About Us 2018-02-21T16:58:12+00:00


Founded in 1933 as a pipe nipple and machine shop operation, MOPIPE is now approaching our 85th year of manufacturing tailored pipe nipples and related specials to accommodate the PVF, Petrochemical and Construction industries on a national basis.  A privately held family business, MOPIPE is an independent company who responds to your needs all under one umbrella, a most personalized service from our location in St. Louis, Missouri.

Our extraordinary longevity can be attributed to the steady leadership of Bill Roewe, our President. Bill joined Missouri Pipe Fittings Company (MOPIPE) in December of 1952 after serving in the Army Air Force from 1943-1946, graduating from St Louis University in 1949 and as an auditor for Mobil Oil from 1949-1952.  After focusing on our pipe nipple manufacturing  operation throughout the 1950’s, we began to supplement our manufacturing product group by turning to importing of Steel Merchant Couplings from Germany and Malleable Iron Fittings from Japan in the 1960’s.  During this 1960’s Bill served as President of the National Pipe Nipple Manufacturers Association when there were no less than sixty(60) such manufacturers in the United States.

Today there are only a handful of active  American Pipe Nipple Manufacturers.  Mr. Roewe continues to be an active driving force behind our company to this day.  In the 1970’s additional steps were taken, importing more products from a variety of overseas vendors.  Our relationships with some of those vendors continue to thrive many years later.  During this same period we added an additional 50,000 square feet for manufacturing purposes and another 25,000 square feet for warehouse purposes.  Further expansion in the 1990’s brought on  another 30,000 square feet of warehouse space.

What Makes MOPIPE Stand Out

Our core business of manufacturing pipe nipples extends well beyond the everyday stock items.  We have produced tens of millions of non-stock related piping components tailored to your requirements for special lengths, special threads or special cuts.  Over the years, we have continually added various product groups that go hand-in-hand with our manufactured pipe nipples – whether it be fittings, couplings, flanges or hammer unions in carbon steel, stainless steel, brass or aluminum.

MOPIPE is Here To Stay

We have witnessed many changes in the industry since 1933.  In the last fifty years over 90-95% of our competitors have come and gone, often to be replaced by a new competitor or at times a consolidation with another firm. But as Missouri Pipe Fittings continues to stand up to the test of time and complete our 85th year in business, it is only logical to assume we’ll be here tomorrow to take that call.
