Gas Metal Arc Welding (GMAW) is commonly used for welding alloys, such as stainless steel and aluminum, or any work involving brazing, fabrication or pipework. How GMAW Works The electrode in GMAW consists of a roll of wire that is fed into the work piece by a ‘gun’. The rolled wire electrode allows for the Keep reading…
Thermal fatigue cracking is a potentially dangerous condition that occurs as a result of cyclical expansion and contraction caused by temperature variations in industrial process equipment. The extent of damage will depend on the frequency and magnitude of these temperature swings. Damage from thermal fatigue manifests itself in the form of cracking in the equipment Keep reading…
Shielded Metal Arc Welding (SMAW), or ‘stick welding’ as it’s sometimes called, is one of the most common welding methods used in modern industrial fabrication processes. SMAW involves an electrode, usually a metal rod or stick, clamped to a welding torch to create an electric arc.The high temperature of the arc melts both the electrode Keep reading…
Non-destructive testing (NDT) is widely used for quality control in the fabrication of process plant and equipment. It is a set of techniques used to evaluate the structural integrity of materials and detect any flaws that can compromise their safety or functionality. Here are five of the most common NDT methods in use today. Liquid Keep reading…
A dirty boiler tube is an inefficient boiler tube. While some degree of soot build-up is inevitable in any boiler system, excessive soot may indicate serious furnace or fuel issues that result in dramatic decreases in efficiency. In firetube boilers, hot gases flow through tubes carrying the byproducts of combustion. Over time, these accumulate to Keep reading…
Improper selection of material is one of the leading causes of failure in pressure vessel. As a result, choosing the appropriate metal for a specific tank application is of the utmost importance. Choosing the wrong material can lead to any number of issues, from poor performance and lower efficiency, to catastrophic failure and reduced safety. Keep reading…
Exhaust gases produced from industrial processes often contain substances that are harmful to the environment. Because of this, facilities are required to take measures to remove pollutants before gases can be released into the atmosphere. Wet and dry industrial scrubbers are two of the most effective pollution removal technologies. Here is a brief overview of Keep reading…
Forced circulation evaporators are important pieces of equipment used in process industry to remove water from liquids. When it comes to which type of evaporator to use for a specific application, operators have a number of different options to choose from. The use of forced circulation evaporators are common in operations where feed viscosity is Keep reading…
Pressure vessels, such as industrial boilers, can be sensitive to a variety of scaling and heat loss issues if they are not properly maintained. Follow the five preventative maintenance tips below to ensure that your boiler remains safe, efficient, and reliable. Clean Your Boiler Periodically Scale, soot and other forms of residue can cover the Keep reading…
There are many causes of weld defects in pressure vessels. In this blog, we focus on the three most common causes. Moisture on the Weld Surface Porosity is one of the most common defects caused by the presence of moisture on the weld surface. It occurs when gas gets trapped in the molten pool, resulting Keep reading…
