Philips Metal Industries is a trusted manufacturer and exporter of stainless steel 304 heat exchanger tubes. We can provide our buyers with high-quality tubes at the lowest market prices. Our Stainless Steel 304 Heat Exchanger Tubes are austenitic stainless steel with a low carbon and high chromium content alloy. The lower carbon percentage prevents carbide precipitation during forming and welding. It is also commonly used for welding. Our Stainless Steel 304 Heat Exchanger Tubes are well-known in the industry for their fatigue resistance, high and low temperature resistance, durability, flexibility, corrosion resistance, lightweight design, and extended service life.
Welded tubes are more affordable than seamless tubes. They are preferred for low-pressure systems since they are less expensive. Seamless tubes are preferred in high-pressure systems due to their superior longevity and resistance to corrosion. Applications for stainless steel 304 heat exchanger tubes include energy and heat transfer, chemical processing, and refrigeration systems. The tubes in heat transfer move heat from one fluid, such a gas, to another, like a liquid. Heat exchanger tubes are used in energy transfer to create electricity by transferring heat from power plant combustion to water, which creates steam that powers turbines.
304 stainless steel heat exchanger tubes have shown themselves to be a dependable and adaptable material across a variety of sectors. They are available in two varieties, seamless and welded, both with advantages and uses. Many applications, including energy and heat transfer, chemical processing, and refrigeration systems, call for the employment of these heat exchanger tubes. They have many advantages, such as excellent corrosion resistance, longevity, sanitary qualities, and sustainability.
The strong Seamless Heat Exchanger Tubes are made with no welds or seams. This allows the tubes to work in high-pressure and high-temperature environments. Because they are made of high-strength materials, these tubes resist punctures even under the most severe circumstances. They can be made in configurations 304 or 316. Because of its improved nickel and chromium content during production, SS 304 Heat Exchanger Tubes have increased resistance to oxidative and corrosive media. In contrast, the SS 316L Heat Exchanger Pipe is a low-carbon grade that has an excellent nickel, chromium, and molybdenum content. It performs marginally better than the SS304 composition due to the content. Contact us or stop by if you have any questions or concerns about our products or would want to personalize them. We will be happy to assist you.
