Most customers believe glass to be quite a fragile material. More and more customers are nonetheless coming to us, intending to decorate their staircases in such an edgy and virtually zephyrian style. The point is that a glass stairway may look zephyrian and weightless, giving a feeling of suspension over the ground. But in reality glass stairs are quite strong, reliable and durable, just like a regular rock, and are capable of withstanding high loads. In our applications we use high-strength glass that has been subjected at least to thermal treatment or at most glued together into a safety glass (triplex). We can fabricate any or all structural components of stairways and railings from glass: stairways, railings, stairs, hand rails, and bars. Moreover, you can order from Karvan-Glass the self-sustaining glass balcony parapets that will give you maximum observation field from your sunroom or balcony.
Due to its special thermal treatment, tempered glass boasts higher impact strength and freeze-thaw resistance compared to regular glass. All tempered glasses are subject to mandatory edge pre-treatment. If broken, such glass falls apart to small fragments with uncut edges. The glass tempering has the following effects:: impact strength rises 5-10 fold flexing strength rises 2-3 fold operating temperature range increases to -150 to +300°C The tempered glass has quite a broad range of applications: glass panes, multilayer glasses with different properties, all-glass partitions, staircases, stairs, hand rails, car windows etc. The tempered glass can withstand hard blows perpendicular to its plane. Despite its improved properties, however, tempered glass is still a fragile material. It is especially susceptible to end loads, so such glass should be installed with extreme care.

It has been decades that architectural glass sheets have been utilized as a construction material. Over this time, manufacturers have achieved a significant success in terms of fabrication and finishing technology, bringing the glass properties almost to perfection. Increasingly pronounced in glass industry is the nanotechnology sector, which renders it specific and extraordinary properties in terms of operation and aesthetics, thus opening new bright perspectives for architects and designers. It would be fair to say that it was new safe multilayer glass items that helped discover most significant improvements of properties and capabilities of glass as a construction material. All valuable operation and technical properties of such glass are achieved by using a “sandwich” principle, i.e. by creating a multilayer composite structure with a polymer layer in between. It is still difficult to appreciate the whole significance and implications of this development. Regrettably, many issues of perfecting the technology and equipment that helps create multilayer glass (triplex production equipment) have been outside researchers’ focus of attention, thus hindering the practical development across the entire range of safety glass application. Most new properties are still unknown and require serious theoretical and experimental developments to uncover. Among these: detailed study of formation and development of multilayer glass production technology based on innovative polymer materials with a higher strength compared to existing materials, research of properties and application of hybrid structures based on new composite elements. The combination of fragile glass and plastic materials (for instance: polycarbonate and glass sandwich panels, glass and acryl tile etc.) enables to optimize the functionality of multi-layer shutterproof glass. It is beyond doubt that ongoing researches in this area will boost the improvement of existing and development of new approaches to designing and creating multilayer glass machines for industrial-scale production.
Increase of ecological requirements to emissions of car engines and toughening of operation terms of modern combustion engines require usage of various additives to petrols in larger scales. Restrictions on sulfur content until 0,001 and 0,005% were set forth in Sweden for the 1st time in 1991, and until present they are the strictest one. In 1993 the restriction of sulfur in fuel till 0,05 was applied in USA, in 1994 – in Canada, in 1997 – in Japan. Since 2000 diesel fuel with sulfur content no more than 0,035% is applied. Supposedly, since 2005 sulfur content in fuel wont exceed 0,005%. Along with decrease of harmful emission in exit gases, application of ecologically pure diesel fuels entailed a number of problems: breakdown of fuel pumps, due to decrease of lubricating ability of diesel fuels and .increase of corrosion activity, related with removal of surfaceactive substances able to form protective film. In 2005-2010 stiffer norms on sulfur content are proposed: up to 10 ppm and polycyclic aromatic carbohydrates up to 2%. Starting from 2000, the indicator of lubricating properties of diesel fuels under ISO 12156-1 at HFRR device is included in European standard regarding the diesel fuel EN 590, basing on it the norm is set forth: diameter of wear scar is no more 460 mkm. Requirements to quality of diesel fuels under EN 590

Naphthenic acids and their derivatives are widely used in more than 40 sectors of national economy. Naphthenic acids in a form of lead, manganese, zinc, ferrum, aluminium, chrome salts and in a form of other derivatives, are used in preparation of paint driers, varnishes, paints. Free naphthenic acids are used as a part of inks and improves their mobility. These acids are also used as thinner for aniline colorants, sleeper impregnation material preserving wood from rotting. Both free and derivative naphthenic acids have effective fungicidal, insecticidal, bactericidal and preservative parameters which are used in weed and pest control, for impregnation of wood, sail fabric, canvas, rope, tarpaulin, fishing gear and other materials regularly affected by moisture, bacteria, pest, etc. Lead, chrome, cobalt and manganese salts of naphthenic acids are used as antistatic, antideteriorant and antifoam additives for fuel, jet engine fuels and oils. Lubricating and emulsifying materials used for cooling of shearing machines, pasting, lubrication grease for high-pressure plants, demulsifiers brea-king petroleum and oily emulsions are based on naphthenic acids. Simple and compound ethers of naphthenic acids are used as plasticizers for production of polymeric materials, general rubber goods, polyvinylchloride plastic, hydraulic liquids, etc. Naphthenic acids are successfully used even at cleaning of rareearth elements, extragens of radioactive materials, catalysts, oxidation and oxonation processes, agricultural growthregulating substances, drying accelerators for glassreinforced polyesters, etc. In order to meet consumer needs for naphthenic acids, “KARVAN-L” company has developed technology and established commercial installations for output of high-purity acids.
Petroleum refining is characterized by the largest amount of systems exposed to corrosion compared to any other sector of the oil industry. Corrosion problems occur everywhere, from the points of raw materials delivery up to removal and transportation of the refined products. Corrosion control measures shall be taken at crude oil distillation plants and units for alkali treatment of oil, gas plants, reformer and cracking units, straight run deisobutanizers, units for adsorption of hydrogen sulphide from aqueous solutions, furfural treatment units etc. Liquid composition may vary depending on a particular stage of the oil refining cycle – from sulphurous, acid oil-water mixtures fed to refineries to final products (e.g., gasoline) with negligible water content. It is hardly possible to use any “universal” corrosion inhibitor due to the variety of process mechanisms that may cause intense corrosion of equipment used in the oil sector. The need to ensure property package determining processability and compatibility of the inhibitor with corrosion medium components necessitates development of an inhibitor that would be functional in different corrosive conditions. Oilfield water containing large amounts of chloride ions, oxygen, carbon dioxide and hydrogen causes and promotes further development of local electrochemical processes, which represent the most dangerous type of corrosion and failure of metal. Oilfield practice shows that the most dangerous local corrosion damages also occur in the presence of microorganisms. In order to protect oil equipment against chemical and bacterial corrosion, Karvan-L company designed efficient and cost-effective water-soluble and oil-soluble corrosion inhibitors. Corrosion inhibitors are nitrogen-containing surfactants, produced based on natural acids with addition of film-forming admixtures and biocides.
It often happens that people confuse glass panes and vinyl windows. These are not synonyms, however. A glass pane is a part and nearly crucial part of a window structure. This is a translucent structure consisting of two or more glasses that are fixed (glued) together along the outline using spacing bars and sealant compounds. Main functions of a glass pane: natural lighting, thermal and noise insulation. Glass panes are categorized by manufacturing process: standard, where molecular sieve is poured into a metal or vinyl spacer, after which the glued glass sheets are plastered along the edge with silicon, isomelt, polysulfide or polyurethane sealant compound, thus providing the secondary sealing. Warm edge technology-based manufacture This is a new and promising technology. It differs from the standard technology in that instead of several production steps as in the case with glass pane it involves only two (flexible spacer application, pressing), thus greatly saving time and cost. Such glass pane is warmer than that manufactured using a standard technology. As defined in GOST 24866, glass pane are categorized as follows: by number of chambers. A space between each two glass sheets is called a chamber. Glass panes can be single-chamber (two glass sheets), double-chamber (three glass sheets) and so on. by width The glass pane width is the full width considering its glass and air part. Glass panes can be 14, 16, 18, 20, 22, 24, 28, 32, 36, 40, 42, 44 etc. mm By glass type: regular energy-efficient glass with low-emission coating (hard or soft, also known as - or I-type) noise-resistant triplex sun-screening tinted or film-coated glass shutterproof glass with a high protection class.
