High quality pipeline steel plate is the key material for ERW line pipe, LSAW line pipe and A709 Gr 50 structural steel sheet SSAW line pipe. It is widely used in oil, natural gas and water transportation pipeline construction, and can be used for manufacturing pressure fluid transportation construction.
Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the A709 Gr 50 structural steel sheet alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the A709 Gr 50 structural steel sheet wear-resistant property to meet the requirements of specific working conditions.
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the A709 Gr 50 structural steel sheet rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of A709 Gr 50 structural steel sheet steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
