ASTM A403 WP304/L WP316/L WP310S WP321 MSS SP-97 Sockolet
A Sockolet allows for a 90-degree branch connection and with a branch pipe connected to the run pipe via a socket welding connection. It is similar in function to a reducing tee but has a smaller branch connection that is in the form of a socket rather than a tee. They are made of materials such as carbon steel, stainless steel, or brass and are designed to withstand the pressure and temperature of the fluids being carried through the pipes. Sockolets are available in two sizes: “size on size” and “reducing in size.” Fillet welding is used to connect the branch pipe and the Sockolet branch side.

Note:
Where a ellipsis(﹍)appears in the table, there is no requirement and the element need to be analyzed for or reported
The method of analysis for nitrogen shall be a matter of agreement between the purchaser and manufacturer
Columbium 0.10-0.30%; Vanadium 0.10-0.30%.
For small diameter or thin walls, or both, where many drawing passes are required, a carbon maximum of 0.04% is necessary in grades TP304L and TP316L. Small outside diameter tubes are defined as those less than 0.500in.(23.7mm) in outside diameter and light wall tubes as those less than 0.049in.(1.24mm) in average wall thickness
