INDUSTRIAL HEAT EXCHANGERS & PRESSURE VESSELS

CAPABILITIES

At Adamson Global Technology Corp. we have modern, industrial-sized equipment to get the big jobs done to your specifications. Our head machine can turn out heads up to 14' diameter and up to 1" thick. The Haeusler Plate rolls can roll 2 1/2" thick x 10' wide plate down to a 10' diameter. They can also roll down to a diameter of 24" at 10' wide and 1" thick. There are 70 automatic and semi-automatic welding machines including Hobart Cyber-Tig 300 for tube-to-tube sheet welds. Adamson's Staff Welding Engineer assisted in developing this technology. We have a fully computerized six spindle drill with a 96" wide drilling and milling capacity that can drill up to 2" diameter holes through 5" plate. We also have a single spindle tape controlled drill with a 13'6" diameter bed with a drilling capacity of 11" thick. At Adamson we can drill a true hole through 9" thick carbon steel! Our 400-ton brake has a throat width of 12'. We utilize engine lathes of 24" and 14" and turret lathes of 60" and 24" diameters. Horizontal and vertical boring mills to 72" in diameter are also available. For use in the manufacturing of heat exchangers, we have electronic and air operated tube expanders for 1/2" to 2" tubes plus a hydraulic tube bender that handles tubes up to 1-1/4"OD. The finest welding equipment operated by expert welders is available for use at all required stages of the manufacturing process. In our Quality Assurance Department, non-destructive testing equipment includes; liquid penetrant, ultrasonic, Brinnell hardness testing, magnetic particle inspection equipment consisting of Y5 yokes, and several X- ray units. Pressure-testing equipment includes Hydro Max, PSIG 5000 and Air Max, PSIG 100.

Scope of Fabrication and Services

Shell and Tube Heat Exchangers, Pressure Vessels, Towers, Columns, Feedwater Heaters, Reactors, Condensers, vaporators, Desuperheaters, and Storage Hoppers-Bins, are customer fabricated to your specifications. Duplicates of any units previously supplied by Old Dominion Fabricators are also available. Mechanical and Thermal design functions are offered through our in house consulting services by way of B-JAC International. B-JAC Internationalprovides the state of the art in computer optimized thermal and mechanical designs. Using a powerful intuitive software package with interactive capabilities, we can quickly pose any number of "What If" cases to evaluate different variables before selecting a final design. Design standards include: A.S.M.E., T.E.M.A., AD Merkblatter - DIN, CODAP, and others.

PRESSURE VESSELS

Whatever size or type of pressure vessel you require, Adamson Global Technology Corp. has the expertise, the facilities, and equipment to produce. We strictly conform to all requirement of ASME (Sections I,IV, VIII Div 1) as well as AWS, and AWWA. We can produce units (tanks, columns and towers) up to 14' diameter, utilizing up to 3" thick material and a final lifting capacity of 95 tons. Let us serve your needs.

CONSTRUCTION

All Adamson pressure vessels are of ASME welded construction. All threaded openings, manholes, and nozzles are reinforced and installed by fusion welding. Vertical or horizontal construction can be provided as required. There are many construction codes governing design and fabrication of tanks and pressure vessels required by industry, civilian and military divisions of the federal government, states, and municipalities. The majority of these codes are related to either the American Society of Mechanical Engineers (A.S.M.E.) Boiler and Pressure Vessel Code or the Underwriters' Laboratories, Inc. Standards for Storage of Hazardous Liquids. Adamson is certified by the A.S.M.E. for production of fired and unfired pressure vessels and boilers; and by the Underwriters Laboratories, Inc. for production of tanks containing hazardous liquids. Adamson is also qualified to produce tanks to other exacting specifications and can qualify for additional special codes as required. In addition to manufacturing tanks from steel, Adamson will design and fabricate, to desired requirements and specifications, al types of storage tanks and pressure tanks constructed of Cu-alloy, stainless or other types of corrosion resistant material when requirements warrant their use.

A.S.M.E. Tanks

The American Society of Mechanical Engineers (A.S.M.E.) has established rules governing the design, construction, labeling, inspection, and installation of pressure tanks. The A.S.M.E. code symbol is your assurance that a tank strictly conforms to all applicable A.S.M.E. specifications. A Manufacturer's Data Report (certificate of inspection) must be verified by an authorized independent inspection agency and must be supplied with each A.S.M.E. stamped tank.

PAINTING AND LINING

Painting

Adamson can supply tanks painted in accordance with virtually any industrial, military, or civilian painting specification. All Adamson tanks, unless protection is otherwise specified, receive an industrial shop coat prior to shipment.

Galvanizing

Galvanizing has been used as a corrosion deterrent for steel water tanks for many years and has given satisfactory results in thousands of cold water installations. Although the protection cannot be considered as permanent as that of cement or epoxy lining, and is not suitable for extended operation much in excess of 100 F, galvanizing does extend that tank life considerably at a reasonable cost.

Dura-Flex-Cement Lining

Cement lining is applied to the interior of steel pressure vessels to provide protection against corrosion. The Adamson Dura-Flex cement lining is designed to develop a high strength bond between the tank and the lining and to safely withstand handling during shipment and installation. The lining imparts no odor or taste to water and will withstand temperatures up to 212 F.

Epoxy

Epoxy linings are one of the modern alternatives to glass lining and phenolic lining. They have been widely accepted and have provided excellent results in eliminating corrosion in steel vessels containing water or other liquids.

Dura-Coat

This is a two part system consisting of Dura-flex undercoat covered with a solvent free two-component heavily cross-linked polymerized topcoat which will provide a hard, durable, nontoxic inert finish. This coating conforms to AWWA, USDA, FDA and, if required, NSF standards for potable water and is unaffected at temperatures up to 200 F (tested at 73.4 F for NSF).

Copper-Lining

These tanks are constructed so that the tank contents contact only non-ferrous surfaces. To accomplish this, the 3# per square foot sheet copper lining is electrically welded to the steel tank at every seam of the lining and at every connection and opening. Every connection and opening is electrically welded to the outer steel shell. Thus, the lining is strongly and permanently attached to the outer reinforcing shell, the surface of which is completely sealed off from corrosion forming air and water. The result is a copper tank constructed inside of, and reinforced by a steel outer tank effectively giving a double walled construction. An inspection opening is provided to monitor the interstitial space and detect any leak in the inner copper shell without removing the vessel from service. All threaded connections are of extra heavy solid copper nickel material. The neck portions of all flanged nozzles and element necks are constructed of solid copper nickel; these are welded to steel flanges in such a way that gasket surfaces are also of copper nickel. The manhole ring is copper-lined and the cover is solid copper nickel. All tube-sheets, spacers and supports of elements are of solid bronze. Both hydrostatic and pneumatic tests are performed to make doubly sure there are no leaks in the lining. For storage heaters, the element, the lining and the steel tank are tested independently of each other, to prevent possibility of "hidden" leaks in either the element or the lining.

Urethane

This is a two component, instant setting polyurethane developed to protect potable water tanks. It will not impart any taste to the contents of the tank and is approved for contact with potable water by various authorities. Urethane can only be applied to tanks 60" in diameter and larger with no internal trim.

Supports

A complete line of Adamson welded steel supports is available. The three most commonly used pressure vessel supports are: angle legs or base rings for vertical tanks and saddles for horizontal tanks. Saddles can be supplied with threaded bosses for pipe legs.
