National Inspection Services Acquires Magnum Midstream

National Inspection Services is proud to announce the acquisition of Magnum Midstream effective November 27, 2019. This purchase expands the service coverage for National Inspection Services into the Northeast region of the United States.
Established in 2013, Magnum began as a small group of NDT technicians in Hickory, Pennsylvania.  It all started with an idea: If you build your company on values of quality and service, then success will follow.  Magnum has grown its service coverage throughout Pennsylvania, West Virginia, Ohio and Texas.   The reputation for quality that Magnum was built on has earned the company an esteemed reputation in the midstream sector of the oil and gas industry.
That same quality service Magnum was founded on continues in an exciting new phase for the company as the Northeast region for National Inspection Services.   Neil Marks, President and Chief Executive Officer of National is quoted as saying;
“National is proud to have the Magnum team onboard because they share a dedication for quality service and exceptional standards. With this addition to our team, National now has eight locations and services customers throughout Louisiana, Texas, Colorado, Wyoming, Pennsylvania, New Mexico, West Virginia, and Ohio.” 
National looks forward continuing its mission of providing quality nondestructive testing services throughout the United States. We will keep you updated on our expanding service lines.  We extend our gratitude to all of our customers’ who have helped us get to this point.
