31日國內焊管價格下調意愿仍不強。今午前期螺盤面維持低迷震蕩為后市選擇方向蓄力，上游145mm系列窄帶整體追降30，而焊管出廠價格 政策下調意愿仍不強，部分跟調20-30，目前河北地區主流管廠焊管4寸(3.75mm)出廠報價在4490-4610元之間，管廠交投清淡。市場方面， 華東、華南地區今日焊管價格部分出現回落20-30，鍍鋅管價格因管廠價格表結構調整仍有陸續下跌。綜合來看，近日公布的唐山限產政策未達預期，加之臨月 底結算市場需求拖累，堅挺格局或難以維持。預計明日國內焊管價格走弱。31, the domestic steel pipe price reduction intention is still not strong. In the early afternoon, the spiral disk surface remained depressed, and the upper 145mm narrow band fell by 30 as a whole. However, the willingness to lower the ex-factory price policy of welded pipes is still not strong. Some of the welded pipes are adjusted by 20-30. At present, the ex-factory price of 4 inches (3.75mm) welded pipes in Hebei mainstream pipe factories is between 4490-4610 yuan, and the delivery of the pipes is light. On the market side, the price of welded pipes in East and South China dropped by 20-30 today, and the price of galvanized pipes continued to fall due to the adjustment of price list structure. Overall, the recently announced policy of limiting production in Tangshan has not met expectations, coupled with the end of the month settlement market demand drag, a strong pattern or difficult to maintain. It is estimated that the price of welded pipe will weaken in China tomorrow.價格方面：國內重點城市4寸(3.75mm)焊管的平均價格為4683元，較昨日降1 元，其中中心城市主流價格北京降20元，其他暫穩。Price: The average price of 4 inch (3.75 mm) welded pipe in key cities in China is 4683 yuan, which is 1 yuan lower than that of yesterday. The mainstream price in central cities is 20 yuan lower than that in Beijing. Other prices are stable temporarily. 方管
