Kit Standard
Certified penetration for every vessel
Designed for any exhaust pipe at high temperature. Compact and easy to install, it reduces heat dispersion on the surrounding surface. Delivered pre-assembled, one weld, certified. Delivers A60 fire resistance up to 1,000 °C for 60 minutes.
How a hot pipe penetration works
What is Kit Standard?
Kit Standard is Hell-Sea's core welded penetration, built for a straight exhaust pipe run through a bulkhead or deck where the flange doesn't need to move or unclamp later. It ships as one pre-assembled unit (outer ring, inner ring, and a fireproof and watertight special braid that seals the passage), so the yard closes it with a single welding operation instead of building an insulated trunk on site. A traditional insulated trunk radiates heat across a much larger surrounding surface, while Kit Standard's compact profile confines the fire barrier to the penetration itself. In an in-house 24-hour test on a DN200 exhaust penetration, heat on the deck 30 cm from the penetration was reduced by up to 90%. It carries the full A60 rating (1,000 °C for 60 minutes) and 2 bar watertight integrity for 60 minutes simultaneously, across the entire DN32–DN1000 range, so the same certified design scales from a small generator exhaust to a large FPSO stack without re-engineering. Steel and aluminium hull variants are both available from stock. Choose Kit Standard when the pipe run is fixed and known before fabrication; if the flange orientation isn't decided yet, Kit Rotary is the better fit, and if there's no existing flange to weld to, Kit Slim's V-Band connection avoids welding entirely.
