As the largest cold-form head manufacturer in North America, we’ve built a reputation for high-quality workmanship that has our customers coming back to us for every project:
Brighton Tru-Edge gets its name from the precision machined bevels we produce on every tank and vessel head. This precision edge provides for higher speed and accuracy in your final tank assembly and welding.
Our industry-exclusive equipment makes it possible for us to machine the beveled head efficiently and cost-effectively.
Tru-Edges make for a faster fit-up and final assembly, which means you save time and money during the manufacturing process. And, this is just one of the value-added methods that are standard for Brighton Tru-Edge heads, delivering superior quality and performance for our customers.
The corrosion-resistance of stainless steel makes it an attractive selection for many tank and vessel head applications. At Brighton Tru-Edge, we maximize our customers’ benefits associated with these properties by completing nearly every stainless steel head with a pickling process.
In normal atmospheric conditions, ordinary stainless steel will not rust. It has a protective layer that forms when the steel surface reacts with oxygen. However, during the manufacturing process, a head may be exposed to acids or other conditions that might interfere with this layer. Pickling removes specific surface defects and contaminants and restores the common corrosion resistance of the stainless steel.
After forming, we completely submerge Brighton Tru-Edge heads in our heated 25-foot tank. We utilize a picking solution of nitric acid and ammonium bifluoride. After pickling, we spray the heads with a high-temperature steam cleaner. This pickling process extends the life of the materials, enhancing the longevity of your equipment.
At Brighton Tru-Edge, we can offer pickling on a wide variety of end products. We provide pickling services for all fabricated stainless steel, including half-pipe, coils, and cylinders, to meet your needs. We can also offer our pickling services for stainless products you have manufactured or produced elsewhere.
Brighton Tru-Edge manufacturers the highest quality polished heads in the industry. We can achieve a near mirror finish or produce a standard uniform finish, depending on our customers’ specifications. Our experienced team utilizes best-in-class equipment to spin polish heads as large as 252″ in diameter. A tracking mechanism follows the contour of the head for a smooth transition from the dish radius into the knuckle portion of the head.
Pressing a head in a cold-forming manufacturing plant takes a unique combination of experience and skill. No two metal plates react the same way to the forming process. Our operators combine decades of experience with keen observation, attention to detail, and skill to ensure the head radius, depth, and other specifications are exact.
Not every operator can master these skills, and only the best deliver this service to Brighton Tru-Edge customers. Even presses with the latest technology to capture pressing standards require operator discretion to achieve exceptional results.
At Brighton Tru-Edge, we utilize proprietary equipment to deliver the best flange and machine bevel for every manufactured head. With our industry-leading technology, our operators can achieve specifications to the tightest tolerances, which saves you time and money in the assembly process by creating a good fit-up during welding.
At Brighton Tru-Edge, we offer heat treatments in our oversized furnace to meet customers’ code requirements and needs. We utilize thermocouples attached to the heads to ensure proper heating of the material. Our computer-controlled furnaces are programmed for the specific needs of a piece to complete a heat treatment cycle. We then document the treatment on a heat chart.
We perform this treatment on material above the critical transformation temperature when required, either in the flat or after forming. For SA-516-70, we utilize a normalizing cycle of 1650F +/-50 for a half-hour per inch of thickness, thus refining the grain structure of the material.
We perform this heat treatment to relieve work hardening stresses in the material. On cold-formed heads, the ASME requires some heads to be stress relieved when the fiber elongation exceeds 5 percent.
Stress relieving of SA-516-70 requires a controlled heating and cooling process, as detailed in UCS-56. We maintain the material’s temperature at 1,100 degrees Fahrenheit for one hour per inch of thickness. ASME Section VIII, Division I, UCS-79 (d) does provide for some exemptions.
This method of heating stainless and nickel alloys dissolves carbide. It is cooled at a fast enough rate to prevent the carbon from producing additional carbides, freezing the carbon in solution. This method is used to increase ductility and corrosive-resistant properties. We utilize solution anneals at 1950 degrees Fahrenheit +/-50 degrees, followed by water quenching for SA240 304/304L and SA240 316/316L.
