Product Description

Manufacturer of Factory of spiral welded steel pipe/SSAW Pipe

1. OD: 219-3500mm
2. WT: 4-25mm
3. Thread: LTC STC BTC
Visual Examination of Coating

1. Pipe would be free of ovality through out the length of pipe
2. Pipe inside and outside surface should not have fold, hairline, delamination, crack, rolling
Defects such as folding, scarring. These defects shall be completely removed, remove depth
Shall not exceed 12.5% of the nominal wall thickness.
3. Coupling outside surface should not have fold, hairline, delamination, crack, rolling defects
Such as folding, scarring.
4. Casing pipe and coupling thread surface should be smooth, there should be no burr, tear
And something to make the thread tied to interrupt impact strength and other defects

Inspection of Physical Properties

Hydrostatic pressure test, flattening test, sulfide stress corrosion cracking test, hardness
Testing, Tensile test, transverse impact test, Determination of grain size

Application and Category

Oil casing is to maintain the lifeblood of any oil Wells. Due to the different geological
Conditions, downhole complex stress state, tension, pressure, bending, torsion stress
Combination on the pipe body, which raised higher requirement about the quality of the
Casing itself. Once the casing damage itself for some reason, that may lead to the reduction
Output of the well, or even scrapped.

ApplicationUsed in o il well drilling. It is m ainly used for drilling process and after
Completion of borehole wall support, to ensure that the drilling process
And the whole Wells after completion are normal running.
