Penn Iron Works (PIW) started in business in 1915 as a foundry and entered
weldment fabrication about 60 years ago. The company’s quality weldments are
now in use around the globe…from nuclear power generating stations in Taiwan, Korea
and the U.S., to the Alaskan North Slope oil fields, to the Great Salt Lake, Utah, flood
control pumping station, to Saudi and other Middle East Desalination plants, to the
Nuclear Powered USN “Seawolf” and “Virginia” class submarines, to chemical plants,
mines, and municipal water pumping facilities all across the U.S., Asia and South America.
A core of dedicated and highly qualified men and women are the foundation of the company.

Most fabrications are made to clients’ design specifications;  PIW has the ability to do
custom design work and provide drawings as needed in the manufacture of
replacement equipment.  Fundamentally PIW’s focus and concentration, in the post
industrial America, is divided into four areas:

•	In providing “high end” complex custom fabrications in a variety of different materials (including the exotic) and involving demanding Quality requirements.
•	In servicing the Nuclear Power Generation industry with a variety of equipment either through Original Equipment Manufacturers or through the individual plants themselves. Such equipment includes, fabricated pumps, valves, piping and other components within the confines of the nuclear power generating stations.
•	In providing quality fabricated and machined equipment for the Armed Services of the U.S. and other friendly nations, such as the U.K. and Canada. Our total business with this segment is expected to grow dramatically in the upcoming years.
•	In servicing plants where a quick turn-around or replacement are needed through the conversion from castings to fabricated components including “reverse-engineering” where required. The range of materials involved here is wide and the size and weight of equipment can be as heavy as 50 tons in one piece.

About half of  PIW’s business is in stainless steel and about 35% is in other exotic materials such as duplex stainless steel, aluminum bronze, nickel aluminum bronze, aluminum, pure nickel, Hastelloy, Inconel, and Monel. PIW uses more than 200 approved procedures to weld these materials to themselves, to overlay a less corrosion resistant one with a more corrosion resistant one or to join dissimilar materials. These procedures include the SMAW, FCAW, GMAW and SAW processes, including strip overlay. To ensure compliance with the most stringent quality standards, all Penn Iron Works weld procedures, welders, welding operators and fitters are qualified and certified to ASME Section IX or MIL-STD-248.
