方管市场价格主稳个调。今晨受夜盘期货下跌运行的影响，今日开市，国内方管市场主流价格部分下调，但盘中随着期货震荡走高，钢坯涨20元，市场需求有所回暖。刺激了一定 的需求，出货有所上升。北方地区方管价格波动不大，其代表城市唐山地区价格盘中部分上涨10元，但由于停产执行期间，部分规格库存下降较为明显，所以钢厂 价格适当调整，由于午后需求相对转强，整体北方市场出货尚可。南方地区方管市场近期出货一般，商家心态谨慎，因为北方方管钢厂出厂价格在坚挺中略微松动， 所以报价先持稳后续跟涨期货小幅度上调，据了解各个地区需求不强，所以上涨吃力，库存相对齐全，个别缺货规格陆续补货，但在高成本的情况下，价格难以明显 下跌，部分方管厂家对后市仍是悲观心态。午后钢坯涨20元，现普碳方坯含税出厂3640元，预计明日国内方管市场价格窄幅调整。

The market price should be adjusted steadily. Affected by the falling operation of the night futures market this morning, the main price of the domestic market was partly lowered when the market opened today. However, with the rising volatility of the futures market, the steel billet rose by 20 yuan, and the market demand warmed up somewhat. Stimulated a certain demand, shipments have increased. The price fluctuation in the northern area is not very large, which represents a 10 yuan rise in the price plate of Tangshan city. However, due to the obvious decline in some specifications during the period of shutdown, the price of steel mills is adjusted appropriately. Due to the relative stronger demand in the afternoon, the shipment of the whole northern market is still possible. Southern area square pipe market recently shipment is general, business mindset is cautious, because the northern pipe steel factory factory factory ex-factory price is slightly loose in the firm, so the quotation is stable first followed by a small increase in futures, according to the understanding that the demand in each region is not strong, so it is difficult to rise, inventory is relatively complete, and individual shortage specifications are replenished one after another. However, in the case of high costs, prices are difficult to fall significantly, and some managers are still pessimistic about the future market. In the afternoon, the steel billet rose by 20 yuan, and now the ordinary carbon billet is out of the factory with tax of 3640 yuan. It is expected that the price of domestic square pipe market will be narrowly adjusted tomorrow.
