説明
製品詳細
Hastelloy threaded flanges are forged or machined flanges with female pipe threads that connect directly to threaded pipe without welding. They are widely used in corrosive chemical lines, acid handling systems, instrumentation connections, small-bore process piping and maintenance-sensitive plants where hot work should be minimized. Key advantages include excellent corrosion resistance, reliable assembly, easy replacement and suitability for moderate to high pressure service depending on design standard.
SASA FLANGE supplies Hastelloy threaded flanges in standard and customized sizes with precision machining for NPT, BSPT or BSPP threads. Each order can be supported by chemical analysis, 機械的試験, 寸法検査, PMIテスト, EN 10204 3.1 certificate and full heat number traceability. カスタムドリル, 直面している, special marking and project documentation are available for international industrial buyers.

製品検査
1. 化学成分検査
Chemical composition inspection verifies that the nickel alloy flange matches the specified Hastelloy grade such as C276 or C22. Samples are checked by spectrometer or laboratory analysis for key elements including nickel, クロム, モリブデン, tungsten and iron. This confirms compliance with applicable alloy standards and supports reliable corrosion performance in aggressive service conditions.
2. 機械的特性試験
Mechanical testing confirms that supplied Hastelloy flange material meets required tensile strength, 降伏強さ, elongation and hardness values. Testing is performed according to relevant ASTM or ASME requirements using representative material from the production lot. These checks help ensure the flange can withstand assembly loads, pressure service and operating stresses in demanding industrial environments.
3. 寸法検査
Dimensional inspection covers outside diameter, 厚さ, hub profile where applicable, ボルトサークル, ボルト穴のサイズ, face finish and thread accuracy. For threaded flanges, thread form and depth are checked using calibrated gauges to ensure proper fit-up with mating pipe. Precise inspection helps avoid leakage, alignment problems and installation delays at the project site.
4. PMI試験と静水圧試験
PMI testing is carried out to confirm the supplied flanges are the correct Hastelloy alloy and not mixed with stainless steel or other nickel materials. Hydrostatic or pressure-related verification can be arranged according to project scope and applicable standards.
