In certain parts of England the treated potable water is stored in underground reservoirs prior to being distributed to homes and businesses. These underground tanks are typically constructed of concrete or brick/block with a concrete reinforced roof. The land above these reservoirs is used for purposes such as farming which includes the use of fertilizers and chemicals. Constructed 30 to 40 years ago, the concrete roofs of the reservoirs have become porous potentially allowing dirty rain water and farming chemicals to penetrate the concrete and enter the drinking water. The customer was looking for an effective long term solution of sealing the reservoirs that did not require rebuilding or taking them out of service.
King’s Daughters Medical Center in Kentucky had problems with the safety and sanitation of their shower stalls. The showers were tiled, a slip hazard in this wet environment. The grout was unsanitary, holding onto moisture and creating an environment where mold, bacteria and other germs could grow. The tile was easily damaged from hospital equipment. Once damaged, moisture seeped behind the tile causing the drywall to deteriorate allowing mold and bacteria to grow in the wall. The hospital required a solution for the shower stalls that would provide: 1) A seamless floor-wall-ceiling membrane. 2) A slip resistant surface texture on the floors. 3) A smooth and easily cleanable walls and environment that would inhibit fungus and bacteria growth a durable. 4) A long lasting solution an aesthetically pleasing, uniform, and with color.
CP Kelco is a global producer of hydrocolloids. At the facility in Denmark they needed the floor of 2 sewage water tanks 450 m2 each to be re-coated. The facility could not live with a long shutdown time because of a 50 % reduction of production in the factory.
Sewage purifying tanks, like these from the Emek Hefer Region of Israel, are designed to purify waste water from the surrounding town. Waste water contains many harsh substances that slowly ingress into the walls and floor of the tank, degrading the metal and causing the sewage to leak and contaminate the groundwater. A solution was needed to provide a watertight barrier that could prevent the numerous chemicals and acids from seeping into ground water. The chosen application would have to offer a very quick turn-around to allow the water purification system to return to service with minimal disruption.
The world’s largest company in the field of sea water desalination (SWCC) consulted LINE-X to find a solution to protect the company’s brine drain channels. Each desalination plant consists of several production units. Each unit has a drain channel that allows the return of brine to the sea water. The brine has a very high salt concentration and is delivered at a high temperature 50-80 C to the sea through concrete channels.Over time the concrete channels suffered great structural damage. Salt water penetrated through the concrete to the structural steel leading to corrosion and failure. The channel walls were critically damaged and falling apart in several areas.
In the railroad industry cross ties are often made from timber. However for traffic and heavily used areas such as turnouts and switch yards, they can be made from steel which generates several advantages to the railroad. Steel ties are stronger than timber, this allows for wider tie spacing. It also reduces material costs in building the rail bed. Steel rail ties also maintain the track gauge. Allowing for the railroad curves to be smoother and safer. The challenge of steel cross ties keeping them stable in the gravel ballast. The smooth hard steel does not allow the gravel to “bite,” or maintain proper alignment. This can lead to increased maintenance cost.
Power Transmission Towers often rust and corrode over time, and without proper maintenance, utilities may need to invest in untimely and costly replacement. Because towers are sometimes located close to major roads, it is important to the surrounding community that these structures are properly maintained. In the past residents have complained of the visual appearance of the towers. As a result, this customer needed a protective coating that is aesthetically pleasing while it also protects the towers from rust and corrosion.
Petrol station pump islands made of steel bezel and concrete often fail due to continuous use. Diesel and gasoline spills rust and corrode the metal bezel, and car tires wear down the concrete islands over time. As a result, the company had to fix and paint the islands every six to twelve months. That was a problem for the company, because even between re-coating, the islands were looking worst for wear.
Extreme weather can wreak havoc on valuable outdoor equipment. Rust and corrosion will inevitably damage metal exposed to harsh conditions. Steel enclosures like those found at the Tanajib compound, ARAMCO, Saudi Arabia, had pronounced rusting due to the presence of high humidity, salt and heat in the coastal area.This environment caused the existing paint to crack and peel with corrosion present in several spots. If left untreated, underlying rust or corrosion could result in immature failure of the equipment or enclosure.Notably, the rooftops of these enclosures showed a higher corrosion rate than the rest of the structure Moisture accumulating on the roof, combined with direct UV rays and presence of salt, accelerated the corrosion.The aim of this application is to control corrosion and prolong the equipment lifespan under harsh weather conditions present in the region.
On the oil rig SOUTH ARNE in the Danish North sea, they were experiencing a constant loss of fluids in their Clean in Place (CIP) tank. The fiberglass tank didn’t have the right structural support, resulting in cracks in the joints of walls and floor. The operators needed and cost effective solution which would not only provide the structural support needed, but must minimize downtime.
