TracPipe UK Sizing & Reference vs Gas Pipe Sizing Plumb

This App allows the user to size the TracPipe® Flexible Gas Piping product, using an appropriate sizing method. The App displays the appropriate size of TracPipe® 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 UK Size and Capacity Calculator must be sized in accordance with an appropriate sizing method, such as the method and example detailed in Appendix A (Informative) of BS 6891: 2015 Specification for the installation and maintenance of low pressure gas installation pipework of up to 35 mm (R1¼) on premises. The piping system designer must assure that the installation pipework is of adequate size to ensure that all appliances connected operate at their required heat input in accordance with the appliance manufacturers’ instructions. The user can research the latest TracPipe® Design and Installation Specification by simply selecting the topic he wishes to view in the document index. He will be automatically forwarded to the selected page. To return to the index select the page number at the bottom.

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.
