Types of Plate Heat Exchangers

Typical applications of plate heat exchangers include Oil Cooling, HVAC, Food & Beverage, Petrochemical plants, Power, Pharmaceutical, Dairy, Marine, etc. Due to their large surface area, plate Heat Exchangers have a high heat transfer rate compared to other types of heat exchangers. They are made of a set of composed thin metal plates called ‘plate […]

Dimple Jacket Pressure Drop

Pressure drop through dimple jacket depends on various factors: Cooling/heating medium and its physical properties Dimple jacket and vessel material Plug dimension and arrangement Temperature Length of travel Flow rate and many more. To obtain a unique equation or method of calculation of pressure drop is almost impossible as it takes a lot of computational […]

How to Do Burst Test per UG-101(m)

The maximum allowable working pressure for vessels or vessel parts for which the strength cannot be computed can be established by burst testing in accordance with ASME VIII-1 UG-101(a)(1), or through Finite Element Analysis (FEA) in accordance with ASME VIII-2. Burst testing and FEA may only be used for the purpose of establishing a maximum […]

WRC 107 vs WRC 537

When it comes to attachments to pressure vessels, process piping and attached structural and lifting clips exert external loads on pressure containing parts. This must be considered for further investigation as per ASME VIII-1, UG-22. One of the confusing subjects in designing pressure vessels and attachments is whether to use WRC 107 or WRC 537, as […]

Unlisted Materials

To register a fitting or equipment for CRN, the material of construction has to conform to the applicable codes and standards. Allowable materials are listed within the codes and standards in which the design is registered to. The design could be based on either code calculation, Finite element Analysis (FEA) or proof testing. For each, […]
