non-standard flange
PIC-(non-standard flange)
So-called non-standard flange, it is almost no pressure to above the pipe, so asking how many kilograms of flange also need not able to withstand pressure, there is only one goal: the price is cheap.General non-standard ferrari are five mm outside diameter small size, small 10 mm thick, also have in pursuit of cost minimization, thinner thickness requirements of customers, non-standard applications the most places is the mine drainage facilities.Such facilities without pressure, flange is a basic connection effect.
Non-standard flange price is low, but must not be used in the engineering of pipeline pressure requirements, otherwise easy to cause safety accidents, resulting in loss of persons or property.
