surface cleaning method of seamless pipe:1. cleaninguse solvents and emulsions to clean the steel surface to remove oil, grease, dust, lubricants and similar organic substances, but it cannot remove rust, oxide scale (corrosion products formed by oxidation), welding flux, etc. on the steel surface,

the seamless pipe factory will have cracked steel pipes in the production of seamless steel pipes. it is not terrible to have cracks. we should investigate the cause and find a solution.no matter what material the seamless steel pipe is, the occurrence of cracking is inseparable from the influence o

characteristics and application of magnetic flux leakage detection method for seamless steel pipe (smls pipe):magnetic particle inspection and magnetic flux leakage inspection are collectively referred to as magnetic flux leakage inspection. physically speaking, they belong to the same detection met

characteristics and application of eddy current flaw detection method for seamless steel pipes:eddy current testing has been used for quality inspection of steel pipes for decades. after continuous improvement and development, eddy current testing has become one of the inspection methods recognized

ultrasonic testing technology for seamless steel pipes:ultrasonic testing refers to the detection of seamless steel pipes using the principle of electromagnetic induction. when using the ultrasonic testing method for detection, it is first necessary to excite a beam of ultrasonic waves inside the se
