Nickel-based alloys are alloys that have a combination of high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000 °C. Nickel alloy seamless tubes are widely used in petroleum, chemical, high pressure boilers, nuclear power, aviation, marine engineering, environmental engineering and other fields. Compared with ordinary stainless steel, nickel-based alloys have superior high temperature resistance, corrosion resistance and high strength properties. It is suitable for strong acid and alkali and high temperature environments under severe conditions. According to the main performance, it can be divided into nickel-based heat-resistant alloy, nickel-based corrosion-resistant alloy, nickel-based wear-resistant alloy, nickel-based precision alloy and nickel-based shape memory alloy. Nickel-based heat-resistant alloy: nickel-chromium (Ni-Cr) alloy, the main alloying elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, z...

Principle and characteristics of T-fin tube 1, the principle of T finned tube T-finned tube is formed after the rolling process is one kind of efficient heat transfer tubes by the light pipe. Its structural feature is to form a series of spiral annular T-shaped tunnels on the outer surface of the pipe. When heat medium outside the tube is formed in a tunnel in a series of bubble nuclei, four weeks in a heated state to a mountain tunnel chamber, the rapid expansion of the bubble nucleus lumen is filled, continuously heated rapidly increases the inner pressure of the bubble, a fine bubble from the tube surface to promote Squirting quickly in the seam. When injecting of bubbles with a large force erosion site, and a certain partial vacuum, so that the surrounding temperature of the liquid pouring into the lower T-shaped tunnel, the formation of continuous boiling. In this boiling mode, the unit surface area r} takes away much more heat per unit time than the light pipe, and this typ...

If a ship, for instance, is steam powered, two or more boilers will be provided to produce high temperature, high pressure steam. On the other hand, if a ship is powered by a diesel engine as the main propulsion system, then one or two small boilers are used for running various ship’s machinery and services. It is essential to keep boilers running to their full potential to make all the difference to a maritime operation, for a number of different reasons. Always remember, the smoother the boiler’s operation, the more effective it will be in its performance. How Boilers Work? The main job of a boiler is to produce high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure. Inside the boiler, the fuel is burnt in a combustion chamber. Air is supplied to this combustion chamber through a separate arrangement to attain ...

High Flux Tube Heat Exchanger High flux tube is bare tube evenly coated with a thin layer porous metal with multiple micro pores and interconnected tunnels. Surface porous coat not only increases heat transfer area, but also forms innumerable nucleation site to largely increase nucleation rate. Interconnected pores can also agitate local liquid during bubbling process, further increasing heat transfer coefficient outside tube. With synergy of many enhancements, heat transfer efficiency is greatly improved. Features Compared to bare tube, heat transfer area can be reduced by 27.5%. Equipment operation capacity can be increased by 20%. Total heat transfer coefficient is increased by 89%. Boiling can be achieved by lower temperature difference. The requirement of heat source temperature is decreased with outstanding energy conservation effect. Application Widely used for reboiler, evaporator, condenser and so on when there is phase transition. Tube Specs Diameter: ф12...

铝翅式换热器 : (1)传热效率高，由于翅片对流体的扰动使边界层不断破裂，因而具有较大的换热系数;同时由于隔板、翅片很薄，具有高导热性，所以使得板翅式换热器可以达到很高的效率。 (2)紧凑，由于板翅式换热器具有扩展的二次表面，使得它的比表面积可达到1000㎡/m3。 (3)轻巧，原因为紧凑且多为铝合金制造，现在钢制，铜制，复合材料等的也已经批量生产 。 (4)适应性强，板翅式换热器可适用于:气-气、气-液、液-液、各种流体之间的换热以及发生集态变化的相变换热。通过流道的布置和组合能够适应:逆流、错流、多股流、多程流等不同的换热工况。通过单元间串联、并联、串并联的组合可以满足大型设备的换热需要。工业上可以定型、批量生产以降低成本，通过积木式组合扩大互换性。 (5)制造工艺要求严格，工艺过程复杂。 (6)容易堵塞，不耐腐蚀，清洗检修很困难，故只能用于换热介质干净、无腐蚀、不易结垢、不易沉积、不易堵塞的场合。 铜管套翅片: 铜管套翅片散热器，涉及一种散热器。主要是为解决现有的铜管铝翅片散热器铝翅片与铜管接触不严密，有空隙，影响散热，翅片易松动的问题而研制的。它包括铝翅片和铜管，这里主要是将铜管横截面制成多边形。优点是铜管与翅片接触紧密，无空隙，热阻小，散热好，铝翅片不易松动。 Links to Lord Fin Tube: Studded Pipe LL Finned Tube KL Finned Tube HH Finned Tube Embedded Finned Tube HFW Solid Finned Tube HFW Serrated Finned Tube Extruded Serrated Finned Tube Finned Tube Heat Exchangers
