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
Korroziyaga chidamlilik va qoplama:
- Gr.B ning oʻzi korroziyaga chidamliligiga ega boʻlsa-da, muayyan muhitlarda xizmat muddatini uzaytirish uchun korroziyaga qarshi qoʻshimcha ishlov berish yoki qoplama talab qilinishi mumkin.
- qoplama: 3PE qoplama, 3PP qoplama, FBE qoplama;Epoksi qoplama, maxsus bo'yash
Amaldagi muhit:
Yuqori bosim, yuqori harorat, past harorat yoki korroziy muhitga bardosh berishi kerak bo'lgan quvur quvurlari tizimlari uchun, ayniqsa ekstremal iqlim sharoitida uzoq masofalarga-neft va gazni tashish uchun javob beradi.
Ishlab chiqarish jarayoni:
Murakkab o'rnatish va payvandlash talablariga javob beradigan po'lat quvurlarning yaxshi mustahkamligi va payvandlanishini ta'minlash uchun issiq haddeleme yoki sovuq ishlov berish orqali amalga oshiriladi.
Muhandislik dasturi:
U neft va tabiiy gazni qazib olish, qayta ishlash va tashishda hal qiluvchi rol o'ynaydi, shuningdek, suv o'tkazish va ayrim sanoat quvurlari tizimlari va boshqalar uchun qo'llaniladi.
