TSLP
Quality Control
Tubular
Services is
committed to a quality assurance program,
and was one of the first end finishers to
qualify under the A.P.I. Q-1 program.
To ensure that all phases of production are
in compliance with Q-1 program requirements,
various inspection techniques are performed.
A
visual inspection of the upset is made on
every joint to check for wrinkles, underfill
and punch scores. Each upset end is
also hot drifted approximately one foot from
ends to check for heavy wall or gripper squeeze.
On a periodic basis Quality Control Auditors
will verify upset dimensions and perform visual
inspection of fin grinding techniques.
The temperature of heat treated pipes is monitored
by computer sensors and audited during the
shift by Quality Control personnel using a
hand-held pyrometer.
Each
joint of threaded pipe is visually inspected
and given at least one dimensional inspection
using thread gauges. Lead, taper, thread
height, thread length and stand off are checked
in a sequential basis. If deviations
from A.P.I. standards are found, the previous
four joints produced will be checked.
Coupling make-up on every joint is verified
for torque and dimensional specifications.
Full length drift is completed after coupling
make-up.
