Flanesli birikma uchun qanday qilib zichlagich tanlash kerak?

Quyidagilarga asoslanib tanlang: flanes reytingi (150/300/600 va boshqa sinflar), quvur o'lchami (NPS), ish sharoitlari (harorat, bosim, muhit) va zichlagich turi (spiral o'ralgan, PTFE, rezina, metall). ASME B16.20 standart zichlagich o'lchamlarini belgilaydi.

Ko'tarilgan yuzali va halqa tipidagi birikma flaneslari o'rtasidagi farq nima?

Ko'tarilgan yuzali (RF) flaneslar ko'tarilgan sirtga o'rnatilgan tekis yoki spiral o'ralgan zichlagichlardan foydalanadi. Halqa tipidagi birikma (RTJ) flaneslari frezerlab ishlangan ariqchaga o'rnatiladigan metall halqa zichlagichlardan foydalanadi. RTJ yuqori bosimda ustunroq zichlash ta'minlaydi.

Zichlagichni o'rnatish kuchi nima?

Seating stress (y) is the minimum bolt stress required to initially seat the gasket and create a seal. It varies by gasket type: rubber ≈ 1.4 MPa, spiral wound ≈ 69 MPa, solid metal ≈ 180 MPa.

Flanesli birikma uchun qancha bolt qovushqoqligi kerak?

Bolt torque depends on bolt size, number of bolts, gasket type, and required seating stress. T = K × d × F/n, where K is nut factor (≈0.2 for lubricated), d is bolt diameter, F is total bolt load, n is number of bolts.

Qachon spiral o'ralgan zichlagichdan foydalanish kerak?

Spiral wound gaskets (ASME B16.20) are the most versatile choice for raised face flanges in process piping. Suitable for temperatures from -200°C to 600°C (depending on filler), pressures up to Class 2500, and most chemical services.
