Made by YOUFASS Stainless Steel Pipe Co., Ltd., a Top 500 endeavor in China, our super duplex channeling arrangements combine progressed EFW innovation with arrangement strengthening and water extinguishing. With 15 committed generation lines and an yearly yield capacity of 50,000 tons, we supply large-diameter channels extending from 114.3 mm to 2500 mm OD with divider thickness up to 50 mm. Supported by ISO9001, PED, ISO 17025 lab accreditation, and TÜV certification, each pipe comes with total traceability documentation counting MTC 3.1/3.2, WPS/PQR, and UT/RT reports.
What Makes Duplex 2507 EFW Pipe Different?
Super Duplex 2507 (UNS S32750) stands out in challenging situations. Its adjusted austenite-ferrite microstructure gives you twice the quality of standard austenitic stainless steels. You get exceptional resistance to setting, cleft erosion, and stretch erosion cracking—especially in chloride-rich conditions.
The Electric Combination Welding prepare makes reliable, high-integrity welds over expansive breadths. This fabricating strategy permits us to create channels up to 2500 mm OD that keep up uniform mechanical properties throughout.
After welding, each ASTM A928 Electric Fusion Welded Duplex 2507 Pipe undergoes arrangement tempering taken after by quick water extinguishing. This warm treatment optimizes the microstructure and reestablishes erosion resistance in the weld zone.

Frequently Asked Questions
Q:What is Duplex 2507 EFW pipe?
A:It's a super duplex stainless steel pipe fabricated utilizing electric combination welding innovation. The 2507 review offers predominant erosion resistance compared to standard duplex 2205, making it perfect for the most forceful environments.
Q:Why should I choose 2507 over other stainless steel grades?
A:You get prevalent erosion resistance and tall quality in one fabric. The PREN (Pitting Resistance Equivalent Number) surpasses 40, giving amazing resistance to localized erosion. You can utilize more slender dividers compared to austenitic stainless steels, diminishing fabric costs and weight.
Q:What are the primary applications for these pipes?
A:Oil & gas generation and preparing, petrochemical plants, seawater frameworks counting desalination, seaward stages, subsea pipelines, and any application including chloride presentation, lifted temperatures, or tall pressure.
Q:Can you supply pipes with beveled ends ready for welding?
A:Yes. We offer both plain conclusion and beveled conclusion wraps up. Beveling points can be customized to coordinate your welding strategies and specifications.
Q:What documentation do you provide with the pipes?
A:Every shipment incorporates Material Test Reports (MTR) per EN 10204 3.1 or 3.2, fabricating prepare determinations, ultrasonic and radiographic testing reports, and welding strategy documentation. Third-party assessment reports are accessible upon request.
