Critical Plant Equipment and Piping: A designation imposed on equipment or piping system that will entail extra design requirements with the objective to minimize business interruption.
Cross-Country Pipeline: The pipeline and its appurtenances used to transport fluids across the country or offshore between isolated plant areas or camps.
Design Agency: The agency responsible for designing the piping system. It could be the design Contractor, the Lump Sum Turn Key Contractor or in house design organization.
Design Conditions: All conditions (such as pressure, temperature, ambient conditions, service, etc.) that govern all or part of the design and selection of piping components.
Design Factor: It is numerical multiplier used to calculate the allowable stresses for transportation piping systems. This factor is used by ASME B31.4 and ASME B31.8 Codes.
Flowlines: Pipelines connected to oil, gas or water wells for production, injection or well testing.
Hazardous Service: Any fluid service other than Category D as defined in ASME B31.3.
Maximum Allowable Operating Pressure (MAOP):
This term refers to the maximum pressure at which a piping system can be operated within the provisions of the applicable ASME B31.4 and or B31.8 codes.
It is the maximum internal pressure permitted in the piping system for continued operation at the most severe condition of coincident internal or external pressure and temperature (minimum or maximum)
Normal Operating Conditions: The expected conditions (such as pressure, flow, temperature, ambient conditions, service, etc.) to occur during normal operation per design.
Off-Plot: Off-plot refers to any area outside of the plot limits. Off-plot can include plant areas such as roads, pipeways and open lots between plant units.
On-Plot: On-plot refers to any area inside the plot limit. On-plot piping is generally, but not necessarily, designed to ASME B31.3 code except in area(s) set aside for piping within other code or government regulations.
Perimeter-Fence: The fence which completely surrounds an area designated for a distinct function (plant or camp).
Plant-Area: The designated area engaged in the production, processing, storage and transportation of crude oil, gas, refined products and their derivatives.
It could be inside an onshore perimeter fence, or on the decks of offshore structures.
Plant Piping: Pressure piping system, within an identified plant-area.
Plant Utility Service: The supply of steam, water, air, nitrogen or inert gas within a processing plant.
Plot Limit: The plot limit is a boundary, within the plant area, which surrounds a single plant or function.
The plot limit may be physical such as a fence (not necessarily an SSD fence), a wall, the edge of a road or pipe-way, chains and posts or a boundary indicated on an approved plot plan.
Production Pipelines: Those pipelines engaged in transporting crude oil or gas from the producing wells to the designated facility for processing. These include flowlines, testlines, trunklines and transmission lines.
Process Piping: Pressure piping which is designed in accordance with ASME B31.3. This piping is typically found in petroleum refineries, chemical plants, cryogenic plants, and related processing plants and terminals.

Testlines: Flowlines that are used for testing an individual producing well without affecting the operation of the trunklines.
Transportation Piping: Pressure piping system that is designed in accordance to ASME B31.4 or/and 31.8.
Typically, these pipelines transport hydrocarbon fluids or others between processing plants or storage facilities to export terminals and end users.
Trunklines: Pipelines to which two or more flowlines are connected.
Well Head Piping: The piping system connecting the wellhead to the flowline first isolation valve.

30, What do you means by Series A and Series B Flanges?
There are two series of flange dimensions. Series A specifies flange dimensions for general use flanges. Series B specifies flange dimensions for compact flanges which, in general, have smaller bolt circle diameters than Series A flanges. These two series of flanges are not interchangeable. The user should recognize that some flanged valves, equipment bolted between flanges, and flanged equipment may only be compatible with bolt circle diameter of one series off Langes.
31. How to check the dimensions of the flanges?
OD of Flange, Thickness of Flange, Length through hub, Dia of Hub, Raised Face Dia, Dia of Bolt Circle, Dia of Bolt hole, Fillet Radius.

Slip on: The Slip-on type flanges are attached by welding inside as well as outside. These flanges are of forged construction.
Socket Weld: The Socket Weld flanges are welded on one side only. These are used for small bore lines only.
Screwed: The Screwed-on flanges are used on pipe lines where welding cannot be carried out.
Lap Joint: The Lap Joint flanges are used with stub ends. The stub ends are welded with pipes & flanges are kept loose over the same.
Welding Neck: The Welding neck flanges are attached by butt welding to the pipe. These are used mainly for critical services where the weld joints need radiographic inspection.
Blind: The Blind flanges are used to close the ends which need to be reopened.
Reducing: The reducing flanges are used to connect between larger and smaller sizes without using a reducer. In case of reducing flanges, the thickness of flange should be that of the higher diameter.
Integral: Integral flanges are those, which are cast along with the piping component or equipment.
