The pipeline is a serial pairing of pipes, all kinds of elements and measuring equipment, which were provided for in the preparation of the project. If you decide to start laying the pipeline, then the question will arise before you about how to connect a metal pipe to a metal one. To carry out these works, one of the many methods can be used, however, the most suitable one is selected depending on the purpose of the system, as well as the conditions under which the operation will be carried out. Important is the size of the material and pipes.
During the installation of the pipeline, the most various ways of pairing pipes are used. Some of them suggest the possibility of a connector, which is required for dismantling and re-subsequent assembly. So, if you are thinking about how to connect a metal pipe to a metal one without welding, then you will have the opportunity to disconnect the elements during operation. Other compounds are monolithic. It will be impossible to disassemble them without breaking the pipes. The most common form of fixed joints is welding. It is used when working with all kinds of pipes. Among them are plastic, cast iron, steel and copper. However, the technology, which involves the use of welding, is far from the only method that is used when connecting pipes to each other.
Connection methods
Today, metal pipes are used quite often, which is why home craftsmen and specialists in their field are faced with the question of how to connect a metal pipe to a metal one. Despite the fact that plastic is used everywhere today, steel products are used to supply water and install pipelines, as well as arranging other types of systems.
Welding steel pipes is considered the most common installation method. Performing these manipulations requires the master to have skills and professional knowledge. Therefore, when making a pipe connection with your own hands, quite often masters refuse to carry out welding work.
Flange connection
Before connecting a metal pipe with a metal one, it must be taken into account that in addition to all the technologies listed in the article, there is also a threaded one. But if you decide to use pairing using flanges, you should know that this technique is also quite common. To perform such work, a special fitting called a flange is used. This item has a rubber gasket.
Flange joint technology
In order to use flanges for interfacing steel pipes, it is necessary to cut the product. It should be located strictly perpendicular, among other things, it must be removed from the burrs. There is no need to chamfer at the end. A flange is put on a previously made cut. At the next stage, a rubber gasket is installed so that it protrudes beyond a 10 centimeter cut. The connecting element is put on the gasket, and after it will be connected to the counter flange, the last of which should be installed on the part of the pipe that is supposed to be connected to the first.
If you were faced with the task of how to connect a metal pipe with a metal one, then in the process of twisting the connecting flanges you can not tighten the bolts.
Coupling Connection
A sufficiently tight and reliable connection is considered to be a coupling. It is used in the installation of pressure and pressureless piping systems. The technology for its implementation will be described in detail below.
Methodology
If you are thinking about how to connect a metal pipe to a metal pipe without thread, you can use a sleeve connection. To do this, the ends of the pipes, which are supposed to be joined together, need to be cut so that the cut is strictly perpendicular and even. A coupling should be applied to the joint, the central part of the fitting should be located at the junction. On the connected elements, you need to put a mark with a marker to indicate the position of the coupling. The ends of the products are treated with silicone grease, as is the coupling itself. The first pipe is inserted into the last to the indicated line. After the second pipe is aligned on a single axis with the first. The coupling must be pulled over it. When putting on the connecting element, you need to focus on the previously applied tags.
Galvanized pipes
Quite often, when laying water supply systems, the masters face the question of how to connect a metal pipe to a metal one without thread. But what if you have to use special types of pipes? Then it is necessary to carefully approach the issue of choosing the technology of their connection. Thus, if galvanized pipes are used when laying the pipeline, then it is impossible to resort to traditional welding methods. This is due to the fact that zinc is characterized by a certain melting point, which is much lower compared to that of steel pipes. This indicates that the zinc coating may burn out. In this case, the junction will be devoid of a special protective coating. These processes will certainly provoke the occurrence of corrosion. Couplings are often used to connect galvanized steel pipes.
Casing
Before connecting metal pipes, it is recommended that you familiarize yourself with all the technologies for carrying out these works. If you have to use casing used in the construction of wells, including those that will be used to supply water to residential buildings, the technique is selected depending on specific conditions. The most relevant method for casing is the welding method or installation of couplings. The choice of technology will depend on what products of what diameter are to be used for the arrangement of wells. Before connecting a metal pipe with a metal one, it is recommended to consider the photo. They are presented in the article. In confirmation of the above, it can be noted: if the pipe has a diameter of less than fifty millimeters, then the most convenient way is to use a sleeve connection. If the pipe diameter exceeds one hundred millimeters, in this case it is recommended to use welding.
Profile pipes
If you are thinking about how to connect a metal pipe to a metal one, the basic methods presented in the article will help you cope with this task. If you have to work with profile pipes, then welding is most often used to connect them. But in some cases, experts recommend abandoning this technology in favor of installing clamps. Such products are practically not used for the installation of pipelines that are intended for transporting liquids. This is due to the fact that in products of square or rectangular shape creates an impressive internal resistance.
