Industrial Degauss will be exhibiting the IDMAG Pipeline Demagnetizer and our demagnetization services @ the Pipeline Pigging & Integrity Management Conference! Come check out our booth in person from February 19-21 in Houston, Texas to learn how we can help with any magnetism related issues.
The pipe used in the fab shop was magnetized and the IDMAG Pipeline Demagnetizer was used to demagnetize the pipe ends. A magnetic survey was performed at the beginning with a high measurement of 90 gauss. Within 20 minutes, the equipment was set up and the pipe end was degaussed. The resulting value was reduced … Read more
We are exhibiting the IDMAG Pipeline Demagnetizer and our demag services at the World Gas Conference in Washington DC. Come see our equipment in person and learn how we can help with any magnetism related issues such as magnetized pipe, arc blow, magnetized rotors and shafts, etc.
Magnetized pipe causes arc blow, porosity and other issues during welding. If you ask around you will hear many different methods – reverse the polarity of the leads, wrap an odd number of welding leads around the pipe, use an AC welder, strike it with a sledgehammer, lay the pipe East-West… none of them will … Read more
A valve was being installed on a 42″ pipeline. The line had been pigged in the past and the contractor knew that the pipe was going to be heavily magnetized and would need to be demagnetized prior to welding. Using a welder and wrapping the welding leads would not be enough to demag this pipe. … Read more
Depending on who you talk to about the issues with magnetized pipeline, they all seem to use different terms. Degauss, demagnetize, demag are a few that you hear thrown around. Do they mean the same thing? For most purposes – YES – they all mean the same thing. “Degauss” means: to remove unwanted magnetism from … Read more
Many pieces of magnetized pipe were delaying the project. The IDMAG System was used to successfully degauss the pipe ends prior to welding.
A 20″ diameter, Schedule 140 steam line header was severely magnetized, hitting around 140 to 170 on the gaussmeter. The magnetism was causing arc blow and the inability to weld. The IDMAG System was used to demagnetize the pipe and allow welding to proceed without delay. :end
Magnetized pipe was known to exist from prior outages. The customer requested the equipment prior to the start of the project consisting of 10″ and 18″ diameter steam lines. The IDMAG pipeline demagnetizer was sent to the site to remove the magnetism. “Got the equipment. Wrapped the valve, and it worked!”
