5. Mandatory Testing Procedures

The integrity of Monel 400 fittings is ensured through a series of mandatory tests outlined in ASTM B366 / ASME SB366.

ある) Visual and Dimensional Inspection

All fittings are checked for surface quality, 寸法, and geometry. Surface defects such as cracks, pits, or laps are strictly prohibited. Precision measuring tools verify critical dimensions against ASME B16.9 or B16.11 standards.

b) 非破壊検査 (NDT)

SASAFLANGE uses advanced NDT techniques to detect any internal or surface flaws without damaging the fitting:

• 超音波検査 (ユタ州): Identifies internal discontinuities or voids.

• 染料浸透試験 (PT): Detects surface cracks or porosity.

• 放射線検査 (RT): Used for weld seam examination in welded fittings.

c) Hydrostatic or Pneumatic Testing

Fittings are pressurized with water or air to verify leak-tight performance under simulated service conditions. This test ensures that the joint integrity meets specified design pressures.

d) Mechanical Tests

Samples from each batch are tested for 抗張力, 降伏強さ, elongation, and hardness. These tests confirm that the fittings possess adequate strength and flexibility for installation and operation.

e) 粒界腐食試験 (IGC)

For certain applications, モネル 400 may also undergo IGC testing to verify resistance to grain boundary attack in corrosive environments.

6. Heat Treatment and Microstructure Control

After forging or forming, モネル 400 fittings must be annealed at temperatures between 870°C and 980°C, followed by controlled cooling. This heat treatment:

• Relieves internal stresses from forging or welding.

• Restores ductility and improves corrosion resistance.

• Ensures uniform grain structure and mechanical stability.

SASAFLANGE uses computer-controlled furnaces with precise temperature monitoring to maintain consistent annealing results across all product batches.

7. Certification and Documentation Requirements

Certification provides traceability and assurance of product quality. Under ASTM B366 / ASME SB366, every batch of Monel 400 fittings must be supplied with complete documentation, 含む:

• ミルテスト証明書 (MTC) in accordance with EN 10204 タイプ 3.1.

• Chemical analysis report confirming alloy composition.

• Mechanical test results (引張, 収率, elongation).

• NDT and pressure test reports.

• Heat treatment records.

• Dimensional inspection report.

SASAFLANGE maintains a comprehensive quality documentation system, enabling full traceability from raw material to final product. Each certificate is digitally archived and made available to clients for audit or project submission.

8. Compliance with Additional Standards

In addition to ASTM B366 / ASME SB366, モネル 400 fittings from SASAFLANGE can be supplied according to complementary standards when required:

• ASME B16.9 / B16.11: Dimensions and tolerances for butt-weld and forged fittings.

• NACE MR0175 / ISO 15156: Material qualification for sour gas and H₂S-containing environments.

• PED 2014/68/EU: Pressure Equipment Directive compliance for European installations.

• ISO 9001:2015: Quality management system certification.

These multiple levels of certification ensure that SASAFLANGE products are globally accepted for critical process applications.
