Manways
CMC Letco designs and fabricates manways for both ASME code and low pressure/non-code applications.
Cross Arm Manway
Our CMC18A manway is designed for atmospheric service above the liquid level of a tank. It features a quick opening design, easy gasket replacement, and can be fabricated from nearly any stainless steel or nickel alloy material.
Bolted Manway
For higher pressure applications, our LMB series manway can be custom built to withstand higher pressures and temperatures than many quick opening or tongue-and-groove manways. It features a flat gasket, and is ideal for applications requiring a 150# or 300# class flange, but without the extra weight of a blind flange. Hinges, davits or spring assists can be added to any manway.
