  • Austenitic stainless steels have high ductility, low yield stress and relatively high ultimate tensile strength, when compare to a typical carbon steel. A carbon steel on cooling transforms from Austenite to a mixture of ferrite and cementite. With austenitic stainless steel, the high chrome and nickel content suppress this transformation keeping the material fully austenite on cooling (The Nickel

  • Overview of Hydrostatic Testing Hydrostatic (Hydro) Testingis a process where components such aspipingsystems, gas cylinders, boilers, andpressure vesselsare tested for strength and leaks. Hydro tests are often required after shutdowns and repairs in order to validate that equipment will operate under desired conditions once returned to service. Furthermore, hydrostatic

  • Preheat in Welding: What Is It and When Should You Use It? Preheating in welding is used to help ensure weld quality and reduce the occurrence of cracking and other problems that can result in costly rework. Welding preheat is commonly used before welding steel or steel alloy pipes or plates that are 1 inch thick or more. Preheating is often required in shop and field welding for oil and

  • The Vessel Pressure Testing article provides you with information about pressure vessel hydro-static testing requirements and related item in pressure vessel inspection. The requirements have been described based on ASME Code Section VIII. You need to do this test after completion of the construction process, but before the internal parts assembly and also before painting process. This content

  • Once you have determined that the welding application requires preheating, consider the best method to use. Induction heating is one preheat option that provides consistent heat throughout the weldment. It offers fast time-to-temperature and is considered a very safe option for preheating.

  • Basic Weld Inspection - Part 2 John Hoh Senior Staff Engineer National Board Category: Design/Fabrication Summary:This article was originally published in the Winter 2010 National BoardBULLETINas the second of a two-part series. This is a continuation of the articleBasic Weld Inspection - Part 1originally published in the Fall 2009 edition of theBULLETIN,

  • Welding processes can introduce contaminants and metallurgical defects into a component. Applied Technical Services offers NDT welding inspection on structures, both ferrous and non-ferrous, or components to detect surface and sub-surface defects and discontinuities. In order to meet quality and safety standards, welds are commonly required to withstand load and stress conditions.

  • Preheating is the act of heating the base metal before starting to weld. It is considered very essential in high thickness materials, Cr-Mo Steels & HSLA High Speed Low Alloy steels, etc… Here we are going to answer the below topics What is Preheating ? Why is Preheat Essential ? What is difference between Preheat, interpass temperature and Post weld heat treatment? How

  • Have you heard of post weld heat treatment (PWHT)? Of course you have. If you are involved in welding you have definitely heard this term. But what is PHWT? When is PWHT required? What temperature should PWHT be done at? Heat treating of materials can be a very complicated subject, but when it comes to heat treatment after welding it boils down to a simple concept: PWHT is done in

  • Q: We are expanding our job shop and adding the capability to work with much heavier structures, including considerably thicker materials. Some of these jobs specify high-strength materials and preheating. Some of our welders claim preheating is performed to remove water from the steel. Can you expand on this? A: This is an excellent topic for discussion! Preheating and postweld stress relief are

  • Construction Codes & Significance Postweld heat treatment on the weld of ASTM A335 P11 seamless pipes. The heat treatment is performed by a flexible ceramic pad heater. Seamless pipes made of low-alloy steel ASTM A335 Grade P11 can be used for power piping (ASME B31.1) or process piping (ASME B31.3) at elevated temperatures. After joining the two ASTM A335 P11 pipes together by a welding

  • PIPING HYDROSTATIC TESTING (OVERVIEW) Pressure source and test gauge should be upstream of check valve. If pressure source is downstream, check valve should have flapper removed or jacked?up. (Pressure must be released downstream of check valve after test completion.) Ensure that test blinds installed are the Correct thickness. Ensure that all items such as control valves, relief valves,

  • Radiographic Testing (RT)is anondestructive examination (NDE)technique that involves the use of either x-rays or gamma rays to view the internal structure of a component. In the petrochemical industry, RT is often used to inspect machinery, such aspressure vesselsand valves, to detect for flaws. RT is also used to inspect weld repairs. Compared to other NDE techniques,

  • Preheating Heat treatment of welds is a critical activity which needs to be carried out before and after the welding process. Heat treatment before welding (Preheating) is necessary to bring the base weld metal at proper temperature. No welding shall be performed without preheating the joint to 10°C (50°F) when the ambient temperature is below 10° C. Preheating requirements for

  • We all have probably heard about destructive testing in welding. After all, those of us who are certified welders or work at a place that needs to certify welding procedures, have at one time or another heard about a bend test, or a charpy v-notch test. However, there are several types of non-destructive testing available. As you can imagine, performing destructive testing on
