ASTM A519 1018 seamless steel pipe is a seamless steel pipe made of carbon structural steel.

The processing of brazed spiral finned tube is carried out in two steps. First, the steel strip plane perpendicular to the axis of the tube is wound on the outer surface of the tube in a spiral line manner, and the ends of the steel strip are welded to the steel pipe and fixed, and then the steel strip and steel pipe are welded together by brazing in order to eliminate the gap between the steel strip and the steel pipe contact.

JIS SS400 hollow steel pipe is a structural carbon steel hollow steel pipe produced in accordance with Japanese Industrial Standards (JIS). Mainly used for general structural purposes, such as bridges, buildings, machinery and other fields.

ASTM A209 specifies the requirements for various grades of minimum wall thickness seamless carbon-molybdenum alloy steel tubes. These grades include T1, T1a, and T1b, which are different in terms of their chemical composition and mechanical properties.
