 as we have a process of welding when manufacturing, the surfaces of steel pipe may be not flat which can not meet the construction industry standards. In order to produce practical products, flattening weld joint applied to round steel pipes and square steel pipes is crucial to the overall manufacturing process. Our small steel pipes can be inserted in large scale pipes, besides, our steel pipes are equipped with other accessories as it seeks to prevent wires from scratching when threading. In addition to flattening inside or outside weld joints, we can also ensure the surface is glossy with solid structure.
