SUPERNOVA 250 Slickline

UNS S32750 WN 1.4410 PRE: >42

In addition to excellent mechanical properties (minimum breaking load), Supernova 250® Super Duplex slicklines have exceptional resistance to chloride and sulphide stress corrosion cracking, acid corrosion and crevice corrosion making it suitable for a wide range of corrosive sour well environments.

Manufactured in Switzerland and certified to 9001: 2015 all Supernova Slicklines are fully traceable, 100%
Weld Free, 100% Eddy Current Tested and Wrap Tested.

All are produced with a consistent, tightly controlled surface finish, wire helix and wire cast for optimal
spooling and in-service performance.

Key Characteristics
 

• Outstanding resistance to chloride-induced stress corrosion cracking (SCC) and sulphide-stress cracking (SSC) in sour-gas conditions

 

• Resistant to SSC in sour, condensed waters with 0.2 bar partial pressure of H2S

 

• Outstanding corrosion resistance along with superior pitting resistance

 

• High break loads with good ductility

 

• May be used in temperatures up to 300°C

 

• Good atmospheric corrosion enabling safe marine / offshore storage

 

• High resistance to abrasion, fatigue and corrosion fatigue 

 

• Very resistant in sweet wells, to corrosion by CO2

Corrosion Resistance PRE Number (PRE)

PRE: >42
 
PRE = Cr + 3.3 x Mo + 16 x N

Pitting Resistance Equivalent numbers (PRE) are a way of comparing the pitting corrosion resistance of
various stainless steels based on the levels of chromium, molybdenum and nitrogen they contain with the most frequently used formula and Novametal’s preferred method for calculating PRE numbers being :

PRE = Chromium + 3.3 x Molybdenum + 16 x Nitrogen.

Some suppliers may use a factor of 30 x N, resulting in a marginally inflated PRE Number
