Brief Introduction of Stress Corrosion Cracking Stress corrosion cracking or SCC is a slow failure mechanism of engineering materials in corrosive environments. Many ductile metals and alloys, when exposed to a corrosive environment, begin with crack initiation, propagation, and growth of that crack, and fail year after year due to stress corrosion cracking. Stress corrosion … Read more
What is Blowdown Valve? Blowdown valve in process engineering plants are a special type of pipeline valve with a wide range of applications. The main purpose of a blowdown valve in a plumbing or piping system is to initiate bleed when the valve is actuated. Drainage valves depressurize systems or equipment for maintenance or emergencies, … Read more
Hot bolting is a critical maintenance procedure widely employed in various industrial sectors, including oil refineries, petrochemical plants, and power plants. This technique involves the replacement of bolts within a flange connection while the pipeline or equipment remains operational, thus allowing continuous service without significant downtime. The focus of this article centers specifically on the … Read more
What is Cryogenic Piping? Cryogenic piping refers to piping networks that operate below -290°C. This temperature represents the embrittlement limit of carbon steel materials, but various references consider piping systems operating below -1500°C (-3000F) to be suitable cryogenic piping systems. Industrial processing and transportation of propane, butane (LPG), methane (LNG), ethylene, nitrogen, ammonia, and oxygen … Read more
Introduction A throttle valve is a type of valve that can start, stop, and regulate the flow of fluid from one point to another. Generally, there is a large pressure difference between the upstream and downstream sides of the throttle valve. As the throttle valve flow restriction increases, the pressure loss increases. Many control methods … Read more
Introduction of Accelerometer An accelerometer is an electromechanical device that measures the acceleration of movement of pipes, equipment, or structures. It is a very useful tool for vibration engineering and is often used for vibration measurements in industrial equipment. The force of vibration produces an electrical signal that is detected by an accelerometer sensor. Accelerometers … Read more
White rust is a localized corrosive attack on the zinc surface, appearing as a chalky substance as deposits. This is rapid corrosion and usually occurs when zinc is exposed to oxygen and hydrogen. White rust is also called storage white stain. White rust is often found on new galvanized steel products. These deposits degrade the … Read more
Pump Performance Curve A pump performance curve is a design analysis (or display) of a pump, how it performs in relation to changes in operating parameters such as pressure (head is derived from pressure) and flow. Operating parameter dependent factors are head, shut-off height, impeller diameter, efficiency, NPHSR, and power consumption. These terms are explained … Read more
Diffrent types of welding methods are used for welding stainless steel. We will discuss all the important welding methods of stainless steel. Let’s get brief idea about stainless steel. Stainless steel is a high carbon steel. It is widely used in the industrial sector due to its excellent corrosion resistance, elevated and cryogenic temperature properties. … Read more
A weld defect can be defined as an unacceptable defect during welding process. Unacceptable deviations in set technology and design called a weld defect. Weld defects can occur at any stage of the welding process,They are easily recognisable in the form of geometric errors. Such weld defects affects both inside and outside metal structures.Various codes … Read more
