Spreadsheet Calculators
These calculator tools streamline calculations that are time-consuming to perform by hand, but not so complicated as to require the use of a specialized software. By embedding the relevant formulas, these calculators allow you to enter input data and quickly get the answer you seek. References to the source content are provided in the spreadsheets for all calculations.
Please read this End User Agreement carefully before using the Ingeniare spreadsheet calculators. By using the spreadsheet calculators, you are agreeing to be bound by the terms of this agreement.
(These spreadsheets are in a reserved area so if you are interested in reviewing them you can send us an email to info@ingeniare.net, and I will gladly send you a temporary access data. I will be very pleased to receive your suggestions and/or recommendations, also if you are interested to establish any professional relationship you can find my contact information on this webpage).

Spreadsheet calculator that follows the paragraph 304.1.2 "Straight Pipe Under Internal Pressure for t<D/6", the internal pressure design thickness for straight pipe shall be not less than that calculated in accordance with eq. (3a).


Spreadsheet calculator that follows the paragraph 403.2 "Criteria for Pipe Wall Thickness and Allowances". The nominal wall thickness of straight sections of steel pipe shall b equal to or greater than tn determined in accordance with the following equation: tn ≥ t+A


Spreadsheet calculator that follows paragraph 841.1.1 "Steel Pipe Design Formula for the design pressure for steel gas piping systems or the nominal wall thickness".


Spreadsheet calculator that follows paragraph 304.1.3 "Straight Pipe Under External Pressure" to determine wall thickness and stiffening requirements for straight pipe under external pressure.


Spreadsheet calculator that follows "Offshore Liquid Pipeline Systems" (Chapter IX), paragraph A403.2 "Criteria for Pipe Wall Thickness and Allowance".


Spreadsheet calculator that follows "Offshore Gas Transmission" (Chapter VIII), paragraph A842.2.1 "Strengh Criteria During Operations".


Wall Thickness Calculation of Offshore Pipes by API RP 1111
Spreadsheet calculator that follows the API RP 1111 "Design, Construction, Operation, and Maintenance of Offshore Hydrocarbon Pipelines (Limit State Design)".


Spreadsheet calculator that follows paragraph 304.3.3 "Reinforcement of Welded Branch Connections". Added reinforcement is required to meet the criteria in paras. 304.3.3(b) and (c) when it is not inherent in the components of the branch connection.


Spreadsheet calculator that follows Spacing Between Supports by Design of Piping Systems, The M. W. Kellogg Company. The spacing is based on a fixed beam support with a bending stress not exceeding 2,300 psi (15.86 MPa) and insulated pipe filled with water, and the pitch of the line is such that a sag of 0.1 in. (2.5 mm) between supports is permissible. (As per table 121.5 on ASME B31.1).


Pressure-Temperature Ratings for Group Materials by ASME B16.5
Spreadsheet that calculate the working pressure and pressure-temperature rating for flanges with rating class designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 1⁄2  (DN 15) through NPS 24 (DN 600) and flanges with rating class designation 2500 in sizes NPS 1⁄2 (DN 15) through NPS 12 (DN 300).


Pressure-Temperature Ratings for Group Materials by ASME B16.47
Spreadsheet that calculate the working pressure and pressure-temperature rating for flanges with rating class designations 75, 150, 300, 400, 600 and 900 in sizes NPS 26  (DN 650) through NPS 60 (DN 1500).
