ASTM A376 / ASME SA376 TP347H Stainless Steel Seamless Pipe For Petrochemical Industry
ASTM A376 / ASME SA376 TP347H pipes are manufactured through a seamless process (extrusion or rotary piercing), ensuring a uniform structure and superior pressure-bearing capacity without a welded seam. This grade was developed specifically for prolonged exposure to the creep range (temperatures between 427°C to 899°C). It is widely used in the power generation and petrochemical industries where oxidation resistance and high-temperature strength are critical. YUHONG GROUP has produced stainless steel seamless pipes for 35 years with high quality and competitive prices. Our pipes have been sold to 85 countries worldwide until now. If you’re interested in our stainless steel seamless pipes, welcome to contact us for details.
