What is Slickline?
Shaped Wire, also known as Profile Wire, is precision-formed wire manufactured into non-round cross-sectional shapes such as flat, square, rectangular, trapezoidal, and custom geometries. Unlike standard round wire, shaped wire is engineered to deliver specific mechanical performance, fit, and functionality within a final component. Central Wire produces high-precision shaped wire designed for tight dimensional control and consistent performance across the entire cross-section.
Built for Downhole Operations in Harsh Environments
Central Wire Slicklines are used in well intervention and maintenance operations, including well measurement, tool deployment, and electro-mechanical applications. With lengths available up to 40,000 feet, these wirelines are designed to perform in sour and sweet wells, where hydrogen sulfide, pressure, and temperature fluctuations can significantly impact material performance.
Critical Alloys for Sour & Sweet Service Conditions
Our GD™ and SUPA® Slicklines are manufactured using a wide range of stainless steel, duplex, and nickel alloys, including:
- 316 Stainless Steel (GD316)
- Duplex & Super Duplex Alloys (GD22, GD100)
- Nickel Alloys (825, GD31Mo, GD35Mo, GD39Mo)
- High-performance proprietary SUPA® alloys
These materials provide corrosion resistance, high tensile strength, and resistance to sulfide stress cracking, ensuring long service life in aggressive downhole environments.
Precision Manufacturing & Full Traceability
Central Wire Slicklines are produced in the USA and United Kingdom using advanced manufacturing processes to ensure:
- Continuous, weld-free construction
- Bright surface finish for improved performance
- Consistent mechanical properties
Each slickline is supplied with a Certificate of Conformance, detailing:
- Mechanical properties and breaking load
- Alloy chemistry
- Full traceability
Independent third-party verification to EN10204 standards is available when required.

Material selection depends on well conditions:
- Duplex and super duplex alloys for high corrosion resistance
- Nickel alloys for extreme sour environments
- Stainless steel for general well conditions
Slickline FAQs
What is slickline used for?
Slickline is used in oil and gas wells for downhole operations such as measurement, tool deployment, and well maintenance.
What is the difference between slickline and wireline?
Slickline is a single-strand wire used for mechanical operations, while wireline can include multi-strand or electrical cables for data transmission.
How long can slickline be?
Slickline can be manufactured in continuous lengths up to 40,000 feet.
What materials are used in slickline?
Slickline is typically made from stainless steel, duplex, and nickel alloys designed for corrosion resistance and strength.
What is EN10204 certification?
EN10204 is a standard that verifies material properties and compliance through certified documentation and testing.
