包头方管市场价格震荡调整，本周包头方管市场上行为主。在大环境宏观经济调控的背景下，本地区方管市场自我调节中，缓慢恢复生态平衡，上周末市场涨价心态萎靡。本周市场有明 显回暖，周初开市，因期螺持续上涨，钢坯紧跟其后，所以包头等周边外围方管市场价格上涨明显，但是采购欲望不强，高位成交受限，市场看空，部分商户并未跟 涨。市场状态萎靡，周中期，期螺高位波动持稳运行，钢坯小幅上涨，成本有一定支撑。市场温度上升成交转好，但是根据市场部分钢厂资源货少价格偏高，市场价 格有一定紊乱性。在本地大钢厂价格引导下趋于稳定，周后期，市场报价小幅调整，期螺钢坯趋稳，成交尚可，本周库存消耗明显，包头方管市场库存总量 25.44万吨，环比上周降3.03%，同比去年涨12.91%。本周包头方管市场价格盘整下行，整体出货有所好转，价格累涨后窄幅盘整。

Baotou is responsible for the adjustment of market price shocks, and this week Baotou is responsible for market actors. Under the background of macro-economic regulation and control in the macro-environment, the local government has slowly restored the ecological balance in the self-regulation of the market, and the market price-raising mentality was depressed last weekend. The market has obviously recovered this week, opening at the beginning of the week, due to the continuous rise of snails and steel billets, so the prices of peripheral square tube markets such as Baotou have increased significantly, but the desire for purchasing is not strong, high transaction is limited, the market is bearish, and some merchants have not followed up. The market is in a sluggish state. In the mid-week period, the fluctuation of snail heights keeps stable, the billet rises slightly, and the cost has some support. Market temperature rises and turnover turns well, but according to the market part of steel mills, the price of resources and goods is on the high side, and the market price is somewhat disordered. At the end of the week, the market quotation was adjusted slightly, the billet of futures was stable, and the turnover was still acceptable. This week, the stock consumption was obvious. The total stock of Baotou square pipe market was 254,400 tons, which was 3.03% lower than last week and 12.91% higher than last year. This week, Baotou took charge of the market price consolidation downward, the overall shipment improved, after the price increased, narrow consolidation.

综合来看，本周包头方管市场价格拉涨后趋于稳定，受期货利好影响，采购先观望后紧跟，目前看供给大幅走弱的可能性非常低，而中美贸易持续来看充满未知性，因此，预计下周包头方管市场价格将维稳或窄幅盘整。

Generally speaking, Baotou's market price tends to be stable after rising this week. Affected by the good futures market, purchasing follows closely after watching. At present, the possibility of a substantial weakening of supply is very low. China-US trade continues to be full of unknown. Therefore, it is expected that Baotou's market price will remain stable or narrow consolidation next week.
