Round manway
E51 (DN502)
Stainless steel round manway E51
Stainless steel round manways E51 with a diameter of 502 mm are designed for installation in the upper part (roof) of stainless steel tanks. They are suitable for tanks intended for storing various liquid products in non-pressurized conditions, as well as for other process equipment.
A characteristic feature of the E51 manway is an arm equipped with two support points. This guarantees the stability of the opening and closing of the cover, and also provides increased strength to the whole construction.
The hinged manway cover opens upwards. The ribbing on the cover usually includes space for welding the end of a breather valve or a small, flat sight glass. The range of available mounting frame heights (see tab: dimensions) makes the manway suitable for installation in stainless steel insulated tanks.
