Super duplex steel pipe is a high-strength, corrosion-resistant, impact-resistant steel pipe that is often used as a heavy-duty delivery pipe. Below, we will introduce the specification table of super duplex steel pipe in detail.
Super duplex steel pipe is composed of high-strength steel and stainless steel alloy materials. High-strength steel ensures strong and reliable load support, while stainless steel ensures corrosion resistance.
The outer diameter of super duplex steel pipe is generally between 60mm and 426mm, and its wall thickness is generally between 6mm and 40mm. Different pipe diameters and wall thicknesses can meet different delivery requirements.
The standard length of super duplex steel pipe is 6 meters and 12 meters, but according to the needs, it can be customized according to the special requirements of customers. Steel pipes of different lengths can facilitate construction and installation to meet different engineering needs.
Super duplex steel pipes are classified according to different material grades and international standards. Common grades are L245/L290/L360/L415/L485, and standards include ASTM A53/A106/A179/A192/A210/A213/A333/A335, EN10216-1-4, DIN17175-79, etc.
The surface treatment of super duplex steel pipe includes black paint, hot dip galvanized, spray paint, etc. Different surface treatments can increase the corrosion resistance and aesthetics of steel pipes. Most often, steel pipes are hot-dip galvanized to improve their corrosion resistance.
Super duplex steel pipes are widely used in petroleum, natural gas, chemical industry, shipbuilding, construction, machinery manufacturing and other fields. It can not only transport various liquids and gases, but also withstand high pressure over 100MPa.
To sum up, the super duplex steel pipe specification table includes material, outer diameter and wall thickness, length, grade and standard, surface treatment and application. Familiarity with steel pipe specification sheets is essential for proper selection and use of super duplex steel pipe.
