Abstract
Modular rectangular parallela pipidle sealing units assembled in a frame for a gas tight penetration seal have perimetral grooves and bores reaching from these grooves into the recesses of the modules to the peripheries of the cables or pipes or filler bodies in the modules. The grooves and bores form a pressurizable network which after pressurization with compressed air can be monitored for gas tightness.

A modular penetration seal for a sealed passage of cables and pipes through structures of all kinds, comprising at least one seal module having two block-shaped parts each formed with a semicylindrical recess and into which selectively a member selected from a cable, a pipe and a filler body can extend in a longitudinal direction and can be sealingly engaged, each module having external sealing surfaces formed with grooves transverse to said longitudinal direction, at least one bore being formed in said module in at least one of said grooves and reaching into said module to an outer surface of said member.
A method of providing a penetration seal in the form of a gas-tight bulkhead in a structure, comprising the steps of:
- (a) providing a plurality of seal modules each having two block-shaped parts formed with semicylindrical recess and into which selectively a member selected from a cable, a pipe and a filler body can extend in a longitudinal direction and can be sealingly engaged, each module having external sealing surfaces formed with grooves transverse to said longitudinal direction, at least one bore being formed in each said module in at least one of said grooves and reaching into said module to an outer surface of the respective said member;
- (b) assembling a plurality of said modules in a frame with said modules sealing against one another and against said frame so that said grooves and bores form an internal network defining a test volume sealed against the exterior;
- (c) from the exterior pressurizing said network with compressed air;
- and
- (d) measuring pressure loss from said network to ensure gas-tightness of the penetration seal.
