Инколой 825 / Сплав 825 Flanges – ASTM B564 UNS N08825
Кованый сплав 825 фланцевые решения для выбранной кислоты, контроль загрязнения, oil-and-gas and chemical-process systems requiring UNS N08825.
Quick engineering answer
Инколой 825 and Alloy 825 are established names for UNS N08825, a nickel-iron-chromium alloy containing molybdenum and copper. For forged flanges, the procurement identity is ASTM B564 UNS N08825. “Inconel 825” appears in searches, but it is not the preferred grade name.
Product specification
| Материал | ASTM B564 UNS N08825 nickel-iron-chromium alloy |
|---|---|
| Available forms | Приварная горловина, слепой, без шнуровки, раструбная сварка, резьбовой, коленный сустав, orifice and drawing-specific flanges where permitted |
| Dimensional standards | ASME B16.5; ASME B16.47 for applicable large diameters; EN 1092-1 or approved drawings on request |
| Pressure classes | Сорт 150, 300, 400, 600, 900, 1500 и 2500 within the selected standard, material group and size limits |
| Облицовка | Поднятое лицо (РФ), Кольцевое соединение типа (РТЖ), Плоское Лицо (ФФ) where permitted, or drawing-specific facing |
| Документация | EN 10204 3.1 МТС, прослеживаемость плавки, dimensional report and ordered inspection records |
Pressure-temperature ratings depend on the governing code, flange standard edition, группа материалов, размер и класс. Confirm the complete project specification before ordering.
Grade and terminology check
| Preferred page name | Инколой 825 / Сплав 825 Фланцы | Supports both recognized purchasing terms |
|---|---|---|
| Formal material identity | ASTM B564 UNS N08825 | EN 2.4858 is a commonly cross-referenced designation |
| Common search variant | Инконель 825 фланцы | Clarify the terminology instead of using it as the primary product name |
Выбор материала
Сплав 825 is selected for useful resistance in several reducing and oxidizing acid environments, but service suitability is conditional. Медиахимия, acid concentration, хлориды, impurities, аэрация, температура, crevices and welding history require review.
Matching-material note: Match the exact UNS N08825 product-form specification for pipe, fittings and other adjoining components. A common alloy family name does not replace the standard required for each product form.
Quality controls available
- PMI with heat-number traceability
- EN 10204 3.1 сертификат материала
- Intergranular, corrosion or NDE testing when specified
- Размеры, facing finish and visual inspection
Типичные применения
Applications are selection cues, not blanket approvals. Process media, давление, температура, corrosion data, fatigue, fabrication and code requirements govern final suitability.
Standards hierarchy
Информация, необходимая для предложения
Provide the material grade, тип фланца, стандарт и издание, НПС или DN, pressure class or PN rating, график труб или точный диаметр отверстия, facing and finish, количество, delivery destination, термическая обработка, ОСП, тестирование, certification and third-party inspection requirements.
Часто задаваемые вопросы
Should buyers specify Inconel 825 or Incoloy 825?
Use Incoloy 825 or the generic name Alloy 825, and place ASTM B564 UNS N08825 on the purchase order. This avoids ambiguity regardless of the commercial trade name used in a search.
Which flange styles are available?
Depending on size, класс и стандарт, supply can include weld neck, слепой, без шнуровки, socket-weld, резьбовой, lap-joint, orifice and drawing-specific flanges.
What documentation can be supplied?
Typical documentation includes an EN 10204 3.1 МТС, heat traceability and dimensional report. PMI, ОСП, corrosion testing and third-party inspection can be added when specified before manufacture.
Request a specification review and quotation
Send the complete RFQ or piping material specification. SASA FLANGE will review grade identity, размеры, лицом к лицу, inspection and documentation before production.
