Engineering Services, Inc. has extensive experience in design, analysis
and re-rating of Pressure vessels used in refineries, chemical plants,
power plants, nuclear plants and other processing facilities. Some of
the capabilities of PEESI in the area of pressure vessels are listed as follows:
analysis of Pressure Vessels (Tall Columns,
Vessels, Horizontal Pressure Vessels,
Spherical Vessels, Reactors
etc.) based on ASME
Pressure Vessel Code, Section VIII, Div. - 1, Div. - 2
and Div. - 3.
Analysis of Power
Boilers per ASME Boiler & Pressure Vessel Code, Section-1
Calculations for repair
and alteration of existing Pressure Vessels per API-510 and
National Board Inspection Code.
minimum retirement thickness values for existing pressure vessels /
pressure vessel components to
maximize the remaining safe and useful life.
of pressure vessels for a new set of design parameters.
Calculations to check the
suitability of vessels for in-situ PWHT.
for pressure vessels to assure the structural integrity of equipment
for the intended design parameters and to offer life extension
Fatigue analysis to calculate the fatigue life of pressure vessels subjected to pressure
cycles, temperature cycles and startup / shutdown cycles.
Analysis to identify the root cause of failure for the failed
pressure vessels or pressure vessel components.
Analysis for pressure vessels and pressure vessel components.
Pressure vessel certification, calculations and rating /
re-rating for pressure vessels that do not contain sufficient design
information in their files.
Design of Structural
systems and supports for continued operation of leaked vessels or
vessels that violate the minimum required thicknesses based on
Evaluation of cracks
and Flaws in pressure vessels by applying Fracture Mechanics
Evaluation of Minimum
Safe Operating Temperature (MSOT) for existing vessels which do not
meet the current MDMT requirement of the ASME Code.
Evaluation of Pressure
Vessels after accidental over-pressurization.
for Pressure Vessels involving special situations of Structural and
Analysis to assure
Mechanical Integrity of Pressure Vessels for following type of
flaws: Generalized corrosion, Localized corrosion / Thinning, Blisters,
Laminations, Bulges, Gouges, Dents, Cracks etc.
