Pipe Stress.
pipe carry's alot of things.stress comes into mind at pump connections and steam hangers and the system of steam relies strongly on proper stress points to expand.this is called a steam loop.lets the pipe expand and retract without affecting what it is connected to .stress through out the system can be seen at times even heard
For calculating the collapse pressure of a pipe, you first need to calculate the Hoop stress, which is given by :- Stress = Circumferencial Force/(radial thickness*axial length) If the stress crosses this value the pipe would collapse.
A. A 2-in schedule 40 sheets pipe is used as a leg for a machine. The Load carried by the leg is 2350lb. a. Compute the bearing stress on the floor if the pipe is left open at its end b. Compute the bearing stress on the floor if a flat plate is welded to the bottom of the pipe having a diameter of the pipe
You can calculate the combined effect of bending and torsional stress on a rotating pipe using the outside diameter. The angle of rotation and the shearing stress should also be considered.
The main water stress in Egypt comes from a combination of the shrinkage of the Nile, the faulty pipe system, and the growing population.
To stress the fact that a picture is different from its subject.
i want IS codes 13382:1992 and 9523:2000
It's a standard to decrease the cost of fabrication. you can choose the better sch for your uses, depend of : _ the pressure inside the pipe _ life time and corrosion _ mechanical stress _ ...
Temperature
Cast Iron
Class is the classification criteria employ by the manaufacturer to differentiate pipe based on diameter, rating and other criteria. Class 4 just like other classes of pvc pipe can be used for whatever you wish to use it for depending on the location of the pipe and pressure the pipe is subjected to minding the hoop stress equation relations (sigma=Pr/t). Then you can determine which schedule of pipe you actually need.
area = pi x (502 - 302)/4 = 1256.64 mm2 stress = 80N / 1256.64mm2 = 0.06366 N/mm2
Creep usually occurs as a result of thermal and physical stress overcoming the elasticity of the metal preventing it from returning to its original shape after the stress is removed.
