This article provides for evaluating the WN flange loads, taking into account the internal pressure together with the external loads (forces and bending moments) acting on the WN flange. The loads exerted on the flange that are included in the …
Compatible hydrogen piping steel is coming into focus in the context of the increasing importance of hydrogen for energy applications, particularly with regard to hydrogen embrittlement (HE). Carbon steels with higher strengths are increasingly coming into focus for the storage …
Both Rupture Discs (also called bursting discs) and Pressure Relief Valves (PRVs) may be used independently as source of pressure relief. Rupture discs are pressure relief devices intended to burst once the intended burst pressure is reached. PRVs are designed …
ASME Code Cases are approved exceptions or alternatives to code rules. They include specific requirements that, when fully and correctly implemented, help users achieve continued quality and safety. Code Cases are not mandatory but may be used for Code compliance …
The maximum allowable working pressure MAWP is a very important therm in the ASME BPVC and therefore essential for construction safety. The ASME BPVC requires, that the manufacturer specify the MAWP on the nameplate of the pressure vessel and should …
The maximum allowable working pressure MAWP is a very important therm in the ASME BPVC and therefore essential for construction safety. Note: The MAWP is not defined in the PED.

This article provides an overview of duplex material specifications for pressure equipment applications. Compared with some other materials, Standard Duplex Steels and Super Duplex Stainless Steel are less costly material of construction offering high mechanical strength, good weldability, good toughness …
Stress corrosion cracking (SCC) is characterized by cracks propagating either transgranularly or intergranularly (along grain boundaries). Chlorides are widely present in many industrial and natural environments, such as seawater. When metal alloys are exposed to these environments, they can become …
The PREN (Pitting Resistance Equivalent Number) for duplex steels is an important parameter for classifying duplex steels also from the point of view of corrosion resistance, such as chloride stress corrosion cracking (SCC).
