API 5L X70 seamless pipeline steel which Grade X70 means 70000 PSI minimum yield strength and 82000 PSI minimum ultimate tensile strength. API 5L X70 seamless pipeline steel is use in pipeline transportation systems in the petroleum and natural gas industries also applies to pipe piles in which the steel cylinder acts as a permanent load carrying member.

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.

Our products all have pretty physical appearance with smooth outside welding. Compared with some other suppliers, we use a flat knife for scraping the weld line. Besides, the visual weld geometry size is in line with the actual requirements of different applications. On the other hand, tube shape mutation is easy to cause stress concentration. If the excess part of the welding is polished off in the pipe production process, this will somewhat eliminate part of the stress concentration. In addition, our workers are all skilled in the post treatment of pipes, who all have excellent professional experience for many years.
