Damage Web

With a technical basis in API RP 571 and WRC 489, Damage for the web is an invaluable reference guide for identifying and understanding the potential damage mechanisms that can cause costly fixed equipment failure. Similar to the desktop version, the heart of Damage for the web is the Solver. By selecting filter criteria (process unit, material, operating temperature, source and morphology), the Solver will quickly identify the possible damage mechanisms from the complete list defined in API 571, highlighting the most likely mechanisms for the selected criteria. The list of damage mechanisms is hyperlinked to the section of the 571 document pertaining to that mechanism. The document is presented in accordion format for mobile-friendly viewing and includes image links for appearance or morphology of damage.

A comprehensive Material look up reference tool for specifications, chemistry, hardness, fired heater limits, weld and pump materials is available. Process Flow Diagrams may be accessed from a pull down menu or from the Solver. Damage mechanisms shown on the PFDs are hyperlinked to the relevant 571 section. In addition to the calculators for sulfidation, H2S corrosion, and oxidation found in the desktop version, there are additional API 581-compatible susceptibility calculators for amine, sulfide stress, and caustic cracking.

Hydrogen Bake-Out

Determine the time required for a hydrogen bake-out operation at a user specified temperature to ensure that the remaining hydrogen concentration in the vessel wall is no greater than a user specified maximum value. Cylindrical and spherical vessels may be analyzed. The materials of construction may be specified as carbon steel or a low chrome alloy steel. The shell may include a Type 300 series stainless steel internal cladding or weld overlay, or a Type 410 cladding. A transient diffusion analysis is performed and the hydrogen concentration in the vessel wall is determined as a function of the shut-down time cycle.

When welding onto hydrogen-charged steel, hydrogen in the vessel wall increases the risk of cracking due to hydrogen embrittlement as the weld metal cools and higher levels of residual stress are induced in the weld region. To reduce this risk, atomic hydrogen present in the steel should be baked-out prior to welding. This is accomplished by heating the steel to a temperature for a sufficient period of time to allow the absorbed hydrogen to diffuse back out of the steel. Heating is required, because both the diffusivity and solubility of hydrogen in steel is a rapidly increasing function of temperature.


Material Explorer

Access to E2G’s extensive material database for materials typically used in the construction of pressure vessels, piping and tankage is provided. The database includes:

  • Material physical properties – Young’s Modulus’s, thermal expansion coefficient, thermal conductivity and thermal diffusivity as a function of temperature.
  • Strength parameters – yield and tensile strength as a function of temperature.
  • Allowable design stresses as a function of temperature, allowable stress may be determined based upon a specific year of the code shown below.
    • ASME Boiler and Pressure Vessel Code Sections I, Section VIII, Divisions 1 and 2
    • ASME B31 Piping Codes B31.1, B31.3, B31.4 and B31.8
    • API 620, API 650, API 653

The above properties are determined for a specified input temperature. Supplemental output including tables and graphs of material properties as a function of temperature is also provided.


Reactor Shutdown

Determine the hydrogen concentration in cylindrical or spherical vessel wall given the steady state operating conditions, i.e. pressure and temperature, and a specified shut-down rate, both pressure and temperature may be specified. The materials of construction may be specified as carbon steel or a low chrome alloy steel. The shell may include a Type 300 series stainless steel an internal cladding or weld overlay, or a Type 410 cladding. A transient diffusion analysis is performed and the hydrogen concertation in the vessel wall is determined as a function of the shut-down time cycle.

Pipe Span Pressure-Thickness

Calculations to determine the required thickness or MAWP (MAOP) of a pipe span are performed such that a user-specified maximum deflection and slope are not exceeded. Calculations are performed in accordance with the ASME B31.1, B31.3, B31.4 and B31.8 Piping Codes. A materials database for these codes is provided. Concentrated loads can be included and adjusted to model flange junctions, valves and the weight of a person. Distributed loads automatically included in the calculations are the weight of the pipe, insulation, and fluid contents. Longitudinal, circumferential and stress at the supports are computed in addition to pipe properties including metal cross-sectional area, section modulus, moment of inertia and weight. In the weight calculation, the additional weight due to insulation, refractory, and the fluid is accounted for. If refractory properties are input, a modified moment of inertia is computed to model the increase in stiffness due to the specified refractory thickness and its modulus of elasticity. Two options are provided:

  • Design Option – Determine the required thickness and recommended nominal thickness given the geometry, materials of construction, design pressure, design temperature and applied loadings
