This paper describes the Creep Amendments which will be implemented in EN 13445, the European Standard for Unfired Pressure Vessels, in 2007. It will address four topics: 1) Specifications for Materials and Weldments. 2) Specifications for Design By Formula and Damage Accumulation rules. 3) Specifications for Design By Analysis — Direct Route (Creep Rupture, Excessive Creep Strain, Creep and cyclic Fatigue Interaction). 4) Specifications for Inspection and Non-Destructive Testing (NDT).

This paper discusses the non destructive testing (NDT) of unfired pressure vessels made of ductile and tough steels, as contained in Part 5 of the European standard EN 13445:2002. The concept and use of testing groups along with “satisfactory experience” in welding are presented. Also the background and rationale for the determination of standards used for NDT methods, characterisation and acceptance criteria are discussed in detail. Benefits for the pressure equipment industry are emphasised.

Industry must have good quality for their services or products. One of the things that their have done is how to get the customer’s belief in their brand. Quality in every part has become the main case. Most of the companies in industry use metals as material to support their services. When the goods have been processed, it must continue with the testing. This is to prove that the goods have gone through the formation process fill in standard quality which required by the customer. There are two types of testing known as destructive testing and non-destructive testing. There are some of ways of non destructive testing methods on metals inspection has been applied in testing the quality of goods. Such as visual test, magnetic particle test, liquid penetrant, eddy current test, ultrasonic test, radiographic test in metals testing. Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. Radiographic Testing (RT) is a nondestructive examination technique that involves the use of either x-rays or gamma rays to view the internal structure of a component. In the petrochemical industry, Radiographic Testing is often used to inspect machinery, such as pressure vessels and valves, to detect for flaws. RT is also used to inspect weld repairs. Compared to other NDT techniques, radiography has several advantages. It is highly reproducible, can be used on a variety of materials, and the data gathered can be stored for later analysis.

This paper deals with non destructive testing (NDT) and inspection of cyclically-loaded unfired pressure vessels designed to EN 13445. It details specific provisions contained in Annex G of EN 13445-5 for shape imperfections and areas identified in the fatigue analysis that can limit the lifetime of the vessel (referred to as fatigue critical areas).

This paper addresses a methodology to maintain pressure vessels per ASME Section VIII, Division 1 Code and jurisdictional requirements, for new and existing pressure vessels. The pressure vessels discussed are drums, towers, shell & tube heat exchangers, and air-cooled exchangers, all designed and built per ASME Section VIII, Division 1. The methodology applies to vessels in refineries, gas plants, oilfield facilities, and chemical plants. Vessel adequacy is maintained via Codes, non-destructive testing, materials, inspection, company standards, welding procedures, inspection/maintenance standards, and jurisdictional requirements. Unique maintenance software, “PVCalc”, can aid in vessel calculations, to calculate the pressure rating, and remaining life, per the original edition of the Code under which the vessel was built. New vessel designs should be thoroughly reviewed, as the author’s experience over the last eight years is that approximately 65 to 80 percent of all vessel designs contain design errors (mostly minor) per ASME Code.
