Stainless seamless heat exchange tubes are important heat exchange elements in industry, especially chemical production. So, do you know what advantages stainless steel heat exchange tubes have?
- One of the advantages of stainless steel heat exchange tubes: cost advantage.
First of all, the stainless steel heat exchange tube is made of high-quality stainless steel alloy, so the stainless steel heat exchange tube has strong shock and vibration resistance, can resist the impact of the conveying medium, reduce the leakage of the heat exchange tube, and naturally save the stainless steel heat exchange tube Replacement and maintenance costs.
In addition, different stainless steel materials are used in production and processing, and the consumption of stainless steel materials is different. Especially when the duplex stainless steel is used to produce stainless steel heat exchange tubes, its yield strength is more than twice that of 316L austenitic stainless steel, and it has sufficient plastic toughness for forming. The wall thickness of duplex stainless steel pipes is 30-50% smaller than that of 316L stainless steel welded pipes, and the production of stainless steel heat exchange pipes is beneficial to reduce costs.
In addition, different types of stainless steel heat exchange tubes have different consumption of stainless steel. For example, in the production process of stainless steel coils, the initial steel consumption can be reduced by 15%, and the steel consumption throughout the life cycle can be reduced by about 55%. Only the manufacturing process of the stainless steel heat exchange tube can save 84.25% energy than ordinary carbon steel, which naturally saves the production cost of the stainless steel heat exchange tube.
- The second advantage of stainless steel heat exchange tubes: heat exchange advantages.
This is because the stainless steel heat exchange tube is made of high-quality stainless steel alloy, so the stainless steel heat exchange tube has strong shock resistance and vibration resistance, and can resist the impact of the conveying medium. The use of 0.5-0.8 mm thin-walled stainless steel heat exchange tubes can improve the overall heat transfer performance. Under the same conditions of heat exchange area, the total heat transfer coefficient is 2.121-8.408% higher than that of copper tubes. In the production process of stainless steel heat exchange tubes, in order to eliminate welding stress, heat treatment is performed at 1050 degrees in a shielding gas to make the surface roughness meet the heat exchange requirements. The inner wall of most stainless steel heat exchange tubes is smooth, making the bottom thickness of the boundary layer flow thinner, which not only enhances heat transfer, but also improves the anti-scaling performance and enhances the heat exchange effect of the stainless steel heat exchange tube.
In addition, in the production of stainless steel heat exchange tubes, advanced production technology and equipment are used, and there are many high-tech production personnel and many years of production and management of stainless steel heat exchange tubes, so the quality of stainless steel heat exchange tubes produced is guaranteed , Under the correct use and maintenance, the stainless steel heat exchange tube rarely corrodes and will not affect the production activities.
Note:The seamless heat exchanger tubes is one of the components of the heat exchanger, and is placed in the cylinder for exchanging heat between the two media. It has high thermal conductivity and good isothermal properties. It is a device that can quickly transfer heat from one point to another, with little heat loss, so it is called a heat transfer superconductor, which has a thermal conductivity of several thousand times copper.
Heat transfer or thermal conduction is the transfer of energy by internal collisions of particles and movement of electrons within the material.
To summarize, the aggregate effect from all collisions results in a net flux of heat energy from the hot body to the colder body.
Broadly speaking there are two methods widely used for measuring the thermal conductivity of objects: Steady-state and non-steady-state (or transient) methods.
Some common thermal conductivity tests are Hot Disk Transient Plane Source (TPS), Heat Flow Meter (HFM),Transient Hot Wire Liquids (THW),Transient Hot Wire Solids (THW), Laser Flash Apparatus (LFA) etc.
Although the gathering and analysis of data is more difficult, this method is more convenient and less time taking.
For example the quality of soil in the area can be a potential risk to the inbuilt cables and pipelines.If a low heat conduction is gauged, cables and pipelines may possibly combust due to the exothermic reaction.
