FAQ
Frequently Asked Questions
Are these calculations accurate enough for procurement?
Yes. All calculators use official ASME B16.5 / B16.9 dimensional data and material densities. Results match manufacturer weight tables within ±2%. For final procurement, always confirm with factory MTC.
How do I get a factory quote?
Use the Request a Quote form or email quotes@pvfcalculator.com with your specs (standard, material, size, quantity). We respond within 24 hours with factory-direct pricing.
What standards do your calculators support?
ASME B16.5 (flanges), ASME B16.9 (butt-weld fittings), ASME B36.10M (pipe weights), and MSS SP-75 (high-strength fittings). We also support EN 1092-1 and JIS standards on request.
Can you manufacture non-standard sizes?
Yes. Our partner factories in Cangzhou specialize in custom and OEM fabrication — non-standard wall thicknesses, special alloys, and prototype quantities. Send drawings for evaluation.
Do you ship worldwide?
Yes. FOB Tianjin / CIF / DDP terms available. Sea freight to major ports, air freight for urgent orders. Full export documentation including MTC, packing list, and certificate of origin.
Can I source valves through this site?
Yes. Use our Valve Cv and Valve Weight calculators to verify specifications, browse the Wenzhou valve manufacturers page to find qualified factories, then submit your inquiry via Request a Quote.
Do you cover pressure vessel design?
We provide ASME VIII UG-27 / UG-32 wall thickness calculators for shells and heads under internal pressure. These tools assist preliminary sizing only and do not replace the review of an Authorized Inspector or a qualified pressure vessel engineer.
