Introduction to tube sheet flanges
The tube sheet flange is to drill a hole slightly larger than the outer diameter of the tube on the circular steel plate. It is a round steel used to fix the tube and seal the medium in the heat exchanger. The tube is penetrated into the hole and welded. A flange fitting for fixing.
With the enlargement of chemical equipment and power stations, the diameter of the tube sheet flange is also becoming larger and larger. The tube sheet flange with a diameter of 4m-5m is very common, or can be customized according to the customer’s drawings. Large flange tube sheet flanges are characterized by a large number of tube holes, dense, small and deep holes, high precision and smoothness requirements. The metal material makes it not only very rigid, but also has great thermal conductivity. Tube sheet flanges are widely used in chemical containers, such as tube and tube heat exchangers, boilers, pressure vessels and other industries, to support and fix the tubes.
As shown in the picture, the tube sheet flange customized for an old customer in Singapore is shown in the picture. The production, processing and testing are completed today, and it is expected to be sent to Singapore for the boiler project.
Haihao Group has specialized in the production of flanges for more than 40 years. Flanges of various sizes, materials, and types can meet the needs of customers, including tube-sheet flanges, and are widely praised by new and old customers.
