Why Choose Our Precision Machined Stainless Steel Rings?
Our rings are not just components; they are engineered solutions that enhance the performance and longevity of your valve systems. Here are the advantages you gain:
- Enhanced Seal Integrity: The precision-machined flat surface ensures uniform contact with valve gaskets, minimizing leakage and reducing maintenance frequency.

- Consistent Quality from ISO9001 Factory: Our ISO9001-certified processes include in-process inspection, dimensional checks, and material certifications (mill test reports available upon request).
- Flexible Order Quantities: We handle both small trial orders (as low as 50 pieces) and large production runs (up to 50,000 pieces per month) with the same attention to detail.
- Global Logistics: Shipped from Shenzhen, Dongguan, or Guangzhou ports, with efficient customs clearance and reliable freight partners serving all major markets.

Frequently Asked Questions (FAQ)
Q1: What is the exact material of your ring? Is it genuine 304 stainless steel?
A: Yes, we use genuine 304 stainless steel (also known as 1.4301) sourced from certified mills. Material test certificates are available upon request to verify composition.
Q2: Does the ring comply with ASME B16.5 flanges? What pressure classes are available?
A: Our rings are designed per ASME B16.5, covering classes 150, 300, 600, and custom pressure ratings. We can also adjust dimensions to match specific flange standards (e.g., DIN, JIS) if needed.
Q3: Can you produce rings with a different surface finish, such as a mirror polish or a rougher texture?
A: Absolutely. The standard machined finish is Ra ≤ 3.2 μm, but we can achieve Ra ≤ 1.6 μm, Ra ≤ 0.8 μm, or other finishes per your specification. Just let us know your requirements.
Q4: What is the minimum order quantity (MOQ) for custom-sized rings?
A: For custom sizes, our MOQ is typically 100 pieces, but we can accommodate smaller quantities (e.g., 50 pieces) for trial orders. Please contact us with your dimensions and quantity.
Q5: How long does it take to produce and deliver an order?
A: Lead time depends on complexity. For standard sizes, we can ship within 7-10 days after order confirmation. For custom rings, the typical lead time is 15-25 days. Shipping time varies by destination (e.g., 3-5 days to US via air, 20-30 days by sea).
Q6: Do you provide samples for quality evaluation? How much does it cost?
A: Yes, we offer samples. Sample cost is based on the ring size and quantity, and we usually deduct the sample fee from the bulk order. Please send an inquiry for a sample quote.
Q7: What kind of packaging do you use for export?
A: We carefully pack each ring in plastic bags, then cushion them with foam or bubble wrap inside cartons or plywood cases. Custom packaging (e.g., individual blister packs, wooden spools) is available for an additional cost.
Q8: Are your rings traceable? Do you provide any quality documentation?
A: Yes, each production batch has a unique lot number. We can provide material certificates, dimensional reports, and ISO9001 compliance documentation. Our quality records are retained for at least 5 years.
