This document discusses oil transfer pipes. Pipelines are the most economical method for transferring oil compared to other methods like trucks and rail. The key aspects discussed are pipe materials, dimensions, standards, end preparations, sizes, manufacturing methods, and operating conditions pipes may encounter like pressure, temperature, and corrosion. Factors like material, wall thickness, diameter, length, end type, and manufacturing process are considered when specifying pipe requirements. Pipes transfer fluids and are circular, while tubes can have other shapes.

1. A journey through pipe

2.  The oil can transfer by Truck ,Rail road ,Vessels and
pipe line.
 Pipe is Economically best by compare to all because it
have only one capital cost and less maintenance.

3.  Pipe is a section which transfer the fluids ,slurries and
powders etc..Here we are dealing Oil conveying pipes.
 Pipe, Tube and Hose are same by working, but they are
different.
 The Hose is a flexible pipe for flexible working and
handling.
 The Pipe and Tube may same by the purpose, But the
shape of the pipe must in Circular, it not necessary for
Tubes( square, oval, rectangular etc..)

4.  We are dealing pipe for oil Transferring, so the
materials are, Carbon steel, Stainless steel and Alloy
steels.
 The pipe may be used in following categories
On Shore
Off Shore
Process line
The operation condition is differ in each category. By the
way the material selection is important.

5. Some operating conditions are depicted below,
 High pressure & low Pressure
 High Temperature & Very low Temp
 High corrosiveness
 High strength

6. By quoting the pipe we describe the pipe materials and
dimensions by simple terms for clear and best
understanding.
The basic terms are following
Materials by standard code , Manufacturing
method, End preparation and wall thickness and
diameter etc..

7. Standard:- We widely using ASTM and ASME
standards, but we have to know other standard also.
The ASME std represent the dimension quality and
ASTM say about the material and it manufacturing
method. In additional some case include the Class (CL)
that is describe the Heat Treatment and inspection
methods.
NB:- Nominal Bore that is diameter of the pipe. this
represent the inner dia(ID) of the pipe in inches.
SCH:- This is for Wall thickness, SCH increase the wall
thickness also increase.
STD=40, XS=80, XSS=160 and above

8. End preparation:- The end of the pipe are made different
for it place of applications.
BE-Bevel end, TE- Threaded End ,PE- Plain End
Manufacturing:- The method is note by following
SMLS/SML-Seamless
EFW-Electrical Fusion Welded
ERW-Electrical Resistance Welded
CW- Continues Welded
DSAW-Double submerged Arc Welded

9. Sizes:-
The NB of pipe is 1/8’’ to 80’’
And the length can note by
SRL- Single Random Length: up to 12meter.
DRL- Double Random Length: up to 24 and above.
*The sizes are differ according to the manufacturing method.
