultrasonic thickness gauge, computer-controlled electronic universal testing machine, 60-ton hydraulic universal tensile testing machine, low-temperature impact testing machine, metallographic analyzer, and infrared thermometer, etc.
