Aug 10, 2015 · Furnace welding production of welded pipe is welded tube billet, the heating in the heating furnace to welding temperature 1300 ~ 1350 DHS C, and then through the pipe die and forming welding machine pressure forming and welding tube, furnace welding production of welded pipe size range 10 x 1.9 ~ 10 mm to 114 mm, mainly used for conveying water, gas pipe and heating pipes, also can be used as a structure.Furnace welding points chain furnace and continuous furnace welding Whats the difference between DOM - SHEW-E STEEL PIPEJan 31, 2018 · Cold Drawn Welded (CDW) tubing Produced from a steel strip by cold forming, electric resistance welding (ERW) and cold drawing.During these processes the sizing (wall thickness, inside and outside diameter), as well as weld integrity and surface finish is closely controlled to produce tube of the required size and mechanical property characteristics. cold drawn welded tubes, cold drawn welded tubes Suppliers A wide variety of cold drawn welded tubes options are available to you, such as 300 series, 600 series, and 400 series. You can also choose from jis, astm, and aisi cold drawn welded tubes, as well as from q195-q345, a53-a369, and stba20-stba26 cold drawn welded tubes, and whether cold drawn welded tubes is bending, cutting, or welding.
Cold-drawn steel pipe generally takes several times pulling in between each drawing a corresponding stress relieving, to ensure the smooth progress of the next cold drawn. Cold-drawn steel pipe. From the appearance of cold-rolled seamless steel tubes tend to be small in diameter, hot-rolled seamless steel tubes are often large diameter. Cold-rolled precision seamless steel tube is higher than hot-rolled seamless steel tubes, the price is also higher than hot-rolled seamless steel tubes.
