This page is a record template, not a published gas recipe. The five rows identify material families only; no verified grade-specific wall, gas, flow, or pressure values are available here. Complete a row from the current tube-machine/head OEM chart or an approved test record. Until that source matches the job, leave the process unverified and do not carry it into a quote.
Content reviewed 2026-11-02. Verify the applicability of each source before using a value in a quote.
Input to record
Exact grade and profile; nominal or measured wall in mm; installed machine, head and fixture; source-specified gas; flow value, original unit and meter basis; pressure value, source unit, gauge/absolute basis and measurement point; source revision and test result.
Output to carry forward
A scoped, source-linked gas record. It is ready for cycle-time or cost review only when the material, wall, head/fixture, and measurement basis match the approved OEM record or shop test.
Sources and scope
Content reviewed 2026-11-02. A documentation reference supports the stated method or data only; it does not approve settings on another machine.
- BLM GROUP LT7 technical information
The manufacturer lists LT7 model and material categories, but does not publish gas, wall, flow, or pressure recipes. Do not interpret the hardware page as a process recommendation.
- Alicat: Mass Flow vs. Volumetric Flow
Use the meter specification to retain actual or reference-state flow units and conditions. This explains measurement basis only; it is not a tube-cutting setting source.
Record units and conditions
Enter wall thickness in mm and identify whether it is the drawing value or a measured stock value. Preserve the flow meter's original unit (for example, L/min, standard L/min, or m³/h) and its actual/reference conditions; actual and standardized volumetric readings are not interchangeable. Record pressure in the source's unit, whether it is gauge or absolute, and where it was measured. Pressure alone does not establish flow.
Example: for a stainless tube job, choose the stainless row, then match its exact grade, profile, wall, installed head/fixture, and gas source. Copy flow and pressure only from that matching current OEM chart or approved test. If no matching source exists, keep the row unverified. To price consumption, carry a measured gas-on flow and duration with the same volume basis to the gas consumption calculator; do not infer flow from nozzle size or pressure.
A gas record is not a gas recommendation
The row is useful when it traces a tube job's measured or OEM-specified gas input to a defined machine, material, wall and fixture scope.
Consumption is estimated from measured flow multiplied by non-overlapping gas-on time, with matching units and volume basis. The worksheet does not select the gas or convert pressure into flow.
Re-check the source when grade, wall, head, fixture, supply, meter basis or controller setup changes. A flat-sheet row does not qualify tube processing.
Reference workflow
- Match the job, material, machine head, and quality requirement to a row.
- Confirm the source, review date, and confidence before copying the value into a quote worksheet.
- Use a measured result or current OEM record when the row is marked as required or unverified.
