Profile Pipes

Shaped tubes are called such pipes, in which the inner section is different from the round or the outer surface is different from the cylindrical shape. Forms of modern metal shaped tubes, as well as their types, and place of extraordinarily diverse. The reason for this is that these tubes are compared with conventional tubes, a large mechanical strength. Therefore, while keeping them the same strength performance, achieved significant weight loss (25-35%) relative to the circular. More convenient, the assembly of different designs, shape, and the best design, also make use of profile pipes preferable Compared with the traditional. Metallic shaped tubes of rectangular and square cross section, commonly used for manufacturing parts having the shape of plane frames, as well as where required increased time resistance in simple bending, which is very often required in load-bearing structures.

Such use of metal shaped tube of square cross section is justified because it has a moment of resistance to the flat bending is 30 percent higher than equal to her weight round pipe. Application of solid shaped tube as a framework, in the manufacture of shutters on the windows or doors to the garage several times to increase their strength and resistance to mechanical deformations. Of metal shaped tubes collect different floors, trusses, light metal, stairs, handrails, halls, commercial equipment. If a flat curve is attached to only one sides of the metal square tube profile, you can use instead of a square tube of rectangular cross section. This will allow even up to 10% reduction in the total structural weight, while maintaining the same strength characteristics. Depending on where and how to use shaped tubes, dependent and its size. For example, in the automotive industry widely uses square profiles with parties from 25 to 100 mm and the wall thickness from 3 to 8 mm, as well as rectangular, ranging in size from 40x25x3, 100x50x7 mm up. If the pipes are designed to operate at an elevated internal pressure, then increasing the thickness of their walls.

Such thick-walled pipes This applies for example in heat exchangers and reservoirs of steam boilers. In recent years an increasingly clear trend to the use of metal shaped pipes in the building. They are used almost everywhere – in the reinforcement of plastic windows in the construction of supporting structures, and even as an ornamental or decorative items. Almost everywhere where there are higher demands for quality and durability, you can see the metal shaped tubes.

Pressure Washers

The main parameters for selection of pressure washers – is: 1. The purpose of using high-pressure apparatus: – when is briefly using a frequency 6-7 days longer fit pressure washers household, the average duration of which is 120 -150 hours before overhaul. This is an option for personal use, for example, washing your own car. – Average duration of high pressure washers professional is – 4,000 hours. These units are suitable for equipping commercial car washes. – With round the clock continuous work in harsh conditions of use recommended industrial washers pressure. These sinks are also suitable for equipping commercial car washes, which differ in the heavy workload of work during the working day.

This is usually fixed sinks, which can not be moved from place to place. Term services such sinks – tens of thousands of hours. 2. The design of high pressure pump: – piston driven by an oblique washers: a compact, cheap, but quickly wear mechanism. – Piston with a crank-driven: cumbersome, expensive, but . 3. The output pressure: – Domestic: up to 150 bar – professional: Up to 200 bar – Industrial: up to 1 kbar.

4. Type used by the engine: – an electric motor powered by a network – motors Internal combustion engines (diesel or gasoline). 5. Possibility of heating the water. Buying a pressure vessel, in addition, would be appropriate to additionally provide themselves with such items as: – fine filter, which will allow you to work longer assembly – devices for winding high-pressure hose, to prevent possible cases of the inflection hose, which happens quite often. And most importantly, not worth saving when buying High-pressure washers. Buying the cheapest option, you risk a year to spend more than half the original cost of the unit for its repair if the repair will generally be possible. Always try to trim technique according to conditions of your work, suggesting a possible subsequent increase in its volume.

The Designers

It once and for all rooted in our consciousness as a symbol of a dangerous temptation, which entailed a heavy retribution, but the skin as a snake horosha that luxury image prevails over his conscience, and high cost makes it pay off, not thinking about consequences. On a variety of painting and drawing the snake – one of the most amazing fauna, with stunning snakeskin texture, which, of course, making it one of the most desirable and attractive for the fashion industry. The beauty of texture so self-sufficient, that the designers often do not seek to supplement its decorating delights, offering very simple to shape and decoration items and accessories. The selected accessory from python and snakes, will accentuate your individuality, because the snake skin patterns – unique as human fingerprints. You will not find in nature two pythons or other snakes with the same pattern. For the whole python skin is characterized by rounded, diamond-shaped scales, which are longitudinal and diagonal rows, and usually slightly overlapping scales anterior to posterior. In some species of snake scales may have a hexagonal and triangular shape and placed the water plane without overlap (this applies to sea snakes) snake skin is very flexible and resistant to tearing, it is no wonder due to elasticity of skin integument, snakes can swallow prey 2-3 times thicker than their own. The fact that the strength of this amazing skin, but extend the life of the enhancement is also interesting that with age, a product of the snake skin becomes more beautiful: it softens, no abrasion, or rather forming a loop product.

Diving In Hurghada

Diving in the Red Sea an ideal spot for diving, without a doubt the Red Sea. Always warm weather and clear water, no industry, which would spoil the ecology of this amazing place, thousands of species of fish, one more beautiful than the other, varied, never repeated, the color and shape of the coral reefs. All these conditions have made the Red Sea for thousands of attractive, if not millions of travelers. and Most of them seek to plunge into another reality. A sea water, in general, it's really another reality. There is no noise and uproar, the silence here, and my head starts to work differently, and your whole body completely differently respond to "hover" in this very different world. Diving in Hurghada, Hurghada And, without doubt, the most wonderful place for diving in the Red Sea.

It can dive all who wants it – from nothing greenhorns able to tough guys who have committed more than one dive in different places. In the vicinity of Hurghada over forty dive sites, and probably more so Hurghada is so popular. Virtually Each hotel has its own dive centers that teach beginners and turn them into expert divers, with the presentation of special certificates. If you just want to try – what it is – diving, then this will help you experienced instructor, who will be always with you. Options for scuba diving of different levels and duration of great variety – just choose. I would like to emphasize that instructors in many Diving centers have Russian boys, so communication problems will not arise.

Efficiency Corrosion

Corrosion of metal brings big problems in the manufacture and operation of metal. Specialists are always looking for ways to protect the materials from this scourge. The fact that the metal active contact with the environment, engaging in a variety of electrochemical or chemical reactions. The result of such processes is the oxidation and destruction of material. Experts demonstrate disappointing facts.

By The research carried out corrosion causing huge damage to industry, which amounts to 4% of gross national product of each state. Loss of metal as high as 20% per year. Corrosion – a natural process. It can not be avoided, but can only slow it. In the atmosphere, there are plenty of substances such as oxygen and water.

Acting on the metal, they cause its oxidation. The entry of the material in reaction is its oxidation. On the metal is often possible to observe rust. That she is a demonstration of the chemical processes occurring. This means that corrodes steel structure that is destroyed. For Surface protection designs use special coatings. One of the most economical, efficient and reliable way to conduct anti-corrosive treatment of the product is galvanizing. This procedure applies to protect a wide variety of metal products. First of all, zinc are: mast antennas, telegraph wires, wire ropes, sheet metal, plumbing, fasteners machinery and instruments, pipelines. An equally important step is the pre-processing of products. Galvanising is produced in factory conditions, a way of galvanizing or thermal diffusion method. Design finds special thin coating, resistant to corrosion. Zinc layer significantly prolongs life and improves the reliability of the product and its parts. In practice, it is proved that the metal is not protected from corrosion, are ten times less than secure. Demand for galvanizing continues to grow.

Lamination Films

Lamination as a way to protect paper and other materials used in various spheres of activity. Therefore, the varieties of lamination film set. And every type of films – especially his use. Widest range of materials for lamination can solve any problems for the protection of documents and production of decorative and promotional products. The first difference laminating films from each other – it is their a variety of thickness. The thickness of films for lamination ranges from 8 to 250 microns.

In the first case we are talking about a very thin material printing purposes. In the second – on a massive dense film, which can be seen to calendars, pins, decals and driver's license. Thin films are mostly used for laminating the lottery products, and therefore are supplied in rolls of 100 to 3000 meters in length and from 305 to 2000 mm in width. Since laminators are "package" that are commonly used in offices, and industrial type roll laminators, laminating film, and then they are packaged and rolled. Film for a batch of laminators is a double package of film, bonded to one side. Laminiruemy document is embedded between two layers of film.

Lamination Films differ primarily by: Format Thickness of the film itself. Several surface texture tips for proper selection: Choosing the purchase of film format, you need to consider the size of documents, photographs, badges, etc., that you intend to laminate. No need to buy, such as film A4 if you laminate the photos, size 9×12 mm, too many films have just cut. Quite simply, if the size of what you'll laminate coincides with one of the standard size of the film for lamination. If not – you need to choose a slightly larger size of the film. If you laminate the sheets just so that they do not get dirty and are not damaged by moisture, you have enough film thickness of 60 or 80 microns. Laminated sheet with the be sufficiently thin and easily , but protected from moisture, dust, etc. Thicker film for lamination also protects against mechanical damage as well as provide laminated documents with a certain toughness. For example, lamination passes more likely to use the film thickness of 150 microns. Most suspension film thickness for batch laminators – 100-125 microns. Produced the same film for lamination in sizes from 54 x 86 mm to 303x426mm and the thickness from 60 to 250 um. Surface texture of the film are very important for the perception of the observer. For example, the glossy film is able to make the colors more vivid and bright, while the matte film can reduce the contrast to create a softer and relaxing experience. The latest versions of films to laminators enable you to add prominence to the surface of the image and the different textures of finishes – such as the crystal pyramid, "goose bumps", textile yarn (flax), frosty pattern stochastic moire and even holographic effects. These textural finish in appearance are somewhere between gloss and matt surfaces. With their thin, almost imperceptible structure, they also reduce the visibility of the scratches are noticeable, for example, on a clean glossy or matte finish. The most widely used batch glossy film for lamination of various formats. Rarely used matt Honed or textured film.
