Chiho Hebei steel pipe diameter pipe industry is the most widely used of a class-diameter pipe. Material which can be divided into low-carbon steel diameter pipe, carbon steel reducer pipe. Low-carbon steel-diameter pipe can be divided into ordinary low-carbon steel, high-quality low-carbon steel, low carbon steel boiler and low-carbon steel container. Since the carbon content of such diameter pipe diameter low-alloy pipe manufacturers, good weldability, high alloy pipe diameter, usually without the use of special process steps, you can get high-quality welded joints. Moreover alloy diameter pipe sales, low-carbon steel reducer plastic, small hardening tendency, near the weld seam zone is not easy to cold cracking. Generally does not require preheating before welding, but for large thickness or welding at a low temperature environment, you need to be preheated to about 150 ℃. Since the material in steel-diameter pipe increased carbon content, and therefore low-carbon steel welding performance compared reducers difference.
