As a US-based procurement or engineering manager, you’ve likely faced these frustrations:
You need a partner – not just a vendor. One that provides stainless steel flanged fittings with factory-direct pricing, ASTM-certified materials, and a supply chain that works for you.
With 15+ years of export experience and a dedicated engineering team, we manufacture and export flanged fittings that meet the strictest US and international standards. Here’s what sets us apart:
Casting, machining, assembly, and testing under one roof. No middlemen. Cost reduction of 25-35% compared to US distributor prices.
ISO 9001:2015 certified. Every flanged fitting is pressure-tested and traceable to the melt. CE, RoHS, and CRN (Saudi Arabia/Aramco) compliant.
Need a special bore diameter or custom face-to-face dimension? Our senior engineers (10+ years average experience) modify designs in 72 hours.
Standard lead time: 14 working days for flanged fittings. Express production in 7 days for emergency orders. Stock available for popular sizes (½” – 24”).
We ship to ports across the USA (Los Angeles, Houston, New York). DDP terms available – you get the fittings without customs headaches.
Speak directly to our senior engineer or operations manager. Response in under 2 hours during business hours. No IVR, just answers.
All fittings manufactured in accordance with ASTM A351 / A182, ASME B16.5, and MSS SP-25.

“Ordered 120 units of SS304 flanged fittings Class 150. The machining quality is excellent – threads are clean, faces flat within 0.002”. Shipping was 13 days door to door. Will definitely reorder.”
“We saved 32% compared to our previous US supplier. The CF8M fittings came with full PMI reports. Zero defects in 600 units. Thriveon has earned a spot on our preferred vendor list.”
“Very responsive team. Helped me with a custom bore for a special actuator. The only small issue was the packaging could be stronger for heavy fittings, but they improved it after my feedback. Solid partner.”
“Aramco approved supplier that actually delivers on time. We used their Class 600 flanged fittings on a gas separation project. Documentation was complete, and the quality passed 3rd party inspection easily.”
“The CE marked fittings arrived with the correct PED documentation. Our inspector was impressed by the traceability. Highly recommended for European projects.”
