Product details

The provided image outlines the technical specifications for industrial Pipes & Tubes, which serve as the primary conduits for fluid, gas, and slurry transport across high-pressure, high-temperature, and corrosive industrial processing lines. ## ⚙️ Technical Specifications## Sizing & Production Geometry * Seamless Pipes: 1/4“ NB to 24” NB (Uniform structure without weld seams, optimal for high-pressure loops). * ERW (Electric Resistance Welded): 1/4“ NB to 76” NB (Cost-effective for large-diameter distribution lines). * Structural Profiles: Round, Square, and Rectangular cross-sections. * Wall Thickness Schedules: SCH 5S, SCH 10S, SCH 20S, SCH 40S, SCH 80S, SCH 120S, SCH 160S, and SCH XXS. ------------------------------ ## 📋 Material Specifications & Design Standards## 1. Stainless Steel (Sanitary & Chemical Infrastructure) * Standards: SA 312 (Seamless/welded pipe), SA 213 (Boiler/heat exchanger tube), SA 249 (Welded boiler tube), SA 269 (General service tube), and SA 270 (Sanitary/dairy tubing). * Grades: 304, 304L, 304H, 316, 316L, 316H, 316Ti, 321, 309, 310, 347, 409, 410, 420, 430, and 904L. ## 2. Carbon Steel (High Pressure, Structural & Pipelines) * High-Temperature Service: ASTM A106/A53 Grades B/C, SA 179 (Heat exchangers), SA 192 (Boiler tubes), and SAW & EFw A671 / A672 (Large-diameter fusion-welded pipes). * Cross-Country Line Pipe: API 5L Grades X42, X46, X52, X56, X65, X70, and X80 (Supplied in Product Specification Levels PSL-1 and PSL-2). * Low-Temperature Service: ASTM A333 / A344 Grades 1 to 6 (Formulated for structural integrity in cold climates or cryogenic setups). ## 3. Alloy Steel (Chrome-Moly / Power & Steam Generation) * High-Pressure Piping: ASTM A335 Grades P1, P5, P9, P11, P12, P22, P91, and P92. * Superheater & Boiler Tubing: ASTM A213 Grades T1, T5, T9, T11, T12, T22, T91, and T92 (Available in Welded or ASTM A691 heavy-wall configurations). ## 4. Nickel & Exotic Alloys (Extreme-Service Refining) * Materials: Monel, Inconel, Hastelloy, Pure Nickel, Cupro Nickel, Titanium, Duplex, and Super Duplex. * Selection Metric: Deployed in deep-well offshore drilling, acid production plants, and marine desalination heat exchangers. ------------------------------ If you are detailing an active pipeline schematic, I can look up the outer diameter (OD) and wall dimensions in mm for specific schedules, compare API 5L PSL-1 vs. PSL-2 differences, or locate authorized dealers near Ahmedabad.
