The design of piping systems shall take into account the different conditions expected during operation: steam out, start-up, shut-down, cold branch in the case of spare pump, tracing. Piping flexibility shall be provided by change of direction in the piping using bends, loops or offsets. Vertical loops shall be avoided.

Dear
Most of what you mentioned seems 'fine' then what's your query!

Qalander's point is well taken. The title of a thread is to label the thread with a logical identity as to the topic of the thread, not to express your query. The body of the text within the thread is what is reserved for detailing out the various explanations and / or details of the query.

We all know what an offset is. We will answer any questions that are structured and presented within the body of the thread. I personally will not address any question that is inserted in the title of a thread. The title space is simply not enough space to fully express all the required, normal details that are related to an engineering query. If that were the case, I would answer the query in the same amount of words that were used to express the query in the title -- but that would not be constructive, nor a complete answer.

Kindly organize and state the full content of your query in another post so that we can clearly identify exactly what is the query you have.

Thank you.

Thank you for your advice.
What confused me is offsets here is a kind of pipe fittings or other device? I would appreciate if someone kindly give me some explanations or related pictures about offsets.

[Art Montemayor]

Normally, the term “offset” in English or American piping descriptions is used to describe a piping configuration that incorporates a change in direction (whether up, down, or sideways). This change in piping direction is frequently used to allow the piping run to avoid obstructions, equipment, other pipes, or, in well engineered designs, to allow for strategic pipe expansion without causing excessive stress on the installation. An offset in piping is an inherent characteristic that allows the pipe to “flex” and slightly distort with a change in temperature (which causes expansion) and imposed stress due to the expansion growth of the pipe.

I hope this helps you out.

I hope this helps you out.

Thank you again for your warm-hearted help.

So,basically the offset is the configuration, am i correct ?If i use a manifold as an anticipation of a future connection, it is also an "offset"? because it's an expansion (in the future). thank you

Skyline,Hello/Good Afternoon,

Here I feel like disagreeing from your inference as follows;

An 'offset' in a pipeline physical layout is field-fitness requirements fulfillment segment;in order to ensure

1)Safe/adequate alignment

2)Safe and appropriate Cross-overs of any Pipelines from one above/below another

3) Arrangements for helping security and/or Safe supporting and resting arrangements.

Most of these are the items not initially envisage able exactly

Hope this helps in some way about explanation.
