Our History

1968 Clintonville PA Branch Opened:

William L. McCarrier Sr., founder of Interstate Pipe & Supply in 1968, retired in 1995. Bill Sr. also served as a Butler County Commissioner from 1996-2000 & 2012-2016. You can still find Bill Sr. at the Butler location from time to time!

Bill McCarrier Sr., a high school math & physics teacher, purchases Phipps Pipe & Supply Store in Clintonville after working there for a couple of years. He establishes the first Interstate Pipe & Supply (IPS) branch with the purpose of servicing the oil and gas industry as well as contractors, plumbers, water well drillers and homebuilders. The ““Service Means Business”” philosophy is established with the “go the extra mile for every customer” commitment. Later, Bill Sr. hires two salesmen to build a larger customer base. One of the salesmen was a two-career salesperson, affectionately known as the “barber salesman” who managed his barbershop and sold products for IPS. 

1972 Titusville PA Branch Opened:

Bill Sr. wanted to increase customer service in the Titusville area. The “Service Means Business” focus is underscored with expanded product lines and the introduction of the Pirates Ticket customer appreciation program.

1982 Butler PA Branch Opened:

IPS buys Keystone Industrial Supply in Butler, PA. and expands the “Service Means Business” platform by increasing IPS’s footprint in Western Pennsylvania.

William McCarrier Jr., President and Controller. Enjoys riding his Harley and spending time with his family.

Shortly after buying Keystone Industrial it was moved to its current location in Butler and later the name was changed to Interstate Pipe & Supply Co. to match the other locations.

1990 Washington PA Branch Opened: 

IPS buys Waybright Pipe and Supply which had 2 branches, one in Claysville PA and one in Ripley WV.   IPS moved the inventory from these 2 locations to open a new branch in Washington PA.  IPS’s footprint increases again with the “Service Means Business” customer focused platform.

1994 Ownership Change

Bill Sr. retires on December 31, 1994 and sells the business to his three sons, Bill, Brian and John.   John leaves the business in 2010 to pursue other ventures.  Brian who acted as President from 1995 to spring of 2016 passed away in April of 2016.  Bill Jr. who had been Vice President from 1995 to 2016 becomes President after Brian’s passing.

Brian McCarrier, Bill Jr.’s brother, served as company president from 1995-2016. After a courageous battle with Melanoma, Brian passed away at the age of 52 in April 2016.

Other Key IPS Milestones: 1983-2017

  • Employment expansion – IPS continues to look for good people to hire and train so IPS can continue our “Service Means Business” into the future.
  • Technology is a key factor- IPS has always used the latest technology to help increase their ability to service customers.
  • Generational Employees – It is not uncommon for IPS to employ several generations of employees, usually a father and sons. Currently we have 2 such examples.
  • New Products Introduced – IPS is constantly reviewing our product lines and introducing new products into the mix. This guarantees our customers will have available to them products that will make their jobs easier.

2018 Grove City Branch Replaces Clintonville Branch:

With the Grove City branch addition, IPS is strategically positioned (proximity to Interstate 79) to better meet the needs of their customer base which includes the commercial and residential construction businesses, as well as the Marcellus gas industry.
