Pyrotechnic Tube Cutters
Most often our tubing cutters are designed to open pressure diaphragms or to completely sever and then seal metal tubes of varying diameters and wall thicknesses which may be carrying pressurized fluids. The tubing cutter/sealer is used to cut and seal two stainless steel (which can be Teflon lined) tubes. The tubing cutter/sealer assembly primarily consists of the body, anvil, one electrically fired gas pressure cartridge, four shear pins and cutter assembly. The cutter assembly consists of the piston, crimper and blade. The crimper and blade are attached to the piston by two of the shear pins, (sequencing pins). The piston is secured in the body by the other two shear pins, (initial lock pins). The body provides for the installation of the cartridge, attachment of the anvil, and housing for the cutter assembly. Lugs, for attaching the tubing cutter/sealer to the releasing structure, are an integral part of the body.
