ASME SA312 TP304/TP304L Stainless Steel Seamless Pipe for High Temperature Service
ASME SA312 TP304 and TP304L stainless steel seamless pipes are ideal for high-temperature service.
TP304, with its UNS S30400 designation, has good oxidation resistance at elevated temperatures, often used in industrial furnaces. TP304L (UNS S30403) offers better weldability and corrosion resistance in high-temp, corrosive environments like petrochemical heaters.
Both pipes ensure structural integrity and durability under high-temperature conditions, playing a crucial role in applications such as power plant boilers, where they transport high - temp fluids stably contributing to reliable operation in harsh thermal environments.
