M12 carbon steel corrugated gasket can withstand high temperatures up to 300℃ (for boiler pipeline sealing)

High-Temperature Warriors for Boiler Pipeline Sealing Designed for boiler pipeline sealing, M12 carbon steel corrugated gaskets thrive in 300℃ high-heat. Made of 0.20-0.30% carbon content steel, heat-treated to HB 180-220, they ensure thermal stability in fluctuating temps. Precise Specifications for Reliable Sealing Meeting GB/T 19066.3 and ASME B16.20, these 12mm gaskets with 0.8mm wave height and 3mm spacing grip flanges tightly. Their 5% elasticity handles 16MPa pressure and thermal expansion. Tailored for Boiler Pipeline Environments Ideal for water walls, superheaters, and steam headers, their corrugated shape boosts sealing area by 30%. Resistant to oxidation in dry steam, they last over 8,000 hours under rated use. Why Choose Carbon Steel Corrugated Gaskets? Superior to rubber (degrades above 150℃) and low-alloy steel (brittle at 300℃), they absorb 0.3mm misalignment. Costing 25% of Inconel gaskets while delivering 60% of the performance, they're a smart industrial choice.
