Product Description

JIS G3454 Carbon Steel Pipe

JIS G3454 Carbon steel pipes for pressure service at an approximate maximum temperature of 350℃.

Carbon Steel JIS G 3454 Tubes are manufactured as per JIS Specification. CS JIS G3454 Seamless Tubes mechanical properties can be varied greatly by heat treating. Carbon Steel JIS G3454 Specification Covers Carbon steel tubes for machine structural purposes. CS JIS G3454 pipes are used for pressure conditions at an limited of maximum temperature of 350 Degree C. Carbon Steel JIS G3454 Tubes are mainly used in automobile, hydraulic system and precision machinery parts for cars and cylinder.

JIS G3454 Carbon Steel Grade STPG 370 Specification Covers Carbon Steel Tubes for Pressure Service. We offer CS JIS G3454 available grades STPG 410, STPG 370 and a diverse range of finish options to meet the appearance requirements and performance for most applications.

The tubes shall be manufactured by seamless process, electric resistance welding process, or butt welding process, and those of other grades shall be manufactured by seamless process or electric resistance welding process. The tube shall be as manufactured or as cold-finished condition, or they shall be subjected to appropriate heat treatment.

The tubes shall be practically straight. and the two ends shall be at right angles to the axis of the tube. The tubes shall be free from defects detrimental to practical use.

Method of Sampling Specimen

Division	Method of sampling specimen and number of test pieces
Nominal diameter, 50 A or under	On shall be taken form each 1000 pipes of its fraction of the same dimensions (2)
Nominal diameter, 65 A or over up to and incl. 125 A	one shall be taken from each 500 pipes or its fraction of the same dimensions
Nominal diameter, 150 A or over up to and incl. 300 A	One shall be taken form each 250 pipes of its fraction of the same dimensions
Nominal diameter, 350 A or over	One shall be taken form each 150 pipes or its fraction of the same dimensions

Note (2) The expression "same dimensions" means the same outside diameter as well as the same wall thickness.
