Beschreibung
Zusammenfassung:	The invention relates to a threaded pipe joint comprising internal and external mating members with conical surfaces, on which threaded portions having the general surface profile of a frusto-conical shape are formed, wherein radial sealing surfaces forming a radial sealing unit and end-face sealing surfaces forming an end-face sealing unit are provided on the internal and external mating members from the side of the smaller diameter of the frustrum, wherein the internal mating member has at least one threadless portion, on which the radial sealing surface is located, characterized in that the threadless portion of the internal mating member, on which the radial sealing surface is located, is configured with enhanced thickness such that the generatrix of the radial sealing surface is located higher than the thread root line by a value of δ in range from 0,60 to 0,9 mm, and the number of full-crest turns on the internal mating member engaged with the counter-turns of the external member is 6-10 turns.
