Tes Hidrostatik
Pipa kasebut kudu tahan uji hidrostatik tanpa bocor liwat lapisan las utawa awak pipa
Jointers ora perlu hydrostatically dites, kasedhiya yen bagean pipa digunakake kanggo menehi tandha jointers kasil hydrostatically dites sadurunge operasi gabung.
Traceability:
Kanggo pipa PSL 1, pabrikan kudu netepake lan ngetutake prosedur sing didokumentasikake kanggo njaga:
Identitas panas nganti saben tes kimia sing gegandhengan ditindakake lan tundhuk karo syarat sing ditemtokake
Identitas unit tes nganti saben tes mekanik sing gegandhengan ditindakake lan selaras karo syarat sing ditemtokake ditampilake
Kanggo pipa PSL 2, pabrikan kudu netepake lan ngetutake prosedur sing didokumentasikake kanggo njaga identitas panas lan identitas unit uji kanggo pipa kasebut.Prosedur kasebut bakal nyedhiyakake sarana kanggo nglacak dawa pipa menyang unit tes sing tepat lan asil tes kimia sing gegandhengan.
