Inspection and testing equipment

The entire production line is equipped with advanced and complete online testing, control, sampling, sample preparation and testing equipment. The test data is transmitted by the computer system to the relevant production units for production control to meet the quality requirements of users for high-end products.

The hot rolling line is equipped with online piece-by-piece length measuring and weighing devices, tube-by-piece temperature measuring instrument, capillary outer diameter, length, temperature measurement system, capillary temperature measurement before continuous rolling, continuous rolling mill automatic detection of rolling force, roll gap Large and small system, the full length of the steel pipe wall thickness measurement, diameter measurement, temperature measurement and length measurement system after the pipe stripping machine, the temperature measurement system before and after the sizing, the diameter measurement and length measurement system after the sizing. These inspection systems ensure the product quality of each steel pipe's wall thickness accuracy and outer diameter accuracy.

The steel pipe heat treatment and finishing line is equipped with magnetic flux leakage flaw detector, ultrasonic flaw detector, pipe end magnetic particle flaw detector, online hardness testing machine, etc. The key quality inspection equipment is imported from abroad, which can detect various quality defects such as vertical and horizontal steel pipes and delamination.

The inspection and testing equipment can meet the requirements of API 5CT/5L, ASTM, DIN, GB and other standards for sample processing and inspection of hot-rolled seamless steel pipes.
