Chop saws online.The trowel method is a hand-applied application generally used for thin lining (i.e. ladle tops at the pour areas). The amount of water will vary with the type of refractory and must be just enough for the material to be sticky and stay in place. An important thing to pay attention to when troweling is to avoid over troweling the finished surface. This will bring cement to the surface and have the effect of sealing the refractory, thus restricting the escape of water vapor, which occurs during dry out. Sealed-in moisture can turn to steam during dry out and explode the lining. For utilization and geographic location, ODS-Petrodata''s November Offshore Rig Locator shows 264 jackups working, out of a total worldwide fleet of 388 rigs, for 68% utilization, down from 82% one year ago. This is principally due to sharp cuts in the U.S. Gulf of Mexico, where only 72 of 150 available units were working due to lower oil/gas prices. The second most active area was the Persian Gulf, with 46 of its 56 rigs working. The North Sea/NW Europe had all but one of its 34 jackups working. Asia accounted for 60 rigs--in India, 16 of 20 units were working; SE Asia had 19 of its 22 rigs active; and the Far East saw 11 of its 18 jackups working. West Africa was working 19 of its 23 rigs. Other active areas included: the Mediterranean/Black Sea, 10 of 12; Red Sea/Gulf of Suez, 11 of 11; and South/Central America, 18 of 25. The antennae need to be appropriately positioned to complete the triangulation, and the best readings aren''t from where fire engines typically are parked at the scene.System evaluation is expected to continue to the next phase. Although high-rise capability adds a significant level of complexity, Orange County has nailed many of the X - Y single-story issues to make the system useful for fires at strip malls, as well as most homes and standalone stores."We''ve done the actual hands-on stuff, now we need to do the data analysis and make some decisions," says Godfrey. "If we feel like this is worth pursuing, features such as high-rise operation and antenna placement are issues on the agenda to deal with." ©2003 www.circular-saws.net All rights reserved. |
