304 stainless steel pipe weld flaw detection service

304 stainless steel pipe weld flaw detection service

The non-magnetic and coarse-grained characteristics of 304 stainless steel can effectively detect internal and surface defects such as cracks, pores, and slag inclusions using low-frequency ultrasonic probes (1.5-3.5 MHz) or digital radiography technology, ensuring that the quality of welds meets the requirements of standards such as GB/T 11345 and ASTM E164.
The flaw detection process includes weld pretreatment, equipment calibration, defect location and rating, which is suitable for pipeline welding quality verification in industries such as construction, chemical industry, and food machinery, especially for pressure equipment and welds in highly corrosive environments.
International standards
ASTM E164: Ultrasonic testing standard;
ISO 17640: Nondestructive testing of welding - ultrasonic testing.
Special requirements
High-risk industries such as nuclear power and petrochemicals may require compliance with standards such as ASME BPVC Section V or API 521.
