4. Grade (plow steel, improved plow steel, or extra improved plow steel).
5. Diameter of rope, in. (mm).
6. Length of rope, ft (m).
7. Type of construction (Warrington, Seale, or Filler Wire).
8. Type of core (fiber, wire, plastic, or fiber and plastic).
Inspection and Rejection
The manufacturer will, on request of the purchaser, conduct tests as called
for in specifications on reasonable notice from the purchaser. During the tests,
the manufacturer will afford opportunity to the purchaser’s representative to
present.
The manufacturer, when delivering wire rope with the API monogram and
grade designation, should warrant that such material complies with the specification.
The wire rope rejected under specifications should not be wound on
reels bearing the API monogram, or sold as API wire rope. When the wire rope
wound on reels bearing the API monogram is rejected, the monogram shall
be removed.
It is recommended that whenever possible, the purchaser, upon receipt, shall
test all new wire rope purchased in accordance with specifications. If a rope
fails to render satisfactory service, it is impractical to retest such used rope. It
is therefore required that the purchaser shall preserve at least one test specimen
of all new rope purchased, length of specimen to be at least 10 ft (3.05 m),
properly identified by reel number, etc. Care must be taken that no damage will
result by storage of specimen.
If the purchaser is not satisfied with the wire rope service, he or she shall
send the properly preserved sample or a sample of the rope from an unused
section to any testing laboratory mutually agreed upon by the purchaser and
the manufacturer, with instructions to make a complete API test, and notify the
manufacturer to have a representative present. If the report indicates compliance
with specifications, the purchaser shall assume cost of testing; otherwise, the
manufacturer shall assume the expense and make satisfactory adjustments not
exceeding full purchase price of the rope. If the report indicates noncompliance
with specifications, the testing laboratory shall forward a copy of the test report
to the manufacturer.
Wire-Rope Sizes and Constructions
Typical sizes and constructions of wire rope for oilfield service are shown in
Table 4-30. Because of the variety of equipment designs, the selection of other
constructions than those shown is justifiable.
In oilfield service, wire rope is often referred to as wire line or cable. For
clarity, these various expressions are incorporated in this recommended practice.
Field Care and Use of Wire Rope
Handling on Reel. When handling wire rope on a reel with a binding or lifting
chain, wooden blocks should always be used between the rope and the chain to
prevent damage to the wire or distortion of the strands in the rope. Bars for
moving the reel should be used against the reel flange, and not against the rope.
The reel should not be rolled over or dropped on any hard, sharp object to
protect the rope, and should not be dropped from a truck or platform to avoid
damage to the rope and the reel.
