One recent offlist comment I've had is "why do some people submit not enough specific information" about what they are inquiring about.
Your question is likely easily covered by standards, unless you are doing molecular-level research. In which case, this is not the place to ask questions.
On the other hand, students often post theoretical questions here for "homework help".
Do you know what the coefficient of expansion is for your piping and vessel? Will it grow (or shrink) depending on the temperature differential? Is the piping material different from the vessel? Where is the installation? If it is northern, but not arctic, you will have to accomodate ambient temperatures that range from freezing to hot and humid. Have you looked at this possibility? What is your process fluid(s)?
