  • 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

  • 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

  • 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

  • Many different types of welding inspection exist to keep pipes and structures safe and secure. Countless building codes require strict adherence to project plan specifications and inspection guidelines, according to Weld Procedures. The American Weld Institute usually produces code for multiple story structures, while the American Petroleum Institute issues construction and inspection guidelines for

  • At the end of construction, and following commissioning tasks such as water flushing, water should always be present in petroleum processing equipment. Whenever this water may subsequently lead to an operational problem, or if equipment may be damaged, it is necessary to perform a drying-out operation. There are several different reasons for drying-out depending upon the type of equipment and

  • 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,

  • Hydrostatic test Ahydrostatic testis a way in whichpressure vesselssuch aspipelines,plumbing,gas cylinders,boilersand fuel tanks can be tested for strength and leaks. The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified

  • The procedure of Post Weld Heat Treatment projects is often recorded in a quality document beforehand. It lists the requirements that should be met for the relevant heat treatments and that will lead to a guaranteed result. Post Weld Heat Treatment (PWHT) is the international term for stress relief annealing: a heat treatment that is carried out – among other things – after welding work

  • Industrial Inspection Inspection 4 Industry LLC,Provides Global Industrial Inspection Services. The services covers shop inspection, site inspection and plant inspection. The articles are about different inspection field categories such as shop inspection, site inspection, and in-service inspection requirements. The articles present you applicable codes and standards. There will also

  • Why is preheat sometimes required before welding? Preheating the base material to be welded minimises the temperature difference between the material and the arc, slows the cooling rate in the weld area and reduces the risk of cracking. The need for preheat increases with steel thickness, weld restraint, the carbon/alloy content of the steel, and the diffusible hydrogen of the weld metal. Preheat

  • Post-weld heat treatment or PWHT is a controlled process that involves reheating the metal below its lower critical transformation temperature, following a welding process. The material is then held at the elevated temperature for a predetermined period of time to alleviate residual stresses, increase the strength, increase or decrease the hardness, and reduce the risk of cracking by microstructural

  • As anyone in the fabricating and welding business knows, process and part inspection is a critical component of a successful business. Build and weld a poor part will simply guarantee failure. Today, welding associations, such as the Canadian Welding Bureau, offer certification courses to help welders learn the ins and outs of proper inspection processes, but before taking the course, you should

  • 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
