Profile Pipes

| March 31, 2012

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.

Diving In Hurghada

| March 22, 2012

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.

Lamination Films

| March 11, 2012

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.
