Terms of Use

1. Acceptance of Terms

By accessing or using pvfcalculator.com ("the Site"), you agree to be bound by these Terms of Use. If you do not agree, please do not use the Site.

2. Purpose and Use of Calculators

The calculators provided on this Site are intended as engineering estimation tools based on published ASME standards (B16.5, B16.9, B36.10M). Results are theoretical weights and dimensions computed from standard dimensional data.

Calculator results are provided for:

• Preliminary engineering estimates and budgeting
• Freight and logistics planning
• Sanity-checking supplier invoices and quotations
• Educational and reference purposes

Results must not be used as a substitute for certified manufacturer data, certified material test reports (MTRs), or professional engineering sign-off for safety-critical applications.

3. Accuracy Disclaimer

While we strive for accuracy, calculated results are theoretical estimates subject to manufacturing tolerances, mill variation, and the specific edition of the ASME standard in use. Typical accuracy is ±3–5% of actual manufactured weights. We do not warrant that results are error-free or suitable for any specific engineering application.

4. Intellectual Property

The Site's design, content (excluding ASME standard data which is subject to ASME copyright), code, and original text are the intellectual property of PVF Calculator. You may not reproduce, distribute, or create derivative works without written permission, except for fair use quotation with attribution.

5. Prohibited Uses

• Automated scraping or bulk extraction of calculation results
• Using calculator output in safety-critical structural or pressure system design without independent professional engineering review
• Misrepresenting PVF Calculator as an endorsement or certification of any product or manufacturer
• Any use that violates applicable laws or regulations

6. Third-Party Links and Manufacturers

The Site may link to third-party manufacturer websites or refer users to manufacturers in response to quote requests. We do not endorse, verify, or warranty any third-party manufacturer's products, quality, or representations. Users must independently verify manufacturer qualifications and certifications.

7. Limitation of Liability

To the maximum extent permitted by applicable law, PVF Calculator shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Site or reliance on calculator results, including but not limited to freight cost disputes, procurement errors, or engineering decisions.

8. Changes to Terms

We may update these Terms at any time. Continued use of the Site following a change constitutes acceptance of the revised Terms.

9. Governing Law

These Terms are governed by applicable law. Disputes shall be resolved through good-faith negotiation before any formal proceedings.
