Difference between Piping & Pipeline

[Ikhwan Hafiz]

Hello guys,

I need some information to how extend these particular field differ to each other in term of technicality and do they really diverge from each other? Hopefully some of you may advise these discrepancies to me. Thanks in advance.

Pipeline - Long series of Pipes usually of large diameter often underground with few fittings & equipment's mostly Pumps & Valves mainly to control the flow, that are laid with an intention to transport any fluid whether liquid or gas over long distances.

Piping - Large series & networks of Pipes within the well defined boundaries of the plant/plot with all fittings & equipment's like Pump, Valves, Unions & other Miscellaneous items with an intention to transfer fluid from one facility to another within those boundaries as required.

Tubing - Large Series & networks of Tubes with most minimal fittings & Valves without the intentions to regulate the flow, just to transfer processed fluids from one facility to another.

Conduit - These are the pipes whose networks are laid within the boundaries of facility not to transfer any fluid but to protect the electrical and optical fibers & cables from external environment.

Ducting - An often enclosed passage sometimes open also or channel of any shape from cylindrical to cuboidal for conveying any substance from solid to gas from one place to another.


To understand better "All Piping, Tubing, Conduit can be classified under Duct but not vice - versa”

The Few Differences are as follows:-

1. Pipes - They are classified on basis of Nominal Diameter (N.D.).

2. Tube - They are classified on the basis of Outside Diameter (O.D.).

3. Conduit - They are also classifieds on the basis of Nominal Diameter (N.D.).



Piping Terminology;

Transmition pipelines: Usually long, relatively large diameter lines, May Tranport Hydrocarbon fluids and or Gas. from prudocing fields to processing plant or refineries.. From plants and refiniries to marketing centers

Flowline: Two phase lines (Non separted HC with two phase (liquid and gas) flows before entering the inlet separator), connecting welss to production manifolds. range from 2 - 20 inches.

Trunkline: Two or more well flowlines connected to a larger line that carries the combined well stream to the production manifold. range from 10 to 42 inches.

Injection lines: Transport high pressure gas or water to wellheads for injection into the producing formation. Fluids are injected for: Reservoir pressure performance, production enhancements, conservation of gas, Gas Lift, Produced water disposal , waterflood, steam flood.

Piping / Plant (Facility) Piping (on plot) : Piping witihin the well defined boundaries of the processing plants, piping compression station or pumping station. Used for a variety of fluids within those boundaries as required.
