ASTM A106 Chapper trubkasi
ASTM A106 - bu - yuqori martabali xizmatda ishlatiladigan choksiz uglerod po'lat pyuresi uchun standart spetsifikatsiya.
AsTM A106 po'lat quvurlari asosan uch navni qamrab oladi: A sinfi, B sinflari va C.11 sinfi va turli xil dasturlarni o'z ichiga olgan turli xil dasturlarga mos keladigan kimyoviy tarkibi va mexanik xususiyatlari bilan ajralib turadi.
Odatda C va B sinflar bilan taqqoslaganda, yuqori darajadagi va b sinflar bilan taqqoslaganda, ko'p talab qilinadigan yuqori - bosim bilan taqqoslaganda, u kamroq og'ir sharoitlarda ko'p iste'mol qilish uchun yuqori darajada kuchayib boradi.
