Round manway
A590 (DN300-DN600)
Round manway series A590
Round manway series A590 is a simple and universal construction with central cover press. Products in this series are made of stainless steel in grades AISI 304 or AISI 316L. As standard, the manway is equipped with a plastic handwheel (optionally INOX).
This type of manhole is mounted on the top (roof) of the non-pressure tank.
A large range of mounting frame heights allows this model to be installed in stainless steel insulated tanks.
Manways series A500 with diameters DN300/400/500/600 have a smooth surface. DN380/400/420 diameters are equipped with embossed covers.
The use of stainless steel round manway series A590
Examples of applications where A590 series manways will work well:
- non-pressure stainless steel tanks,
- industrial chambers,
- technological and production equipment,
- all types of non-pressure applications in environments requiring increased corrosion resistance.
