In 1980, David Cohen founded United Pipe & Steel with just $5,000. A pioneer in master distribution, David recognized that LTL shipments, along with more flexible logistics services and competitive pricing, provide significant value to plumbing and heating wholesalers looking for steel pipe. From one steel pipe distribution center in the Northeast, United Pipe & Steel has expanded to twelve national distribution centers that stock steel, copper and plastic pipe products for all industry segments.

In February 2019, after 40 years in the industry, David Cohen announced his retirement from United Pipe & Steel.  In 2019, it was also announced that United Pipe & Steel Corp. and Merfish Pipe & Supply Co. would be combining under Merfish Pipe Holdings (MPH), an entity that is majority owned by One Equity Partners.  This merger will have a meaningfully positive impact for customers, enhancing the basket of products they are able to secure from either company. Gerald Merfish is now Chairman of the Board of MPH and Greg Leidner, the CEO of United is the new CEO of MPH. At this time, both companies are continuing to operate independently.
