Pipa Baja ASTM A519
Pipa iki isine sawetara gelar saka karbon lan baja alloy tubing mechanical, salah siji panas-rampung utawa kadhemen-rampung.Baja sing digunakake ing pipa mekanis bisa dibuwang ing ingot utawa bisa dadi untaian.Nalika baja saka macem-macem gelar wis sequentially untaian cast, identifikasi saka asil materi transisi dibutuhake.Tubing mulus minangka produk tubular sing digawe tanpa jahitan sing dilas.Biasane diprodhuksi dening baja kerja panas, lan yen perlu, kanthi kadhemen ngrampungake produk tubular sing digawe panas kanggo ngasilake wangun, dimensi lan sifat sing dikarepake.
Tabung kudu dilengkapi ing wangun ing ngisor iki: babak, kothak, persegi dowo lan bagean khusus.Analisis panas kudu ditindakake kanggo nemtokake persentase unsur sing ditemtokake.Yen pangolahan leleh sekunder digunakake, analisis panas kudu dijupuk saka siji ingot remelted utawa produk saka siji ingot remelted saben leleh utama.Pipa kasebut kudu dilapisi film lenga sadurunge dibentuk kanggo nyegah karat nalika ditemtokake
