Amardeep is a renowned supplier and exporter, known for delivering high-quality products in compliance with the JIS G 3466 Standard. JIS G3466 carbon steel tubes have a wide range of applications, primarily for heat transfer both internally and externally within pipes. These versatile tubes find utility as smoke tubes, superheater tubes, boiler water tubes, air preheating tubes, and related accessories. For JIS G3466 Carbon Steel Square Tubes, a low-temperature annealing or normalizing process is essential.
Similarly, JIS G 3466 Carbon Steel Rectangular Tubes also require low-temperature annealing or normalizing treatments, but it's important to note that they are not suitable for low-temperature services. Apart from heat transfer applications, these tubes can be used in the petroleum and chemical industries. Our product range includes various grades of carbon steel pipes, such as JIS G3466 STKR 400, JIS G3466 STKR 440, JIS G3466 STKR 500, and more, all tailored to meet specific industry requirements.
