With the increase of production restriction of steel enterprises and the pressure of demand, the continuous decline of iron ore port inventory may end. In addition, according to the new statistics of * *, the available days of imported iron ore of steel mills are days, which is one day lower than that before the National Day, and is on the high side of history. The steel mill said that at present, the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction,Mataro 20CrNiMo alloy steel plate, the steel mill is not willing to replenish the inventory.Penza,Extrusion method: This production method is to cast copper ingots after smelting, and extrude copper tubes by large extruder after secondary heating.The ex factory price of Linyi Pipe Factory has decreased by yuan for cash Baocheng ( * mm, the same below) yuan, yuan for Ruigang Lianlian, yuan for Baoda yuan, yuan for Meixin yuan, and yuan for Taizong yuan.In view of the current overall price difference, while the regions outside East China did not show an obvious follow-up trend, and the local price still has the advantage of price difference with the Northeast and Central China regions.

Insert the pipe into the top of the bayonet, and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux, and the joint is assembled and can be heated.Methods of copper pipe anti-corrosion Strengthen scientific research.The copper tube shall be heated and welded first, and then the joint shall be heated until the heated part turns dark red. At this time, when the filler metal contacts the tube, the filler metal shall melt.Honesty and mutual benefit,The blowing mouth of the welding tool should not be too small to avoid excessive concentration of heat.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.In the first ten days of May, the overall order receiving quantity of Tianjin Hebei Henan Plate Plant was not ideal. According to the monitoring data, the overall order intake of medium and heavy plate mills in Tianjin Hebei Henan region in the first ten days of May remained stable and weak.

The total quantity of orders received in the first ten days of May is only about tons, while at the end of April, the total quantity of post settlement agreements of main steel plants can exceed tons.

Advantages: good quality, fine structure, high density, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange, and large size copper tube can be produced.Quality inspection reportInsert the pipe into the top of the bayonet,e the sleeve on the pipe to evenly apply the flux on the joint, and confirm that the pipe is inserted into the bottom of the socket, then wipe off the excess flux, and the joint is assembled and can be heated.In order to solve these problems, silicon containing welding wires are commonly used in welding, because silicon will form a layer of dense silicon film on the surface of the molten pool, which will hinder the evaporation of zinc and prevent the invasion of hydrogen.The market opened today. Although the performance of Zitong Pai futures was modest, the overall market has stopped. The market mentality has not changed much sincekend.
