6Mo Pipe/31254 Pipe

6Mo (UNS N08926) pipes and 31254 (UNS S31254) pipes are both super austenitic stainless steels with extremely high corrosion resistance. They contain high proportions of molybdenum (Mo), chromium (Cr) and nitrogen (N), and can provide excellent resistance to pitting, crevice corrosion and stress corrosion cracking in high chloride ion concentrations and strong oxidizing media. Both materials have good mechanical strength and excellent welding properties, suitable for long-term use in extreme environments.

 In terms of application, 6Mo and 31254 pipes are widely used in marine engineering, seawater desalination, chemical equipment, pulp and paper industry and other fields that require extremely high material corrosion resistance. They are especially suitable for key parts such as heat exchangers, pressure vessels, condensers, and piping systems, which can effectively extend the service life of equipment and reduce maintenance costs. Both are often regarded as economical alternatives to nickel-based alloys and titanium.

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.
