Slightly higher velocity is possible at lower temperatures. In these tables, single numbers represent the industrial safe values for water, steam, air or gas. In the shorter insertion lengths, consideration is given to the velocity pressure effect of water flowing at higher velocities. In these cases, the values in parentheses represent safe values for water flow, and the unbracketed values may be used for steam, air, gas and similar density fluids. 1-1/2-385 WELDIN 4-1/2 220 (170) 233.5 (231) 233.5 (231) 237 (235) 237 (235) 269 (159) 285 (220) 285 (220) 290 (224) 290 (224) MAXIMUM FLUID VELOCITY ­ feet per second* Insertion Length - U 7-1/2 10-1/2 13-1/2 16-1/2 79.4 40.5 24.5 16.4 84.0 42.8 25.9 17.3 84.0 42.8 25.9 17.3 85.5 43.0 26.4 17.6 85.5 43.0 26.4 17.6 96.9 49.0 29.9 20.0 102 52.0 31.6 21.2 102 52.0 31.6 21.2 104 53.2 32.0 21.5 104 53.2 32.0 21.5 19-1/2 11.7 12.4 12.4 12.6 12.6 14.0 15.0 15.0 15.4 15.4 22-1/2 8.8 9.3 9.3 9.5 9.5 10.7 11.4 11.4 11.6 11.6 70° 5950 7800 7800 7350 7224 5200 7000 7000 6562 6450 200° 5750 7050 7800 7350 7224 5000 6200 7000 6562 6450 PRESSURE - TEMPERATURE RATING Temperature - °F 400° 600° 800° 5450 5250 4000 6400 6150 6000 7250 7100 6950 7350 7350 7350 7224 7224 7098 4800 4600 3500 5600 5400 5200 6400 6200 6100 6562 6562 6562 6450 6450 6337 * Maximum velocity rating is based on operating temperatures of 1000° F for wells made of carbon steel, 304SST and 316SST; 350° F for wells made of brass; and 900° F for wells made of Monel.
