Ürün Detayı
Hastelloy lap joint flanges are backing flanges designed to be used with a compatible stub end, allowing easy alignment and dismantling in piping systems handling highly corrosive media. Compared with integral flanges, the lap joint design reduces replacement cost in alloy piping because the flange does not contact the process fluid directly when matched with the correct stub end material. These flanges are widely used in chemical plants, açık deniz platformları, flue gas treatment, acid service and high-purity process lines.
SASA FLANGE supplies Hastelloy lap joint flanges in standard and customized dimensions according to ASME, EN, DIN, JIS, GB ve proje çizimleri. Each batch can be delivered with chemical analysis, mekanik test, boyutsal muayene, PMI testi, EN 10204 3.1 Kritik endüstriyel tedarik gereksinimlerini desteklemek için sertifika ve tam ısı numarası izlenebilirliği.

SSS
Q: What is a Hastelloy lap joint flange?
A: A Hastelloy lap joint flange is a loose backing flange used together with a lap joint stub end. The flange can rotate around the stub end, making bolt hole alignment easier during installation. In corrosive alloy piping systems, this design can reduce cost and simplify maintenance because only the wetted stub end needs to match the process fluid.

A: SASA FLANGE can supply Hastelloy lap joint flanges in common nickel alloy grades including Hastelloy C22, Hastelloy C276, Hastelloy B2 and Hastelloy C2000. Material selection depends on the process medium, sıcaklık, corrosion mechanism and project specification. We can also discuss equivalent UNS grades and matching stub end materials for complete assembly supply.
Q: Hangi basınç sınıfı destekleniyor?
A: We can supply Hastelloy lap joint flanges in ASME Class 150, 300, 600, 900, 1500 Ve 2500, as well as EN and other metric pressure ratings such as PN10 to PN100 depending on size and standard. Large diameter flanges can also be produced to ASME B16.47 or customer drawings for project-specific piping systems.
Q: Olabilmek SASA FLANGE özel boyutlar sağlayın?
A: Evet. SASA FLANGE can manufacture custom Hastelloy lap joint flanges based on project drawings or non-standard requirements. We support special drilling patterns, custom outside diameter, special bore, matching dimensions for stub ends, metric or inch standards, and tailored marking. Custom machining and documentation packages are available for EPC, OEM and maintenance buyers.
Q: Hangi sertifika veriliyor?
A: Hastelloy lap joint flanges can be supplied with EN 10204 3.1 malzeme sertifikası, değirmen test sertifikası, dimensional inspection report and PMI test results. Additional documentation can be arranged according to order requirements. Where specified, we also support third-party inspection, hardness or mechanical test records, heat number traceability and complete shipping marking for project control.
