Technical Specifications

Why Cold Rolled Duplex Steel Pipes

Cold rolling is pivotal to achieving high-precision duplex stainless steel pipes. MTSCO employs cold rolling mills for high-deformation processing, significantly enhancing wall thickness tolerance accuracy and surface finish. This process, combined with precise solution annealing, eliminates residual stresses and refines grain structure. This process ensures our seamless duplex stainless steel tubes are directly applicable in precision instruments, gauges, and heat exchange systems demanding extreme airtightness and uniform wall thickness.

How Do We Guarantee Absolute Quality?

· Raw Material Admission System: Sourced exclusively from major steel mills like Baosteel and TSINGSHAN. Each batch must include original MTC and undergo secondary PMI test by MTSCO prior to warehousing.

· Full Process Digital Tracking: Production process cards (Process Cards) record parameters, operator details, and environmental data for each operation, ensuring product traceability.

· 100% Pre-Shipment Inspection: Beyond routine visual, dimensional, and quantity checks, we employ ultrasonic (UT) and eddy current (ET) flaw detection to guarantee zero defects in the pipe body. Mechanical properties and hardness tests further validate material compliance.
