Raised Gasket Area

Raised Face (RF)

Most common. A raised circular ring that concentrates pressure on a smaller area to compress the gasket. Height: 1/16" for Class 150/300; 1/4" for Class 400 and above.

100% Flat Mating Surface

Flat Face (FF)

No raised portion; entire flange face is in the same plane. Used when mating against cast iron or non-metallic flanges to avoid cracking on bolt tightening.

Deep Metallic Ring Groove

Ring Type Joint (RTJ)

Oval or octagonal groove machined into the face; a metal ring gasket seats in the groove. Used in high-pressure, high-temperature critical service (refineries, oil fields).

Interlocking Alignment

Tongue & Groove (T&G)

One flange has a raised ring (tongue); the other a matching groove. Provides excellent alignment and a confined gasket. Used in pumps and valve bonnets.

Recessed Female Mating

Male & Female (M&F)

Similar to T&G but the female face is flat and the male face raised. Used in heat exchangers, pressure vessels, and high-integrity process joints.

Heavy-Duty Contact

Large Male & Female

Same operating principle as the standard Male & Female flange, scaled up with larger step contact surfaces for specialized heavy industrial equipment.

Hydrostatic / Hydro Pressure Test

Each flange pressure tested at 1.5x working pressure per ASME code requirements.

Ultrasonic Testing (UT)

Non-destructive testing to detect internal sub-surface cracks, inclusions and forging defects.

Radiographic Testing (RT / X-Ray)

100% radiography available; mandatory for critical Class 900+ high pressure services.

Positive Material Identification (PMI)

Spectrometer validation to verify alloy chemistry precisely matches the Mill Test Certificate.

Dye Penetrant Test (DPT / LPT)

Detects micro surface cracking and porosity on critical machined seating surfaces.

Magnetic Particle Inspection (MPI)

For ferromagnetic alloys; flags surface and near-surface structural discontinuities.

Hardness Test (Brinell/Rockwell)

Verifies correct heat treatment structure and ensures mechanical properties are hit.

Direct-Reading Spectrograph

In-house lab chemical checks of billets before forging process begins.

Impact / Charpy Test

Crucial for low-temperature applications to verify ductility (e.g. A350 LF2, LTCS).

NACE Compliance Testing

Verifies sour-gas / H2S environment service capability (NACE MR0175 / MR0103).

Mill Test Certificate (MTC)

Provided as per EN 10204 3.1 detailing chemical & mechanical analysis.

EN 10204 3.2 Certificate

Independent third-party inspection validation (available upon request).

NACE MR0175 / MR0103 Compliance

Certified suitability for sour gas/H2S environments.

Raw Materials Certificate

Provides 100% trace origin tracking from steel billet to finished flange.

Dimensional Inspection Report

All critical tolerances checked and certified against CAD designs.

Heat Treatment Certificate

HTR and PWHT thermal chart records included where requested.

Hydrostatic Test Certificate

Pressure log documentation verifying weld integrity.

Third Party Inspection (TPI)

Bureau Veritas, SGS, Lloyds, DNV, TUV inspection options.

Packing List & Weight Certificate

Proper documentation for simple custom clearance and cargo log.

Country of Origin Certificate

Enables import tariff relief and compliance logging.

🔒 Certified Compliance Guaranteed
