Product Introduction

ASME SA335 P91 boiler steel pipe has good mechanical properties, high temperature resistance, corrosion resistance and creep resistance, which can guarantee the stable operation of the equipment under relatively harsh working environment. However, the welding performance of ASME SA335 P91 boiler steel pipe is poor and the process requirements are difficult.
