    電站鍋爐用高等級耐熱鋼管指定進口的適宜性探討

    Discussion on Suitability for Designated Import of Hi-grade Heat-resistant Steel Pipes/Tubes for Power Plant Boiler Service

    • 摘要: 針對國內電站鍋爐合同技術協(xié)議中“高等級耐熱鋼須進口”限制性條款，分析國內外高等級耐熱鋼管制造現(xiàn)狀、實物質量、標準差異及供貨商的技術反饋，探討制定進口高等級耐熱鋼的適宜性。分析認為：國產高等級耐熱鋼管（國產92級、S30432、TP310HCbN）已達到進口鋼管質量水平，且在采購周期、技術響應和服務、成本等方面更具綜合優(yōu)勢。建議在電站鍋爐合同技術協(xié)議中取消“高等級耐熱鋼須進口”的條款。

       

      Abstract: Addressing the proviso as under relevant domestic contractual technical agreements for power plant boilers which says that hi-grade heat-resistant steels as used must be imported,the main aspects concerning heat-resistant steel pipes/tubes as made at home and abroad are analyzed,including the present manufacture situations,the actual pipes/tubes quality,the standard differences and the technical feedbacks from the supplier, etc.Accordingly, it is discussed how to determine the suitability for import of the hi-grade heat-resistant steel pipes/tubes.The analysis leads to such a conclusion that the domestically-made hi-grade heat-resistant pipes/tubes(e.g.the Gr.92,S30432 and TP310HCbN pipes/tubes) have been up to the quality level of those as imported,and have been more comprehensively advantageous in terms of purchase cycles,technical response and service,and cost,etc.Therefore it is suggested the above mentioned proviso be removed from the said technical agreement.
