Anti-corrosion protection of storage tanks and vessels<\/span><\/span><\/h1><\/header>
<\/div>

You cannot judge a tank by its shell: it may look fine while the steel at the bottom, on the roof and inside is already deteriorating. So we start the inspection with the bottom edge, the lower-course welds and the roof, and plan the protection zone by zone. DQS provides anti-corrosion protection of vertical steel tanks and steel vessels across Uzbekistan with its own crews.<\/p>\n

Protecting a tank zone by zone<\/h2>\n

Bottom edge and shell-to-bottom weld<\/h3>\n

Water runs down the shell and stands on the projecting edge of the bottom (the annular plate) at the shell-to-bottom weld (the chime), with dirt collecting next to it \u2014 rust appears here earlier than higher up the shell. The underside of the bottom is inaccessible after assembly, so on a new tank it is protected before erection.<\/p>\n

Lower courses, welds, supports<\/h3>\n

The lower courses suffer from splashes and damp at the base; on horizontal vessels moisture is trapped between the shell and the saddles. On weld beads, edges, nozzles and ladder supports the paint film comes out thinner, so welds and details are stripe-coated separately before the main coat.<\/p>\n

Shell<\/h3>\n

We blast and prime the shell section by section so that clean steel has no time to flash-rust. In the morning there is dew on the shaded side, while the sunny side overheats during the day, so we check the dew point and steel temperature on each side. The topcoat is UV-resistant; we take the system and thicknesses from the design or select them for the conditions: dust, fumes from neighbouring plants, product heating.<\/p>\n

Roof<\/h3>\n

Water stands in the sags of the roof plating, and from inside the roof is eaten away by condensate from the vapour space. We inspect weakened plating first: deep pits and through-corrosion are repaired before painting \u2014 a coating will not bring back lost steel.<\/p>\n

Inside<\/h3>\n

The fastest to deteriorate are the bottom under the water layer and the band where the product level fluctuates. We provide internal protection for any medium and select the coating for the stored product:<\/p>\n
