Plate Flanges

Handling low to medium pressure pipelines often brings sourcing delays due to inconsistent bolt alignment or flange flatness. Our Plate Flanges (PF Flange) supports direct welding on pipe ends, helping ensure fast gasket fit-up and stable sealing. 

Standard Specification

EN 1092-1 (Type 01), DIN 2576, JIS B2220, ISO 7005 (PN series)

Pressure Rating

PN6 to PN40

Material

Carbon Steel (S235JR, P265GH), Stainless Steel (AISI 304/316), Aluminum (EN 485-2)

Nominal Size

DN15 to DN4000 (½” to 160″)

Flange Type

Plate/Flat (PF)

Product Description

Limited dimensional accuracy in budget flanges can increase site rework and delay testing. We offer standard-compliant Plate Flanges across EN 1092-1, DIN 2576, and JIS B2220 formats to meet global specifications with repeatable quality. 

Facing Type

lat Face (FF)

Dimensions

Thickness: 5-100mm (customizable)

Bolt Circle Diameter

EN/DIN standard ±2mm tolerance

Number & Size of Bolt Holes

4 to 36 holes (M10 to M36 bolts)

Surface Finish

Shot blasted (SA 2.5) or machined (6.3μm Ra)

Corrosion Resistance

Coating-dependent (epoxy/zinc) or stainless steel

Temperature Rating

20°C to +300°C

Material Certification

EN 10204 2.2/3.1, PED Category I

Gasket Compatibility

Full-face gaskets (rubber/cork)

Coating/Plating

HDG, FBE, Aluminum spray

Manufacturing Method

CNC-cut from plate + machining

Technical Advantages

Flat-faced flanges must maintain even surface contact for full-face gasket sealing. Our Plate Flanges come CNC-cut from plates with up to ±2mm bolt circle tolerance for easy alignment. 

Poor coating or weak bolting zones can shorten flange lifespan. We offer shot-blasted or machined faces, HDG or FBE coating, and sizes from DN15 to DN4000 to match your layout.

Industry Applications

Water Distribution Pipelines

Works in PN10 to PN25 pressure setups, easing fitment with rubber full-face gaskets in municipal lines. 

Thermal Power Plants

Used in low-pressure ducting and heat exchanger headers, where flat face sealing supports corrosion-resistant gaskets. 

HVAC Duct Systems

Supports flange-end spiral ducts with bolt patterns for fast joint sealing in chilled or heated air lines.

Agricultural Irrigation Units

Handles flange terminations in large-diameter irrigation headers and control valve networks. 

Industrial Air Handling Systems

Serves low-pressure exhaust and blower piping, where FF flanges reduce vibration stress. 

Wastewater Treatment Plants

Supports PN16-rated process lines handling non-aggressive fluids across aerobic treatment setups.

Standard Fitment Across Pressure Lines

High-volume line installations need flanges with consistent tolerances, easy gasket compatibility, and minimal machining defects. Our PF Flanges maintain 6.3μm Ra surface finish, ensuring gasket grip and reliable sealing across varied temperatures. 

Aluminum, stainless, or carbon steel options help you match end-use durability, pressure range, and corrosion resistance without overspending. Each unit is backed by EN 10204 3.1 certification and PED compliance for regulatory confidence.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

Can you match bolt hole patterns across different flange standards like DIN and JIS?

Yes, we manufacture using exact standards and verify bolt circle diameters during inspection. We follow ±2mm tolerance on BCD and hole spacing to prevent mismatch during assembly. Mixed-standard projects can be supported with full documentation. 

Do you provide material traceability for stainless and carbon steel Plate flanges?

Yes, each batch carries heat numbers with material certificates per EN 10204 3.1 or 2.2. This ensures traceability back to the base plate used for CNC cutting. We also record PED compliance where needed.

How do you maintain face flatness across large-diameter Plate flanges?

We CNC-machine faces after plate cutting to control flatness and surface finish. Thickness is checked at multiple points to stay within drawing specs. This ensures the full-face gasket seals properly without excess compression loss.

What packaging method do you use to avoid coating damage during shipping?

We pack flanges with plastic wraps and edge guards before placing them in wooden crates. Coated units get additional film or VCI layers depending on sea or land transit. Every crate includes quantity and spec labeling for faster inward inspection. 

Can I request PN16 and PN10 flanges in the same material grade and coating?

Yes, we supply multiple pressure ratings under one MTC batch using the same raw plate. Just mention the coating type and pressure class during inquiry. This helps reduce sourcing complexity across similar pipeline sections.
