CA 2334717
An account has been made for a thread cleaning and lubricating device in the form of a high pressure washing device (16, 18, 20, 22, 24, 12) for cleaning external/internal threads of pipe end couplings, and equipped with a mechanism (16', 18', 20, 22', 24, 12) for applying fat under pressure on said threads. A nozzle head's main body (10) is formed with two separate annuli (14, 14') for the supply of cleaning liquid under high pressure or thread-fat under pressure, respectively. In order to arrange the conditions for a uniform cleaning process across the entire thread portion and an even application of thread-fat, and for simplifying and facilitating the centring of respective pipe end's socket/tap end in relation to the axis (50) of the nozzle head/body (10), each annulus (14, 14') has a 360~ encircling discharge slot opening (26, 26').
L'invention porte sur un appareil de nettoyage et de graissage de filets comportant un dispositif de lavage sous haute pression (16, 18, 20, 22, 24, 12) des filets intérieurs et extérieurs des raccords d'extrémité de tiges de forage, et un mécanisme (16', 18', 20', 22', 24', 12) appliquant de la graisse sous pression sur lesdits filets. Le corps principal (10) de la tête d'injection présente deux chambres annulaires séparées (14, 14') amenant respectivement le liquide de nettoyage sous pression, et la graisse sous pression. Pour permettre un nettoyage uniforme de la totalité des filets et une application régulière de la graisse, et simplifier et faciliter le centrage des douilles d'extrémité des tiges et des extrémités des tarauds par rapport à l'axe (50) du corps et de la tête d'injection (10) chacune des chambres annulaires (14, 14') présente une fente de décharge circulaire sur 360· (26, 26').
