周末至今，國內焊管價格再現普漲。周末，隨著唐山地區環保限產政策的再次升級，由現有的部分燜爐限產全部提高到凡減產必停爐，不得以燜代停，受此消息帶動，鋼市價格被不斷推高。焊管方面，受成本端的有力支撐，現河北地區主流管廠焊管4寸(3.75mm)出廠報價在4390-4550元之間，比上 周五上漲30-60元不等，目前管廠倒掛情況有所好轉，但由于價格處于高位，整體成交一般。下游市場，周初開市大部分地區大幅跟漲，但據貿易商反饋出貨不暢，市場恐高情緒較濃。短期來看，因環保限產帶來的炒作空間依然存在，原料價格堅挺將繼續影響國內焊管價格高位運行，但整體操作更趨謹慎。Up to the end of the weekend, the price of domestic welded pipe has increased.
