What flange standards are supported?

We support ANSI B16.5, DIN 2501, JIS B2220, and BS 4504 standards.

How does the price vary with material upgrades?

Prices are based on SS304 and EPDM. Upgrading to SS316/316L or higher pressure ratings increases the price due to raw material costs.

AI-Powered supplier vetting

SummaryThe supplier is a small limited company with three employees, offering Spring Steel Cold Coin and a broad range of hardware, building-material, ceramic, automotive, motorcycle, timber, packaging, and related products. It has flexible customization capability but no ODM service, popular-brand OEM capability, SDK, overseas warehouse, overseas showroom, overseas agent or branch, or in-stock service capacity. The supplier reports one year of export experience and lead times of within 15 working days to one month. Its service controls include 10 qualified suppliers and relevant records, but no written assessment procedure or corrective/preventive-action procedures. Quality-assurance, traceability, fire-drill, and environmental-assessment statuses are unknown, while quality-control test equipment is listed as zero. A TUV Rheinland audit is recorded, but the audit result is listed as 0; the stated report validity ended on 2025-10-14. No evidence of customer cases or offline trade-show participation is provided.

After-Sales capabilityThe supplier has 10 qualified service-capability suppliers and accepts FOB, CIF, CFR, LC, and T/T terms, but it has no overseas warehouse, showroom, overseas agent or branch, or in-stock service capacity. Complaint handling is recorded as “Others,” without a defined method, while quality-assurance and traceability statuses are unknown.

R&D capabilityThe supplier launched no new products during the past year and does not provide ODM services, popular-brand OEM services, or an SDK. One R&D engineer is listed, whose responsibility is to handle product photos, so the available evidence does not demonstrate substantive product-development capability.

Production capacityThe supplier has three employees, no in-stock capability, and no overseas service infrastructure. Reported lead times are within 15 working days to one month in both off-season and peak season, but quality-control test equipment is listed as zero and formal service corrective/preventive-action procedures are absent.

Customization capabilityThe supplier explicitly states that it provides flexible customization. This is direct evidence of customization availability, although no details are provided regarding customization scope, tooling, technical support, or delivery impact.

Product Q&A

Q:How do I choose between SS304 and SS316 flanges?

SS304 is standard for Food, Water, and General Chemical industries. SS316 contains Molybdenum for better corrosion resistance, mandatory for Marine (Sea Water) and strong Acid/Alkali applications.

Q:Is the rubber joint safe for food processing?

Yes. We provide Food Grade White EPDM rubber bodies that are odorless, non-toxic, and meet sanitary standards for milk, beer, and drinking water.

Q:Can you provide the Material Test Certificate (MTC)?

Absolutely. We provide the MTC for every batch of Stainless Steel flanges, proving the chemical composition (Ni, Cr, Mo content) meets international standards.

Q:Is the flange surface rough or smooth?

Unlike cast iron flanges, our Stainless Steel flanges are CNC Machined with a smooth, shiny, and precise sealing surface for a perfect seal and premium look.

Q:Can you laser mark my Logo on the stainless steel flange?

Yes! We offer Laser Marking service to engrave your Logo, Size, and Material grade directly onto the metal flange for a professional finish.
