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 490, JIS G3466 STKR 500, and more, all tailored to meet specific
industry requirements.
