随着海洋开发事业的迅猛发展,目前世界上许多国家正在不断兴建各种海洋构筑物,如海底石油和天然气钻探及采油采气装置、海底管线、大型油船、系泊设施、海港码头、钢管桩栈桥和深海潜艇等,大量使用海洋结构钢。而且,今后在海底贮罐、海底隧道、人工岛、大型钢桥、海上机场及海水淡化装置等方面钢材使用量也将急剧增长,对海洋开发设备用钢提
With the rapid development of marine development, many countries in the world are constantly building various marine structures such as submarine oil and gas drilling and production equipment, submarine pipelines, large oil tankers, mooring facilities, harbor terminals, steel pipe piles Trestle and deep sea submarines, extensive use of marine structural steel. In the future, the use of steel products in seabed storage tanks, undersea tunnels, artificial islands, large steel bridges, marine airports and seawater desalination plants will also increase sharply. Steel for the development of marine equipment
