Detil Produk
Paduan 20 lap joint flanges are loose backing flanges used together with alloy 20 stub ends to create a practical flange connection for piping systems that require frequent dismantling, alignment flexibility and strong resistance to acidic media. Compared with welding neck or slip on designs, the lap joint type reduces flange contact with process fluid while maintaining convenient assembly. It is commonly specified for chemical processing, sulfuric acid handling, pickling lines, pharmaceutical plants and marine systems.

Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical analysis is carried out to verify that the alloy 20 material meets the required composition range for chromium, nikel, molibdenum, copper and niobium, along with controlled carbon, sulfur and phosphorus levels. This inspection confirms the corrosion-resistant grade before machining and shipment, and results are referenced in the material certificate.
2. Pengujian Sifat Mekanik
Mechanical testing is performed according to the applicable material standard to confirm tensile strength, kekuatan hasil, nilai perpanjangan dan kekerasan. These tests help ensure the flange material has suitable strength and ductility for fabrication and service. Test results are reviewed against ordered requirements and retained for quality documentation.
3. Inspeksi Dimensi
Each alloy 20 lap joint flange is checked for outside diameter, membosankan, ketebalan, lingkaran baut, bolt hole quantity and hole diameter according to the specified standard. The seating surface and overall flatness are also inspected to ensure proper fit-up with the stub end and accurate field assembly during installation.
4. Pengujian PMI dan Pengujian Hidrostatis
PMI testing is available on each flange to verify alloy identity and prevent material mix-up in nickel alloy projects. Lap joint flanges are not pressure-containing by themselves, so hydrostatic testing is generally applied to the assembled piping system rather than the loose flange alone. EN 10204 3.1 sertifikat, MTC and inspection reports can be supplied.

Pertanyaan Umum
Q: Apa itu paduan 20 flensa sambungan pangkuan?
A: Sebuah paduan 20 lap joint flange is a loose backing flange used together with an alloy 20 ujung rintisan. The flange does not contact the process medium directly in the same way as an integral flange face, which helps reduce cost in some designs while allowing easy alignment, quick dismantling and good corrosion performance in aggressive chemical piping systems.
Q: Bahan apa yang tersedia untuk paduan 20 flensa sambungan pangkuan?
A: The main material is ASTM B462 UNS N08020, also known as Alloy 20 or Carpenter 20 equivalent. Depending on project requirements, SASA FLANGE can also offer matching stub ends and related corrosion-resistant flange products in stainless steel, baja tahan karat dupleks, nickel alloys and other special materials with full traceability and certified documentation.
Q: Kelas tekanan apa yang didukung?
A: For alloy 20 flensa sambungan pangkuan, kisaran pasokan umum adalah Kelas ASME 150, 300 Dan 600, with selected EN and DIN pressure ratings such as PN10, PN16, PN25 and PN40. Higher-pressure designs are reviewed according to size, standar, material availability and the mating stub end configuration required by the piping system.
Q: Bisa SASA FLANGE menyediakan ukuran khusus?
A: Ya. SASA FLANGE can supply custom alloy 20 flensa sambungan pangkuan berdasarkan gambar atau spesifikasi proyek, including non-standard drilling, ukuran lubang khusus, customized dimensions, special facing requirements and matched stub ends. Kami mendukung ASME, EN, DIN, JIS and GB dimensions as well as OEM machining for skid fabricators, EPC contractors and end users.
Q: Sertifikat apa yang diberikan?
A: SASA FLANGE dapat menyediakan EN 10204 3.1 sertifikat materi, sertifikat uji pabrik, ketertelusuran nomor panas, dimensional inspection reports and PMI records for alloy 20 flensa sambungan pangkuan. Additional documentation can be arranged according to order requirements. For assembled pressure systems, hydrostatic test records are generally issued at piping or system level rather than for the loose flange itself.
