Product Description

Xi 'An QinSteel Trading Co., Ltd | Premium A312 TP304L Pipe Stainless Steel

When you need reliable piping solutions for harsh environments, A312 TP304L pipes deliver unmatched performance. Designed to meet ASTM/ASME standards, these pipes combine superior corrosion resistance with high-temperature stability, making them ideal for oil & gas, chemical processing, and power generation applications. With a carbon content below 0.03%, A312 TP304L prevents carbide precipitation, ensuring durability even in welded structures exposed to corrosive media.

Product Overview

The products are available in seamless (for high-purity systems) or welded (cost-effective) constructions. Their low-carbon 304L stainless steel composition resists pitting, crevice corrosion, and stress corrosion cracking, even in chloride-rich or acidic conditions.
