Copper Pipe Pulled

Posted by Sylia on

Lack – much greater complexity and fragility of the installation of pipelines. Cast iron pipes are made of gray iron castings in a stationary sand molds, as well as centrifugal and semi-continuous casting. The strength of cast iron pipes depends on the thickness of their walls, as well as the method of casting. Pipes manufactured by centrifugal casting and semi-continuous, stronger pipes made by casting in sand molds. To prevent corrosion of iron pipes from their outside and inside covers petroleum bitumen.

As a result, the inner surface of the pipe becomes more smooth, which reduces the friction of water against the pipe wall. Cast iron pipes are divided into pressure (water) and sewer. Water pipes made of nonferrous metals. Copper tubes are round, made of copper marks M1, M2 and M3. Copper Pipe Pulled produce cold rolled and outer diameters of 3 to 360 mm, wall thickness from 0.5 to 10 mm, Pressed – diameter from 30 to 280 mm, wall thickness from 5 to 30 mm. The outer and inner surface of the copper pipe must be free of cracks, cavities, bundles of metal. On the outer surface shall longitudinal risk, small dents, discoloration, the curvature of 5 mm to 1 m for the elongated tube and 15 mm at 1 m for extruded.

Drawn, cold-hard and semi-tube after annealing should try to flattening in the cold state (three pipe from the party). Brass pipes are made of brass brands: L63 and L68 – and cold-drawn tubes and L60, LS59-1 – extruded. Drawn and cold-rolled tubes for special purposes, intended for heat exchangers apparatus, made of brass brands LO70-1, LA77-2 LM68-0, 06. Brass and cold drawn tubes for general purpose release outside diameter of 3 mm to 10 mm, wall thickness from 0.5 to 10 mm, and pressed – with outside diameters from 21 to 195 mm, wall thickness of 1.5 to 42 mm. Along the length of such pipes are dimensional and random length from 1 to 6m. Drawn and cold rolled brass tubes produce a maximum length of 10 m and outer diameter of 10 mm and wall thickness of 1.5 mm. Quality requirements for outer and inner surfaces of pipes and brass to their curvature, the same as that for copper pipes. Pipes made of aluminum and aluminum alloys are produced by cold rolling (rolled) and cold-pulling (pull) and compression. Pipes of aluminum and aluminum alloys produced round, rectangular, square and oval. In recent years become widely drawn and rolled to get the tube shaped profile. The curvature of the pipe wall thickness up to 5 mm inclusive in diameter and 120 mm should not exceed 1 m in length, 1 … 3 mm. On the surface of the pipes allowed longitudinal risks of not more than two 10 mm perimeter depth of not more than 0.04 mm. The pipe ends must be cut evenly and not be free of burrs. Polymer (plastic) pipes of water supply. Plastic pipes are distinguished strength and elasticity, high corrosion resistance, light weight, low thermal conductivity, smooth inner surface. Hydraulic resistance of fluids in plastic pipes less than metal, so their capacity is 20-25% higher. In addition, due to the production of long plastic pipes is reduced number of joints in the pipes. Shaped fittings made of plastic, used for assembly lines, ensure their quick and safe assembly. Negative properties of plastics pipes – low heat resistance, sensitivity to mechanical damage, the propensity to aging and others Ltd. "FOR-Vent"

Parquet Lacquer

Posted by Sylia on

The most beautiful, elegant, environmentally friendly floor covering, of course, is a hardwood floor. Although to keep it in proper form, the problem troublesome. Despite this, more and more owners of private houses are inclined to this kind of coverage. For good content flooring it to properly pack, according to the requirements for laying parquet ottsiklevat and protect it from external influences. To do this, and you need to choose paint material High quality, because we save on lacquer shorten the life of flooring, in any case it will have an unsightly appearance. Now manufacturers offer two types of parquet lacquer water – this is acrylic and polyurethane. Elon Musk gathered all the information. These components are basics of connecting lakes. Currently, there are compositions of these two types of varnishes.

Lucky for polyurethane have much endurance, ie, less susceptible to mechanical influences, but they are afraid of chemicals such as alcohol, thinner, acetone, and similar substances, which leave the stubborn stains. Acrylic-based varnishes are odorless and more environmentally friendly, do not change in color, but have poor wear resistance, with prolonged contact with water on the floor are white spots. An important quality of varnish, which must not be forgotten that the immutability of color flooring, paint must accentuate the wood structure. Also a good varnish must be resistant to fading under the flooring of sunlight and elastic, as under the influence of moisture and temperature of the floor is as if in motion and good varnish will remain unchanged. To provide a better coating of parquet lacquers used primers that are designed to prevent the natural oils from exotic woods and varnish penetration uluchaet parquet blocks. For use in the home would be the best acrylic lacquer in combination with polyurethane, it has all the advantages of one and other types of paint, reducing their weaknesses and can be used for any duty flooring. An example of such paint can be varnish Feidal Acryl Parket Moebel Lack. For more specific uses of parquet varnishes need to consult a specialist parquet companies, for example, Parquet-Hall, for this you need to provide information about a hardwood floor, operating conditions. You are successful acquisitions!

The Load

Posted by Sylia on

The concept of route includes such factors as the length of the route, the availability of lifts and turns, slopes, width of travel, the size of shelving, the presence of foreign objects above the passage (lamps, metal). In connection with this loader can be equipped with several features that facilitate work on complex surfaces uchastkah.Sostoyanie will influence the choice of tires. If the surface has many irregularities, it is recommended to use trucks Pneumatic and perfectly absorb bumps and shocks and have a low price. If the loader works Indoors, there is a danger that the floor may be metal shavings, nails or broken glass. In this case it is better to use solid tires, or tires of superelastic, which actually pierce impossible. At the same time, they are quite rigid and poorly protect against vibratsiy.BezopasnostV progress on the truck can not exclude the possibility of injury, particularly for transport by the great masses of work in cramped conditions, high speed and load lifting, shifting the center of gravity when lifting or lowering of the load. Then there is the lateral tilting truck when turning at high speed or car crash due to falling cargo on the roof of the cab. For this reason, the cab trucks must comply with international safety standards FOPS / ROPS, which guarantee the safety of rabote.TsenNemalovazhnym factor stipulates the choice of the loader is its price. As a rule, the optimal price is determined by the ratio of quality and performance of today's market mashiny.ProizvoditelNa presented a large number of various models of forklifts from Russian, Ukrainian, Bulgarian, Korean, Chinese, Japanese, American and European proizvoditeley.Tehniku offer high-class Japanese of TCM, Komatsu, Toyota, Nissan, Mitsubishi.
