A335 P91 Tavsif:
1) A335P91 yuqori bosim va yuqori haroratga chidamli po'latdan yasalgan materialdir. P91 barlari, plitalari, quvurlari, quvur qismlari, p91 odatda
A355P91 deb ataladi, bu milliy standart 10Cr9Mo1VNb ga teng. Bu yuqori bosim va yuqori haroratli materialdir
chidamli po'lat quvurlar. Amerika standarti ASME SA-335/SA335M, valentlik kuchi ≥ 585 (MPa), oqish quvvati
≥ 415 (MPa), uzayishi esa ≥ 20 (%) ga teng. P91 ning xarakteristikasi shundaki, trubaning devor qalinligi ingichka. Xususida
material iste'moli, u boshqa po'lat materiallarga qaraganda 40% dan ko'proq kamroq va tejash jihatidan 30% dan ortiq kamroq.
materiallar va o'rnatish xarajatlari. P91 trubasining o'lik og'irligi kamayganligi sababli, tayanchlar va ilgichlarning yuki ham nisbatan bo'ladi
qisqartirilgan, bu qo'llab-quvvatlash va ko'tarish uchun qulay va dizayn va o'rnatish uchun qulay.
2) T91/P91 (10Cr9Mo1VNb) va P91 po'latining mos keladigan nemis po'lati X10CrMoVNNb91, yapon po'lati hisoblanadi.
- HCM95, frantsuz po'lati - TUZ10 CDVNb0901.
3) Devor harorati ≤ 625 ℃ bo'lgan yuqori haroratli o'ta qizdirgich va isitgich uchun po'lat quvurlar sifatida ishlatilishi mumkin.
o'ta kritik qozonlar, shuningdek devor harorati ≤ 600 ℃ bo'lgan yuqori haroratli sarlavha va bug 'quvurlari, shuningdek yadroviy elektr
issiqlik almashtirgich va yog 'kreking birligi o'choq quvurlari.

Ilova:
Qotishma quvurlar asosan past va o'rta bosimli qozonlarning sirt quvurlarini isitish uchun ishlatiladi (ish bosimi odatda
5.88Mpa dan yuqori emas va ish harorati 450 ℃ dan past); U sirt quvurlarini, iqtisodchilarni,
yuqori bosimli qozonlarning o'ta qizdirgichlari, qayta isitgichlari, neft-kimyo sanoati uchun quvurlar va boshqalar (ish bosimi odatda
9,8Mpa dan yuqori va ish harorati 450 ℃ dan 650 ℃ gacha)
