Steel pipe to do water pressure, bending, flattening and other experiments, there are certain requirements for surface quality, usually delivery length is 12 meters, often requiring a standard delivery. Spiral steel pipe specifications are expressed in nominal caliber (mm), nominal caliber is different from the actual, according to the regulations wall thickness there are ordinary steel pipe and thickened steel pipe types. Thick wall large diameter spiral steel pipe is made of steel coil plate as raw material, often hot extrusion molding, to automatic double wire double side buried arc welding process welded by spiral seam steel pipe.
