CORROSION INHIBITOR SKID WELLHEAD PLATFORM

A general term for injection processes that use special chemical solutions to improve oil recovery, remove formation damage, clean blocked perforations or formation layers, reduce or inhibit corrosion, upgrade crude oil, or address crude oil flow-assurance issues. Injection can be administered continuously, in batches, in injection wells, or at times in production wells.

SAMPLE ASSEMBLING WITH FITTING TRAYS

Adding and editing components becomes easier in AutoCAD with tool palettes. The tool palettes contain blocks. With the parameter action Polar Stretch, you can just type the length you desire and AutoCAD will stretch the tray to that length. Furthermore, you can rotate the block before you place it. In my opinion the tool palettes are user friendly. Even a novice can use them. Moreover you can insert blocks into your drawing with drag and drop. It is easy to access from tool palettes.

Open and close the tool palette by pressing CTRL+3. You can auto-hide the tool palette in the vertical blue area of the tool palette, simply click on the symbol <>I. By doing that, you leave more space in the drawing area.
