Manways

Customizable

We understand that unique tanks require unique manways, so we offer customized specifications such as pressure ratings, extended collar lengths, material types, lift/spring assist, CRNs, and more.

Styles

Depending on your industry, tanks can vary in design and size, which can, in turn, affect the style of manway needed for the job. That's why we carry over 30 options, including round, oval, rectangle, and cone-shaped manways. We have something for your application, whether it's an atmospheric cross-arm manway or a 13-lug, high-pressured T-bolt style manway. 

Lift Assist

The Mueller Lift Assist, a new design recently introduced to the market, differs from the original "spring assist" manways. It uses nitrogen cylinders that allow the user complete control while accessing the inside of their tank.

ASME Code vs Non-Code

From atmospheric storage tanks to high-pressure processing tanks, we have you covered. We have a variety of economical, non-pressurized manways up to pressure-rated ASME code manways like the MC-56 or MC-150.

3-A Sanitary Standard

If your process requires sanitary equipment to ensure the safety and cleanliness of the finished product, our 3-A Sanitary oval manways, like the MC-1 and MC-3-70, could be the solution you are looking for. 

Finish

Material finishes vary across industries. We have options from a 2B Mill finish to a sanitary mirroring #7 (320-grit) finish and everything in between.

Material Types

Different jobs have different needs, which is why we offer a variety of material types for your manway. Our most common material types are 304 or 316 stainless options, with sanitary applications often requiring 316 material. For more corrosive jobs, you might need something more exotic, such as duplex or Hastelloy. Jobs requiring visual inspection can easily be accomplished with a Mueller glass manway.
