Abstract
Sacrificial anode cathodic protection is one of the most widely used methods in protecting buried oil pipe lines against the corrosion damages.
The Chemical analysis of prepared alloys was carried out using (dissolution spectrometer) in Specialized Institute for Engineering Industries (ISEI) as shown in Table (1). 2.2 Samples Preparation: 2.2.1 Samples Used in Tafel Test: 1.
This test is carried out in Babylon University, Civil Engineering College, and Soil & Sanitary Laboratories.

efficiency, timely, relevant government agencies to keep step with development of emergency and post disaster reconstruction work.
3.1.2London
The public meeting in London adopted the “Emergency Response Plan of London” in 2011[4], the main content of which involved:
General provisions
It introduces the definition, the goal, schedule of emergency response as well as the review and revision of plan in this section.
2) Statement/Termination of emergency
3) The notice and start
4) The community control group (CCG)
It mainly introduces the composition of CCG and membership in this part.
5) The responsibility of each member of the CCG
The members of the CCG includes mayor, Police Commissioner, Fire chief, the medical health officer and Department of Transportation, etc, and the responsibility of each member was clearly described in this section.
6) The responsibility of members of the CCG advisory board
The members of the CCG advisory board include director of human resources, city engineer
Risk analysis is the basis of the emergency plans, whose result not only help determine the key of emergency work, but also provide the necessary information and materials for emergency preparedness and response.

TPIF requires the realization of a complete or partial die, which can be made of materials easily workable on the same CNC machine used for ISF, like: resin, wood, aluminum.
This can be explained considering that closer passes, in other words lower ∆θ, affect a lower material volume and give rise to a more gradual deformation increment, improving the material ability in deforming without rupture.
Next studies will be oriented on testing different sheet materials and the differences between positive and negative die incremental forming processes.
