Pressure vessels most often contain fluids, vapors
or gases at pressure levels greater than that of atmospheric pressure.
Pressure vessels contain a wide variety of substances used for various
industrial applications including the chemical, pharmaceutical, food
and beverage, oil and fuel and plastic industries. The substance contained
and the industrial application of the pressure vessels determines such
design components as vessel material, size, shape, temperature and pressure
level. Vessel creation and maintenance consist of structured steps in
which the above factors are determined. When a substance is stored under
pressure, the potential for rupture and leakage exists. Improper vessel
design and maintenance increase the risk of pressure vessel failure,
posing a serious safety hazard. This risk increases when vessel contents
are toxic or gaseous substances. Engineers take precautions when creating
a pressure vessel to limit the occurrence of vessel failure. The division
of vessel creation into steps, which include design, construction, testing
and inspection, keeps safety hazards to a minimum.
In the design process, engineers determine the logistics of how pressure
vessel manufacturers will create the vessels. Engineers must determine
the pressure level, temperature, material components, size and shape.
Engineers also consider the corrosion and abrasion potential of the vessel
before deciding these factors. Pressure levels are also taken into account
before deciding upon a material and shape. Pressure vessel manufacturers
fabricate a range of pressure vessels; from a few hundred pounds per
square inch (psi) to measuring up to 150,000 psi. Temperature must also
be considered before deciding on a material, as materials like steel
are susceptible to damage from exposure to extreme temperatures. Materials
can include carbon alloy steel, stainless steel, titanium, zirconium,
aluminum, nickel alloys and niobium. Sizes range from small vessels holding
only a few ounces of a substance to very large vessels with up to a 95,000-gallon
capacity. Most pressure vessels are cylindrical; however, contents under
extremely high pressure are often placed in stronger spherical vessels.
Because of the above factors and the fact that pressure vessels can have
a temperature range that exceeds 750°F, safety is of large importance.
There are standard regulations and formulas to which the pressure vessel
manufacturers’ designs adhere in order to avoid potential hazards
associated with pressure containment. The American Society of Mechanical
Engineers (ASME)
provides a Boiler and Pressure Vessel Code on which engineers base pressure
vessel design. Although the ASME Code remains the most common standard,
engineers also follow other codes, such as that of the American Petroleum
Institute (API). Rigorous analyses for complex pressure vessels are created
when standard design rules do not apply. In such instances, engineers
conduct intensive mathematical and scientific analyses to ensure design
and construction methods meet the stringent requirements of pressure
vessels: material, size, shape, temperature and pressure level of the
pressure vessel, as well as personal preferences.
Engineers usually create vessels using one of three processes. Forging
involves the formation of metal parts through the application of heat
and pressure. Welding involves melting two similar metals together. Brazing
involves the joining of metals by filling the space between them with
a nonferrous metal. Testing of the pressure vessel ensures design technique
success, proper vessel operation and certification approval. Regular
inspection remains necessary to ensure that the vessel continues to meet
industrial standards and safety requirements. The National Board of Boiler
and Pressure Vessel Inspectors remains the worldwide standard for pressure
vessel inspection, alteration and repair.
Types of Pressure Vessels Including: Pressure Tanks, Water
Pressure Tanks, Autoclaves, Kettles, ASME Tanks, Pressure Vessel Manufacturers,
and
Stainless Steel Pressure Vessels.
ASME tanks are pressure vessels that meet the standards set by the American Society of Mechanical Engineers.
Autoclaves are closed pressure vessels that use steam and high pressure to sterilize instruments.
Cookers are a
type of pressure vessel that are used to bring about a physical change
in their contents. Examples of this are digesters, vulcanizers and rendering
tanks.
Fired pressure vessels
utilize fuel combustion to generate heat. Examples include boilers,
furnaces, gas water heaters and autoclaves.
Heat exchangers include
a variety of configurations of vessel equipment in which heating or
cooling is performed on one side of the vessel
and the opposite conversion on the other side. (http://www.heatexchangers.org)
Kettles are pressure vessels that use steam to heat fluids.
Pressure tanks are vessels that hold contents at pressure levels greater than atmospheric pressure.
Rotating pressure vessels
usually contain steam, which is then used to dry articles such as paper,
fabric or plastics. The materials are passed over the rotating vessel
via rollers to come into direct contact with the emitting steam.
Steam jacketed vessels
are used to heat liquid to a moderate degree. Steam is distributed between
the inner and outer shells of the vessel and is used in the commercial
preparation of foods such as candy.
Storage vessels
include air tanks, hot water tanks, propane or other gas tanks, which
contain contents under pressure when needed.
Thick walled pressure
vessels are the least
common. They are any cylinder [shell] ratio that is 10% or more
the ratio of the thickness to the inside diameter.
Thin walled pressure
vessels are one of the most common of the vessels. They are any
cylinder [shell] ratio which is 10% or less of the ratio of the
thickness to the diameter, or a pressure vessel is thinned walled if
the diameter is 10-times or more of the thickness.
Transportable vessels
are in contrast to those that are stationary. Examples of such are those
are road or rail tankers; propane and gas tanks are considered to be
in this category.
Unfired pressure vessels
are not exposed to direct heat. Generated heat, if any, is produced
through electric heat or steam, and sometimes through the chemical reactions
of vessel contents.
