管法兰及其垫片、紧固件统称为管法兰接头,管法兰接头是有机热载体炉安装中必不可少的零件。尽管管法兰接头选择时满足了《有机热载体炉安全技术监察规程》的要求,即采用公称压力不小于1.6MPa的平焊钢法兰,其垫片采用金属缠绕式石墨垫片或膨胀石墨复合垫片,但是在有机热载体炉系统中由于各种原因引起的泄漏仍普遍存在。影
Pipe flanges and their gaskets, fasteners collectively referred to as pipe flange joints, pipe flange joints are organic heat carrier furnace installation is an essential part. Although the selection of pipe flange joints to meet the “organic heat carrier furnace safety technology supervision regulations,” the requirement that the nominal pressure of not less than 1.6MPa flat welded steel flange, the gasket using metal-wound graphite gasket or expanded graphite Composite gaskets, but leakage in organic heat carrier furnace systems is still common due to various causes. shadow
