OGRAX-KSK-A fire protection system (OGRAX-T + OGRAX-MSK)
Weather-resistant two-layer fire protection for steel, R90–R120: OGRAX-T thermal fire-insulating layer and OGRAX-MSK intumescent paint.

OGRAX-PM collars have been on the market since 2003. Each is a red split steel housing with an intumescent insert that expands by at least 2000% when heated from +180 °C. The collars are fitted both to pipes being laid and to existing sewer and water supply pipes, with the lugs secured by anchor bolts. The fire resistance of the penetration is EI 180, the operating range is from −50 to +60 °C, and the service life is at least 25 years. Sizes: 16, 25, 32, 40, 50 and 110.
