ASME CODE AND PRESSURE VESSEL DESIGN
ASME codes are used for process equipment design such as pressure vessels and piping all over the world. ASME codes cover the design, construction, maintenance and alteration of pressure vessel.
ASME codes used for the design of pressure equipments are:
ASME Sec.VIII Div I for design of vessels, towers and exchangers
ASME Sec I and Sec IV for boilers and water heaters
ASME Sec B31.1, Sec B31.3 and Sec B31.5 for piping system design
ASME Sec B31.3 is also used for the design of pipe fittings
These codes follow design by rules which provide formulas to check the design is safe as per the corresponding ASME code.
For high pressure vessels and complicated configurations ASME Sec. VIII Div. 2 rules are used for design by analysis where in Finite Element Analysis (FEA) tools are used for detail Engineering.
PRESSURE VESSEL DESIGN TOOLS
Heads are formed steel plates for pressure vessels and heat exchangers. The Head Thickness calculation page is an example page to calculate the wall thickness of heads, ellipsoidal, torispherical, kloepper and korbbogen heads. Calculation codes are ASME, Dutch Rules and the EN Euronorm.
The Shell Thickness calculation page is to calculate the wall thickness of a cylinder, cone and sphere under internal pressure. The calculation does not take into account the extra stress around holes for nozzles and is therefore a basic strength calculation. Calculation codes are ASME, Dutch Rules and the EN Euronorm.
Material properties are necessary for

the strength calculations of components of pressure vessels.The material properties page on this website is only for reference and values can be taken when using the head and shell calculation pages.
Equations and Calculator to determine the wall thickness of a welded nozzle connection to a shell, head or a similar geometry. Nozzle design includes pipe with flanges and with hub forgings. Area replacement calculation as per UG-37 determines whether the nozzle requires Reinforcement Pad.
Code Case 2901 is mandatory from Edition 2019. New section added as UG-44(b). For nozzles with external forces and moments the effect of these loads on flanges to be encountered in design with the equation gives in Code Case 2901/UG-44(b). The equivalent pressure is calculated and to be

added with internal pressure while calculating flange rating.
Flanges are used on equipment for the nozzles and in piping systems. The flanges are bolted together with a gasket in between to prevent leackage. The dimensions of flanges as per ASME B16.5 can be calculated with this tool.
This page lists the pipe wall thickness of pipes per schedule according ASME B36.10.
Shell and tube heat exchangers are complex and more expensive than ordinary pressure vessels. Also the strength calculation is more difficult. Part of the design process includes the determination of the amount of tubes to be used in the heat exchanger. The number of tubes and the dimensions are required to execute the calculation for the tube sheet. The Tube Sheet Lay-out page facilitates the calculation of the amount of tubes. The calculation can be done for four (4) pitch patterns (how the tubes are laid out) and for ten (10) types of passes (tube compartments).
PROCEDURE TO OBTAIN AN ASME CERTIFICATE OF AUTHORIZATION AND THE ASME CERTIFICATION MARK
Select an ASME accredited Authorized Inspection Agency (AIA) and sign an Inspection Service Agreement with this agency.
Application to ASME
Payment of the ASME fees
Purchasing the necessary ASME Code Books and Standards
Preparing and implementing a Quality System according to the ASME Code
The Pre-Joint Review performed by the AIA (represented by the Authorized Inspector [AI] und Authorized Inspector Supervisor [AIS]) serves to review the Quality Control System and its implementation.
ASME Joint Review:
Piping Stress Analysis is a vital part of Piping Engineering. Stress analysis of piping to be done for analyzing the piping system for flexibility against sustained and expansion stresses. Sustained stress is one of the primary stress caused by weight such as pipe weight, insulation weight, fluid weight, etc. and pressure such as Internal and External Pressure. ASME B31 codes provide equations for sustained stress calculation and also provides allowable values to compare it with calculated sustained stress. Expansion stress is a displacement driven secondary stress generated in piping system due to temperature change or thermal differential between the installed and operating temperature. All B31 codes, ASME B31.1, ASME B31.3 etc. provide equation for calculating this expansion stress and then compare the calculated stress with allowable values. Read more...
Drums are cylindrical pressure vessels that are adopted in the process units for multiple functions.
The piping designer should cut down piping interconnections between the drum and its adjacent equipment when situating the drum.

TYPES OF REDUCERS IN PIPING INDUSTRY
Depending on process requirement or availability of material, there is a necessity of reducing or expanding the size of pipelines. Reducers are available in two styles:-
REBOILER FOR DISTILLATION
Reboilers is an exemplary heat exchanger that contributes vapor to drive fractional distillation separation. Reboilers typically are shell-and-tube exchangers that heat up the fractionation column fluid exploiting the heat shift from steam. Specific services may use other specialized designs including stab-ins, plate-fins, spiral-plates and others. Read more…
