The Flat Face Flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.
Flat face flanges are never to be bolted to a Raised Face Flange. ASME B31.1 says that when connecting flat face cast iron flanges to carbon steel flanges, the raised face on the carbon Steel Flange must be removed, and that a full face gasket is required. This is to keep the thin, bittle cast iron flange from being sprung into the gap caused by the raised face of the carbon steel flange.

The microprocessor controller of the automatic warp machine is used for data exchange between the warp machine and the rack. Data is transmitted and converted through a dedicated channel. The sensor mounted on the warping machine continuously measures the tension of the upper and lower layers through the skein and sends the obtained data to the microprocessor; then compares the actual measured value with the set value and immediately sends the offset value to the machine. frame. The frame is adjusted to the set value by the servo motor.
The good cooperation of the various components of the equipment allows the machine to achieve reliable knotting, and the knotting process is completely automatic, and the good knots also reduce the needs of personnel.
