The boiler tube refers to the steel that opens the two ends and has a large steel cut.The wall thickness indicates that its size range is wide, from a small diameter tube with a small diameter to a large diameter tube with a diameter of several meters.
Boiler tube welding
The word "boiler tube welding" of boiler tube welding has long been well known in those developed countries, and the production technology of boiler tube welding has also matured in developed countries and has been widely used.At present, as far as developing countries are concerned, such vocabulary can be said to be relatively unfamiliar, and it has not reached the point of being popular.In my country, it is still in the testing stage, and has not made great efforts to promote development. It is believed that in the future, it will become a trend of development.At present, the best way to use this technology and widely applied in China is to learn from foreign boiler tube welding technology, introduce the technologies of those developed countries and study, so that relevant technical personnel in their country are proficient in and used. This will greatly reduce the production cost of boiler tube welding technology in my country.In the word "welding", the word "welding" is composed of the words "fire" and "drought". However, these two words are known for high temperature. Obviously, the work of "welding" isThe extremely high temperature conditions are completed.To work, the staff requires a very high concentration.And before the "welding", "boiler" can be imagined to welded the heavier boiler with a heavier volume and add it in a high -temperature environment.It is also quite high.
Boiler tube specification
The specifications of boiler tube generally include GB/T3091GBT3094GB3087GB5310 Boiler Material: For low pressure with low pressure, 20g, 20g is Q245R.A material in steel is a boiler board.G is the first letter of "pot" in the boiler board: G. G.Execution standards: GB713-1997 (all internal and external standards perform this standard) applicable range: steel plate with thickness 6mm-150mm.Because the steel plate is delivered at a positive tolerance at the time of delivery, the boiler board also has a thick added value table.When calculating the weight of the steel plate in theory, it is necessary to add the corresponding values ??on the table on the basis of thickness.According to the requirements, heat treatment can be performed on the steel plate: controlling, right fire, etc.Explanation standard execution: JB/T4730.3-2005, divided into three levels.
Boiler tube material
Introduction of boiler pipe materials: 20G high -pressure boiler tube is a type of boiler tube, which belongs to seamless steel pipe categories.The 20G high -pressure boiler tube is often at high temperature and high -pressure conditions. Under the action of high -temperature flue gas and water vapor, the pipe will oxidize and corrodes.The steel pipe is required to have high persistence, high antioxidant corrosion performance, and good tissue stability.The 20G high -pressure boiler tube is mainly used to make high -voltage and ultra -high -pressure boilers heat tube, heat tube, pipe pipe, main steam pipe, etc.
