 　　The overall coal price is stable and declining, mainly because the traders and the downstream have the expectation of increasing production after Daqing. In addition, the concentration of imported coal to Hong Kong reduces the psychological pressure, increases the base gas, reduces the coal purchase in the market, and observes the increase of production and the change of coal price after Daqing. Considering the market's expectation of increasing production, as well as the fear of price and the worry about the later policy, most traders dare not continue to purchase and ship. There are also consignors who store coal in the early stage, in order to deal with the later variables, take the initiative to reduce the sales price, leading to a drop in the port price. 　　Since last week, the inventory of Beigang has gone through a week of rapid destocking.

 　　What are the weld requirements for straight seam steel pipes? 　　1. The height of the weld burr of the electric resistance welded steel pipe (ERW pipe) 　　The external burrs of the steel pipe welds should be removed, and the remaining height should not be greater than 0.5mm. 　　According to the request of the buyer, after negotiation between the supplier and the buyer, and specified in the contract, the burrs in the weld of the steel pipe can be removed. After the internal burr of the weld is removed, the remaining height should not be greater than 1.5mm; when the wall thickness is not greater than 4mm, the depth of the scraping groove after removing the internal burr should not be greater than 0.2mm; when the wall thickness is greater than 4mm, the depth of the scraping groove should not be greater than 0.4mm. 　　2.

 　　Cold rolling and Hot rolling are forming steel or steel plates, and they have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is only used for the production of small section steel and sheet. 　　The main difference between hot rolled and cold rolled seamless steel tubes: 　　1. Cold-rolled formed steel allows local buckling of the section, so that the bearing capacity of the member after buckling can be fully utilized;hot-rolled steel does not allow local buckling of the section. 　　2. The causes of residual stress in hot-rolled steel and cold-rolled steel are different,so the distribution on the cross section is also very different. The residual stress distribution on the cross section of cold-formed thin-walled steel is curved, while the residual stress distribution on the section of hot-rolled or welded steel is thin film. 　　3. The torsional stiffness of hot-rolled steel is higher than that of cold-rolled st...
