5800 tons 08cupvre plate ERW pipe for Qatar Integrated Railway Project

The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of 08CUPVRE plate cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.

In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the 08CUPVRE plate and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than 08CUPVRE plate 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.
