TracPipe System Guide vs Gas Pipe Sizing Plumb

This App allows the user to size the TracPipe® System Flexible Gas Piping products, to either the Longest Run or Branch length method of gas pipe sizing. Whether the installation is in TracPipe, TracPipe AP, or TracPipe PS-II CSST (Corrugated Stainless Steel Tubing). The App displays the appropriate size of piping for a given capacity depending on the type of gas, supply pressure and allowable pressure drop selected by the user. By selecting the design parameters using easy drop-down menus the user then chooses the length of pipe and tubing size on the easy-to-read calculator wheel to find the capacity capable of being delivered by any of the seven sizes offered by TracPipe. Gas piping systems sized with the TracPipe Size and Capacity Calculator must be sized in accordance with the steps for the Longest Length Method or the Branch Length Method as outlined in Chapter 4 of the International Fuel Gas Code or Chapter 6 of the National Fuel Gas Code. The piping system designer must assure that the pressure drop is such that the supply pressure at the appliance is greater than or equal to the minimum pressure required by the appliance. This App provides access to multiple features including our TracPipe System Flexible Gas Piping Design Guide & Installation Instructions (D&I Guide), Price Sheet, Fitting Assembly Videos and Instructions, Contact Us Information, and our Training Portal.

Gas Pipe Sizing Calculator helps you size natural gas and propane piping systems per the printed NFPA 54 (National Fuel Gas Code) / IFGC sizing tables. Instantly determine correct pipe diameter for black iron, CSST (corrugated stainless steel tubing), and semirigid copper piping based on BTU demand, inlet pressure, and pipe run length. Works for low-pressure, 2-psi, and 5-psi natural gas systems and low-pressure and 2-psi propane systems. Perfect for plumbers, gas fitters, and HVAC technicians. Works 100% offline on the job site. FEATURES - Dual Gas Support: Natural gas and propane (LP) each use their own printed NFPA 54 / IFGC capacity tables - no approximation multipliers - 3 Pipe Materials: Black iron (Schedule 40), CSST (by EHD flow designation), and semirigid copper with material-specific printed tables - Inlet Pressure Classes: Low pressure (under 2 psi), 2 psi, and 5 psi for natural gas; low pressure (11" w.c.) and 2 psi for propane (the code has no printed 5-psi LP tables) - Pipe Diameters: Black iron 1/2" through 4"; copper and CSST 1/2" through 2" (CSST capacities per conservative EHD for each nominal) - 10 Length Brackets: Pipe runs from 10 feet to 200 feet, rounded up per code practice - BTU Input: Enter appliance or total system demand in BTU/h - Result Note: Shows the exact NFPA 54 / IFGC table used for every result HOW IT WORKS 1. Select gas type (natural gas or propane) 2. Enter inlet pressure (low pressure, 2 psi, or 5 psi) 3. Input total BTU demand from gas appliances 4. Enter pipe material (black iron, CSST, or copper Type L) 5. Enter longest pipe run distance 6. See recommended pipe diameter with NFPA 54 capacity verification PERFECT FOR - Plumbers installing natural gas and propane systems - Gas fitters and propane technicians - HVAC technicians sizing gas furnace piping - Plumbing contractors and estimators - Mechanical engineers designing gas systems - Plumbing inspectors verifying system compliance OPTIONAL PRO UPGRADE — $2.99 ONE-TIME IN-APP PURCHASE The following features require a separate one-time in-app purchase. They are not required to use the calculator: • Unlimited saved calculation history • PDF export of results • Dark theme • Ad-free experience STANDARDS & COMPLIANCE Capacities follow the printed NFPA 54 (National Fuel Gas Code) / IFGC Section 402.4 sizing tables: Schedule 40 steel (Tables 402.4(2)/(5)/(7) natural gas, 402.4(28)/(27) propane), semirigid copper (402.4(9)/(12)/(14) and 402.4(30)/(31)), and CSST by EHD (402.4(15)/(18)/(19) and 402.4(32)/(33)). Always confirm with your local code official and the tubing manufacturer table for CSST. PERFECT FOR - Plumbers and gas fitters - HVAC technicians and contractors - Propane technicians and installers - Plumbing contractors and estimators - Mechanical engineers - Code officials and inspectors OFFLINE & PRIVACY - Works 100% offline - no internet needed for calculations - No account required - instant access without signup - No data collection - all calculations stored locally - No tracking or cloud dependencies Part of PlumbTools Suite - professional plumbing and HVAC calculator tools. Size gas systems faster, eliminate sizing errors, and ensure full NFPA 54 code compliance with accurate gas pipe sizing calculations.
