(Draft) Excel table formula to calculate NPSHR (Net Positive Suction Head Required)

-
Here is the Excel table formula to calculate NPSHR (Net Positive Suction Head Required) in metric units: =(((Pb - Pv) / (rho * g)) + h) This formula is designed to calculate NPSHR in metric units, and the result will be in meters (m). In the formula, the variables have the following units: Pb: Pressure of the liquid at the pump suction measured by a gauge (in units of Pa or kPa). Pv: Vapor pressure of the liquid at the pump suction (in units of Pa or kPa). rho: Density of the liquid at the pump suction (in units of kg/m^3). g: Acceleration due to gravity (approximately 9.81 m/s^2). h: Elevation difference between the pump suction gauge and the liquid surface (in units of meters, m). To calculate NPSHR using the above formula in an Excel table, follow these steps: 1) Enter the formula into the desired cell in the Excel table. 2) Input the values for each variable, either through cell references or directly as numerical values. Make sure to use metric units for the variables Pb, Pv, rho,

ISO 15156 (=NACE MR0175) and NACE MR0103

-
1. A part of job specification All materials for components exposed to wet hydrogen sulphide in concentrations exceeding 100 mg/kg (100 ppm) or exceeding the limits prescribed by ISO 15156 or NACE MR0103 (as applicable) shall conform to the reduced hardness requirements of ISO 15156 or NACE MR0103 as follows: a. ISO 15156 is applicable to oil and gas production facilities and natural gas sweetening plants. (NACE MR0175 is equivalent to ISO 15156). b. NACE MR0103 is applicable to other applications (e.g., oil refineries, LNG plants and chemical plants). c. The previous requirements (a) and (b) equally apply to all external bolting on the casing and seal glands even if ISO 15156 or NACE MR0103 (as applicable) restricts the requirement to enclosed bolting. 2. Interpretation by NACE MR0103 and ISO 15156 (=NACE MR0175) The hardness limitations specified in NACE MR0103 and ISO 15156 vary depending on the specific materials and conditions. Here are the general hardness limitations provided by

(Rev.0) Visual inspection acceptance criteria for welded piping spools

-
In ASME B31.3, the acceptance criteria for visual inspection of welded piping spools can be found in several sections, including: Section 328: Examination and Testing During Construction, which provides requirements for the visual examination of welds and the acceptance criteria for surface discontinuities. Section 341: Examination and Testing After Welding, which includes guidelines for visual inspection of completed welds and criteria for acceptance or rejection. Section 341.5: Acceptance Criteria for Welds, which specifies the acceptance criteria for various types of weld discontinuities based on their size, shape, and location. Additionally, other standards such as AWS D1.1 (Structural Welding Code - Steel) and API 1104 (Welding of Pipelines and Related Facilities) may also be referenced for visual inspection acceptance criteria for specific applications.
