Products and services

The SB Broneske company founder developed the first modern vibration mount for the (German) shipbuilding industry. The specially designed fixed point vibration mounts combine reduction of structure-borne noise and heat resistance.

The company’s product range includes vibration mounts, expansion bellows, pipe penetrations, rain caps, exhaust flaps. The flexible deck/bulkhead penetration is the world’s first fire- and watertight pipe penetration. SB Broneske has developed the product lines Basic Silent, Super Silent and Super Silent Plus for specific projects and offers detailed installation and production drawings for the correct ship structure.

The elastic support specialist features customized technical developments (e.g. vibration mounts for heavy or low loads, penetrations made of fiberglass) and individual design support (e.g. turn over solutions or funnel top solutions). SB Broneske opened up the new business unit LNG and offers LNG certified components for LNG piping systems.

SB Broneske Vibration Mounts

SB Broneske Vibration Mounts

SB Broneske vibration mounts combine heat resistance and elastomeric reduction of body sound. Because of being designed with a special highly effective heat resistant elastomer, they stand out due to heat resistance up to 300° C. Furthermore, they are shear- and fire-proof and very effective in reducing vibrations and structure-borne noise. The vibration mounts are available with load from 1 kg to 100.000 kg and specially designed for the exhaust pipe system of ships.

SB Broneske Flexible Deck / Bulkhead Pipe Penetration

SB Broneske Flexible Deck / Bulkhead Pipe Penetration

The SB Broneske flexible pipe penetration is the world’s first penetration that is water- and fire-proof and certified for deck and bulkhead. It is capable of withstanding temperatures of 1000°C for 60 minutes (A-60) and waterproof for 30 minutes (6m, 0.6bar).

The exhaust gas pipe penetration is accredited with an European MED-A-60, US Coastguard, LR Type Approvals, DNV GL Type Approval, ABS Design Approval and Bureau Veritas Type Approval. It is popular with all kinds of passenger vessels and luxury yachts.

SB Broneske Expansion Bellows

SB Broneske Expansion Bellows

Compensators are a necessary component in many industries because they compensate the thermal heat expansion of the pipe sections. SB Broneske expansion bellows are well known in the maritime industry for their outstanding quality. SB Broneske has been calculating and delivering expansion bellows to shipyards worldwide since the 80s of the last century and offer stainless steel and rubber expansion bellows. The calculations / designs for the expansion bellows are supplied free of charge.
