Flange Connection Rating

For Tri-Clamps, the maximum pressure is 16 bar for 1.5 in. (37.5 mm) and 2 in. (50 mm) housing; and 10 bar for 3 in. (75 mm) and 4 in. (100 mm) housing. The final rating depends on the clamp and gasket you are using. Tri-Clamp is available for the Standard Temperature and Pressure seal.

Flange strength calculations are made with the following conditions:

•For 316L SST:

	Bolting material		Gasket		Flange material	Hub material
		Standard/HTHP		HP/HTHP/C
ANSI	Stainless steel SA193	Soft (1a) with min.		Spiral wound gasket with
	B8M C1.2	thickness 1.6 mm.		nonmetallic filler (1b)	Stainless steel A182	Stainless steel A479M
	EN 1515-1/-2 group	Soft (EN 1514-1) with		Spiral wound gasket with	Gr. F316L and	316L or
EN				nonmetallic filler	EN 10222-5-1.4404.	EN 10272-1.4404.
	13E0, A4-70.	min. thickness 1.6 mm.
				(EN 1514-2)

•For Alloy C-276:

	Bolting material		Gasket		Flange material	Hub material
		HTHP		HP/HTHP/C
ANSI		Soft (1a) with min.		Spiral wound gasket with	SB462 Gr. N10276
		Thickness 1.6 mm		nonmetallic filler (1b)	(solution annealed
	UNS N10276					SB574 Gr. N10276
		Soft (EN 1514-1) with		Spiral wound gasket with	condition) or SB575 Gr.
EN				nonmetallic filler (EN	N10276 (solution
		min. Thickness 1.6 mm
				1514-2)	annealed condition)
		Calculations show that the following applies.

Flange Rating Standards	• ANSI:
	316L SST Flanges according to ANSI B16.5 Table 2-2.3.
	Standard: Max. 302 °F/580 psig
	(150 °C/40 Bar).
	HP/HTHP/C: Up to Class 2500.

Alloy C-276 (UNS N10276) flanges according to ANSI B16.5 Table 2-3.8. HP: Class 1500 up to max 200 °C or max 100 °F/5000 psig (38°C/345 bar) and 392 °F/3500 psig (200 °C/243 bar)

HTHP: Class 1500 up to max 400 °C or max 100 °F/5000 psig (38 °C/345 bar) and

752 °F/2940 psig (400 °C/203 bar).
