Introduction to Quality Control Inspection Methods：

Raw Material Quality Control

MTSCO's pipe raw materials are sourced from reputable steel mills like Baosteel and Tsingshan. To guarantee quality, each batch of raw materials must come with a warranty and PMI (Positive Material Identification) test report. We conduct stringent PMI and other inspections to verify that the materials meet the specified requirements.

In-Production Process Control

MTSCO's seamless pipe production processes encompass cold rolling, cold drawing, annealing, pickling, surface treatment, and more. Each stage utilizes advanced production equipment, overseen by our team of experienced engineers and technicians. Every step is meticulously supervised and documented photographically for archival purposes. We employ process cards to ensure the accuracy and traceability of the entire production process.

Quality Control Prior to Shipment

MTSCO boasts a dedicated QC (Quality Control) team that meticulously inspects and tests each product, covering aspects such as appearance, PMI, dimensions, quantity, and more. We also conduct mechanical testing, hardness testing, ultrasonic testing, eddy current testing, hydraulic testing, and other specialized evaluations. Additionally, we welcome third-party testing from reputable organizations like SGS, TUV, and BV. Prior to shipment, we employ appropriate and secure packaging methods, including container reinforcement, to safeguard the goods against damage during transportation.
