ASTM A671 Atmosfera va past haroratlar uchun elektr termoyadroviy payvandlangan po'lat quvurlar uchun standart spetsifikatsiya
ASTM A671 standart spetsifikatsiya bo'lib, to'ldiruvchi metall qo'shilgan, bir nechta tahlillar va quvvat darajalariga ega bosimli idishning sifat plitasidan ishlab chiqarilgan va atmosfera va past haroratlarda yuqori bosimli xizmat ko'rsatish uchun mos bo'lgan elektr termoyadroviy payvandlangan po'lat quvurlarni qamrab oladi. Istalgan xususiyatlarga erishish yoki amaldagi kod talablariga rioya qilish uchun issiqlik bilan ishlov berish talab qilinishi mumkin yoki bo'lmasligi mumkin. Qo'shimcha test yoki tekshiruv zarur bo'lganda foydalanish uchun qo'shimcha talablar taqdim etiladi.
Spetsifikatsiya nominal sifatida tashqi diametri 16 dyuym [400 mm] yoki undan katta va devor qalinligi 1/4 dyuym [6 mm] yoki undan katta bo'lgan quvurni qamrab oladi. Boshqa o'lchamlarga ega bo'lgan quvurlar, agar u ushbu spetsifikatsiyaning barcha boshqa talablariga javob bersa, jihozlanishi mumkin.
