Specified by design engineers worldwide, this 4.0" Nominal Pipe Size (NPS) seamless pipe boasts an outside diameter of 3.275" and a substantial 0.359" wall thickness, adhering to Schedule 160. Constructed from premium 316 stainless steel, it exhibits exceptional resistance to pitting, crevice corrosion, and general corrosion in aggressive media, including chlorides and acids, due to its molybdenum content. The seamless construction ensures uniform wall thickness and eliminates weld-related weaknesses, making it ideal for high-pressure fluid and gas transport in chemical processing, petrochemical, oil and gas, and marine industries.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Verify pipe dimensions and material compliance with project specifications. 2. Clean pipe ends thoroughly, ensuring no debris or contaminants are present. 3. Employ appropriate joining methods (e.g., welding, flanging) according to ASME B31.3 or relevant standards, utilizing compatible filler materials if welding.
