Questions
Common manufacturing, specification, and logistics questions answered directly by our metallurgical engineering team.
We manufacture across all major austenitic, ferritic, and duplex stainless steel grades including 304, 304L, 316, 316L, 321, 310S, 409, and Duplex 2205, compliant with ASTM, ASME, EN, and DIN standards.
Seamless tubes are manufactured by extruding solid billets with no longitudinal seam, offering superior pressure handling for high-stress boiler and hydraulic environments. Welded (ERW) tubes are formed from cold-rolled steel coils with a continuous weld seam, providing excellent dimensional uniformity and cost efficiency.
Yes. Every consignment dispatched from Pinnacle Tube includes a certified Mill Test Certificate in accordance with EN 10204 3.1 detailing chemical composition, mechanical tensile/yield properties, hardness, hydrostatic test pressure, and non-destructive eddy current results.
We cater to both bulk EPC project orders and small-batch specialized requirements. Standard SKUs in 304/316L have flexible MOQs starting from 100 meters, while custom alloy runs are produced to order.
Yes, Pinnacle Tube exports to over 15 countries across the Middle East, Southeast Asia, Europe, and North America with export-worthy wooden sea crate packaging and CIF/FOB shipping terms.
