(1) JISG3452 The numerical value of carbon steel pipe for piping is shown. (2) JISG3442 The numerical value before plating of the water galvanized steel pipe is shown. (3) w Indicates the weight [kgf / m] of the steel pipe without socket plating. (4) Sch.Is an abbreviation for the call schedule. (5)The basic numerical value of the thickness of each schedule pipe is shown. marks are only carbon steel pipes for pressure piping, but other values ??are common to carbon steel pipes for high temperature piping, steel pipes for low temperature piping, and alloy steel pipes for piping. The tolerance of the outer diameter of the pipe is in the range of 0.5 to 1.0% for each type (hot finish / cold finish), and the tolerance of the thickness of the pipe is } 0.5 [mm] to 12.5% ??for the hot finish pipe. , Cold finish pipe is 0.2 ~ 0.3 [mm] ~ 10 [%] There are provisions for each type to some extent. | |||||||||||||
