Rippenrohre-Hersteller in China

Rippenrohre ist ein Wärmeaustauschelement. Rippenrohre werden fast immer in luftgekühlten Wärmetauschern verwendet, um den niedrigen Wärmedurchgangskoeffizienten auf der Luftseite auszugleichen. Hersteller von Rippenrohren in China. Um den Wärmeaustauschwirkungsgrad zu verbessern, wird die äußere Oberfläche (oder innere Oberfläche) des Wärmeaustauschrohrs im Allgemeinen durch Hinzufügen von Rippen auf der Oberfläche des Wärmeaustauschrohrs vergrößert, wodurch der Zweck erreicht wird Verbesserung der Wärmeaustauscheffizienz. Rippenrohr ist eine Art Wärmetauscherrohr. Rippenrohr Hauptkatalog 1. Hauptleistungsanforderungen an Rippenrohre 2. Stand der Flossenrohrproduktionstechnologie 3. Klassifizierung der Rippenrohre Hauptleistungsanforderungen an Rippenrohre Als Wärmeaustauschkomponente arbeitet das Rippenrohr lange Zeit unter Hochtemperatur-Rauchgasbedingungen. Beispielsweise weist das Rippenrohr des Kesselwärmetauschers eine raue Umgebung, hohe Temperatur und hohen Druck

Fabricante de tubos con aletas en China

El tubo con aletas es un elemento de intercambio de calor. Los tubos con aletas casi siempre se usan en intercambiadores refrigerados por aire para compensar el bajo coeficiente de transferencia de calor del lado aire. Fabricante de tubos con aletas en China, para mejorar la eficiencia del intercambio de calor, el área de la superficie externa (o área de la superficie interna) del tubo de intercambio de calor generalmente aumenta al agregar aletas en la superficie del tubo de intercambio de calor, logrando así el propósito de Mejora de la eficiencia del intercambio de calor. El tubo con aletas es un tipo de tubo de intercambio de calor. Catálogo principal de tubos con aletas 1. Principales requisitos de rendimiento de los tubos con aletas 2. Estado de la tecnología de producción de tubos de aletas 3. Clasificación de los tubos aleteados. Principales requisitos de rendimiento de tubos con aletas Como componente de intercambio de calor, el tubo con aletas funciona durante

Finned Tube Manufacturer in China

Finned tube  is a heat exchange element. Finned tubes are almost always used in air-cooled exchangers to compensate for the low air-side heat-transfer coefficient. Finned tube manufacturer in China, In order to improve the heat exchange efficiency, the outer surface area (or inner surface area) of the heat exchange tube is generally increased by adding fins on the surface of the heat exchange tube, thereby achieving the purpose of improving heat exchange efficiency. finned tube is kind of heat exchange tube. Finned tube main catalog 1. Main performance requirements of finned tubes 2. Fin tube production technology status 3. Classification of finned tubes Main performance requirements of finned tubes As a heat exchange component, the finned tube works for a long time under high temperature flue gas conditions. For example, the fin tube of the boiler heat exchanger has a harsh environment, high temperature and high pressure and is in a corrosive atmosphere, which requires h

Nickel-based alloy seamless pipe

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

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
