Abstract

1449912 Making T-pieces; stamping J B SKIBILD 28 Jan 1974 [6 Feb 1973] 3759/74 Heading B3A, B3Q [Also in Division F2] A tubular tee element is made by placing a tube 2 of stainless steel in a tool 6 with a cylindrical rubber body 10 inside the tube, the rubber body being subject to the action of a pressing plunger 12 so as to push out part of the tube wall into a recess 8 in the tool and to form a bulge 14, the tube 2 then being removed from the tool 6 and after formation of a hole (not shown) in the bulge 14, being placed in another tool 18 and subjected to another pressing operation wherein the bulge walls will be. straightened out into a bore 20 to form a branch tube stud 22, the tee element then being completed by fitting a further length of stainless steel tube over the stud 22 and welding this in place. A liquid may be used in place of the rubber body 10 and in some instances the formation of the hole in the bulge 14 may be unnecessary or the formed tube stud 22 may itself constitute the branch tube without the fitting of a further length of tube. Grooves, as 30, may be formed during the pressing operation for accommodation of sealing rings if desired.
