Pipes and their types

Pipes are classified depending on the application for: water pressure, sewer, gas, heating, and for cable, telephone and electrical wires. We will consider those that are directly related to your home plumbing. Pipes made of steel, like zinc, and not cast iron, plastic and ceramics. Separately, you can select stainless steel pipes, which are much longer than other steel pipes, looks pretty nice and do not require additional processing (eg, spraying) during the operation. There is also asbestos and metal pipes. How well the plumbing pipes, largely depends on the material from which they are made, and the quality of the workmanship. The latter continues to be desired. 0B evidenced by the annual summer-spring-autumn and sometimes winter repairs. You can not even leave the house, just look out the window. Vengeance roars excavator, gnawing into frozen ground, can hear cheerful shouts of foremen, tired men, without much enthusiasm to perform ordinary chores. It is - sad and, unfortunately, the inherent lyricism of our public life. But do not let the bad news, let's talk about the kinds of pipes, their features and advantages. Steel pipes So pipe. The most popular and familiar among them are galvanized steel pipes, and I must say, the full law. Steel has been and remains perhaps the hardest industrial material used in large-scale modern industry and for domestic purposes. In addition, we must tell you that further enhances the strength of steel pipes way of cooking. Two methods: welded and seamless. As the name suggests, the first method involves the use of welding and the inevitable seams at the joints in the field of welding. It is here that the most likely to cause defects in the case of low-quality connection parts of pipes in one whole. Therefore, the best quality and durable of all beings is a seamless, seamless tubes of steel, coated with a deposited layer of zinc (for some reason and called zinc). Seamless pipes are common, not assembled from components, which ensures their durability. A zinc, which may be borne by such tubes, saves you from having to take other extra measures to protect them from the formation of rust bloom. These tubes do not require priming and painting, except in places designated for the compounds (which are marked thread, and when this operation will inevitably damaged galvanizing). Do not be lazy to take care of it: setting in her apartment seamless galvanized pipe, primed and paint it on the ends, with image carving. If you have purchased non-galvanized seamless pipes, treatment should be subjected to the entire outer surface of the product. As welded and seamless pipe - galvanized or not - are interconnected with special devices with an unusual name for our ears - fittings, which we have already mentioned. Afraid of this word is not necessary. Fittings themselves are simple in appearance, they have another name - clutch. Have you seen them probably a hundred times, stopping the eye at the joints of pipes. Remember one thing: the steel pipes must connect to the same steel fittings, that is, products from the same material as the pipe. Why are we talking about? The fact that there is a bad tradition of joining steel pipes cast iron fittings, not of malice, but out of ignorance or negligence. What happens at the same time? Being in direct contact with pig iron, the material is subjected to corrosion treatment (galvanized steel), begins to be subjected to the destructive influence of iron, gradually rust and "death" sticks to the ineligible alien cast iron fittings. By itself, cast iron fitting is quite good and reliable, but its use is desirable in the collection of cast iron as components or in combination with other homogeneous metals. For steel, he will not do. We'll talk about fitting in the future, but now say only that this simple device is generally better to have a reserve in the pantry, and in several instances. You are curious to learn how to distinguish iron from steel. This will help you avoid mistakes when selecting pipes themselves, without professional assistance. So, read and do not panic. Express her on the metal, causing your doubts, a few drops of sulfuric acid, following the utter caution. Wait a bit - three or four minutes - and wash with water place that kapnuli. In any case, whether steel or iron on the metal will soon tread the characteristic spot. The whole point is, what it will be in color. If black, it means that before you steel. And rather than tread the black spot, the steel is better - a measure of the quality of tempering steel. If the tread is slick gray in front of you - a pipe made of iron. Do not be afraid that the stain will ruin the tube or at least its appearance, no! It is easily washed off with water. Depending on its thickness, the pipes are divided into three types: light, ordinary and reinforced. You should know that a considerable thickness of metal has a positive side (high corrosion resistant) and negative: they are worse and severe bend in the repair and installation works. Different steel pipe and the diameter, and stands out both external and internal diameter of pipes. The last we can see by looking through the tube to light as to why it is called the diameter of the light. Bore diameter is taken into account in major construction works. Cast iron pipes in home plumbing - the traditional material, which has its own reasons: it is relatively cheap, reliable enough, why, and continues to be an alternative to pipes made of stainless steel or metallopolimerov. As much as we may want to avoid this, again, has to dwell on the quality - it is as traditional for the domestic plumbing. Himself cast has got nothing to do with it. He has brought much benefit to mankind since the days when it learned of his produce. The whole point is to manufacture it, we often limping. Therefore, we have been telling you about the advantages of metal pipes, which are mostly made abroad, and the galvanized, seamless steel tubes. The latter are also made by domestic manufacturers, but the method of manufacture is largely guaranteed quality. How to detect flaws in cast iron pipe? Of course, in the first place through careful examination of its exterior surface. It should not be hills, valleys, gaps or cracks, foreign spots, indicating the presence of slag. Pay attention to the section of pipe: what is the quality of the metal itself? Tube wall along its entire thickness from the front to the inside should be uniformly fine-grained, dense, homogeneous. In addition, make sure your pipes by prostukivaniya: the sound should be smooth and hollow, and in places where the audio tone changes, probable internal defect. Here the situation - as with a sick tooth decay process which may take place under the outwardly prosperous look. To detect such damage and applies prostukivanie. Acquired iron pipe must be protected against corrosion, or in continuous operation, it does not serve you for a long time. One way to protect against corrosion is to coat the outer surface of the pipe with bitumen, which is made from petroleum. Of course, you can apply it themselves, having the right experience and materials. Further it is necessary to remind you how important it is correct, high-quality cast-iron pipe joint designs. You must have a high quality, oakum, made from hemp fibers and of sufficient length. Tow should be free from all impurities and does not contain a timber. Tow the timber can not properly perform its insulating function, resulting in a pipe soon begins to seep into the joints. Consequences are well known: wet ceilings or floors are rotten. Strictly speaking, we would not recommend you carry out installation of cast iron pipe to their homes in the absence of a specialist. The highest priority in our conditions still is holding this type of work a competent master, looking for work where you can learn a lot. Nuances and tricks here - a great multitude, as when you install the power system. Therefore, follow the wise rule: "I'm not sure - not try." But we have a concern that we scare you iron. Well, thank you! Everything will be fine. This is an excellent plumbing material and in the capable hands it becomes a powerful and reliable water supply network. Instead of cast iron, you can use ceramic tubes: both the first and second are successfully applied for external sewerage system. In addition, the ceramic tubes are protected from corrosive damage the special coating. Used for this purpose particularly resistant glaze, which is covered by both external and internal surface of the pipe. The walls of the ceramic tubes are thick - up to 40 mm, which is an excellent guarantee of strength, and are interconnected they are lighter than cast iron, this, in particular, promotes a particular form of the bell and the opposite, entering the mouth of the tube end. Ceramics in general have found themselves in plumbing the most widely used, and rightly so: it is economical, hygienic and safe material. Asbestos Pipe prices do not they have been, whether you have the opportunity to prepare himself asbestos-cement mixture, molded it and then gently put into the trench dug by a sewer, or into the recesses intended for drawing combustion products into the ventilation network. But you do that, unfortunately, can not - do not have the necessary equipment. So have to buy a ready-made. But this is not a nuisance - they are quite durable and relatively inexpensive. And here is transportation, so something on our roads can turn and high-quality asbestos cement pipes in the likeness of cracked glass ware, ready to flow. Here's to you - the trouble and frustration. So try to bring the pipe as possible with care, as it neatly and mount them. In this case, they will serve you reliably - can rest easy. Pay attention to their appearance when you buy: the joints must be tight and smooth. By the undeniable merits of the asbestos cement pipes is their ability to process the installation using special tools. Pleasantly different asbestos compounds and their nonsusceptibility to action sewage. They can be successfully used for the ventilation system. Asbestos - a material plumbing universal, it is used not only for closing sockets and repair of pipe joints, but also for the manufacture of pipes themselves.
