BENMAR Fabrication is a leader in custom ASME pressure vessel fabrication.  Our customers depend on us to design and fabricate made to order pressure vessels.  We excel in unique pressure vessels which not only meet the clients needs, but also the ASME guidelines. 

BENMAR Fabrication holds an ASME 'U' stamp for construction of new pressure vessels and a National Board 'R' stamp for Repairs/Alterations of pressure vessels.  Our ASME reviewed Quality Control Program ensures that all our products have met the requirements for design, construction and testing.  Our experienced team of Engineers has a great deal of ASME Code knowledge and a strong understanding of how to optimize code guidelines to provide a cost effective vessel design.   

We specialize in custom design pressure vessels which vary in size, design parameters, and materials of construction.  BENMAR Fabrication's facility is capable of fabricating custom vessels and tanks as large as 144" diameter.  Our certification also allows us the ability to fabricate new vessels or perform repairs/alterations on site as well as in our shop in Green Bay, WI.  

All welders at BENMAR Fabrication are certified to ASME Section IX and utilize numerous welding processes as well as various materials – carbon steel, stainless steel, and duplex stainless steel.

Our Professional engineering team will work closely with you to help determine your specific vessel needs.  We will then translate these design discussions into a 3D design for your review and acceptance.  These design discussions provide the foundation for a quality vessel and lasting relationship with you – our client.
