Manway Entry Tanks From Precisioneering
Top Entry Manway Tanks
Utility and Hinged manways are designed for atmospheric pressure and tanks that have a few inches W. G. negative ventilation pressure. If manway covers are required to contain gas pressure developed during filling, additional fasteners are required.
Side Entry Manway Tanks
Side entry manways are considerably more expensive than top entry. They are a good investment if the tank must be entered on a regular basis. Precisioneering's design approach treats the installation of a manway similar to the installation of a large nozzle under Section Eight of The Boiler Code, wherein, all material removed is replaced around the hole in a manner that all stresses are carried around the manway. Manways are rated at 10 psi minimum.
