In April 2018, our Philiphine customer purchased 1008 Tons API5L Gr.B ERW&Q345B SMLS pipe for offshore oil field 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.
Chromium element (Cr element) can improve the strength and hardness of S690QL steel welding, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
The company's main steel plates have twelve types of steel products like boilers and pressure vessels, low-alloy high-strength steel S690QL steel welding, wear-resistant steel plates, corrosion-resistant steel plates, high-rise building structural steel plates, marine structural steel plates, alloy structural steel plates, mold steel plates, carbon structural steel plates, shipbuilding and steel plates for oil production platforms, composite steel plates, steel plates for oil and gas pipelines. We offer various steel grades, and more than 300 kinds of thickness specifications.
Rizhao Steel 5#ESP Headless Strip Production Line Project is a key construction project in Shandong Province. It is also the fifth domestic ESP production line introduced by Rizhao Steel and the sixth ESP production line in the world. Its thinnest design is 0.5mm, which is at the world's leading level. The more than 20 important nodes set by the entire project have been basically completed, and the equipment has entered the commissioning stage. It is expected to be put into operation at the end of November.
