The invention relates to the by-product coking industry and concerns a packing assembly of units of gas risers. The assembly contains fishing piece, made in the form of flexible metal plate, connected along the inner perimeter with joint face of unit with bigger mirror, and along its outer perimeter, having fixed coupling, with superior face of effort distributor. The effort distributor is made in the form of metal condense frame, having along the whole its inner perimeter two parallel vertical faces, located on the underside, and space between them is filled with heat-insulation seal. The packing assembly also comprises device for blowing down, made in the form of barrels, installed with even pitch and rigidly attached to the unit with bigger mirror of hole, in which the spring-actuated subjacent rods are located. The invention provides for pressurization in the cases of changing of alignment of units of gas risers and deformation of theirs joint faces. |
