The better weldability also makes 4130 Carbon Steel Pipe a popular choice in the aerospace industry, which is used to manufacture commercial and military aircraft components requiring high strength and low weight. Examples include gears, piston pins, etc. Other uses of 4130 steel include auto parts, cutting tools and drilling machines.
A214 carbon steel pipe: resistance welded carbon steel pipe for heat exchanger and condenser.
Application: It is suitable for stress and pressure parts, as well as steam, water, gas and air pipelines for general purposes. A53 pipeline pipe belongs to American petroleum standard pipeline pipe. Pipeline pipe is used to transport oil, steam and water pumped out of the ground to oil and natural gas industrial enterprises through pipeline pipe. Pipeline pipe includes seamless pipe and welded steel pipe, with flat end, threaded end and socket end at the pipe end; The connection methods are end welding, coupling connection, socket connection, etc.
The advantages of cast iron electrode Ni55 Suitable for repairing and welding gray cast iron, high-strength ductile iron, such as cylinders, engine supports, gears, rollers, etc. Its advantages are high strength, good plasticity, low coefficient of linear expansion, etc. The crack resistance of gray cast iron is similar to that of Z308, but the crack resistance of ductile iron is higher than that of Z308.
