【Tube mill process】: welded pipe manufacturing process | tube mill production line

tube mill production line: In the Tube mill process, Steel pipes are long, hollow tubes that are used mainly to convey products from one location to another. They are produced mainly by two distinct manufacturing methods which result in either a welded pipe or a seamless pipe. In both the manufacturing methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the hot steel billet out into a seamless pipe or forcing the edges of flat steel strip together and sealing them with a weld. In the welded pipe manufacturing process or steel pipe manufacturing process, the pipe is manufactured by cold-forming a flat sheet of steel into a cylindrical shape. Then current is passed between the two edges of the steel cylinder to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. manufacture of roll forming machine for subscribe us don't click this link !! https://bit.ly/2TETQpm we are the professional manufacturer for roll forming machine in China and we export roll forming machinery all over the world. please check our other video for this machine in these links:    • ROLL FORMING PROCESS: how roll forming mac...      • Roll Forming machine: Warehouse structure ...      • Wuxi LOTOS Roll Forming Machinery Manufact...      • 2 & 3 wave guard rail roll forming machine...      • tube mill production line      • High Speed High Speed Stud and Track Roll ...      • Rollforming Systems Machine - Roll Forming...      • How Roll Forming Machines Work      • C Purlin /Channel Roll Forming Machine Man...      • scaffolding walk board roll forming machine   ▼ ▽ FIND CHANNEL NOTES ELSEWHERE Instagram: https://bit.ly/2Rgw7is google plus: https://plus.google.com/u/0/103979094... telegram: https://t.me/lotosvictory facebook:   / wuxilotosforming   youtube:    / lotosforming   ▼ ▽ CHANNEL    / lotosforming   Wuxi LOTOS Roll Forming Machinery Manufacturing Mobile / Telegram / Whatsapp /Wechat : 008618914131008 Email: [email protected] Website: http://www.lotosforming.com/ http://www.lotosforming.com/door-fram... http://www.lotosforming.com/roofing-s... http://www.lotosforming.com/rolling-s...
