Baholar:GR.B, X42, X46, X52, X56, X60, X65, X70 X80
O'lchamlari:
Chiqish diametri diapazoni: 1/2 dyuym --- 24 dyuym
Devor qalinligi diapazoni: SCH10, SCH20, SCH40, SCH STD, SCH80
Uzunligi: 1m---18m
Qoplama:3PE qoplamasi, 3PP qoplamasi, FBE qoplamasi; Epoksi qoplamasi, maxsus bo'yoq
Mexanik xususiyatlar:
- Majburiy sharoitlarda J-B usuli yordamida zarba sinovi (past haroratli muhit uchun -20 darajadan past-qo‘shimcha sinov talab qilinadi).
- Qattiqlik sinovi asosiy metall, payvand choki va issiqlik ta'sirlangan zonani qamrab oladi; choksiz quvurlar uchun to'liq quvur tanasi sinovi talab qilinadi).
- Donalarning oʻlchami va qoʻshimchalari egiluvchan yoriqlar tarqalish talablariga javob berishi kerak (ayniqsa, gaz uzatish quvurlari uchun).
Ishlab chiqarish usuli:Choksiz quvurlar asosan issiq haddeleme bilan ishlab chiqariladi va diametri sovuq kengaytirilishi mumkin; payvandlangan quvurlar yuqori-aniqlikdagi payvandlash texnikasini talab qiladi (masalan, SAWL/SAWH).
Yetkazib berish sharti:
- Q (söndürme + temperleme): Quvvat va mustahkamlikni oshiring (masalan, X70Q).
- M (issiq mexanik prokat): Chuqur dengiz yoki o‘ta sovuq muhitlar uchun mos-to‘liq ish faoliyatini optimallashtiring.
Ilovalar:
- Yuqori bosimli gaz uzatish magistral liniyalari (ish bosimi 15 MPa dan yuqori yoki unga teng).
Polar yoki chuqur{0}}dengiz neft va gaz quvurlari (-45 daraja past harorat va yuqori tuz korroziyasiga bardosh bera oladi).
- Tarkibida vodorod sulfidi boʻlgan kislotali neft va gaz konlari.
- Yuqori bosimli-shahar gaz taqsimlash tarmoqlari (xavfsizlik va tejamkorlikni hisobga olgan holda).
