Stainless steel tube plate flange

The so-called tube plate is a kind of accessory that drills out a slightly larger hole than the outer diameter of the pipe on the steel plate and penetrates the pipe into the welding and fixing it. In the calculation of fixed tube plate according to the temperature difference of various working conditions to calculate the axial stress of the shell, the axial stress of the heat exchange tube, the tension between the heat exchange tube and the tube plate, there is a can not meet the strength (or stability) conditions, it is necessary to set the expansion joint. In the strength checking calculation of fixed tube plate, when the thickness of tube plate is determined and no expansion joint is set, sometimes the strength of tube plate is not enough. After the expansion joint is set, the thickness of tube plate may meet the requirements. At this time, the expansion joint can also be set to thin the tube plate, but it depends on the comprehensive evaluation of material consumption, manufacturing difficulty, safety and economic effect. U-shaped expansion joint is commonly used in fixed tube-and-plate heat exchangers. It has the advantages of compact structure, simple, good compensation and cheap price. Tube plate is mainly used in chemical containers, such as tubular heat exchanger, pressure vessel, boiler, condenser, central air conditioning, evaporator, seawater desalination, plays the role of supporting fixed tube, metal material makes it not only has a strong rigidity, but also has a great heat conduction performance.

Since the very beginning of establishment, the company has been strictly keeping conformance to the requirements of international quality assurance system to manage production. Customer first, quality first is our consistent business philosophy, do a good job of each pipe fitting, strictly control each process, according to the standard inspection, products before leaving the factory to ensure that fully qualified. Looking forward to supporting your project!
