Its classification society certifications are as follows: China's CCS USA ABS Germany GL France BV Norway DNV Japan NK UK LR Italy RINA South Korea KR (Norway DNV and Germany merged into: VL, nine major classification societies certification. 8. EH420 steel plate flaw detection A and Z direction steel plates should be ultrasonic flaw detection, and the flaw detection grade should be specified in the contract. B. According to the requirements of the buyer, by the agreement of the supply and demand parties, other steel plates can also be inspected non-destructively.

In recent years, emerging developing countries have a large demand for ore, oil and other resources, the international shipping community has accelerated its development, new ship orders continue to increase, China's new ship orders in 2010 reached 130 million deadweight tons. With the continuous increase in new ship orders, the demand for structural steel for ships and offshore engineering has grown rapidly in both quantity and quality. By 2010, the market share of bulk carriers and oil tankers built in China will increase respectively, the market share of container ships will be close to South Korea, and the market share of LNG ships will reach more than 20%, becoming an important producer of high-tech ships.

At that time, shipbuilding steel is expected to reach more than 10 million tons; It is planned to build nearly 80 offshore platforms, which require about 1.6 million tons of high-grade series steel for offshore platforms, of which the pile legs, cantilever beams, and lifting rack mechanisms of self-elevating offshore platforms require 460MPa~690MPa steel grade and 69OMPa or above steel grade of high-strength or extra-thick (thickness up to 259mm) and other special steels
