We offer a variety of tube plugs for use in heat exchangers and boilers to keep them up and running. Whether it’s mechanical tube plugs or one-piece plugs, our products are made with quality materials so they are durable and can withstand different pressure requirements.
When needing to use and install mechanical tube plugs, having the correct tools for the job can make it easier and quicker to get the job. Below are step by step instructions to help overcome this challenge.
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.
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.
There have been many variations of the tube plug over the years in an effort to achieve maximum sealing area and to control the method in which it is installed. While each of these plugs are still commonly used today, they were designed to overcome various challenges operators have had over the years.
Not having a compatible tube plug material can result in leaks, costing hundreds of thousands of dollars or more in lost production and revenue. When plugging a “leaker” (leaking tube), it is good practice to use plugs that are the same or a compatible material to the tube in order to meet industry requirements and engineer specifications and avoid galvanic corrosion.
