Stainless Steel Water Tank ManufacturingLVJIA

SUS 304 is the default for municipal and building water and suits the large majority of orders. SUS 316 adds molybdenum, which resists chloride pitting, so it is the grade to specify for coastal air, softened or chlorinated water and swimming-pool plant. SUS 316L is the low-carbon version and is preferred where a stainless steel water tank is welded in thick section, because it resists sensitisation at the weld. All three are food-grade. Send a water analysis with the enquiry and LVJIA will recommend the grade rather than let the price decide it.

Both are built here. An argon-arc welded stainless steel water tank is a single sealed shell with the smoothest internal surface and no gaskets to maintain, which suits process and food duties. A bolted sectional tank is assembled from pressed panels with sealed joints, which is the only practical option when the tank has to pass through a doorway and be built inside an existing plant room. The wetted material is identical; the choice is about access, maintenance and whether the vessel will ever be moved.

Standard production runs from 150 litres up to 200 m³, with larger sectional tanks built on request. Plate thickness is 1.5 to 4 mm (standard; up to 8 mm by design) and is set by tank height rather than volume, because it is the head that governs the hoop load: thin plate low down on a shallow tank, heavier plate where the water stands deep. A stainless steel water tank can be square, rectangular, horizontal or vertical, so tell us the footprint you have and the volume you need and the arrangement is drawn around them.

A standard stainless steel water tank is rated 0 to 100 °C, which covers chilled buffers, ambient potable storage, fire reserves and domestic hot water. Polyurethane foam insulation with a stainless cladding is offered as an option where heat loss or condensation matters, and the insulation is applied at the factory rather than wrapped on site. For steam, pressurised or cryogenic duties the vessel leaves the water-tank range and is quoted separately against the applicable pressure-vessel code.

Yes. Every stainless steel water tank is built from food-grade SUS 304, 316 or 316L, and the standard internal finish is a 2B mill surface, which is smooth enough to resist biofilm and easy to swab clean. Weld seams are pickled and passivated to restore the chromium oxide layer rather than simply ground flat. Tanks carry CE certification for water tanks under ICR/VC/HS2506113, and each finished tank is filled and held at full head before packing, with 100 per cent of finished product inspected.

Very little is required, which is the point of specifying stainless. Drain and rinse annually, wipe the internal surface with a soft brush and a neutral or mildly chlorinated cleaner, then flush; never use hydrochloric acid or a carbon-steel wire brush, both of which will pit the surface or leave free iron on it. Check the vent screen and the manhole gasket at the same visit. Treated this way a stainless steel water tank comfortably outlasts the plant it was installed with.

Production runs through six controlled stages — enquiry and drawing, plate cutting, forming, welding or punching, inspection and testing, then packing and delivery — in about 15 working days from drawing approval. A sectional stainless steel water tank ships flat-packed on pallets with its bolts, gaskets, ladders and fittings as one kit; a welded tank ships assembled and is crated to its own frame. LVJIA exports to China, the Middle East, Africa, North America and South-East Asia from the plant in Dezhou, Shandong.
