Last Articles PN-Flange p/T- rating calculator Austenitic + Ferritic-Austenitic Steels This flange rating calculator contains p/T ratings of frequently used austenitic and ferritic-austenitic materials. It is based on Annex G of the harmonised standard EN 1092-1. The temperature-dependent strength values …
Flange face damages such as scratches or other indentations oriented in a radial direction have a decisive influence on the tightness of the flange connection. The serrated finishes of flange faces either concentric or spiral, should be free of scratches …
The flange face surface finish has an influence on a safety and tight flange connection. For standard requirements, the design of the flange surface determines the required roughness. This is taken into account in the standards for flanges (see the …
The use of certified materials from other codes was and still is a major problem. This is partly due to historical reasons and other interests may play a major role here. Nevertheless, under certain conditions it is possible to use. …
The EN 10204 certificate types for pressurised parts is an essential safety requirements of PED to ensure that the material used conforms with the required specification. The standard is not limited to metallic products e.g. plates, bars, forging, casts), but …
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 …
The latest articles Carbon equivalents are used as a parameter for estimating weldability with regard to crack sensitivity, particularly in the heat affected zone. There are several formulae for describing the carbon equivalent, in which the individual alloy elements are …
The latest articles In addition to carbon, other alloying elements also favour cold cracking. Carbon equivalents are often determined to estimate the susceptibility to cracking. There are numerous formulae for describing the carbon equivalent, in which the individual alloying elements …
