The meaning of “FIG”has been lost in the depths of time but is probably an abbre-viation of figure - meaning drawing, and 1502 is a code forthe working pressure rating - “15” referring to 15,000 psi.But over time the addition of larger diameter pipework andH 2 S pipework has led to the designation becoming corrupted- so beware.   Female UnionMale UnionWing Nut  2   ABC Guide to Temporary PipeworkDrilling and Well Services Ver. 2.0 The meaning of Temporary Temporary, in the context of pipework and flowline equip-ment, applies to any pipework and flowline equipment whichcan be installed or changed-out without recourse to structur-al and process engineering.
