Simple Description: Pipe spools for CCPP under dispatching. Main-Steam and Hot-reheat pipelines in comply with the material codes SA335 P91&A234WP91 in order to withstand the max temperature up to 580℃。 Cold-reheat pipelines adopt the material of SA335 P11/P22&A234 P11/P22 to endure the medium temperature and pressures。 WB36 is the best material option for Water-feeding pipeline with the application to bear the highest pressure(36Mpa). Another signature project of 2*660MW Super-critical Power Plant witness our capacity and achievements. Integral piping material package delivery (Pipes+Fittings+Bends+Flanges/Forging=Pipe Spools)， catering for the critical pipeline applications of CCPP,HRSG and Boiler. State of Art craftsmanship along with the numerous know-how and experience to conceptualize the very notion " Diligence，Exact，reliability". Our Service：
