Round manway
A540 (DN200-DN600)
Round manway series A540
Round manway series A540 is manufactured from AISI 304 or AISI 316L stainless steel. As standard, the manway is equipped with plastic handwheels (INOX handwheels are available as an option). The number of handwheels depends on the diameter of the manway.
This type of manway is mounted in the top of the stainless steel tank. The manway series A540 opens upwards and is held in the open position by a hinge. Opening of the manway is facilitated by a handle located on the cover.
A wide range of mounting flange heights is available, so the manway can be easily built into stainless steel insulated tanks.
Manways of the A540 series with diameters DN200/300/400/500/600 have a smooth surface. DN380 and DN420 diameters are equipped with embossed covers.
The use of stainless steel round manway series A540
Examples of applications where A540 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.
