Our Roots

MOPIPE’s 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 1950s, we began to supplement our manufacturing product group by turning to import of Steel Merchant Couplings from Germany and Malleable Iron Fittings from Japan in the 1960s.  During this 1960s Bill served as President of the National Pipe Nipple Manufacturers Association when there were no less than 60 such manufacturers in the United States.

Today there is 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 1970s 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 1990s 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.
