Heat Exchanger: EN ISO 16812 in comparison with API STD 660
EN ISO 16812 and API STD 660, both standards specifies requirements and gives recommendations for the mechanical design, material selection, fabrication, inspection, testing, and preparation for shipment of shell-and-tube heat exchangers for the petroleum, petrochemical, and natural gas industries and is applicable to the following types of shell-and-tube heat exchangers: heaters, condensers, coolers, and reboilers. […]
Hazard identification and the PED risk assessment process
This Pressure Equipment Directive (PED) should harmonise national provisions on risks due to pressure. The other hazards that may arise from this pressure equipment may fall within the scope of other EU Directives (e.g. Machinery, Low Voltage, Explosive Atmospheres) that deal with these hazards. Pressure equipment subject to a pressure of not more than 0,5 […]
TEMA Heat Exchanger Types
TEMA® is a trade association of the world’s leading manufacturers of shell and tube heat exchangers. TEMA has developed standards that define the design, fabrication, tolerances, installation and maintenance of shell-and-tube type heat exchangers. The TEMA standard defines the main configuration of exchangers and the classification for usage in the industry. This standard and the […]
PED hazards analysis and risk analysis
Essential requirements must be applied as a function of the hazard inherent to a pressure equipment. Therefore, pressure equipment manufacturers have to carry out a risk analysis to first identify all possible risks that the pressure equipment may pose and determine the essential requirements applicable to the pressure equipment. This analysis has to be documented […]
Advantages of Rupture Disc in combination with Pressure Relief Valve
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 to allow for the release of overpressure and to reclose when the pressure returns back […]
Piping Codes suitable for PED applications?
The European piping code is the harmonised standard EN 13480 series, the application of which is assumed to comply with the essential safety requirements (ESR) in accordance with Annex I of the PED (presumption of conformity).
Hydrogen compatibility of materials in hydrogen gas applications
The compatibility of the material of pressure vessels, pipelines and their components used in the production, storage and transport of hydrogen is of great importance for safety and long-term use. Therefore, manufacturers of pressure equipment, pipework and other components must carefully select the materials, taking into account the existing operating conditions such as temperature and […]
ASME Code Cases – How to use?
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 by any user.
What is the ASME definition of MAWP?
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 be indicate in the manufacturer’s data report.
