Spesifikasi PIPA ASME SA213 T22
Spesifikasi ASTM A / ASME SA 213 meliputi pipa baja feritik dan austenitic yang halus, superheater, dan tabung / tubing penukar panas. Beberapa nilai berisi huruf H dalam penunjukan mereka memiliki persyaratan yang berbeda dari nilai yang sama yang tidak mengandung huruf H. Persyaratan yang berbeda ini memberikan kekuatan creep-rupture yang lebih tinggi daripada yang biasanya dicapai dalam nilai yang sama tanpa persyaratan yang berbeda ini. Tabung harus dibuat dengan proses yang mulus dan harus selesai panas atau dingin, sebagaimana ditentukan. Grade TP347HFG harus dingin selesai. Perlakuan panas harus dilakukan secara terpisah dan selain pemanasan untuk pembentukan panas. Paduan feritik dan baja tahan karat feritik harus dipanaskan kembali. Di sisi lain, tabung stainless steel austenit harus dilengkapi dalam kondisi perlakuan panas. Sebagai alternatif, segera setelah pembentukan panas, sementara suhu tabung tidak kurang dari suhu larutan minimum, tabung dapat secara individual dipadamkan dalam air atau didinginkan dengan cepat dengan cara lain. Uji tegangan, uji kekerasan, uji merata, dan uji pembakaran harus dilakukan pada setiap tabung. Juga, setiap tabung harus dikenai uji listrik yang tidak rusak atau uji hidrostatik.
