S690Q VS S690QL: "L" balandlikdagi "L" - quvvatli po'lat
(690 MPA ramzi|en 10025-6 standart)
Asosiy farq: past - Harorat qattiqligi
S690Q: Minimal ta'sir kuchayishi -20 darajali (o'rtacha 30j). → Odatda foydalanish: Tegishli iqlimlarning, karchilik uskunalari.
S690QL:-40 daraja va undan yuqori darajadagi (40j gacha katta yoki unga teng). → tanqidiy foydalanish: Arktika quvurlari, offshor platformalari, Sibirda tog'-kon avtomobillari.
Noto'g'ri ta'minlanganlik uchun xavf: S690Q -20 darajali xavfni kamaytirish (masalan, Kanada burg'ulash joyi) 2020 yilda qulashi mumkin.
Kimyoviy va ishlov berish farqlari

Nima uchun "L" real loyihalarda
Offshor shamol turbinalari: S690QL-yoğuralarda -30 darajadagi dengizlarda ishlatiladi (masalan, HornSea 2, Buyuk Britaniya). Moddiy muvaffaqiyatsizlik darajasi: S690Q uchun 0,2% vs 5%.
Narxlarning ta'siri: S690QL narxi 15% ga ko'p turadi, ammo 6-12 yilga, korroziy muhitda xizmat ko'rsatadi.
Payvandlash: S690QL vodorodni oldini olish uchun qat'iy qiziydi (150-250 daraja) ni talab qiladi.
Global standartlar va ekvivalentlar
Evropa (en 10025-6): S690Q===s690ql
China (GB/T 16270): S690Q ≈ Q690D / S690QL ≈ Q690E (stricter low-temp requirements)
AQSh (ASTM): A514 sinfiga teng (lekin majburiy -40 daraja sinovi yo'q).
Qaror nazorat ro'yxati
Agar S690Q ni tanlang:
- Operatsion templar> -20 darajasi
- Byudjet sezgirligi mavjud
- Qalinligi <40 mm (yo'q z {{{{{{{{{{{{{{{{{{{{{{{{{{- stressda)
S690QL-ga o'ting:
- Atrof atrofidagi yoki -40 darajadan kam yoki unga teng yoki teng bo'lgan
- Qalin plitalar (40 mm ga teng) derazani kechiktirish
- Vodorod ta'sir qilish (quvurlar, hg)
