Sanitary Clamp Ferrules | Welding Ferrules (Contract Manufacturing & Bulk Supply)
Engineering & Supply Chain Context: For process engineers and procurement managers sourcing critical hygienic components, consistency is currency. Sunhy provides factory-direct Sanitary Tri-Clamp Ferrules engineered for automated orbital welding. Unlike generic trading stock, we control the entire manufacturing process—from raw material selection (controlled Sulfur 316L) to final CNC machining. We offer stable lead times and fully traceable Mill Test Reports (EN 10204 3.1) with every shipment, ensuring your production line or inventory remains audit-ready for FDA/GMP compliance.
- Supply Model: Factory Direct / OEM Available.
- Traceability: Heat Numbers Laser Etched + MTRs.
- Capacity: Scalable Batch Production (1k - 50k units).
- Material: Restricted Sulfur (0.005-0.017%) for Welding Integrity.
- Surface: Ra ≤ 0.8µm Guaranteed (Internal).
- Compliance: Meets ASME BPE / DIN 32676 Standards.

1. Batch-to-Batch Consistency for OEMs For Original Equipment Manufacturers (OEMs) building skids or tanks, dimensional variation kills profitability. Our CNC centers use automated loading to ensure every ferrule maintains tolerances tighter than ASTM standards. We guarantee consistent face flatness and wall thickness across volume production runs, reducing rejection rates on your assembly floor.
2. Raw Material Integrity (The 316L Difference) We don’t just buy “stainless steel”; we source specific heats. Our 316L material is chemically validated to strictly limit Sulfur content (0.005%–0.017%) per ASME BPE Table DT-3. This prevents “arc wander” during orbital welding—a critical requirement for high-purity system integrators and pharmaceutical contractors.
3. Supply Chain Reliability We understand that a missing fitting can delay a million-dollar project. We maintain dedicated safety stock for standard ASME BPE and DIN sizes (1/2″ to 4″) to ensure rapid turnaround times. Our logistics team is experienced in export packaging to prevent face damage during sea/air freight.

1. Orbital Welding Parameters
Gas: 99.99% Argon purge required.
Gap Control: Ensure 0.00″ gap for autogenous welds.
Tip for Installers: Our machined square faces eliminate the need for field-facing in 95% of applications, saving labor hours.
2. Torque Specs for Assembly
Standard 13MHHM Clamps: 25 in-lbs (Wait 24hrs and re-torque due to gasket relaxation).
Preventing Leaks: 80% of leaks are due to misaligned ferrules, not gasket failure.

FAQ
Do you provide Mill Test Reports (MTRs) with the shipment?
Yes. As a professional manufacturer, we provide full EN 10204 3.1 material certificates with every order. The heat number is laser-marked on each ferrule for full traceability back to the steel ingot.
Can you manufacture ferrules to custom lengths or non-standard dimensions?
Yes. We offer custom CNC machining services. If you need a specific tangent length for a unique welding head or a non-standard bore size, send us your drawing or RFQ (Request for Quote)
What is your standard Lead Time for bulk orders?
For standard ASME BPE/DIN sizes (up to 4″), we typically ship within 3-5 days. For large OEM orders (>5,000 pcs) or custom productions, the standard production cycle is 20-25 days.
Do you offer private labeling or laser marking for distributors?
Yes. We can laser etch your brand logo, part number, and heat code onto the ferrules, helping you build brand loyalty with your local customers.
What are your payment terms for international distributors?
We support T/T and other standard international trade terms. Please contact our sales team to discuss credit terms for long-term partnership agreements.
