ETCM 4330- Assignment 4 The P-Line Construction Company will be constructing a 6 inch welded steel pipeline in west Texas. The contractor will be using a hydraulic pipe bender with 6 inch clamping jaws. The pipe has an allowable maximum bend of 2.5 degrees. The pipe joint length is 40 feet. The radius of all bends is 50 feet. 1. Compute the change in slope at station 1+40. 2. What is the change in elevation from station 0+00 to Station 1+40? 24 3. What is the pipe length from station 0+00 to station 1+407 142Mo 4. Compute the change in slope at station 2+40 s. what is the change in elevation from station 140 to Station 2+407-1·74 6. What is the pipe length from station 1+00 to station 2+40? I 7. Compute the change in slope at station 4+00. 8. Compute the pipe bend angle needed at station 1+40 9. Compute the pipe bend angle needed at station 4+00. 10. How many linear feet of pipe will be used from station 0+00 to station 4+50 4 ft +

Solution

1. change in slope = s2 - s1 = -1 - 10 = -11⁰ 00\'

4. change in slope = -15 - (-1) = -14⁰ 00\'

7. change in slope = 0 - (-18) =18⁰ 00\'

8. bend in pipe is 6⁰

9. bend in pipe is 8⁰
