What’s The Deal With SA-105?


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.

The Evolution Of The Tube Plug


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.

Selecting The Correct Tube Plug Material


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.

Why Vent Tubes?


One of the most overlooked best practices for plugging a tube is to vent the tube beforehand. Tube venting is a process by which a small puncture is made inside of the tube, releasing any pressure or chemicals that may be trapped inside.
