European Valves

Traditionally, for such pipelines as the shut-off valves used in steel or cast-iron gate (malleable and ductile cast iron). However, the restrictions regulations apply to the use of fittings made of cast iron, so the main type of valves used in heat and power facilities, is a steel armature. Steel Ball valves with flanged or weld, which appeared on Ukrainian market in the last decade and performance which were highly appreciated by experts, are gradually replacing conventional valves. Idt energy does not necessarily agree. What are these ball valves? The main elements of ball valves are: housing, the locking element in the form of a sphere with a cylindrical bore, the spindle, through which rotation of the ball, removable handle, seals, spindle and ball. Housing ball valves made of carbon steel is welded, which has no movable joints that require tightening. Additional information is available at idt energy. Housed in a building polished ball is made of stainless steel. On both sides of the ball adjacent to the sealing of carbon – teflon gaskets, resistant to abrasion and impacts of pollution. Disc springs pressed seal to the floating ball and ensure reliable operation of the ball valve in the low and high temperatures.

At the top of the crane is located spindle with sealing gaskets. Through elastic connection of the ball and spindle under the influence of operating pressure ball moves freely in the direction of the seal. All ball valves have a good performance and are in demand construction companies specializing in the installation of heating and water systems, and other industries. However, according to experts who conducted a comparative study of quality and price characteristics various steel ball valves and other shut-off control valves, they have several advantages: – a thickening of the wall (special version for Eastern Europe) that increase the strength of the ball Crane – elongated spindle that allows for isolation of the crane – high reliability due to the fact that all ball valves are full test cycle, guaranteeing a high level of quality in accordance with European standards – lower price in comparison with valves and dampers. Ball valves – a reliable and durable form of valves, which is better adapted to other Ukrainian thermal networks and have the lowest price with high quality. With this in mind they are the most promising for the Ukrainian market and CIS countries.

Thermo HSP

The choice is yours! Self-leveling floor – it's non-shrinking blend with a complex chemical mixtures and granules on the basis of sand and cement with the addition of superplasticizers, high wear-resistant device for floor screeds as a base layer in the garage, as well as for leveling horizontal surfaces under any cover. Most often, self-leveling floors are used as fine concrete foundations for the device, castings, etc. Self-leveling floor can be used both in production internal and external works. you need to pay attention to the preparation of the surface to be dry, firm, free of paint. If you complete all the items on the application, the floor will last you 6 months, as this term This structure maintains its quality. The advantages of such self-leveling floors, you can show a long time: it is easy to clean, the use of any buildings, different colors, self-leveling, easily repairable and more more. order the self-leveling floors and you can save on a lot.

Self-leveling floor Ursa URSA offers popular products for all segments of thermal insulation and soundproofing. Whether it's designing buildings, Civil repair or technical insulation, pipes, facades, roofs, walls or floors, the question always arises, who to go for materials for a consultation. That's where you need to know about the products of glass staple fiber and extruded polystyrene firm URSA, which are needed for construction. On the cement is our home. Cement is not a single species, many of them: this is Portland cement, portland slag cement, hydrophobic, fast-curing, pozzolan, expanding, plasticized, alumina, sulfate, straining, oil-well, white cement. Each type of the properties that are needed in certain construction projects. Cement is indispensable, and each year it improves. Time stands still and if a few years, decades ago, there was only one type of cement, which were all at home, is being developed by many species, and the buyer is entitled to order the one that he 'taste', more or less quality or less quality.

A professional can not offer only one type of cement, and, it is recommended to give the customer a choice. There many waterproofing slabs, each of which has its own structure, its basis orientation. For example Thermo HSP is based on the fiberglass, which is covered with a film that insulates certain materials with construction, which is very necessary thing. Developed and rolled waterproofing material for roofing and waterproofing is also based on the glass, whose surface is covered with foil. Plastering – very complicated process that depends on many other processes. Plastering – the removal of the irregularities of construction, finishing, as well as giving them the desired shape and desired texture. Find out detailed opinions from leaders such as Dr. Mark Hyman by clicking through. It is in these situations, acts plaster – coat of special products. Stucco is primarily used inside buildings. Plaster has properties such as high water vapor permeability, water-repellent svoystvomi, weather and many other qualities that may have only quality plaster. But we must not forget that the quality of plaster depends on the developed surface on which it is imposed, the humidity, the type of application, from professional who performs the work. So the choice of high quality plaster and do not forget about the importance of the choice of the worker. After all, once underpaid, you have to start it again, because the plaster is characteristic rot and fall off, that not everyone will like – it's huge financial losses. Make a quality choice!

Marine Fuels

Distillate marine fuel consisting of lighter fractions obtained by distillation installations for oil refining, are characterized by low viscosity, v = 3 h-6 mm2 / s, so do not require heating before serving to engines or boilers. Heavy Marine Fuels are a mixture consisting of the residual products of petroleum and distillates. Depending on the balance of light and heavy components viscosity of heavy marine fuels, as well as their other indicators, varies considerably. In Russia, the quality of marine fuels are regulated by state standards and specifications. Abroad, the quality of marine fuels specifications determined supplier firms of British (BS 2869: 1967) and American (A5> TM-D975 and D396-67). Began in the 70s and more distributed process involving the production of ship fuel oil products recycling demanded revision existing standards and specifications, the expansion of the limit values of quality and attraction of additional indicators (such as the aluminum content, stability and compatibility of fuels, etc.). Distillate marine fuel Due to limited resources and high value distillates, diesel marine fuel – referring to the class of spirits, in the USSR, approximately 1.7 times the cost of heavy marine fuels.

Consumption of marine diesel fuel to Navy ships is only 6-12% of the total amount of fuel burned. Its mainly used to support medium-and high-speed diesel engines, that either by design or because of unsuitability of toplivopodgotovki (no heat) can not be translated into a more severe marine fuel. In the main engines of ships ship diesel fuel used exclusively during the maneuvers, and for flushing the fuel system before stopping. The domestic industry produces marine diesel fuel in accordance with GOST 305-82 by mixing fractions of direct distillation of sulfur crudes, hydrotreating and dewaxing the past, with a catalytic gas oil. The presence of a catalytic gas oil, reduces the operational properties of fuels, in particular increasing its propensity for deposition. Marine fuel produced four grades: A, 3, AP, A, which is on the sulfur content is divided into two subgroups: with S%, with S == 0,21 – 0,5%.

The content of mercaptan sulfur in the sulfur of both subgroups is limited to 0.01%. As replacement marine diesel fuel in ships of sea and river vessels are widely used gas turbine fuel (GOST 10433-75). Fuel is obtained as a byproduct in the process of delayed coking unit in the development of petroleum coke, metallurgical industry required. Gas turbine fuel and TG TGVK have a higher density and viscosity, but not so high that they had to warm up before use. For these fuels have a higher sulfur content (1 and 2.5% respectively), and what should be paid attention to particular, they contain up to 25% tar. This leads to their low stability, manifests itself when heated and mixed with other fuels. Since 1988, the oil industry began to supply the navy ship's low-viscosity oil designed to replace diesel and gas turbine fuels. It produce fuel by mixing the distillate of secondary processes (coking, thermal and catalytic cracking) of diesel fractions with a high end boiling point, taken from the atmospheric and vacuum columns. On Compared with the ship's diesel fuel to it less stringent requirements (may be twice as high viscosity, 11 mm2 / s, the sulfur content to 1.5%, lower TSCH – not less than 40).
