ASTM B725 - Welded Pipe

ASTM B725 Pipe

ASTM B725 specification covers Monel 400, Alloy 200 and Alloy 201 Welded Pipe. Alloy Pipes by processing flat material into spiral pipes. The ASTM B725 UNS N02200 Welded Pipe, ASTM B725 UNS N04400 Welded Pipe, ASTM B725 UNS N02201 Welded Pipe have strong resistant to corrossion in sea water.

Scope And Manufacturing

ASTM B725 Pipe should either be welded, annealed or stress relieved and made from the flat-rolled alloys by an automatic welding process without any filler metal additions. The pipes should also be cold worked after welding to ensure the development of optimum corrosion resistance in the weld area and base metal during the final heat treatment. The pipe ends are fusion welded one to the other to make an endless strip feed into the spiral mill. The prepared steel is fed into the mill at an angle to get the required final diameter. The pipe is formed into a continuous spiral tube and the root is tacked in place, most likely using automatic gas metal arc welding (GMAW or MIG). This tack weld helps both to hold the round shape and ensure weld geometry remains constant while the full spiral weld is deposited. The second SAW welds is generally made when the pipe has rotated to the top or 12 o’clock position. The outer diameter SAW pass remelts the pipe center part or root of the inner diameter SAW to provide good alloy homogeneity. Both welds complete the joint and final welded pipe is obtained. ASTM B725 specification covers UNS N02200 Nickel Alloy which is an Alloy 200, UNS N02201 i.e. Alloy 201, UNS N04400 i.e. Monel 400 alloy welded pipes.

Monel 400 Welded Pipe, which is stronger than pure Nickel is exported by Siddhagiri Metals and Tubes. Alloy 200, Alloy 201 and Monel 400 Alloy pipes have excellent resistant to corrossion against flowing sea water and are widely used in a number of industries. These alloy grades can be fabricated readily by hot, cold working, machining, and welding and other processes.
