Abstract : In this research we will e xplain the usage of Pipelines in our life and some problems that may happens to it and how to overcome this , we will also explain the different welding techniques and how to select the best for the needed situation . Also we will review the welding defects and how to remedies it , the defects that happens to high pressure and temperature pipelines (with actual example of el kuriemat power station and the boiler pipe problems )  , also the welding procedures , joints types , the new numerical method to avoid this welding problems   List of Contents 1.      Introduction  1.2.          Metal Pipes  1.3.          Piping  1.4.          Pipe size  1.5.          Pipe wall Thickness  2.      Classification of Pressure Piping  2.2.          Pressure Tubing 2.3.          El kuriemat electric power plant capacities 3.      Weld heat tented area induced failure of boiler water wall tubes in power generation plant 3.1.    

Top Three Common Problems for Car Engine  Once morning your engine doesn't start... What's wrong? if you know how engine works, you can understand the basic things that keep an engine from working. their is Three fundamentals reasons for that problem : lack of compression , a bad fuel mixor or lack of spark. Beyond that, thousands of minor reasons that can create problems, but these are the "mostly happens reasons" , here is a quick rundown on how these problems Lack of compression - If the charge of air and fuel cannot be compressed properly, the combustion process will not work like it should. Lack of compression might occur for these reasons: - Your piston rings are worn (allowing air/fuel to leak past the piston during compression). There is a hole in the cylinder. - The intake or exhaust valves are not sealing properly, again allowing a leak during compression - The most common "hole" in a cylinder occurs where the top of the cylinder (h

Trick Photography and Special Effects  by Evan Sharboneau is a popular Educational eBook that shows how to do make the photos trick that often capture attention and from viewers. It is detailed and includes explanations of many complicated techniques that are fun to learn. I found this eBook is very useful and original. This eBook  is inspiring with new ideas and techniques. It is three well-organized modules. Each module contains chapters and sub-chapters in order to make the vast amount of information more easily digestible. The list of the content is really just scratching the surface because each section has many sub-chapters focusing on various techniques for specific effects: LONG EXPOSURE EFFECTS & LIGHT PAINTING ( 80 PAGES ) -  Fundamental of Lights and Techniques -  Other Sources of the light -  Light Painting Techniques -  Lightning -  Motion Blur -  Star Trails -  Other Fun Long Exposures TRICK PHOTOGRAPHY AND SPECIAL EFFECTS ( 60 PAGES ) -  In-Ca
