Question

What type of pipes should be used to avoid damage by thermal expansion
​

Answer 1

Answer:

again I will say you are weak in history as at that time India has won almost half of Pakistan and you guys were not even able to defend and I think you are right it was foolishness of our political leaders of that time who went for help

otherwise today whole of Pakistan would be a part of India

just to remind at that time we had won pakistan upto lahor

only a few parts of Pakistan were left

and you guys were able to just occupy full jammu and kashmir

and due to that foolishness of our leaders we were forced to leave your teritory

and you guys at that time cheat Indians and just free half of Jammu and Kashmir

so the half of our jammu is with you guys

and Pakistan claimed that to be a part of his territory

but still it's a part of Indian teritory at international level

only you guys are having illegal control over that area

we call that area as POK ( pak occupied Kashmir )

btw if you are from Pakistan you will definately be a Muslim so eid mubarak ❤️❤️

have a nice day ahead and don't have such misunderstandings that India is weak ☺️

Answer 2

Answer:

Straight pipes and 90° elbows are used to avoid damage by thermal expansion.

Explanation:

Thermal Expansion is a process in which the metal expands as the heat is provided.

There are four deflection mechanisms for Expansion Loops, Expansion Offsets, Changes of Direction, and Expansion Joints so that expansion or contraction does not occur.  Expansion loops should be constructed with straight pipe and 90° elbows, in which they are cemented together. The natural movement of the pipe should be restricted in the direction of expansion and contraction.

Hence, Straight pipes and 90° elbows are used to avoid damage by thermal expansion.
