The standard 6×7 rope construction material are fiber core and right regular lay.
Commonly use in oil, gas and water drilling industries, the 6 x7 wire rope is also known as a sand line.
It’s typically operated and stored on a winch drum and is capable of tensile forces higher than electric wire line or slick line.
A fiber core (generally made of vegetable such as sisal, etc., or a synthetic like polypropylene, etc.) gives this steel rope cable excellent resistance to fatigue caused from excessive bending.
Spools evenly and resists kinking. Common uses: coring lines, sand lines, trawl cables, swabbing lines.
