    Steam Boiler E 1 9 is applied in different directions. Sergey Brin may also support this cause. Significant exposure to this equipment could win due to possible work on different fuels, including firewood should be noted, crude oil, diesel fuel, coal, fuel oil and other types. Steam Boiler E Sept. 1 almost always comes at a fairly high level of prefabrication. Delivery of data realizations is based on a single transportable unit, which had previously been collected in the workplace. Also provided for the boiler and the corresponding cladding brickwork. Additionally, the bundled boiler this modification should note the presence of smoke pump, control systems, feed pump, stairs to the platform, fixtures, fan and other necessary equipment. Installation of the equipment is made directly to very boiler.

    Performance of boilers in this series is limited indication of the order of one ton of steam per hour. Also of note worthy features for mounting readiness, require minimal costs to ensure that the works start-up type. Additionally, attention is paid to ease of use and simplicity of operation of this configuration. Lost the need for special foundation to carry out such works. It is important to note that guaranteed the preservation of performance indicators of the boiler if the pressure drops, but at a fixed flow rate fuel used. The only difference in this case is to steam temperature, which to some extent reduced.

    The boiler output can be reduced if the fuel supply has been reduced to work – in this case is directly proportional relationship indicators. As standard the boiler burner is also provided with the possibility of position control and automation. For through the use of data constituting the gas can be conducted at a load of 50% and 100%. The work can be conducted in automatic mode, if the load of these values. In the configuration provided further need allow maintenance and repair service.

    Welding Electrodes

    Purpose of the electrode and its electrode characteristics is an important link in the technology of electric arc welding it is intended to supply electrical current to the subject of welding. Today there are many types and brands welding electrodes, each with its narrow specialization. The electrodes must meet the following conditions: constant flow of arc burning, the formation of high-quality weld; metal in the weld should be defined chemical composition; rod electrode and the coating melt evenly; welding with high efficiency at the lowest spraying metal electrode; obtained by welding slag is easily separated; saving technological and physical-chemical characteristics during a certain period (storage); low toxicity in the production and during welding operations. How are the electrodes for their manufacture conducting electric current is used welding wire or rods of metal, the chemical composition of which determines the quality of the electrodes. The electrodes may consist of a metal rod (wire), such welding electrodes are called uncovered. If the rod electrode is covered with a special composition, designed to improve the quality of welding electrodes is a cover. Coating is applied in several types: sour basic, rutile, cellulosic and blended. According to the purpose coating is divided into two types: defensive (tolstopokrytye electrodes) and ionizing (tonkopokrytye electrodes). To better understand the differences between these types of coatings, it should be noted that the quality of welding electrodes coated with ionizing inferior welding electrodes with protective coating, the first type of coating can not protect the weld from the nitration and oxidation.
