Abstract

800,348. Pipe couplings. DALMINE SOC. PER AZIONI, and PEZZOTTA, G. June 23, 1955 [May 12, 1955], No. 18171/55. Class 99(1). In a coupling for tubular elements A, B each provided with a conical screw-threaded portion and including at least one packing C acted upon by the pressure of the fluid carried by the elements to effect fluid sealing of the coupling, there is a cylindrical portion 1, 1<SP>1</SP> and 2, 2<SP>1</SP> at each end of each screw-threaded portion and coaxial therewith, those cylindrical portions co-operating with the packings C which are housed in annular grooves. As shown in Fig. 1, the packings C are circular in crosssection and disposed in grooves formed respectively in the portions 1<SP>1</SP>, 2 ; alternatively, the grooves are provided in the portions 1, 2<SP>1</SP>. In modifications, the elements A, B are connected by an externally screw-threaded sleeve D, Fig. 2, or an internally screw-threaded sleeve.
