Pressure Vessels and Tanks Solutions
C4 Welding is a trusted manufacturing partner for a wide range of large pressure vessels and tanks for holding storage, material processing, and heat exchange. We’ve been one of the leading pressure vessel fabricators for years, providing safe and reliable storage and handling vessels for many different applications.
The Types of Pressure Vessels and Tanks C4 Manufactures
Storage Tanks
Typically manufactured with carbon steel, storage tanks store liquids and gases under pressure for common utilities such as fuel oil, natural gas, and propane.
Heat Exchange Vessels
A very common type of pressure vessel is Heat Exchangers. These vessels are used for repeatable heating, chilling, or condensing functions.
Process Vessels
Specialized-designed drums, reactors, columns, or gravity separators are used to create a process in a controlled environment. These processes may be a desired chemical reaction, breaking down materials, or joining multiple products together.
Pressure Vessel Fabrication
The construction of a pressure vessel begins with customer-supplied engineered CAD drawings and a design concept that meets ASME (American Society of Mechanical Engineering) Boiler and Pressure Vessel code requirements. Our skilled process engineers use world-class CAD and CAM system software to determine the best methods to build the design. C4’s early involvement in the design phase can significantly reduce the time and cost of the initial development of a new design.
Pressure Vessel Welding Processes
When fabricating a pressure vessel, the C4 team combines various pieces with different welding processes.
Submerged Arc Welding (SAW) is characterized by using a continuously fed solid wire electrode that provides an arc totally covered by a layer of granular flux. SAW’s biggest advantage is its high deposition rate. It can typically deposit weld metal more efficiently than any of the more common processes.
Gas Tungsten Arc Welding (GTAW) is a versatile welding process that provides the highest quality weld using a non-consumable tungsten electrode. This method is mostly used for precise, small welds on stainless steel and other materials like aluminum, magnesium, and copper alloy.
Gas Metal Arc Welding (GMAW) or “MIG” welding is another popular process. It is characterized by a solid wire electrode fed continuously through a welding gun. An arc is created between this wire and the workpiece to heat and melt the base and filler materials. Once molten, the wire is deposited in the weld joint. We use MIG/GMAW and TIG/GTAW with a Sub-Arc Welding approach when fabricating pressure vessels.
C4’s welding team is certified and cross-trained for over 300 different in-house welding codes and processes and has experience welding stainless steel, carbon steel, titanium, and many other unique metals and alloys.
Testing and Inspection
Our pressure vessels undergo rigorous testing and inspection to meet ASME (American Society for Mechanical Engineering), ANSI (American National Standards Institute), and ASTM (American Society for Testing and Materials) standards.
Depending on the methods used to manufacture and weld the vessel, it may need to pass inspections such as X-ray, ultrasonic, visual testing, magnetic particle testing, dye penetrant testing, and a hydro test. These practices are critical to the safety and quality of the vessel’s end users. C4 has CWIs on staff with ASNT and NDT certifications to ensure all inspection requirements are met.
Pressure Vessel Fabricators for a Variety of Industries
C4’s pressure vessels are used throughout many industries, including Food & Beverage, Chemical, Pharmaceutical, Plastics, Oil and Gas applications. While they may seem different, all of these industries require pressure vessels to ensure the safety and proper regulation of sensitive materials. For instance, the Food & Beverage industry relies on pressure vessels for various reasons, including food processing, mixing, and sanitation. The Oil & Gas industry utilizes pressure vessels for various purposes, such as separators, scrubbers, drums, knock-outs, towers, treaters, and filters, just to name a few. In the pharmaceutical industry, tanks and pressure vessels are used for research and development and aid in creating pharmaceutical drugs that maintain US FDA regulations. Pressure vessels can also be used to produce plastics, chemicals, and more.
