1. A standpipe was crucial for smooth circulation.

2. In the throttle control box available , standpipe pressure is controlled by hand with lower accurate, by which underbalanced well drilling is hard to be performed .

3. There are no shower facilities and the standpipe taps lack bowls, so water tends to leak into the ground and under people's homes.

4. Construction technology of prefabrication combination standpipe, which is used firstly in China, has some characteristics of simple construction, reliable quality and high fabricated precision.

5. Sometimes there was only one standpipe to provide the entire lane or court with water.

6. Standard for the Installation of Standpipe, Private Hydrants(http:///standpipe.html), and Hose Systems.

7. The negative pressure gradient and slip velocity in standpipe increase with the increase of circulating rate.

8. Welding-seam on the standpipe.

9. The end gate of the upper conduit, also showing the winding house and cabin housing one of the hydraulic standpipes.

10. Through this high pressure line, mud is pumped in to the standpipe and drill pipe.

11. Based on the experimental results and analysis, the idea and principle about design of standpipe shape and dense-phase transportation of catalyst in the standpipe were presented.

12. The results show that the size and direction of the gas-phase velocity in the standpipe are chiefly affected by the mass flux of solid and negative pressure gradient.

13. Where greater coverage is required, multiple gauge glasses using either independent vessel connections or a standpipe shall be used.

14. The total pressure drop in hung-up regime is approximately equal to that in the standpipe.

15. The influence of the arrangements of pipes on gas solid flow characteristics in the dense section of standpipe in the circulating fluidized bed is studied on a cold state experiment platform.

16. In this paper, the authors summarize the fabrication and installation technology of prefabrication combination standpipe to form a series of construction technologies.

17. The effect of the aeration to the pyrolysis chamber on the pressure distribution of the standpipe was more remarkable than on the riser.

18. In order to prevent drill fluid splash during drilling tool connection, condensed air is injected into standpipe to drive drilling fluid down.

19. The utility model discloses a three-jaw quick joint automatic opening and closing ball valve used for connecting a sprinkling standpipe and a sprinkler.

20. A teenager braves the flies and stench of a leaking outdoor toilet to draw water from a standpipe.

21. The utility model relates to a combined starlike multi-purpose support seat, comprising a standpipe, a foot rack, an adjusting screw, a pipe clip, clipping sheets and a jack seat.
