The main points of the cylinder is the boiler equipment, telephone 18112057236 welcome to inquire, for distribution to the boiler steam generated when the pipeline to go separate ways, sub-cylinder line pressure equipment, is a pressure vessel, the pressure ability, capacity and ancillary boiler should correspond. The main sub-cylinder pressure components are: head, shell materials. The main sub-cylinder pressure components are: head, shell, flange materials are Q235-B, 20 #, Q345R, specification model: ф159-ф1500, working pressure 1-2.5MPa, working temperature: 0 ~ 400 ℃, working medium: steam, hot water, compressed air. Special specifications can be designed according to user requirements prior arrangement. First, sub-cylinder uses: also called sub-sub-cylinder drum, it is essential for steam boiler ancillary equipment, sub-cylinder ?? widely used in power generation, petrochemicals, steel, cement, construction and other industries. Second, the structure of a sub-cylinder performance, sub-cylinder is the main equipment of the boiler, steam boiler used to allocate the resulting runtime pipeline to go separate ways, sub-cylinder line pressure equipment, is a pressure vessel. The main function is to allocate sub-cylinder steam, so there are multiple connections main steam valve seat and valve on points with steam cylinder, so that at each of the points needed to steam cylinder. The main points of the cylinder pressure parts for: with steam valve, main steam valve, safety valve door, trap seat, seat gauges, thermometers seat; head, shell, flange materials are Q235-A / B , 20g, 16MnR, specification model ф159-ф1500, working pressure 1-2.5MPa, working temperature: 0 ~ 400 ℃, the working medium: steam, hot water, compressed air. 2, range, a wide range of applications. Working pressure up to 16Mpa. 3, product quality assurance. Each sub-cylinder according to national standards for manufacturing, testing and acceptance. Sub cylinder factory after factory inspection by the local Quality and Technical Supervision detection factory supervisor to ensure that the quality of sub-cylinder foolproof. Inspection sub-cylinder prove drawings. Third, the sub-cylinder steam when the media specifications, should be "Pressure Vessel Code" provides the design and determine the cylinder diameter, material and thickness, the general principle: the cylinder diameter should be 2-2.5 times the diameter of the largest takeover in general fluid flow can be determined in vivo barrel, material 10-20 # seamless, Q235B, 20g, 16MnR plate rolling, to take over the number determined by the engineering design. 1. Equipment specification points cylinder specifications for DN200-DN1200, the specific volume of the container is determined by the user, the design pressure is generally 1.43MPa, design temperature <350 ℃, the working medium is steam, container-category Ⅰ pressure vessel. 2, users have special requirements, can be designed and manufactured in accordance with sub-cylinder needs of users. Fourth, the technical parameters: 1, to provide flow, pressure, temperature parameters. 2, to provide inlet, a gas, drain pipe diameter, number. 3, if the requirements of sub-cylinder sizes. 4. Do you want to pressure gauges, thermometers, safety valve five sub cylinder features: 1, standardized production. B regardless of the size of its sub-cylinder products are used girth automatic welding process, the product is beautiful, safe and reliable. 2, range, a wide range of applications. Working pressure up to 16Mpa. 3, each sub-cylinder according to national standards for manufacturing, testing and acceptance. After the factory inspection by the local Quality and Technical Supervision detection monitoring points cylinder plant at the factory. Ensure the quality of sub-cylinder foolproof. Inspection sub-cylinder prove drawings. 4, users have special requirements, may be required under sub-cylinder design and manufacturing users. Sixth, how to properly select a sub-cylinder, in line with the requirements of the design pressure first, followed by the selection meet the requirements of sub-cylinder, 2, is to look at the appearance. Appearance of the product reflects the quality and value of its 3, is to look at the product nameplate. Should be marked on the nameplate production name and date of manufacture enterprises, supervisory inspection units, whether in the upper right corner of the nameplate supervisory inspection seal unit 4, is to look at quality assurance. In accordance with relevant state regulations, each sub-cylinder factory must be equipped with a quality assurance, quality assurance is to demonstrate the importance of the sub-cylinder prove a qualified, standardized production. B regardless of the size of its sub-cylinder products are used girth automatic welding process, the product is beautiful, safe and reliable.
