The advantages of S690QL equivalent indian standard, steel plate produced from coil: price is cheap and length can be freely determined; transportation is convenient, no need to consider according to the size of steel plate; cutting is convenient, according to the actual needs of steel plate size cutting, and finally can effectively save materials. The disadvantage of steel plate produced from coil: there will be great welding deformation during welding, which is difficult to adjust. Therefore, the steel plate produced from coil can not be used for parts with high requirements on appearance quality.

The riser is an indispensable equipment in the development of offshore oil and gas resources, mainly for drilling, conducting liquid, conducting mud and transporting oil and gas. Because steel catenary risers face complex service conditions such as surges, seabed clay, and ice loads, they need to have high fatigue strength, large plastic deformation capacity, and excellent fracture toughness. At present, China's first self-developed and designed 6-inch steel catenary riser was successfully laid on August 18 this year in the first deep-water self-operated large gas field Lingshui 17-2 project.
