| Tashqi diametri | 6 - 610 mm |
| Devor qalinligi | 0,5 - 30 mm, o'rtacha devor yoki minimal devor |
| Uzunligi | Muayyan yoki RANDO, Standart 6000 mm uzunlik |
| Shart | Tuzni yopish, yaxshi eslash |
| Shakl: | Dumaloq, o'ralgan naycha |
| Ariza | Issiqlik birja, qozon, suv, yuqori bosim, manzaralar |
| Ishlab chiqarish usuli | Sovuq siljish, sovuq chizilgan |
ASTM A789 / A789M spetsifikatsiyasi nominal devor qalinligi navlari va umumiy korroziyaga qarshi kurashishga yordam beradigan xizmatlarga zanglamaydigan po'latdan yasalgan stakanni qamrab oladi. Agar ko'tarilgan haroratda uzoq vaqt davomida ishlatilgan bo'lsa, bu po'latlar qulab tushadi.
Issiqlik va mahsulot tahlillari, po'lat uglerod, marganets, oltingugurt, kremniy, nikel, xrom, molibden, azot, mis va boshqalar uchun kerakli kimyoviy tarkibga muvofiq amalga oshiriladi.
Barcha quvurlar, belgilangan harorat va shkaf sharoitidan so'ng tozalangan holatda saqlanadi. Davomiy issiqlikning oxirgi davri doimiy idishga yoki issiq isitmada bo'lsa, suyuqlikni isitmadan so'ng, bir xil o'lchamdagi naychalar va bir xil issiqlikdagi naychalar sonidan keyin va ko'p miqdordagi naychalardan ajratilgandan keyin olinadi.
Materiallar belgilangan tanglik va qattiqlik xususiyatlariga mos keladi. Buzilish testi, alangasiz test (choksiz naychalar uchun), flaning testi, qattiqlik sinovi, qattiqlikni tekshirish va teskari test sinovlari kabi mexanik sinovlar, po'lat quvurda amalga oshiriladi. Har bir naycha, shuningdek, numostrerdengr ta'sirli sinov yoki gidrostatik testga duchor bo'ladi.
ASTM A789 S31803 materiallari
ASTM A789 S31803 - bu 21% - 23% xrom, 2,5% - 3,5% molibden, 4,5-6,5% nikel va azot qotishmasi. Bu mahalliy kuch xususiyatlariga qo'shimcha ravishda mahalliylashtirilgan va stress korroziyaga chidamliligini ta'minlaydi.
ASTM A789 S32205 Material
ASTM A789 S32205, 22% - 23% xrom, 3,5-6,5% nikel va 0,08% azot qotishmasi. Odatda bu S31803 bilan ikki xil.
ASTM A789 S32750 Material
ASTM A789 S32750 - 24% - 5% xromi, 3% - 8% nomency, Super Dupsuvi 2507 va F53 ekvivalent navlar mavjud.
ASTM A789 S32760
ASTM A789 S32760 - 24% - 4% xrom, 3% - 4% moliblen, 6% - 8% nikel navi, F55 va 1,4501 tasi ekvivalent hisoblanadi.
