Training programs can benefit to all organizations, especially, those in competitive markets. From improving operator retention, boosting productivity, and cutting job costs, training is a great investment to ensure your staff is up to date on all the latest industry practices.
Welding has become fairly common practice in pressure vessel fabrication and maintenance. From tube ends to plugs, welding can provide additional strength or sealing coverage if done correctly. When it comes to tube plugging, many customers are facing questions about plug materials and special requirements to ensure vessel specifications are met. In this article we will discuss the changes to the ASME code, material types and nomenclature, and impacts to the welding process.
Plugging tubes are one of the most convenient ways to repair shell-and-tube types of heat exchangers. It can be an effective and reliable method to fix a heat exchanger when done properly. However, it could cause more harm than good if not executed carefully.
Standards and processes are at the core of every business. From internal operating procedures to federal regulations, there are many different types of standards a company must follow in order to be successful. Therefore, it’s important to know how to identify what standards impact your business and how to adopt them.
Similar to a shell and tube heat exchanger, air coolers are made up of stacked finned tubes with header or water boxes on either end of the vessel. While air cooler maintenance can be challenging, there are a few tips and tricks that can help make the process easier.
Elliott Announces A Faster Way To Expand Small Heat Exchanger Tubes New and improved design expands tubes faster than any Elliott expander before, now at a [...]
Enhanced surface tubing has grown in popularity in recent years, with many different styles and options available. While enhancements are preferred for efficiency, they can pose some challenges to operators. As a result, it’s important to be aware of best practices before working with enhanced tubes to ensure that the job is done efficiently and without any damage.
Alfa Laval ACE, located in Broken Arrow, OK, specializes in heat transfer, separation, and fluid handling technology. With a focus on producing quality air coolers for their customers, rolling consistency was of utmost importance. With their current tube rolling method relying heavily on operator feel to regulate the amount of wall reduction, the accuracy of wall reduction was lower than desired. This resulted in too much time spent re-rolling tubes.
Contractors and maintenance personnel agree, the current method of tube cleaning using a rotary flexible cable to clean chillers is a hassle. The cable is problematic; it breaks, the feeding mechanism jams, and the feeder needs frequent and costly repairs. Substantial downtime is encountered to repair cables and units.
There are two motor power sources that are used for expanding tubes mechanically: electric rolling motors and pneumatic rolling motors. Determining what motor to use for a job will depend on operator preference, availability of electricity or air, and the application.
