  • One of the most common uses of nondestructive testing (NDT) is the examination of weld integrity. This is because welds are extraordinarily common in critical industrial applications across the world. The ability to inspect welds nondestructively is essential, as destroying one for testing necessitates replacing it with a new, untested weld. As such, there has been significant technological development

  • 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

  • Weldingis an essential part of operating and maintaining assets in the petroleum (upstream, midstream, downstream) and chemical processing industries. While it has many useful applications, the welding process can inadvertently weaken equipment by imparting residual stresses into a material, leading to reduced material properties. In order to ensure the material strength of a part is retained

  • 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

  • The descriptive term provides an important clue, so we're ready to take a guess at the role this test technique plays. Being engineers, however, there's no room for guessing, so let's get the explanations down in black-and-white right now. Hydrostatic testing, as utilized on a pressure vessel, uses water as a seal inspection medium. It is Technically a Non-Destructive Test Technique Pressurized

  • APRIL 7, 2017Featured Stories Transmission pipeline welding often requires preheating of the weld zone to ensure that the joint achieves its required strength and hardness. Proper preheating also helps minimize the risk of delayed hydrogen-induced cracking, which is a significant concern that impacts weld quality and integrity in transmission pipelines. There are several heating methods

  • 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.

  • To ensure the satisfactory performance of a welded structure, the quality of the welds must be determined by adequate testing procedures. Therefore, they are proof tested under conditions that are the same or more severe than those encountered by the welded structures in the field. This page contains visual inspection tips. The following pages contain inspection methods for GMAW and physical weld

  • PostHeating In case of alloy steel materials such as Cr-Mo stels, if the post weld heat treatment is not performed immediately after welding, then the weld joint and adjacent portion of pipe, at least 50 mm on either side of pipe, shall be uniformly heated to 300°C. This temperature shall be maintained for half an hour minimum, and then wrapped with mineral wool before allowing it to cool

  • The major objective of radiographic testing of castings is the disclosure of defects that adversely affect the strength of the product. Castings are a product form that often receive radiographic inspection since many of the defects produced by the casting process are volumetric in nature, and are thus relatively easy to detect with this method. These discontinuities of course, are related to casting

  • 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

  • Art of extracting maximum information from radiography image. This requires subjective judgment of the interpreter Interpretis to give the meaning of to explain.Evaluateis to determine the worth of something.Indicationis a density change appearing on a radiograph.False indicationsare film artifacts, screen Problems, fog, scatter x-ray diffraction.Discontinuityis

  • 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
