Type 40 & 80 Seamless Carbon Steel A-106
Weld Outlet

Technical Data

Island Type 40 & 80 Weld Outlets are manufactured from material which meets the requirements of ASTM A234. However the fittings are rated in accordance with the procedure for determining area replacement as outlined in the various ANSI codes.

Temperature-Pressure Ratings

Temperature-Pressure rations are based on the area replacement concept outlined in the ANSI Codes. Island Type 40 & 80 Weld Outlets have been subjected to exhaustive burst-pressure testing with the results showing a 5 to 1 safety factor -- that is to say, burst pressures were minimally five time higher than the maximum allowable working pressures indicated in these charts. To allow for corrosion, use the following formula:

P2=(T-C)/T X P1, where:

P1 = Maximum allowable working pressure per the following charts.

P2 = Working pressure with allowance for corrosion.

T = Thickness of Type 40 & 80 Weld Outlets (Chart)

C = Corrosion allowance in inches.

To compute the maximum allowable working pressure for ANSI B31.3, multiply the pressures shown in the charts by the following factors:

Temperature   Multiplicative
Factor
-20 to 400F 1.30
500F 1.26
600F 1.13
700F 1.10
750F .86
800F .72

To compute the maximum allowable working pressure for 45 Degree Type 40 & 80 Weld Outlets, multiply the pressures shown in the charts by .7 for ANSI B31.1 and by .93 for ANSI B31.3.
