Who owns Heatline
Heatline is operated by Axion Development, LLC, a Texas limited liability company. Heatline is the product name. Axion Development, LLC is the legal name on Stripe, the mill request, and the invoice. Contact is hello@axiondevelopment.co. You get a limited license to pull certs for your own jobs. You do not get the right to copy the app, resell access, or scrape the index.
The mill stamp is the legal cert
Heatline shows indexed mill-test records for heat lookup and trace. They are not a substitute for the producing mill’s original EN 10204 / ASTM mill stamp. If a job, owner, or inspector requires the original 3.1, chase the mill. Do not present a Heatline print as the mill’s certificate.
Your job, your check
You confirm heat number, size, grade, and coating against the pipe in hand. Heatline is not the mill, the fabricator, or the inspector of record.
Fees
Inspector, Yard, and Trace are subscriptions billed by Axion Development, LLC through Stripe. Mill chase is $99 per heat when the original 3.1 is not in the index. Indexed pulls are not billed per click. Paid plans start when Stripe checkout completes.
What we store
Recent heats, selected plan, and chase requests can sit on this device. Do not put customer POs, SSNs, or controlled drawings in the chase note if you would not put them on a shop whiteboard.
Texas law
