Drilling Line

Drilling Line FEATURES

Steel wire ropes with excellent wear proof and crush resistant performance, good durability and high breaking force, are used as drilling lines. The 6 x 19 classification of wire ropes includes standard 6 strands, round strand ropes with 16 through 26 wires per strand. The 6 x 36 classification of wire ropes includes standard 6 strands, round strand ropes with 27 through 49 wires per strand. All the steel wire ropes conform to API 9A and API Monogram can be used.

Nomenclature example when specifying a rope:

1" x 5000' 6 x 19 S PFR RRL IPS IWRC

1" = Diameter of Line
5000' = Length of Line
6 = Number of Strands per Line
19 = Number of Wires per Strand
S = Seale Pattern; Seale All layers contain the same number of wires.
PRF = Preformed Strands are helically formed into the final shape.
RRL = Right Regular Lay
IPS = Improved Plow Steel with breaking strength between 1770 and1960 MPa.
IWRC = Independent Wire Rope Core
