A heat exchanger is process equipment designed to transfer heat between two fluids or between the surface of a solid and a moving fluid. The manufacture of the heat exchanger can be performed in different grades of stainless steel or special alloys. They can withstand high and low operating pressures and a wide range of process temperatures. In the manufacture of heat exchangers, welding is a key aspect of the process. The tubular heat exchangers are very efficient process equipment, and a high speed improves heat transfer considerably. Sizing of a tubular heat exchanger To carry out the dimensioning of  Stainless Steel Heat Exchanger Tubes , it is necessary to have certain starting data, such as the process flow, the initial and final temperature. An essential factor for the calculation and dimensioning of a tubular heat exchanger is to be able to characterize the behaviour of the product. It should be done in a reliable and precise way, through laboratory tests, where it is possi...

The plug valve is a kind of quick on-off through the pipe fittings. The friction caused by the movement between the sealing surfaces under the fully open condition can altogether avoid contact with the flowing medium. It can frequently be used for the medium with suspended particles. Also, plunger valves quickly adapt to a multi-port design where the valve can have two, three, or even four different ports. It simplifies piping design and reduces the use of valve and fittings. The plug valve features long service life and high reliability. This is a good choice for many corrosive, abrasive, toxic substances, continuous operation and other media and devices widely used in the chemical industry. Plunger valve advantages: One-piece top-entry body plunger valve design, simple structure, easy in-line maintenance, no leakage, and withstand a stronger Hastelloy C22 Tube The medium used in the chemical industry is highly corrosive. Therefore the valve body used in the chemical process must be ...

Non-magnetizable chrome-nickel steels and magnetizable chrome steels with a chromium content of at least 12% are designated stainless steel. The corrosion resistance of  Incoloy 800H Pipe  is due to a passivation layer that forms on the metal surface in contact with oxygen. The oxygen present in the air is sufficient for this. Chemically destroyed and oxidative damage will occur even if it is stainless steel. Furthermore, stainless steels are not completely resistant to some chemical compounds. Heavy layers of dirt that contain chlorine salts or foreign rust, in certain circumstances can produce over time colorations or corrosion on the  Inconel 600 Tubing  surface. WHEN HANDLING STAINLESS STEEL FURNITURE AND APPLIANCES, THE FOLLOWING BASIC POINTS MUST BE TAKEN INTO ACCOUNT: The stainless steel surface must always be kept clean and accessible to the air. Some deposits can cause corrosion under certain working conditions due to lack of oxygen. These marks of use, as w...

After curing the hardening, the hardness achieved by this material is not as high as that provided by 420  Stainless Steel Tube . Main applications of 410 stainless in oil refining equipment, valves, pump components and cutlery. By increasing the amount of sulfur, the stainless 420 F, and a variety of 420, are obtained, with good susceptibility to machines. Carbon additives (for higher hardness), chromium and molybdenum (also improve wear resistance) lead us to the Martensitic 440 type stainless steel, used for professional cutting knives.   Stainless steel from iron Stainless steel from iron is also magnetic. Although carbon is less than martensitics, it becomes partly austenitic at high temperatures and thus Martent precipitated during cooling. Arguably partially treatable by heat treatment. Iron stainless steels generally have higher chromium content than martensitics. This increase in the amount of chromium improves the wear resistance of various media, but it partially sa...
