Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

What are the main advantages of stainless steel threaded pipe flange over welded versions?

Threaded flanges allow for faster installation and easier disassembly for maintenance without the need for cutting or re-welding, significantly reducing operational downtime.

How do you ensure the leak-proof quality of the threads?

We utilize high-precision CNC threading machines and verify every batch using certified go/no-go gauges to ensure a perfect tight fit across the entire thread length.

Can you provide custom dimensions for structural metal projects?

Yes, we offer full OEM/ODM services. Our engineering team can create custom thickness and diameter specifications based on your specific load-bearing requirements.

Which stainless steel grade is best for saltwater environments?

We highly recommend Super Duplex 2507 or SS316L for saltwater applications due to their high Pitting Resistance Equivalent Number (PREN).

What certifications accompany your products?

Every shipment includes a Material Test Report (MTR), a certificate of compliance to ISO 9001, and pressure test validation reports upon request.

What is the typical lead time for custom threaded flanges?

For custom structural specifications, samples are typically ready within 7 days, with bulk production following in 2-4 weeks depending on volume.
