Abstract

Closure cap, has a center opening with a guide for a cutting tool prong to clear the end of the pipe for welding. The closure cap, for the end of a steel pipe with a plastics cladding, is removed and the plastics stripped away when pipes are welded together. The cap has a center opening for the insertion of a cutting tool prong. The cap has a clamping/centering section (11), a disk-shaped section (12) and a guide cone for the inserted cutting prong (13). The cap has grooves (15) to hold O-rings, and the cap diameter (14) matches the end of the pipe.
