Product description
“Roxtec RS and RS PPS/S sealing systems for pipes (Back-to-Back Arrangement)”
RS Sealing and RS PPS/S sealing systems consist of two seals installed in both sides of an extended
sleeve or frame (minimum 600 mm) generating a “back-to-back arrangement”. The sleeve or frame
shall have a centred position in the bulkhead, and be welded to it.
“Roxtec RS PPS for pipes (Back-to-Back Arrangement)”
RS PPS sealing system consist of two seals installed in both sides of an extended sleeve or frame
(minimum 700 mm) generating a “back-to-back arrangement”. The sleeve or frame shall have a centred
position in the bulkhead, and be welded to it. Two reels of intumescent material arranged within the closed
void inside sleeve, positioned at each side of sleeve/seal.
Insulation for A-0 to A-60 has to be arranged based on already approved documentation, and according
to the drawings mentioned under Type Examination documentation below.
Application/Limitation
The systems are tested for watertightness with 2 bar test pressure for 30 minutes after a 60 minutes fire
test with the following results:
| Pipe system size | Pipe outer | Type of pipes | Approved |
|---|---|---|---|
| diam. | pressure (bar) | ||
| RS 43-150 (BTB) | 16 – 114.3 mm | Steel pipes | 1,33 no leakage |
| RS 31-150 (BTB) | 10 – 108 mm | Copper pipes | 1,33 no leakage |
| RS PPS/S (BTB) 43 -150 | 16 – 110 mm | Thermoplastic pipes: | 1,33 no leakage |
| PVC, PP, PVDF, PB | |||
| RS PPS/S (BTB) 43 -150 | 16 – 114 mm | Thermoplastic pipes: | 1,33 no leakage |

This certificate for back-to-back arrangements does not replace the need of having valid fire safety type
approved certificates for the corresponding rated single penetrations.
Application for passengers and SPS vessels
Penetration system acceptable for use in watertight bulkhead divisions on passengers and SPS vessels in
accordance with SOLAS Ch. II-1 Reg. 13.2.3 (2014 issue) and IMO MSC/Circ. 736 Paragraph 2.1.
Limited up to and including 110 mm outer diameter. Only piping type approved for use in essential
systems (tested for internal and external pressure) could be used in such application. If the flag
Administration has specific requirements this will prevail.
