What is max depth that can be safely reached for drilling

Reference no: EM13316944

Steel pipe employed for oil drilling operations is made up of many segments joined sequentially and suspended in an oil well. Suppose the pipe used in one such application has an outer diameter of 7.5cm and an inner diameter of 5cm, a density of 7.90Mg/m 3 , and a yield strength of 900MPa. If the pipe is designed with a safety factor of two [i.e. the maximum stress in the field must be less than half the rated yield stress], what is the maximum depth that can be safely reached for drilling. Where does the maximum elastic strain occur in the pipe?
