Gwosè:
Eksteryè Dyamèt Range: 1/2 "a 2", 3", 4", 6", 8", 10", 12"
Orè epesè: SCH 10,SCH20, SCH40, SCH STD, SCH80
Nivo spesifikasyon pwodwi (PSL):
- PSL1: Kondisyon debaz pou aplikasyon estanda.
- Diferans kle ak PSL2:
- Kontwòl konpozisyon chimik mwens sevè.
- Pa gen okenn tès enpak obligatwa Charpy V-notch (opsyonèl sòf si yo espesifye).
- Pi ba limit maksimòm ekivalan kabòn (CE) pou soudabilite.
- Akseptab pou anviwònman sèvis jeneral, ki pa-asid.
Pwosesis Faktori:
- San pwoblèm: Cho-woule oswa frèt-desine.
- Welde: Elektrik Rezistans Soude (ERW) oswa Submerged Arc Welded (SAW).
Kondisyon pou Tès (PSL1):
- Tès idrostatik: Obligatwa (presyon tès ki baze sou epesè miray ak dyamèt).
- Tès ki pa-destriktif (NDT): Obligatwa pou kouti soude nan tiyo soude.
- Tès si ou vle: Tès enpak, dite, oswa tès koube (si achtè espesifye).
Aplikasyon:
- Tiyo transmisyon lwil/gaz sou rivaj.
- Liy piki dlo.
- Ba-sistèm rasanbleman presyon.
- Aplikasyon estriktirèl (egzanp, pile).
Konsiderasyon kle:
- Anviwònman: Pa apwopriye pou sèvis asid (anviwònman H₂S) sof si kondisyon siplemantè (egzanp, NACE MR0175) yo satisfè.
- Soudi: Swiv estanda API 1104; prechofe ka bezwen akòz CE.
- Pwoteksyon korozyon: Kouch (pa egzanp, FBE, 3LPE) oswa pwoteksyon katodik yo mande yo souvan.
