Casing and Casing String Design

of the pipe from damage under normal handling and transportation. External

thread protectors shall cover the full length of the thread on the pipe and inter-

nal thread protectors shall cover the equivalent total pipe thread length of internal

thread. Thread protectors shall exclude water and dirt from the thread during

transportation and normal storage period. Normal storage period shall be

considered as approximately 1 year. The thread forms in protectors shall be such

that the product threads are not damaged by the protectors.

Material.

Protector material shall contain no compounds capable of causing

corrosion or promoting adherence of the protectors of the threads and shall

be suitable for service temperature (-50 to +150°F)

(-46

to

+66OC).

Pertormance Properties.

Results of years of field experience have revealed that

to reduce the risk of failure, the minimum yield strength should be used instead

of average yield strength to determine the performance properties of casing.

Values for collapse resistance, internal yield pressure, pipe body, and joint

strength for steel grades as in Table 4141 are given in Table 4-150. Table 4-150 is

directly taken from

API

Bulletin 5C2, 17th Edition, 1980. Formulas and pro-

cedures for calculating the values in Table 4-150 are given in Bulletin 5C3 [152]

and are as follows:

Collapse Pressure (Section

1

of

API 5C3)

Yield Strength Collapse Pressure Formula.

The yield strength collapse

pressure is not a true collapse pressure but rather the external pressure p,, that

generates minimum yield stress

Y,

on the inside wall of a tube as calculated by

(4-308)

The applicable D/t ratios for yield strength collapse are shown in Table 4-151.

Plastic Collapse Pressure Formula.

The minimum collapse pressure for the

plastic range of collapse is calculated by

(4-309)

The formula for minimum plastic collapse pressure is applicable for D/t values

as shown in Table 4-151. The factors

A,

B, and C are given in Table 4-152.

Transition Collapse Pressure Formula.

The minimum collapse pressure for

the plastic

to

elastic transition zone

P,

is

calculated by

(4-3 10)

The factors

F

and

G

and applicable D/t range for the transition collapse

pressure formula are shown in Tables

4-152

and

4-151,

respectively.

Elastic Collapse Pressure Formula.

The minimum collapse pressure of the

elastic range of collapse is calculated by

(4-31

1)

Collapse Pressure under Axial Tension Stress.

The reduced minimum

collapse pressure caused by the action of axial tension stress is calculated by

pa

=

p,,[,/1-0.75[(SA+Pi)/Yp]2

-0.5(SA+Pi/Yp)]

(4-3 12)

Equation

4-312

is

not applicable if

P,,

is calculated from the elastic collapse

formula.
