Question

You are the supervising engineer in the construction of an offshore oil drilling platform that is fabricated by welding stainless steel pipes in a climate in which the ambient temperature is 86 F. Quality control tests indicate that the weld is brittle, and hence, deemed defective. What is the problem in your professional opinion

Answer 1

Answer: this is to render a heat solution of about 1070 degree Celsius with water to quench, so as to retain the carbides solution in the defective steel for re use.

Explanation:

With the climate condition in the off shore oil drilling platform, it won't rake long for the fabricated steels to collapse and cause the loses of multiple lives and properties.

As an expert I will suggest we deconstruct the steels and use Austenitic stainless steel, because of its corrosion resistance.

We might as well sensitised the steels before use. Because the sensitisation occurs in the region that has seen temperature close to 600 and 900°C.

My possible solution to overcome this defect stated by the quality control and as a result spend less, is that we undergo a HEAT SOLUTION TREATMENT at a 1070°C followed by a water quench to help retain the carbides solution on a rapid cooling in those defective still, and also make it resistance to the climate condition of the area and also commence the project.
