Welded Stainless Steel Tubing-Welded Steel Pipe
The many unique values provided by stainless steel make it a powerful candidate in materials selection. Corrosion resistance, hygiene and strength of stainless steel make it an ideal choice in the Medical, Aerospace and Industrial industries. To learn more about these benefits see here. The two major categories for tubing and pipe are seamless and welded. The major difference being the seam that is on a welded tube and not on a seamless tube just as the names indicate. Seamless pipe has the increased ability to withstand pressure; because there is no weld seam it is equally strong around the entire circumference. On welded tubing the weld seam is not recognized by the naked eye and takes on the appearance of seamless. Welded tubes have excellent concentricity, are more readily available and cost effective for most applications.阅读更多 -
Stainless Steel Tubing: Welded Vs. Seamless-Stainless steel pipe
Welded tubing is produced by rolling strips of stainless steel into a tube and then welding along its full length. After welding, the weld seam, or bead, can be refined by cold rolling and forging methods or left as is.Cold forming results in smoother finishes and tighter tolerances. Welded tubing can even be drawn like seamless tubing to offer a better weld seam, and surface finish. Welded tubing can also be produced with thinner walls on larger diameter tubes, compared to seamless tubing. Because welded tubing requires less processing, it is typically quicker to produce as well as lower in cost than seamless tubing.The down side of welded tubing comes in the form of high pressure and heavy wall applications. The long welded seam causes a stress concentration point, reducing pressure ratings to 80% of comparable seamless tubing. Also, the stainless material used to create welded tubing must be thin enough to roll effectively. Therefore, heavy wall tubing is less feasible as welded tubing.阅读更多 -
Seamless pipes: their manufacturing process-Stainless steel pipe
Innovations in the metal sector do not lie solely in the creation of new alloys or in the improvement of the machines used to create them. There are also improvements in existing parts, small details that make a part more practical for a specific function, as in the case of seamless tube manufacturing.If you want to know their history, how they are manufactured and when you should use this type of tube instead of another, keep reading, because we are going to cover these and other topics in today’s post. It is our small tribute to the small big changes.阅读更多 -
不锈钢管是如何制造的？-碳钢管
原材料：该工艺从选择合适的原材料开始，这些原材料通常是钢坯或钢卷。这些材料应具有适合预期用途的必要化学成分和物理特性。管材形成：有几种方法可用于形成钢管，包括：a. 无缝管制造：i. 穿孔：钢坯被加热并通过穿孔机穿孔以形成称为壳体的空心管。ii. 旋转定径：使用旋转定径机将壳体进一步拉长并成型为所需的直径和厚度。iii. 精加工：管材可能经过额外的工艺，例如矫直、热处理和表面精加工，以满足特定要求。阅读更多 -
Breaking Down Common Steel Tube Processes and Finishes- Welded Steel Pipe
Abbreviated ERW, this is a format that signals a specific welding process – actually two processes, spot and seam welding. This process involves several specific steps where the steel is unwound and trimmed, then passed through rollers to cold-form the steel into the proper shape (circular, square or rectangular).From here, the edges are forced together into a butt joint, then welded at a very high temperature to form a flash weld. Once the weld is tested, the tube passes through various sizing rolls to achieve the proper size, and then the length is cut. The materials used here will generally be available in both hot-rolled and cold-rolled formats.阅读更多 -
谈谈不锈钢管-不锈钢管
不锈钢管是一种坚固耐用的材料，可用于结构用途，耐腐蚀，几乎不需要维护。不锈钢管的直径和种类根据应用要求和使用方式而有所不同。对于大多数人来说，管道和管材是相同的，这导致人们对这两种产品的使用产生了一定程度的混淆。由于这两种产品的横截面都是圆形，因此人们认为它们具有相同的功能。与管子不同，管子有多种形状，如方形、矩形和圆形。管道和管材之间的主要区别之一是它们的使用方式。管道是一种用于输送气体和液体的运输机制，而不是用于结构用途。它通过内径 (ID) 来测量。管材用于结构用途，通过外径和壁厚来测量。阅读更多 -

how are steel tubes made-Welded Steel Pipe-ERW Steel Pipe
The use of steel pipes was started by a Scottish inventor in 1815 connecting the tubes to convey gas for lights. In 1836, the United Kingdom had a patent for the production of seamless steel pipes by the extrusion method, but it was not until 1885 that the German Mannismann brothers invented the process of directly producing seamless pipes from bar steel. The Mannismann brothers first invented the second in 1885. The roll cross-rolling piercing machine, invented the periodic tube rolling machine in 1891, and in 1903, the Swiss R Stiefel (RCStiefel) invented the automatic tube rolling machine (also known as the head-type tube rolling machine). Later, continuous tube rolling appeared All kinds of extension machines, such as machine and pipe jacking machine, began to form the modern seamless steel pipe industry.阅读更多 -
