JIS G3461 specifies the carbon steel tubes used for heat exchange in boilers, heat exchangers, condensers, and similar equipment.

JIS G3461规定了锅炉、热交换器、冷凝器和类似设备中用于热交换的碳钢管。

JIS G3461 is a Japanese Industrial Standard that specifies the carbon steel tubes used for heat exchange in boilers, heat exchangers, condensers, and similar equipment. These tubes are designed to transfer heat both on the inside and outside of the tubes, such as water tubes, smoke tubes, superheater tubes, air preheater tubes, condenser tubes, catalyzer tubes, and more.

JIS G3461 was first issued in 1988 and was last updated in 2019. It is based on international standards ISO 9329-2 and ISO 9330-2 but with modifications to meet the technical requirements of Japan's industries.

JIS G3461于1988年首次发布，最后一次更新是在2019年。它基于国际标准ISO 9329-2和ISO 9330-2，但经过修改以满足日本工业的技术要求。

This standard specifies the technical requirements for seamless and welded carbon steel tubes with properties suitable for high-temperature service. The tubes must be heat treated, either normalized or quenched and tempered, depending on their manufacturing process.

本标准规定了适用于高温环境的无缝和焊接碳钢管的技术要求。管子必须进行热处理，根据其制造工艺，可以正火或淬火回火。

JIS G3461 is a Japanese Industrial Standard that sets the guidelines for the manufacture of carbon steel tubes used in various types of heat exchangers and boilers.

JIS G3461是日本工业标准，为各种类型的热交换器和锅炉中使用的碳钢管的制造制定了指导方针。
