Burst Pressure

Calculate the burst pressure or a thickness that will result in a burst given a pressure for a cylinder and a sphere based on the analysis procedure developed by Svensson [1]. Svensson’s method is applicable to the full range of radius to wall thickness ratios, i.e. both thick and thin cylindrical and spherical shells may be analyzed. Svensson’s method makes use of a stress-strain model that includes the effects of strain hardening. The material model used is the Prager stress-strain curve model [2]. A materials database is provided. Two Options are provided.

 

  • Option 1 – Determine the burst pressure given the geometry, materials of construction and temperature
  • Option 2 – Determine the thickness that will result in a burst for a specified pressure given the geometry, materials of construction and temperature

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
  • In-Service Option – Determine the retirement thickness given the geometry, materials of construction, design pressure, design temperature and applied loadings

A materials database for these code is provided. Two Options are provided.
 

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

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.

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 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.
 
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.

Charpy Data Analysis

Fit Charpy impact test data to the hyperbolic tangent function, a transition function that is commonly used to represent a Charpy transition curve: CVN=A+B∙tanh[(T-D)/C], see below.
 

 
The variation of Charpy V-notch Impact Energy (CVN) with temperature can be modeled using a transition function such as the typical hyperbolic tangent function. The transition curve has a lower shelf, a transition zone, and an upper shelf. The Fracture Appearance Transition Temperature (FATT) is defined as the temperature corresponding to 50% shear and may be approximated as point D in the image above. A fracture toughness may be determined using the 20 ft-lb (28 Joule) energy that can be calculated from the hyperbolic tangent function after fitting by using Wallin’s Fracture Toughness Master Curve (see WRC 562).

The MAT is determined in accordance with WRC 562 and includes the effects of residual stress. In addition, the WRC 562-MAT curves may be determined based on a t/4 or t/8 reference flaw.
