ASTM A252:Spesifikasi Standar kanggo Tumpuk Pipa Baja Welded lan Seamless.
Spesifikasi iki nyakup tumpukan pipa baja tembok nominal (rata-rata) kanthi bentuk silinder lan ditrapake kanggo tumpukan pipa ing endi silinder baja tumindak minangka anggota beban permanen, utawa minangka cangkang kanggo mbentuk tumpukan beton cast-in-place.Tumpukan pipa diprodhuksi minangka produk sing dilas lan mulus.

Kelas ASTM A252
gelar ASTM A252 diklasifikasikaké minangka Grade 1 Grade 2 lankelas 3.
Proses Produksi Bahan Baku
Baja kudu digawe kanthi siji utawa luwih saka proses ing ngisor iki: open-hearth, dhasar-oksigen, utawa tungku listrik.
Bahan lan Pabrik
Tumpukan kudu digawe kanthi lancar, las tahan listrik, las kilat, utawa proses las fusi.
Jahitan tumpukan pipa sing dilas kudu longitudinal, helical-butt, utawa helical-lap.
Komposisi Kimia ASTM A252
Metode eksperimental: ASTM A751.
Baja kudu ngemot ora luwih saka 0,050% fosfor.Iki amarga tingkat fosfor sing dhuwur bisa nyebabake baja dadi rapuh ing suhu sing sithik, nyuda kekerasan materi kasebut.
Spesifikasi ASTM A252 duwe syarat winates kanggo komposisi kimia: iki amarga ASTM A252 ditrapake utamane kanggo aplikasi struktural, utamane minangka unsur beban, ing ngendi sifat fisik (kayata kekuatan ngasilake, kekuatan tarik, lan elongasi) luwih penting tinimbang komposisi kimia. .Sifat fisik kasebut bisa digayuh liwat proses manufaktur lan perawatan panas sing tepat tanpa kontrol komposisi kimia liyane kajaba fosfor.
Persyaratan Tarik ASTM A252
Metode eksperimen: ASTM A370.
Tes Tekanan Hidrostatik
Alesan ASTM A52 ora nemtokake tes hidrolik utamane amarga karakteristik aplikasi lan syarat desain pipa kasebut.
Kanggo tumpukan pipa baja ing spesifikasi ASTM A252, tujuan desain utama yaiku tahan beban aksial, dudu tekanan internal.Iki beda karo pipa kanggo transportasi cairan utawa gas, kayata ing spesifikasi API 5L, sing kudu ditindakake tes tekanan internal langsung kanggo mesthekake kekuwatan lan kekuwatane.

Cacat lumahing pipa
1. Cacat lumahing sing ambane ora ngluwihi 12,5% saka kekandelan tembok nominal sing ditemtokake bakal ditrima.
Iku bakal diijini kanggo netepake ambane imperfections kuwi dening grinding utawa filing.
2. Cacat lumahing sing nduweni ambane luwih saka 12,5% saka kekandelan tembok nominal sing ditemtokake bakal dianggep minangka cacat.
Kanggo cacat ora luwih jero tinimbang 33,3% saka kekandelan tembok nominal sing ditemtokake kanggo didandani kanthi welding, yen cacat wis rampung dibusak sadurunge welding.
