1 Stir in food coloring if desired. 2  Cook and stir 3 minutes until thick. 3  Remove from heat and transfer to bowl, cool 10-15 minutes.  If strawberries are not smooth, you can either put them through a sieve and smash them or use the food processor.
Nominal pipe size (NPS) is a dimensionless designator of pipe size. It indicates standard pipe size when followed by the specific size designation number without an inch symbol. For example, NPS 6 indicates a pipe whose outside diameter is 168.3 mm.
Re: Mill Tolerance. Mill tolerance is the deviation allowed to a pipe manufacturer from the actual nominal thickness of a pipe. 1) This has been considered by relevant pipes ASTM standards, ASME B31 codes, and ASME B36.10 due to incapability of any mill to produce a pipe with an exact nominal thickness defined. The value in all the mentioned standards has been set to 12.5% of nominal thickness. 2) Both positive or negative mill tolerances can exist in a pipe. Positive would not be causing any significant impact but negative may put you in an odd situation if you didn't consider mill tolerance during piping thickness calculation.
