The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length A572 grade 55 CS steel carbon plate is suitable for the length required by the construction of steel pipes.
The company attaches great importance to systematic management, and has passed the A572 grade 55 CS steel carbon plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A572 grade 55 CS steel carbon plate quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
Today, the prices of black commodity futures market fluctuated upward. The mentality of the spot market is optimistic, and the quotations of A572 grade 55 CS steel carbon plate merchants continue to rise. However, downstream users are more cautious in purchasing, and they basically purchase on demand. Some speculative demands have the willingness to replenish at low prices. At present, there are relatively few A572 grade 55 CS steel carbon plate inventory resources in the market. In addition, the cost of resources in the later stage is relatively high, so businesses are not willing to sell at low prices. On the whole, there are not many short-term new arrival resources, and the shipping pressure of merchants is not big, and the A572 grade 55 CS steel carbon plate price still has certain support. It is expected that the price of A572 grade 55 CS steel carbon plate will fluctuate and be stronger tomorrow.
