At present, we have 3 sets of hot-rolled seamless steel pipe production lines with an annual production capacity of 1.35 million tons. The physical and chemical laboratory conducts various physical and chemical tests on steel pipes, and is equipped with eddy current flaw detectors, magnetic flux leakage detectors and ultrasonic flaw detectors. It is used for high, medium and low pressure seamless steel pipes and oil casings. All-round inspection measures can meet various standard test and inspection requirements for steel pipes.
