Exchanger tubes are very popular in the boiler and heat exchanger industry, water heater industry, air conditioning industry, etc. Stainless steel heat exchanger tubes have many properties such as corrosion resistance, good ductility, lightweight, fatigue resistance, low and high-temperature resistance. The stainless steel tube heat exchanger is suitable for transporting all kinds of gases and liquids with extremely low and high-temperature requirements. They are also known as stainless steel spiral heat exchanger.
Stainless Steel Tube Coil heating exchanger is serpentine grade 316 stainless steel tube heat exchanger or 304 Stainless Steel. This heating exchanger has excellent corrosion resistance to most chemicals, salts, and acids. The main advantage is to circulate liquid, vapor, refrigerant with low pressure, very high-efficiency heat exchange, no leakage and resistance to high pressures. Stainless steel U tube is U-shaped tube heat exchangers are designed for high-temperature applications, especially hot oil or steam condensing systems. These stainless steel Utubes are sold in many industries/markets, due to their overall corrosion resistance and good machinability.
They are used for heat exchanging, in the field of Chemistry and Petrochemicals, Energy production, Recycled energy, Pulp and paper industry, Industrial pipelines, Mechanical work, Pharmaceutical / Petrochemical, Food and Beverage Industry. Corrugated stainless steel tubing heat exchanger are Stainless steel corrugated pipes, they are shaped like spiral grooved stainless steel pipes and are obtained from the smooth pipe by cold forming. It can be used for the connection of soft and flexible stainless steel pipes and has features such as good protective displacement and low vibration and noise.
High and low-temperature high pressure Resistant to a variety of delivery media, the hose can operate at high-pressure hydrothermal water, high-temperature steam, high-pressure hydrothermal compression distribution temperature gases, oils, organic solvents, corrosive liquids gas. On other hand, media widely used Stainless steel heat exchangers are particularly advantageous because they do not require the use of system inhibitors and are, in fact, compatible with clean running water. This means that little maintenance is needed to keep the stainless steel heat exchanger in good condition. Stainless steel U-bending pipes and tubes are used to prevent emissions due to applications.
In refinery applications, these carbon steel U-bend pipes and tubes also prevent the mixing of gases with other harmful gases and from escaping to the exterior surface through the drainage system. Stainless steel Finned tubes are a range of tubes used in applications involving the transfer of heat from a hot liquid to a cold liquid through the pipe wall. In other words, finned tubes use their “fins” to increase the area that the external fluid is exposed to. The tube then exchanges heat between the fluid inside the tube and the fluid outside the tube.
