Technical features of using JIS G3454 pipes
The JIS G3454 standard regulates technical requirements for seamless and electric-welded carbon steel pipes intended for use in pressure systems. These metal products, supplied by EV Group China, are optimal for industrial pipelines where the operating temperature does not exceed 350°C. For systems requiring operation at higher pressure parameters, JIS G3455 specifications should be used.
Expert notes on standardization:
- When ordering electric resistance welded pipes from EV Group China, the customer has the option to expand product quality requirements according to Z3 (ultrasonic defect detection) and Z4 (eddy current testing) specifications.
- All physical quantities provided in JIS specifications comply with the International System of Units (SI). When designing engineering systems using these products, it is necessary to consider current conversion factors to ensure calculation accuracy.
