本周自周一黑色系期螺突然跳水后，整体走势趋弱几次跳水。主要是上周的上涨，现货的成交明显跟不上期货的节奏支撑不够。消息面，脱欧还在半空中， 梅姨辞职；铁矿石、焦炭疯长，中美贸易战不断加剧。管坯近日再次走弱，临沂管厂也出现小幅下调。市场方面，近三个月沧州方管成交量处于递减状态，本地方管市场交投氛围清淡，方管市场价格价格弱稳。通过贸易商了解到，市场需求递减，较往年同期出货量下降很多，库存释放缓慢，总体情况不佳，商家对方管后市不 看好，多暗降出货，保证利润。库存相对较低。由于高温天气及雨季即将到来，采购量明显减少，大都按需采购，而下游基本以各厂资源比价买货，综上所述，预计 下周沧州方管市价震荡偏弱依然趋弱。原料面，截至5月31日，唐山昌黎部分普碳方坯含税出厂3560元(吨价，下同)较上周同期跌30元。

News, leaving Europe is still in the air, Aunt Mei resigned; iron ore and coke are growing rapidly, and the Sino-US trade war is intensifying. Pipe billet weakened again recently, Linyi Pipe Factory also showed a slight decline. On the market side, the volume of Cangzhou Square Tube has been declining in the past three months. The local seamless tube market has a light trading atmosphere and the price of Square Tube market is weak and stable. Traders know that the market demand is declining, compared with the same period in previous years, the volume of shipments has dropped a lot, inventory release is slow, the overall situation is not good, the merchants are not optimistic about the market after each other's management, how secretly to reduce shipments, to ensure profits. Inventory is relatively low. As the hot weather and rainy season are approaching, the purchasing volume is obviously reduced, most of them are purchased on demand, while the downstream is basically purchased at the price of resources of each factory.

Raw materials, as of May 31, Tangshan Changli part of the carbon billet with tax factory 3560 yuan (ton price, the same below) fell 30 yuan from the same period last week.
