Yuqori harorat uchun ASTM A335 qotishuv quvuri
Nov 05, 2025
A335 / A335M spetsifikatsiyasi yuqori {{}} yuqori {}} Haroratli xizmat uchun mo'ljallangan temirsiz po'latdan yasalgan quvurlar, shu jumladan nominal devor qalinligi va minimal devor qalinligi. Ushbu spetsifikatsiyaga buyurtma qilingan quvurlar bükmening, (gazni payvandlash) va shunga o'xshash shakllantirish operatsiyalari, shuningdek Fusion payvandlash uchun mos keladi. Tanlov dizayn, xizmat ko'rsatish sharoitlari, mexanik xususiyatlariga va yuqori - harorat xususiyatlariga asoslanadi.
