304L Low Carbon Stainless Steel Blind Flange RF Anti-Sensitization Blank Flange for Welded Process Pipeline

1. Ultra-low carbon grade F304L, avoid intergranular corrosion after welding construction

2. PN16 pressure rating, thicker solid plate than PN10 model, higher safety margin

3. One-piece forging structure, uniform internal metallographic structure

4. Precision machined RF sealing surface, prevent medium penetration under fluctuating pressure

5. Stable performance for repeated welding, suitable for pipeline periodic modification & overhaul

6. Meet domestic GB standard, compatible with HG/T20592 series pipe fittings

   Available Materials: F304L, F316L, F321

   Application Scenarios: Environmental protection sewage medium-pressure pipeline end sealing, food factory process pipeline blanking, pharmaceutical auxiliary pipeline isolation, continuous chemical workshop pipeline maintenance blind, industrial circulating water pipeline reserved interface

   FAQ

1:How long is the custom lead time for stainless steel flanges in Wenzhou?

 — 8 to 10 working days

2:What is the fastest delivery time?

— 3 working days

3:Do you support non-standard custom flanges?

— Yes, we do.

4:Can you process special sizes?

— Yes. Max processing size: 4000 mm, Min processing size: 30 mm.

5:Do you have stainless steel flanges of standard sizes in stock?

— Yes.

6:Can we customize flanges based on customer drawings or samples?

— Yes.

7:Will material test certificates and inspection reports be provided for the purchased flanges?

— Yes, they will.

8:Is there a quality warranty for the flange products?

— Yes.

9:How to handle quality defects if they occur?

— Product return and exchange available.

10: When must we select 304L blind flange instead of 304?

— If on-site construction needs welding on adjacent flange area and pipeline will operate continuously after welding, choose 304L to eliminate weld corrosion hidden danger.
