It is mainly used in chemical containers, such as tubular heat exchangers, pressure vessels, boilers, condensers, central air conditioners, evaporators, seawater desalination, and plays the role of supporting fixed tubes. The metal material makes it not only has strong rigidity, but also has great heat conduction performance. The tube sheet processing begin with the lathe machining the outer circle, upper and lower surfaces, steps, positioning slot, surface milling slot，and then into the drilling process, for special requirements, some tube plates/sheets after drilling have to continue to locate the hole and milling the slot according to the required depth，that will improve the pulling force and tightness of the expansion tube

Storage tank is not filled with water, but different properties of liquid and gas, petroleum, chemicals, acid and alkali, alcohol, gas, liquid, etc., according to the actual storage medium is different, the storage tank needs to be built into different shapes, the most common two are: like a thermos cup "cylinder" and like a ball "sphere". Metal storage tank Carbon steel storage tank, stainless steel storage tank, aluminum, etc Non-metal storage tank Plastic storage tank, ceramic storage tank, fiberglass, etc Metal and non-metal composite storage tank Steel lined polyethylene, steel lined polyolefin, steel lined rubber, etc Standard

Shell And Tube Heat Exchangers are devices that transfer part of the heat from the hot fluid to the cold fluid, allowing hot water to flow through the pipe due to the temperature difference between the hot water in the pipe and the cold water in the container. Wall heat exchanger Two fluids with different temperatures flow in the space separated by the wall, and heat is exchanged between the two fluids through the heat conduction of the wall and the convection of the fluid on the wall surface. Regenerative heat exchanger Heat is transferred from high temperature fluid to low temperature fluid through the heat accumulator composed of solid material, so as to achieve the purpose of heat transfer.

Advantages / Features: The heat treatment automation line adopts advanced whole quenching techniques to manufacture the roller and it can meet the technical requirement of the roller. The controlling and inspecting to the production line are all fulfilled by computer system with advanced control mode and inspection method. The flexible roller assembling line introduces multiple working stations. The rollers are automatically washed before assembling by the washer to guarantee the cleanness and sealing performance of the production.

The material of the carrier roller body is forged by 40Mn2. and the surface heat treatment HRC 48-55 depth up to 5-8mm. Precision CNC machine machining size is more accurate The center shaft of the carrier roller material is 42CrMo and forged .The hardness of surface heat treatment can reach 48-55HRC More wear-resisting . Core hardness of HRC 28 or above is not easy to fracture. Tempering 180 degrees before finishing. The surface of the center shaft of the carrier roller is polished by CNC machine tool to make the shaft smoother. High sealing aprons are used inside the carrier roller to prevent dirt, sand and water from damaging it. The carrier roller using friction welding technology welding quality is good and stable, and environmental protection, no pollution.Welding process does not produce smoke or harmful gas, no splash, no lone light and spark, no radiation.Known as the green welding technology of the future.
