Description

Flat metal bending coil is normal to bend inner and outer rings of spiral wound gasket. Spiral wound gasket consists of basic body and metal inner and outer rings. The inner rings generally strengthen the basic body,so it is called the reinforcement inner rings. Because the fluid directly contact the inner rings,the quality of the inner rings materials is equal to or better than the basic body materials.The outer rings also called the locating rings have the function of orientation and fixation. The materials of outer rings generally handled by Q235 low carbon steel with galvanized or 304 stainless steel according to high requirements. For the selection of inner and outer ring generally according to the flange surface form and pressure.
