Any questions about our products & services
We offer a comprehensive range of flanges (Weld Neck, Slip-on, Blind, Socket Weld, and Lap Joint) and elbows (Long Radius, Short Radius, 45°, 90°, and 180°). These are available in various material grades, including Stainless Steel, Carbon Steel, and Alloy Steel.
All our products are manufactured in strict accordance with global standards, including ASME/ANSI (B16.5, B16.9), DIN, EN, and API specifications to ensure seamless integration into international projects.
Yes. Every shipment is accompanied by a comprehensive MTC (3.1/3.2). Our products also undergo rigorous quality checks, including PMI testing, ultrasonic testing, and hydro-testing to ensure 100% reliability.
Absolutely. We specialize in "Near-Net" forging and precision machining, allowing us to produce customized flanges and elbows tailored to your specific technical drawings and unique project tolerances.
For standard sizes in stock, we offer immediate dispatch. For customized manufacturing or large-scale project packages, our typical lead time ranges from 10 to 15 days, depending on the material grade and complexity.
Yes. Our components are specifically engineered for the demanding conditions of the Oil & Gas, Petrochemical, and Power industries. We use high-grade materials and heat treatment processes to maximize corrosion resistance and structural integrity.
We maintain a transparent quality process and fully welcome inspections from world-renowned agencies such as TUV, BV, SGS, and Lloyds, as well as client-appointed inspectors.
We understand the cost of downtime. Vianko maintains a strategic inventory of raw forgings and semi-finished components, enabling us to offer Fast Turnaround services for emergency shutdowns and urgent maintenance needs.
