A manway is a porch or hole leading into a zone like
a bin, sewage line, or submarine. The manway seals the exterior of the object
from the inside and acts as a shield from the contents inside. Manways are used
in a variety of sectors and have applications all around the globe. They are
also employed in a place like food sectors where hygiene is the priority. Pressure manway is usually found and used in the following places:
Manhole
Manhole covers are the simplest form of shelter on a
manway. These shelters protect the manways to underground electric systems,
underground sewage systems, and other underground systems. These covers are
usually made with stainless steel as this material protects from corrosion,
rust, and other damaging factors that make the manhole covers hard to remove
when workers need to access the area.
Submarine
A submarine manway is a passageway between the
inside and outside of the submarine. These are vitally essential to prevent
water from getting access to the submarine. These covers are often manufactured
from stainless steel to avert corrosion and rust from occurring because of the
constant presence of water. Submarine covers are some of the most intricate
covers that offer pressurized seals to secure the people inside the submarine.
Sampling Ports
A sampling port is a smaller manway inside of a huge
container or other storage areas. These ports grant convenient access to the
contents inside an area or tank for human testing. The ports are often manufactured
from stainless steel for protection and corrosion resistance.
Inspection
Inspection covers protect the inside of a container
or storage room with a shelter that not only stops something from getting into
the container but also prevents the material from getting out. The covers are
unbolted when an inspection of the inside contents is required.
