6.0 Procedure:
6.1
General Requirements
6.1.1
All tube and bar stock shall be produced from ASTM grade TP316L raw material unless
specified in the purchase order. Tubing sized smaller than 3" shall be seamless and larger
than 3" may be welded.
6.1.2
Stainless steel tubing shall be bright annealed at the producing mill in a dry hydrogen
atmosphere (dewpoint <-40°C) or vacuum annealed (10 micron Hg) to a Rockwell Rb 90
maximum hardness.
6.1.3
The sulfur content of fittings and tubing shall be in the range of 0.005-0.017 percent; type
316L VAR and VIM\VAR a maximum of 0.005%. VAR or VIM/VAR will be specified in the
purchase order. This range is an actual range and does not allow for rounding of numbers
as set forth in ASTM A269.
6.1.4
Tubing shall conform to the requirements of ASTM A269 for sizes one-half inch diameter
and larger and ASTM A632 for sizes smaller than one-half inch, except where specified

6.1.5
Bar stock shall conform to the requirements of ASTM A479, except where specified
differently within this specification.
6.2
Dimensional Tolerance Requirements:
6.2.1
End connections on tubing and fittings shall be faced and squared to plus or minus one-
half degree for sizes 1/4" through 3/4" inclusive. Squareness of 1" and larger shall be
+.006". All ends shall be fully prepped and suitable for installation with automatic orbital
welding equipment.
