下周唐山方管价格或将呈弱势调整方管厂家降…方管周初开市，期螺低开，全天低位运行，方管市场成交差，市场情绪普遍低落，方管厂家降价销售，。周中期，随着中美磋商的进行，期螺强势翻红，市场信心受到提 振，不过在午后传出中美磋商“不欢而散”的消息后，期货毫不犹豫的再次走低美联储降息，股市、期货全部泛绿，市场悲观气氛骤增。周后期，特朗普再放对中…

方管市场价格稳中有跌。 昨日黑色系螺纹钢主力合约拉升，市场心态提振。今日部分方管厂家价格出现小幅上抬，昨天接单有所放量。但就今日的期货来讲整体现货市场并未尽如人 意，再次回落。方管厂家方面暂时没有出现价格调整，前几日的下调幅度在50-100元不等，其中219-273近期下调幅度大。厂家新生产线增加，大口径管竞 争上升开始冲击市场，方管厂家昨日出货有所放量，消化库存为主。方管市场方面，市价处于滞后性下跌，多为稳中盘整，市场出货好些有限，现阶段方管从涨跌中获取利 益可能性较低，主要看需求量，保证利润出货，灵活操作，随出随补。预计短期国内方管市价弱势运行。

The price of the market has fallen steadily. Yesterday, the main contract of black thread steel was lifted, and the market mentality was boosted. Today, the prices of some Square managers have risen slightly. Yesterday, orders were received in a large amount. But for today's futures, the overall spot market is not as good as expected, and it has fallen again. There has been no price adjustment for the manufacturers under the control of the party. The range of price reduction in the past few days ranged from 50 to 100 yuan, of which 219-273 has been greatly reduced recently. With the increase of new production lines, competition for large caliber pipes has begun to hit the market. Square pipe manufacturers released some goods yesterday, mainly digesting inventory. On the market side, the market price is in a lagging decline, mostly in a stable consolidation, market shipments are limited. At this stage, the possibility of obtaining benefits from the rise and fall is low, mainly depending on the demand, ensuring profit shipment, flexible operation and follow-up. It is expected that the domestic market price will be weak in the short run.

厂家防止方管坯分层的三点措施方管有时方管坯会出现分层问题，从而导致探伤不合。要预防这一缺陷，我们可以采取以下三点处理措施：(一)优化缓冷时间：优化方管板坯的缓冷工艺，主要针对堆垛温度和堆垛持续时间。轧制钢板厚度不大于80mm钢板热矫直后，在冷床停留时间不得超过5min。厚度大于80mm钢板可适当延长至10min，确保钢板成垛前温度控制在500℃以上。钢板… 方管市场价格震荡调整成交方面尚可方管方管市场价格震荡调整。主导市场，北京、天津均涨跌不一，上海、广州均小幅上涨。节后开市，继轻仓过节，盘面又开始活跃起来，早盘虽 在低位，但有小幅反弹，钢坯也小涨10元，市场方向并不明确，涨跌都有。不过午后在空头压制下，盘面不断下行，部分地区的价格随之出现松动。不过从市场了 解到，今日成交方面尚可，北京节后工…
