Inspeksi Produk
1. Pemeriksaan Komposisi Kimia
Chemical composition inspection is carried out to confirm the chromium, nikel, carbon and other alloying elements comply with ASTM A182 F310 or F310S requirements. Spectrometer analysis is used to verify the material grade before and during production, helping ensure the flange provides the intended corrosion resistance, oxidation resistance and traceable compliance with project specifications.
2. Pengujian Sifat Mekanik
Mechanical testing verifies that the flange material meets required tensile strength, kekuatan hasil, elongation and hardness values after heat treatment. Testing is performed according to the applicable material standard and provides assurance that 310 stainless steel lap joint flanges have the strength and ductility needed for industrial piping service at ambient and elevated temperatures.
3. Inspeksi Dimensi
Inspeksi dimensi memeriksa diameter luar, ketebalan, membosankan, lingkaran baut, ukuran lubang baut, hole quantity and facing details against the selected flange standard. Untuk flensa sambungan pangkuan, close attention is given to fit-up with the stub end and free-rotating alignment, ensuring easy installation, proper bolting and reliable sealing performance in service.
4. Pengujian PMI dan Pengujian Hidrostatis
PMI testing confirms positive material identification of 310 or 310S stainless steel to avoid grade mix-up in critical applications. Hydrostatic testing is generally conducted at the piping assembly or system level, while flange supply includes visual and dimensional verification. EN 10204 3.1 sertifikat, heat number traceability and inspection records are provided to support quality documentation requirements.

Pertanyaan Umum
Q: Apa itu a 310 stainless steel lap joint flange?
A: A 310 stainless steel lap joint flange is a loose backing flange used together with a stub end to form a flanged piping connection. Unlike weld neck or slip on flanges, it rotates freely around the stub end, making bolt hole alignment easier. It is chosen for systems requiring frequent dismantling, good corrosion resistance and elevated-temperature performance.
Q: What materials are available for 310 flensa sambungan pangkuan baja tahan karat?
A: SASA FLANGE mainly supplies ASTM A182 F310 and F310S lap joint flanges, sesuai dengan UNS S31000 and S31008. Equivalent international grades such as EN 1.4841, EN 1.4845, SUS310S and comparable GB grades can also be produced. Material selection depends on operating temperature, lingkungan korosi, standard requirement and customer project specification.
Q: Kelas tekanan apa yang didukung?
A: Untuk 310 flensa sambungan pangkuan baja tahan karat, kisaran pasokan umum adalah Kelas ASME 150, 300 Dan 600, with EN pressure ratings such as PN10, PN16, PN25 dan PN40. Larger diameters are usually made in lower pressure ratings due to lap joint design practice. Higher ratings can be reviewed according to size, standard and project requirements.
Q: Bisa SASA FLANGE menyediakan ukuran khusus?
A: Ya. SASA FLANGE can produce custom lap joint flanges based on drawings or technical specifications, including non-standard outside diameter, ukuran lubang, bolt hole drilling, thickness and marking requirements. We can also match the flange to specific stub end dimensions, sealing face details and international standards such as ASME, EN, DIN, JIS and GB.
Q: Sertifikat apa yang diberikan?
A: SASA FLANGE dapat menyediakan EN 10204 3.1 material certificate together with mill test report, heat number traceability and inspection records. Additional documentation such as PMI test results, dimensional inspection report and mechanical test report can be supplied as required. Hydrostatic testing is typically system-based, but supporting quality documents for flange compliance are available.
