  • Welding Procedures are the guidelines used to perform a weld. They are designed to provide a record of the welding variables used and the inspection results obtained during the procedure qualification test. They can also provide the instructions for the welder to use in production in order to produce acceptable welds. Usually welding procedures are developed in accordance with a welding code or standard,

  • 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

  • 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

  • Preheating involves heating the base metal, either in its entirety or just the region surrounding the joint, to a specific desired temperature, called the preheat temperature, prior to welding. Heating may be continued during the welding process, but frequently the heat from welding is sufficient to maintain the desired temperature without a continuation of the external heat source. The interpass temperature,

  • All ASME Code Stamped Section VIIIpressure vesselsmust undergo a pressure test.Cryogenic pressure vesselswith Code Stamps are no different. The requirements for this pressure testing is contained within paragraphs “UG-99 Hydrostatic Pressure Test”, “UG-100 Pneumatic Test”, and “UG-101 Proof Tests to Establish Maximum Allowable Working Pressure”.

  • Ensuring a topnotch weld inspection program​ Ensuring that welders follow specific procedures is a crucial step in the overall welding quality system. There are a number of reasons to inspect a weld, the most fundamental of which is to determine whether its quality is good enough for its intended application. To evaluate the quality of a weld, it is necessary to

  • 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

  • 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

  • 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.

  • Many characteristics of a weld can be evaluated during welding inspection - some relating to weld size, and others relating to the presence of weld discontinuities. The size of a weld can be extremely important, as it often relates directly to the weld's strength and performance. For instance, undersized welds may not withstand stresses applied during service. Depending on their size and/or

  • 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

  • We provided the inspection activities for the duvha power plant boiler explosion situation. the inspection activities includefit-up inspection, welding inspection, dimension inspection, pre-installation inspection and installation inspection as well. The procurement process followed the requirements of the Preferential Procurement Policy Framework Act (PPPFA) and the qualifying supplier was

  • 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

  • We provide services as individualsto the project for the inspection of welding including fit-up inspection, weld visual inspection, line alignment inspection, dimension inspection of the modules. weld visual inspection of steel structure, preheat inspection, PWHT inspection, hydro test inspection, final walk down, punch list preparation, final dossier review.

  • 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,
