Baholar:GR.A, GR.B, X42, X46, X52, X56, X60, X65, X70
O'lchamlari:
Tashqi diametr diapazoni: 1/2 "dan 2", 3", 4", 6", 8", 10", 12" gacha
Qalinlik jadvali: SCH 10, SCH20, SCH40, SCH STD, SCH80
Mahsulot spetsifikatsiyasi darajasi (PSL):
- PSL1: Standart ilovalar uchun asosiy talablar.
- PSL2 dan asosiy farqlari:
- Kimyoviy tarkib nazorati kamroq.
- Charpy V-ta'sirini majburiy sinovdan o'tkazilmaydi (agar belgilanmagan bo'lsa, ixtiyoriy).
- Payvandlash uchun maksimal uglerod ekvivalenti (CE) chegaralari past.
- Umumiy, nordon boʻlmagan{1}}xizmat muhitlari uchun ruxsat etiladi.
Ishlab chiqarish jarayonlari:
- Uzluksiz: issiq{1}}o‘ralgan yoki sovuq{2}}chizilgan.
- Payvandlash: Elektr qarshilik payvandlangan (ERW) yoki suv ostida payvandlangan (SAW).
Sinov talablari (PSL1):
- Gidrostatik sinov: Majburiy (devor qalinligi va diametri asosida sinov bosimi).
--Buzuvchisiz sinov (NDT): Payvandlangan quvurlardagi payvand choklari uchun talab qilinadi.
- Ixtiyoriy sinovlar: zarba sinovi, qattiqlik yoki egilish sinovlari (agar xaridor tomonidan belgilab qo'yilgan bo'lsa).
Ilovalar:
- Quruqlikdagi neft/gaz uzatish quvurlari.
- Suv quyish liniyalari.
- Past-bosim yig‘uvchi tizimlar.
- Strukturaviy ilovalar (masalan, qoziq).
Asosiy fikrlar:
- Atrof-muhit: Agar qo'shimcha talablar (masalan, NACE MR0175) bajarilmasa, nordon (H₂S muhitlari) uchun mos emas.
- Payvandlash: API 1104 standartlariga rioya qiling; Idoralar tufayli oldindan isitish kerak bo'lishi mumkin.
- Korroziyadan himoya: qoplamalar (masalan, FBE, 3LPE) yoki katodik himoya ko'pincha talab qilinadi.
