Quality Control of MTSCO Seamless Pipe:
1. Quality Control of Raw Materials
MTSCO pipe raw materials come from large steel mill such as Baosteel and Tsingshan. Each batch of raw materials requires a warranty and PMI to ensure the quality. We will conduct PMI and other inspections to ensure that they meet the material requirements
2. Process Control During Production
MTSCO seamless pipe production processes include cold rolling, cold drawing, annealing, pickling, surface treatment, etc. Each process is equipped with advanced production equipment, and we have experienced engineers and technicians. Each link is supervised by them and photographed for archiving. We use process cards to ensure the accuracy and traceability of the entire production process.
3. Quality Control Before Shipment
MTSCO have a professional QC team that conducts a series of inspections and experiments on products, including appearance, PMI, size, quantity, and other inspections. At the same time, we also conduct mechanical, hardness, ultrasonic testing, eddy current testing, hydraulic testing, and other tests. In addition, we also accept third-party testin, such as SGS, TUV, and BV. Before shipping, we use appropriate and safe packaging methods and take measures such as container reinforcement to ensure that the goods are not damaged during transportation.
