The company specializes in the research and development, production and sales of quenched and tempered GL-E40 hull steel plate seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has quenched and tempered GL-E40 hull steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,quenched and tempered GL-E40 hull steel plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
The company's logistics adopts the method of cooperation with logistics companies. As a third-party logistics company is engaged in the operation of multiple logistics projects, it can integrate various logistics resources, making the logistics operation cost relatively low and the logistics operations more efficient. Thus we can provide more professional logistics services, while also focusing on our core business of steel materials.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the quenched and tempered GL-E40 hull steel plate steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This quenched and tempered GL-E40 hull steel plate method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe quenched and tempered GL-E40 hull steel plate for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. quenched and tempered GL-E40 hull steel plate, 20 # material has low strength, good toughness, plasticity and good weldability.
