Development and Production of 33 mm Thickness Specification X80M Pipeline Steel Plate
GUO Chaohai
Abstract：According to the demand of steel pipe for the third West-East Gas Pipeline of CNPC, the X80M steel plate with thickness of 33 mm for making theΦ1 219 mm pipes was developed by the Iron and Steel Institute of Shandong Iron and Steel group. Through the design of composition, microstructure and production process, using a variety of techniques, the 1 000 tons of trial production was carried out by the excellent equipments in Shandong Iron and Steel Group. The properties of the products was very excellent, and can fully met the design requirements, and they have low yield ratio and high crack arrest toughness. The performance of steel pipe made by steel plates can fully meet the requirements of Standard according to the inspection by domestic authorities departments. Base on this industrial trial production, Shandong Iron and steel group entirely have the ability of mass manufacturing ofΦ1 219 mm×33 mm X80M steel plate for main line steel pipe.
