Because the Halvorsen Company has developed high-quality control systems for the manufacture, fabrication and assembly of ASME code compliant pressure vessels that conform to, or exceed, industry standards, we are not usually the lowest bidder for a pressure vessel manufacturing contract. When it comes to manufacturing pressure vessels, quality workmanship, technical standards and safety take precedence over the lowest price and cheapest rates. We utilize cost-effective pressure vessel manufacturing techniques that minimize our labor rates and operating costs. The pressure vessel design software we use provides outstanding fabrication productivity and safer design features.

The prices and fees we charge for pressure vessel manufacturing services are competitive with other pressure vessel manufacturing companies located in the United States. Our services include the design, engineering, manufacturing, construction, fabricating, assembly, calibration, non-destructive examination, metallurgical evaluation, dimensional inspections, testing and delivery of pressure vessels, tanks, AOD (A.O.D/A-O-D) vessels, converter vessels, boilers and related components.

We specialize in fabricating custom industrial pressure vessels, stripper columns, pressure reactors, ASME separators, heat exchangers, process equipment, distillation towers, knockout drums, stripper towers, oil and gas pressure vessels, stainless steel cyclonic separation vessels, storage vessels for liquified gases, pressure vessels used as separators and pressure vessels for refineries made from carbon steel, stainless steel, low-alloy steel and high-alloy steel, ASME SA516 Grade 70 Carbon Steel Plate and other materials. Watch our video titled “Pressure Vessel Manufacturing” on YouTube. We are constantly challenging our engineers to achieve cost, performance and safety goals through the use of a best practices approach and the latest and newest industry steel pressure vessel design, engineering and manufacturing technologies. We can provide cost estimates for the complete project of manufacturing a pressure vessel and/or list prices for each step of the vessel manufacturing process.

Our clients have been contracting with Halvorsen to purchase heavy duty pressure vessels and our fabrication services for decades based on our engineering, design and manufacturing prowess. Click here for information on pressure vessel manufacturing and fabrication cost estimates, quotes, pricing, rates and expenses. Pressure vessels, pressurized storage tanks, industrial autoclaves, reaction vessels and industrial tanks can be dangerous to operate, so our customers rely on our designers and engineers to use the best construction materials and incorporate numerous safety features related to fatigue, fracture and leaking before bursting. During the pressure vessel design and engineering process, we often suggest to our clients features that can decrease the production cost while still maintaining quality standards. We manufacture pressure vessels use to store, manage and transport hazardous materials, chemicals,and biomass as well as pressure vessels that contain water, steam and radioactive waste. We have been manufacturing reliable boilers (pressure vessels) for the steam industry since 1955 that meet our customer’s tolerance requirements and are delivered and transported to our client’s plants and facilities on time and on budget. Pressure vessels are sometimes called tanks. We manufacture and assemble flash tanks, acid tanks, blow down tanks, ASME code tanks, ASME compliant tanks , compressed air tanks, mixing tanks, condensate tanks, filter tanks, separator tanks, cyclone tanks and expansion tanks. During some fabrication projects, our customers will request that we apply powder or chemical resistant coatings to the outside or inside of the tanks and pressure vessels that we engineer, design and manufacture. Per SSPC  (Society for Protective Coatings) standards, we blast with media that includes glass beads, sand and metal beading. Pressure vessels can be classified as Type I, Type II, Type III and Type IV. The Halvorsen Company primarily manufactures all metal and steel pressure vessels which are considered to by Type I. Pressure vessels can be manufactured in different shapes, including spheres, box, cylinders and cones. Most of our customers contract with us to manufacture cylindrical pressure vessel which incorporate a shell or cylinder and heads or end caps.

The Halvorsen Company uses a wide range of pressure vessel quality (PVQ) steel plate to fabricate, manufacture and produce welded pressure vessels, boilers and other high pressure applications. The materials we use include PVQ516 (Grades 55, 60, 65, 70), ASTM A516-70 Plate, A-36/SA-36, SA-516-70/SA-516-70N, SA-514/SA-517, A516/70 and C-1045. The PVQ steel plates that we use can be normalized or stress relieved. We use PVQ steel because it can possesses excellent welding capabilities. The Halvorsen Company fabricates boilers and pressure vessels and their accompanying forgings with pressure vessel quality steels that also exhibit outstanding notch toughness.

We build closed containers that are designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Halvorsen is a premier manufacturer and supplier of ASME code pressure vessels. We provide 100% radiographic testing and inspection (RT-1) services, spot radiographic testing and inspection (Spot RT) services, post weld heat treating (PWHT) services and also insulate pressure vessels. Some pressure vessels that we manufacture in Cleveland, Ohio are also furnished with platforms and ladders. We often install internal tray rings in the pressure vessels we fabricate. On type of pressure vessel we manufacture will induce a chemical reaction at high pressure. Another type of pressure vessel we construct causes flash evaporation occurs inside the pressure vessel, which is also called a flash drum.

Halvorsen fabricates pressure vessels in many different shapes, sizes, widths and lengths. We often weld sections of cylinders and cones. The most frequent request from our customers is for the custom manufacture of pressure vessels fabricated from cylinders that use 2 endcaps or heads. The most important thing at Halvorsen is that we ensure that the pressure vessels we manufacture will be operated safely. Our customers trust that we are experts at fabricating safe pressure vessels based on the design code called the ASME BOILER and Pressure Vessel Code.

We also handle the logistics for the safe delivery and transportation of the pressure vessels, settler vessels (pressure vessel separators),  knock-out pots (vapor–liquid separators), knock-out drums (vapor–liquid separators), refining vessels, stripper tower pressure vessels or stripper columns, flash drums (vapor–liquid separators) and liquified gas storage vessels and tanks that we manufacture for natural gas processors and other oil and gas companies that utilize and produce oil, gasoline, butane, ammonia, chlorine, LPG, propane and diesel fuels.
