You will learn about fundamental of pipes that used in process piping of oil and gas industries. You will learn different types of pipe and common material and ASTM grades. You will also learn about NPS & Schedule number that used to define pipe size and thickness. You will also learn about double random & single random pipe length, and what is the difference between small bore and large bore pipe.

piping system to
transport liquid,
gas and sometimes
solids.

9. Pipe Dimension - Size
Pipe Dimensions are covered in following Standard
ASME B36.10 – Welded and Seamless Wrought Steel
Pipe (Carbon & Alloy Steel)
ASME B36.19 – Stainless Steel Pipe
Three different terms are commonly used to define
the size of the pipe.
NPS
 NB
 DN

11. Pipe Size
B36.10 cover standard dimension of pipe in the
range of 1/8” to 80”
B36.19 cover standard dimension of pipe in the
range of 1/8” to 30”

12. Pipe length
Single random
4.8 m to 6.7 m with 5% of lengths 3.7 to 4.8 m
Double random
minimum average of 10.7 m and a minimum
length of 4.8 m with 5 % 4.8 m to 10.7 m
Fixed length as per purchase order

13. Pipe Thickness
Thickness are expressed in Schedule number (5,
10, 20, 30, 40, 60, 80, 100, 120, 140, 160)
Also in STD, extra strong-XS, double extra
strong-XXS
Higher the schedule higher the thickness

14. Pipe Thickness
What is Schedule No?
A schedule number is an approximate value of
the equation = 1000 P/S
P is the service pressure in (psi)
S is the allowable stress in (psi)

15. Pipe Thickness
The outside diameter of each pipe size is
standardized. Therefore, inside diameter
depends on the schedule number of pipe
ASME B36.10 provides standard dimension
requirements for Welded & Seamless wrought
iron pipes.

16. Pipe Thickness for Stainless Steel
Thickness is expressed in Schedule number (5S,
10S, 40S, 80S)
Schedule no with S suffix is as per ASME B36.19
and primarily intended to use with stainless
steel pipe. ?sub_confirmation=1

17. Pipe ends
Plain end
Beveled end
Threaded end
Special end such as
socket and spigot with
O-ring etc.
