ASTM A312 quvurlarni ishlab chiqarish turlari

• a. Choksiz quvur (SMLS): Choksiz quvur zanglamaydigan po'latdan yasalgan qattiq igna teshilishi orqali ishlab chiqariladi.
• b. Payvandlangan quvur (WLD): payvandlash vaqtida plomba metallini qo'shmasdan avtomatik payvandlash jarayonlari (qarshilik payvandlash, elektr termoyadroviy payvandlash) tomonidan ishlab chiqarilgan payvandlangan quvurlarni o'z ichiga oladi.
• c. Sovuq ishlov berilgan quvur (HCW trubkasi): Og'ir sovuq ishlangan quvur, har ikki devorda qalinligi kamida 35% dan kam bo'lmagan sovuq ishlov beriladi va oxirgi tavlanishdan oldin payvandlangan quvurga payvandlanadi. Payvandlash paytida plomba moddalarini ishlatmang.
