Big size Steel flange

　　Big size steel flange normally is Slip-On flanges.  Diameter can up to 6 Meters. The size over 2 meters is called huge flanges. This kind of flanges is too big, so hard to be delivered.  We usually divided the flanges into several parts then after arrived at the spot they weld them together. But for some clients and project this way is not alloyed. So we have to delivery them in a whole. It will cost more transport cost in home and abroad. And it can not put into the container directly.
