METHOD AND DEVICE FOR MANUFACTURING OF INSULATING PIPE SECTION FROM MINERAL WOOL
FIELD: construction industry. ^ SUBSTANCE: according to presented method for forming of, actually, cylindrical insulating blank, cotton-wool is supplied in form of loose material to spacing between core and, actually, cylindrical external form enclosing core. For fixation of form of pipe section blank its inner and outer surfaces are heat-treated by means of heating of at least part of core and external form. Then processing of unprocessed layer located between processed inner and outer surfaces is performed. Forming device contains area of pipe section formation, this area consists of core and, actually, cylindrical external form enclosing it, and also of device for final thermal processing of formable pipe section. ^ EFFECT: invention provides continuity of process of pipe section forming, absence of waste material, it allows to change length of product depending on customer's requirements. ^ 28 cl, 3 dwg
