Redefine The Automatic Welding Of Thick Wall Pipe Spool

2016-12-21 Redefine The Automatic Welding Of Thick Wall Pipe Spool

Welding is one of the most key technology link of pipe spool prefabrication, also an important issue for fabrication to improve the efficiency and quality. Currently more and more enterprises have purchased, or are going to purchase automation equipments, so as to increase pipe spool fabrication efficiency and reduce the cost, which is especially urgent in automatic welding of thick wall pipe spool.


Current Situation In Automatic Welding Of Thick Wall Pipe Spool

1)        Under the ASME standard, pipe spool with thick wall usually refers to wall thickness above 22mm, which needs compound V or U-shaped bevel. Due to the narrow groove, this kind of pipe spool is difficult to realize automatic welding.

2)        Thick wall pipe spool most are alloy steel, which need to be preheated before welding and heat treatment after welding, the process is complex and difficult to control quality.

3)        When welding stainless steel thick wall pipe spool, it will waste much protective gas and bring high welding cost. Even common material thick wall pipe spool welding need huge filler metal.

4)        Thick wall pipe spool is heavier, difficult to fit up. Manual welding efficiency is low and it needs heavy worker labor.


NAEC Breakthrough In Automatic Welding Of Thick Wall Pipe Spool

Currently, NAEC brought a big breakthrough in automatic welding technology of thick wall pipe spool, and implemented the full automation welding of thick wall pipe spool with TIG root pass and SAW fill and cap pass in RAPID project. It truly offers a guarantee in quality, efficiency and cost for thick wall pipe spool.
