Weld Procedure Qualification Tests


Rigorously administered codes and guidelines act as a driving force for weld procedure qualification tests. In truth, those qualification tests are methodically structured, which means there’s an entire framework of rules and regulations directing this critically important engineering vocation. Governed by procedural routines, by documented inspection programs and quality control systems, every applied weld becomes […]

In Service Inspection of Pressure Vessels: A Mandatory Requirement


A specific set of inspection procedures are employed when pressure vessels exit the manufacturing phase. They ensure the pressure vessel complies with certain design criteria, as determined by product-relevant commissioning guidelines. However, in service inspections are a little different. They’re mandatory, just like the post manufacturing examination, but they’re evaluating a more dynamic operational scenario. […]

Plant & Equipment Maintenance: Why This Process Should Be Carried Out By Companies


On-site engineers are well-versed in their craft. They repair and maintain equipment and generally keep that machinery in fine operational form. That’s a lot of responsibility, even if we’re talking about a smaller installation, not a massive chemical processing plant or an oil drilling rig. Still, aren’t there situations that absolutely demand the attentions of […]

Different Types of Welding Procedures


Engineering textbooks describe the welding process as a means of joining two or more metal surfaces together. To facilitate the bonds, the contact points on those metal parts are melted, then they fuse together as a seamless welded joint. This metal bonding technology has been around for some time. In that time, approximately thirty welding […]
