FIELD: mechanics, pipelines. ^ SUBSTANCE: invention relates to pipeline transportation and can be used in repair of pipelines. The pipe sleeve surface intended for radial gaps of welding joints furnished with an axial stop symmetric about two equidistant sections of glass fabric. The sleeves with opposed tapered ledges and circular stops arranged there behind allow arrangement of glass fabric sections along the circular perimeter. The tapered sections, the most distant from the stop, are furnished with annular collars arranged on the sleeve outer surface and intended for axial movement of self-hardening paste inside end face section of pipeline being jointed together. The glass fabric surface accommodate half-rings and repair sleeve assembly. ^ EFFECT: wider range appliances for jointing pipelines together. ^ 1 dwg
