30000L Stainless Steel Pressure Vessel Water Tank 304/316L Horizontal/Vertical CE

30000L Stainless Steel Pressure Vessel Water Tank

We fabricate this 30,000-liter tank in both horizontal and vertical orientations, depending on your site layout and process flow. The shell is rolled from 304 or 316L stainless steel plate—your call based on the stored media. For potable water or general storage, 304 is sufficient. For chlorides, acidic washdowns, or pharmaceutical-grade service, we push you toward 316L. We\’ve seen too many tanks fail because someone saved a few dollars on material and then paid for it in pitting.

Every weld is full-penetration TIG on the root, with MIG or stick on the cover pass for thicker plates. We grind the internal welds flush and passivate the surface. If you need a mirror polish for hygienic applications, we go to 180-grit or finer, with a final electropolish option. The top manhole is a standard 500mm opening, hinged and clamped, with a silicone or EPDM gasket rated for your pressure. This tank is designed as a pressure vessel, so the heads are dished (either elliptical or torispherical) to handle internal pressure up to 3 bar, vacuum service, or a combination—but we always confirm the actual rating before we cut steel.

We\’ve built these for breweries, dairy plants, water treatment facilities, and chemical processors. The key is matching the tank to the duty. You need to tell us the specific gravity of the liquid, the operating temperature, whether you\’ll use CIP spray balls, and if there\’s any agitation or heating jacket. We fit nozzles for level transmitters, temperature probes, overflow, drain—wherever you need them. The standard package includes a flat bottom with a sloped outlet for complete drainage, adjustable legs, and a pressure relief valve.

CE certification covers the pressure equipment directive, but we also build to ASME if your market requires it. Customization is routine: different capacities, extra manways, sight glasses, insulation cladding, or internal coils. We\’ve shipped tanks in one piece for road transport and knocked-down for container loading when the diameter is too large. Let us know your dimensions and access constraints.

FAQ

How do I choose between 304 and 316L? If your liquid contains chlorides (salt, bleach, some acids) or you\’re in a coastal environment, go 316L. For neutral water and mild chemicals, 304 is fine. We can review your MSDS and recommend.

Can this tank handle vacuum? Yes, but the design changes—thicker shell and stiffening rings. We need the max vacuum rating and whether it\’s full or partial.

What about cleaning? We can add CIP spray balls, a sloped bottom, and a tangential inlet to minimize residue. Tell us your cleaning cycle.

Do you provide drawings before fabrication? Yes, we send a GA drawing and nozzle schedule for your approval. We don\’t cut steel until you sign off.

What\’s the lead time? Typically 4–6 weeks after drawing approval, depending on material availability.
