YUHONG GROUP are professional in heat exchanger tubes, heat exchanger assembly, like tubesheets, baffle plates, the heads, tube bundles, etc. 1. Tubes: Tubes are the main components of a heat exchanger where the heat transfer takes place. They are typically made of metal such as copper, stainless steel, or titanium. 2. Tube sheets: Tube sheets are used to secure the tubes in place and provide a seal between the tube side and the shell side of the heat exchanger. 3. Shell: The shell is the outer casing of the heat exchanger that houses the tubes and other components. It is typically made of metal and provides support and protection for the internal components. 4. Baffles: Baffles are used inside the shell to direct the flow of fluid and enhance heat transfer efficiency by creating turbulence in the fluid flow. 5. End caps: End caps are used to seal the ends of the heat exchanger and prevent leakage of fluids. They are typically made of metal and are securely fastened to the shell. 6. Headers: Headers are used to distribute and collect the fluid flowing through the tubes of the heat exchanger. They are typically located at the inlet and outlet of the heat exchanger. 7. Fins: Fins are used to increase the surface area for heat transfer in the tubes of the heat exchanger. They are typically attached to the outside of the tubes and can be made of metal or other materials. 8. Gaskets: Gaskets are used to create a seal between the tube sheets and the shell to prevent leakage of fluids. They are typically made of rubber or other flexible materials. 9. Support structures: Support structures such as brackets, stands, and feet are used to secure the heat exchanger in place and provide stability during operation. They are typically made of metal or other sturdy materials.

G Type Embedded Finned Tube G Type Embedded Finned Tube is that the fin strip is tension wound and placed in the groove cut into the tube with appr, 0.4mm groove depth, then the bottom of the fin is guided into the groove and backfilled with base tube Firmly, finally lock the fins in place by rolling the grooves enclosed in the bottom of the fins. The maximum operating temperature of G Type Embedded Finned Tube can reach 400°C.

23057 Heat Exchanger Parts- "Tubesheet" What is Tubesheet in HeatExchanger? A tubesheet is a component of a heat exchanger that is used to support and secure the ends of the tubes in the exchanger. It is typically a flat plate with holes drilled to accommodate the tubes. The tubes are inserted into the holes in the tubesheet and then expanded or welded to create a secure connection. The tubesheet serves several important functions, including providing structural integrity to the heat exchanger, ensuring proper alignment of the tubes, and creating a tight seal between the tubes and the tubesheet to prevent leakage.

YuHong 22191 ASME SB163 N04400+Aluminium G Type Fin Tube G-Type finned tubes are known as embedded-fin tubes where g means grooved. They are formed by twisting a fin strip made of copper or aluminium into a machined groove and back-filling to secure the lock. Base tube material is filled. The G-type fin tube is strong as compared to other tubes. Hence, it is widely used where high-temperature heat transfer is required. G-Type Finned Tube Features Compact design High-performance Easy installation Less space required Less cabling Optimized surface Finest technology used Average corrosion protection Less energy consumption Increased reliability Low maintenance High mechanical resistance

YuHong Group 11CR/ 13CR Studded Fin Tube Steel studded tubes are used instead of finned tubes for heat transfer in the petrochemical industry, generally in furnaces and boilers where the surface is exposed to a very corrosive environment and where very dirty gas streams require frequent or aggressive cleaning.

ASME SB111 C71500 70-30 Copper-Nickel Alloy Seamless Tube Copper pipes have a variety of uses and are made up of copper alloy. Cupro Nickel 70/30 Pipes And Tubes are one such variety that has 70% copper and 30% Nickel. We at victor Steel offer a wide range of Copper Nickel 70/30 Seamless Pipes in different sizes, shapes, and dimensions. They do not require any special material consideration and can be easily welded, fabricated and cold worked on. Copper Nickel 70/30 / Nes 780 are used in offshore flangs, propeller sleeves, shelf bodies, welding backing rings, and flexible metal hoses. It is resistant to corrosion in seawater due to the quick formation of the protective surface film when it is exposed to clean seawater. This layer can be brown, greenish-brown, or green in color.

YuHong 22113 ASTM B407 N08811 Incoloy800HT Seamless Pipe INCOLOY 800HT Seamless Pipes The INCOLOY® 800HT series of alloys offer good strength retention under exposure to extremely corrosive and high temperature environments along with having good creep and rupture strength. They have found wide usage in chemical plants, refineries and power generation facilities. Suitable applications are found in process piping, heat exchanger and furnace manufacture. Incoloy 800HT is primarily used in applications with temperatures up to 1100° F, where alloys 800H and 800HT are normally used in temperatures above 1100° F where resistance to creep and rupture is required. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. Incoloy 800HT will not become embrittled even after long periods of usage in the 1200-1600° F range where many stainless steels become brittle. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with 800HT. When cold formed extensively the grain size produces a visibly undulated surface called [orange peel". Incoloy 800HT can be welded by the common techniques used on stainless steels.
