Fluid, once leakage, which occurs, will result in loss, the loss of economic aspect is not only resulted in, it is serious to cause big safety
Accident.Therefore most important to the detection of pipe fitting and connector.
Round pipe fitting or pipe component are detected it is necessary to be blocked and tested to it, and round pipe fitting or circle
Duct member is a large amount of in daily production, therefore the speed for blocking and testing when detection is extremely important to production efficiency.
Existing market upper pipe fitting blocks when detecting and the open end to pipe fitting, glue are filled in test using rubber stopper or rubber tube manually
Plug or sebific duct internal diameter are bigger than the internal diameter of pipe fitting than tube outer diameter is small or its outer diameter, can just reach reliable sealing in this way.
Such slow efficiency of mode speed is low, the quick abrasion of rubber plug and sebific duct.Another kind blocks and detection mode is to use hand-operated clamping
The Connect and Choke Plug of sealing, this slow efficiency of mode speed is low, and the worker that works long hours is easy fatigue.
