Baholar:GR.B, X42, X46, X52, X56, X60, X65, X70 X80
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
Qoplama:3PE qoplamasi, 3PP qoplamasi, FBE qoplamasi; Epoksi qoplamasi, maxsus bo'yoq
Ishlab chiqarish jarayoni:
• Ishlab chiqarish usuli: issiq prokat, sovuq kengaytirish (kengayuvchi bosh bilan payvand choki bilan aloqa qilishning oldini olish kerak)
• Yetkazib berish holati:
- N (normallashtirish)
- Q (kuch va qattiqlikni yaxshilash uchun söndürme + temperleme)
- M (termal prokat mashinasi)
• Maxsus ishlov berish: kislotaga chidamli quvur sulfid kuchlanishli korroziya sinovini o'tkazishi kerak, dengiz trubkasi kuchaytirilishi kerak
korroziyaga qarshilik
Oddiy dasturs:
• Yuqori bosimli gaz quvuri (-egiluvchan sinishga qarshi kengayish talablari)
• Chegara o'rtasida uzoq masofali quvur liniyasi (-45 daraja past haroratli muhit)
• Kislota neft va gaz koni (H2S muhiti NACEMR0175 ga javob berishi kerak)
• Dengiz osti quvurlari (Dengiz muhiti sertifikati J ilovasiga muvofiq)
Texnik talablardagi farqlar (PSL2 va PSL1):
• Kimyoviy tarkibni nazorat qilish: PSL2 uglerod ekvivalenti, mikroelementlar (oltingugurt, fosfor kabi) uchun yanada qattiqroq cheklovlarga ega va kislotaga chidamlilik yoki dengiz muhitining maxsus talablariga javob berishi kerak (masalan, H/J ilovasi).
• Mexanik xususiyatlar testi:
- Charpy ta'sirining majburiy sinovi (PSL1 buni talab qilmaydi)
- Asosiy material, payvand choki va issiqlikdan ta'sirlangan zona uchun qattiqlik sinovi talablari (HV10 Vickers yoki HR15N Rockwell)
- Dona oʻlchami va-metall boʻlmagan qoʻshimchalar uchun qoʻshimcha boshqaruv elementlari talab qilinadi
• Tekshirish chastotasi oshirildi: 100% buzmaydigan sinov (UT/RT), gidrostatik bosimni ushlab turish muddati uzaytirildi (25 soniya)
