ASME SA182 F304 / F304L Tubesheet For Heat Exchanger Tube Bundle
Leave a message
If you are looking for high-quality tube sheets for heat exchanger tube bundles, ASME SA182 F304/F304L stainless steel tube sheets are one of the most reliable options. Made from forged austenitic stainless steel, F304/F304L tube sheets offer excellent corrosion resistance, good weldability, and a long service life under high pressure and high temperature conditions.
Gnee offers precision-machined F304 and F304L tube sheets, all with complete traceability and EN 10204 3.1/3.2 factory certificates-all products are in stock and delivered quickly.
What are the main differences between F304 and F304L tube sheets?
F304L has a lower carbon content (≤0.035%), resulting in better weldability and resistance to intergranular corrosion compared to standard F304.
Are these tube sheets suitable for seawater environments?
F304L performs well in mild seawater environments. However, for long-term marine applications, F316L is recommended.
