2. TEST REQUIREMENTS AND METHODOLOGY DESCRIPTION

2.1.AXIAL IMPACT TEST

The primary function of a thread protector for the pipe ends is to protect the threads and

critical sealing areas from impact. This type of damage may occur at any point during the

transportation and handling process.

The tests must be performed at three

different environmental conditions -46°C,

+21°C and + 66°C (-50ºF, 70ºF, 150ºF),

that potentially could modify the

characteristics of the protectors. For the

tests it has been employed a guillotine that

reproduces the requested energy. The

sample shall be placed in a vertical

position, with the thread and the protector

in the upper part. The impact shall be

done in the middle of the protector.

The protector shall withstand an impact according to the energy value described in the table 2

below:

Table 2. Axial Impact Energy Values

Temperature 0C Minimum impact energy in Joules

≤ 3 ½” >3 ½” to 8 ¾” > 8 ¾”

66 407 1627 2034

21 407 1627 2034

-46 230 814 1085

The impact shall be given with a solid metal

bar 1 ½” (38 mm) wide and a minimum free

fall height of 12” (30 cm);

The impact should be performed at three

different temperatures:

+66⁰C;

+21⁰C;

- 46⁰C;

To ensure that the protectors and its end

size pieces have completely acquired the

temperature (externally but also internally)

the piece must have soaked at the required

temperature for at least 30 minutes.

To be considered as approved, the

connection must not present any damages

after the impact at any of the three test

temperatures, even if the protector is

completely destroyed (Fig.2).

Fig.2 a) NOK b) OK


2.2. ANGULAR IMPACT TEST

For angular impact it has been employed a

flat steel plate.

The sample shall be placed in a 45⁰ angle

position, with the protector in the upper part.

The impact shall be done in the face of the

protector.

The protectors shall withstand an impact

according to the energy value described in the

following table:

Table 3. Angular Impact Values

Temperature 0C Minimum impact energy in Joules

≤ 3 ½” >3 ½” to 8 ¾” > 8 ¾”

+66 203 814 1017

+21 203 814 1017

-46 115 407 542

The impact shall be performed with a flat

steel plate and a minimum free fall height of

12” (30 cm).The impact shall be given a

three different temperatures:

+66⁰C;

+21⁰C;

-46⁰C;

To ensure that the protectors and end size

pieces have completely acquired the

temperature the piece must have soaked at

the required temperature for at least 30

minutes.

To be considered as approved, the

connection must not present any damage

and ovality after the impact at any of the

three test temperatures, even if the protector

is destroyed.


The stripping test is fundamental to evaluate the capacity of a pin protector to remain on

the pipe when an axial force is exerted on the inner edge. This force might be a result of a

relative motion between two adjacent joints during the transportation, or it might occur during

handling when a pipe is dragged along the ground up to the drill floor.

Here the formula applied:

Fax = 60 • w

Where:

Fax – axial force (pounds force);

60 – constant;

w - nominal weight. (pounds/feet)

This test applies only for the pin protector. The objective of this test is to validate the

protector resistance to striping while being pulled away from the connection.

For make a test:

- Apply the storage and/or thread

compound to the connection as required.

- Make up the protector as per

specification. Record the makeup torque.

- Stabilize the test piece sets at -46, +21

and +66⁰C.

- Perform the stripping test according to

IADC/SPE 11396 and the required

temperature and with an axial load equal

or greater than Fax.

- After the test, remove the protector and inspect for torn threads.

- Acceptance criteria is “Protector Thread may show sign of stress but shall not be torn away”.

2.4.HOOKABILITY TEST

For protectors designated as liftable, must be performed test to confirm the suitability of the

protector in lifting applications. Two separate test shall be performed using the same load, but at

different angles to represent different types of rigging set-ups.

For the first test load, the lifting wire shall apply the load in a direction approximately

perpendicular to the axis of the pipe sample.

For the second test load the lifting wire shall apply a load in a direction approximately 20°

from the axis of the pipe. The test load shall be calculated as follows:

L (load, lbs) = 1.5 • 45 (ft) • W (lbs/ft)

Make-up the test pieces at ambient temperature with storage compound using the

recommended force torque from table 4. Apply the load and hold for 5 minutes. Remove the

load and inspect the connection for damage. The type of hook, loads and test set-up shall be

documented.

2.3.STRIPPING TEST


2.5. VIBRATION TEST

During transportation pipes are carried by road on the back of a trailer, thread protectors are

submitted to vibration loading. Under these condition protectors must remain screwed to

continue to provide an optimum protection.


recommended installation torque force form Table 5.

Perform vibration testing as per MIL STD-810. Test shall be conducted at a minimum of

900 RPM (15 hertz) with a minimum of 0.33 inches vertical displacement.

The protector shall not fall off or out during a one-million-cycle test.

After the completion of the test measure and record the breakout torque for the protector.


2.6. TORQUE TEST

The purpose of this test is to determine protector reacts to temperature changes and

excessive make-up torque. Protectors, which are damaged during make-up, will be more

susceptible to loosen or fall off during transportation and handling. Temperature changes can

affect the fit of the protector.

To evaluate the torque stripping resistance of the thread protector during make-up, an

attempt should be made to "strip-out" the pin and box protector.

The required "strip-out" torque must meet or exceed the over-torque limits specified below:

To evaluate the effects of temperature, make-up the sample using storage compound and

manufacturer's recommended practice and torque.

Record the temperature and the torque used for make-up. Stabilize the samples at -50°F, 68°F

and 150°F and breakout the protector recording the torque.


2.7. CORROSION TEST

A protector should be able to prevent water penetration along threaded area in order to

prevent potential corrosive attack of threads and seals.

The cut-off end of the connector shall be sealed and protector vented to allow air flow

circulation.

A salt spray test per ASTM B117 shall be conducted for as minimum of 1000 hours at + 35°C

(95°F).

The test piece shall be oriented in the test chamber to simulate pipe rack storage.

At the completion of the test remove the sample and inspect for corrosion.

Seal surfaces shall have no corrosion damage. Other areas of the connection shall have less

than 10% damage on the external surfaces of pin connections and the internal surfaces of box

connections.

Record the storage compound used and provide photos of any corrosion areas.

2.8.DIMENSIONAL STABILITY TEST

Measure and record the thread diameters on the protector at 21°C (70°F).

Stabilize the samples at -46°C (-50°F), and 66°C (150°F) and immediately measure and

record the thread diameters.

Re-stabilize the samples at 21°C (70°F) measure and record dates again.

Changes in thread diameter resulting in thread engagement of less than one-half of the

specified thread height per side shall be unacceptable throughout the design temperature range.
