Vessels or Tanks

Alloy

ASME Vessels. Generally refers to pressure vessels and alloy high-pressure vessels, the design of which conforms to specifications, materials, and requirements of pressure vessel code adopted by the American Society of Mechanical Engineers. A pressure vessel is a closed container designed to hold gases or liquids at a pressure that is different from the ambient pressure. These vessels, usually cylindrical, have a body with end caps, called heads, fitted to the ends of the body. Pressure vessels are designed to operate safely at a specific pressure and temperature, referred to as the "Design Pressure" and "Design Temperature".

Cryogenics

Cryogenics Vessels. These vessels are designed to handle liquified gases, such as liquid nitrogen and liquid helium, at the lowest attainable temperatures. Some specialty vessels are designed to store cryogenic fuels, such as hydrogen and oxygen. Most cryogenic vessels are made from carbon or stainless steel, and are designed in accordance with ASME specifications.

Fiberglass

Fiberglass Vessels. These vessels can be either pressure vessels designed to operate safely at a specific pressures and temperatures, or non-pressure vessels designed for use in gravity controlled and low-pressure systems. Fiberglass vessels are often chosen for corrosive process systems. They can withstand higher temperatures and pressures than ordinary thermoplastic materials. Their corrosion and chemical resistance makes them well-suited for general chemical processing applications. Fiberglass vessels can be used in a wide variety of corrosion resistant conditions, have low thermal conductivity, and low long-term maintenance costs

Field Fab

Field Fab Vessels. These are vessels, or storage tanks, that have been specially designed to be quickly erected on location in the field, instead of being fabricated in a factory and shipped to location. Field fabricated vessels include structures such as: stainless steel tanks, pressure vessels, evaporators, columns and equipment for use in the dairy, food, grain, ethanol, chemical, beverage, wine and brewing industries. Experienced providers can field fabricate tanks with capacities of up to 500,000 gallons

Glass Lined

Glass Lined Vessels: Glass lining is a form of porcelain enamel, much like the material applied to bath tubs and sinks. It forms a permanent chemical and physical bond with the metal surface. The finished surface is extremely smooth and very hard, making glass-lined vessels ideal for handling chemicals that tend to adhere to the inside of bare metal vessels. The glass lining is non-permeable; resistant to corrosion, abrasion, high temperatures, and thermal shock; and has a wide pH range

Kettles

Kettles. These are top loaded vessels designed to apply radiant heat to the vessel’s external surface. Some, supplied with pressure covers, can be used at high pressure. Heating elements radiate uniform heat directly to the outer surface walls of the vessel from which it transfers to the material being heated. Industrial kettles, usually made from welded carbon steel, stainless steel, or copper, and jacketed with high-grade insulation, can support temperatures up to 650°F. All are supplied with appropriate control instrumentation, and some are provided with motor-driven agitators or scraper blades.

  • Code: 18-01-05

Mechanical

Mechanical Vessels: Expansion Tanks & Air Receivers. An expansion tank is a small tank used in closed water heating systems and domestic hot water systems to absorb excess water pressure caused by thermal expansion or water hammer. An air receiver delivers or stores short-term demand that either exceeds or is less than an air-compressor’s capacity.

Poly - Blow Molded (See Assman tanks)

Polypropylene Vessels. These vessels can be either pressure vessels designed to operate safely at specific pressures and temperatures, or non-pressure vessels designed for use in gravity controlled and low-pressure systems. These vessels are lighter than those made from other materials. Their smooth inner walls resist the formation of deposits. Though they do not have the strength of metal vessels, they have enough tensile and burst strength to withstand operating pressures encountered in most service conditions. They can withstand external shocks that could cause failure in more brittle materials. They are resistant to water, nearly all acids, alkalis, salt solutions, and other corrosive liquids and gases.
