The types of steel plates are usually divided into three types: lr/DH36 ship building steel plate thick plates (above 6mm), medium-thick plates (3-6mm) and thin plates (below 3mm) according to their thickness. In terms of plate-making process, low-carbon steel plates can be divided into two types: cold-rolled and hot-rolled. Hot rolling alone can produce low-carbon steel plates of about 1.2mm and stainless steel plates of about 2mm. Thinner lr/dh36 ship building steel plate plates can be manufactured by cold rolling, annealing and tempering rolling.
The selection of the proper type of offshore structure is discussed from a technical and economic point of view. The design procedure for the fixed offshore structure lr/dh36 ship building steel plate will be presented and how to review the design to reach the optimum solution.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the lr/dh36 ship building steel plate construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU lr/dh36 ship building steel plate steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.
