Access Manway / CNC 171 / Access Hatch
CNC 171 / ACCESS MANWAY - Access Manway Cover for Bulk Storage Tanks
The CNC 171 Manway or Access Manway, also known as an access Hatch, are secured access manholes designed to seal the tank up to 2.5 psig, with access obtained via the locking seal unlike the emergency manways which will relieve at a given pressure, this is ideal if you you require a locked / sealed manway with access for maintenance and cleaning
The access manway is secured by a transverse beam which is attached to the centre of the cover. This ensures even distribution of the holding down force to form a gas tight fitting to 2.5psig.
The access manway is manufactured by MTP in our UK manufacturing plant to exacting quality standards and backed by over 40 years experience as manufacturers. Manway sizes range from 10″ (250mm) to 26″ (650mm), non standard manway sizes are available upon request.
Access Manway is non-sparking low pressure manhole cover which provides easy access to low pressure storage tanks for maintenance and cleaning purposes.
