FIELD: process engineering.
SUBSTANCE: invention relates to device intended for mounting and centering of thin-wall shell end faces. Proposed device comprises two positioning mandrels with shaped guide bushes to center shells' outer diametres mounted on one guide base aligned with respect to diametre and axis to move axially thereon. Deformable circular plate-type heat exchanger consisting of separated lugs - lamels made from high heat conductivity material is arranged outside every centering guide bush with a certain gap there between with the help of attachment assembly.
EFFECT: higher quality of welded seam, simplified assembly.
