How is the amount of flanged piece calculated in the fire pipeline?
The flanges of fire pipes are the units of the eighth volume. The Flange is called a Flange or a Flange. The flange is the part of the pipe that connects the pipe to the pipe. There are bolt holes in the flanges, and bolts make the two flanges. The flange is usually sealed with a gasket (flange gasket). 3, fire pipeline as the name implies is to establish the pipeline system, fire due to the special demand, the thickness of fire pipeline materials have special requirements, and red paint, fire water.
Pipe flange connection: the flange installation is usually included in the pipe flange connection installation quota, the main material of the flange and the bolt; If there is no flange connection quota, the thread connection quota should be set first, then the flange installation quota. 3, flanged flanges in the pipeline or interface pipe: the set flange is fixed; Both the 6th and eighth volumes in liaoning have flange installation quotas;
Flanges on the valve: the set of the sixth volume, valve, flanged separately, valves, bolts and flanges; When the eighth volume is set, the flanges and bolts are auxiliary. I am liaoning, the seventh volume of liaoning quota also has valves, flanges and bolts are also auxiliary materials. If it is a groove flange, simply replace the main material or auxiliary material
