DQS protects steel pipes and above-ground pipelines on pipe racks, in plant buildings and in equipment piping across Uzbekistan against corrosion: we paint new lines and repair the coating on old ones. Hot and operating lines are painted without shutdown. We do not take on underground sections or soil-to-air transitions.<\/p>\n<h2>Weak points of a pipeline<\/h2>\n<ul>\n<li><strong>Supports and clamps:<\/strong> as the pipe moves with temperature, it rubs the coating off against the support, water is trapped in the gap, and none of this is visible from the side.<\/li>\n<li><strong>Weld joints:<\/strong> on new lines they are left bare until testing \u2014 if they are not painted afterwards, rust will start there.<\/li>\n<li><strong>Flanges, bolts, valves:<\/strong> paint goes on thin on edges and in crevices.<\/li>\n<li><strong>Underside of the pipe:<\/strong> water runs down here, and on a pipe rack it is the hardest part to reach.<\/li>\n<li><strong>Under thermal insulation:<\/strong> moisture gets in through damaged cladding, and the steel rusts unnoticed.<\/li>\n<\/ul>\n<h2>Why a pipeline is harder than a frame<\/h2>\n<p>Pipes run in tiers, several lines side by side, above roadways and equipment. We work from lifts, and where machinery cannot get through, certified industrial rope-access technicians go up.<\/p>\n<ul>\n<li>Before abrasive blasting we wash off oil and product and cover instruments and valves. Where blasting is prohibited, we clean by hand, as agreed with the client.<\/li>\n<li>The side of the pipe facing the neighbouring one, welds and edges are painted by brush: spraying leaves a thinner film there.<\/li>\n<li>We compare the pipe wall temperature, not the air temperature, with the dew point: a cold pipe \u201csweats\u201d even in hot weather, and we never paint over condensation.<\/li>\n<li>We measure dry film thickness with DeFelsko PosiTector 6000 gauges around the entire circumference of the pipe, including the underside and joints. The results go into a report that stays with the client.<\/li>\n<\/ul>\n<h2>New line or repair<\/h2>\n<p><strong>New pipes<\/strong> are best cleaned and primed before installation, with the joints and sling-damaged spots touched up after assembly and testing.<\/p>\n<p><strong>Repair<\/strong> starts with a walk along the route: we mark where the coating holds and where it has flaked or rust has crept under the film \u2014 and propose spot repair or repainting of the section. We feather the edges of the remaining coating and select a material compatible with the old one.<\/p>\n<p>The coating system is set by the design; without a design we select it for the medium and the line temperature. We use paint systems based on abrasion-resistant epoxy coatings.<\/p>\n<h2>How many m\u00b2 are in a pipeline<\/h2>\n<p>The area is calculated from the outer surface: 3.14 \u00d7 outside diameter \u00d7 length. For example, one kilometre of \u00d8219 mm pipe is about 690 m\u00b2, and that volume already qualifies for the offer: <strong>15% off<\/strong> on orders from 500 m\u00b2. We will apply a trial area on your pipeline free of charge before the contract is signed. We give a warranty of up to 10 years on our work.<\/p>\n<h2>From our projects<\/h2>\n<p>Painting of pipes and pipeline assemblies \u2014 bends, tees, flanged pipes \u2014 and dry film thickness
