Improve H2S, mercaptan, sulfur, mercury, ammonia, and active compound sampling performance while reducing operating cost with Dursan™.
Dursan's superior inertness and extreme corrosion resistance make it the ideal coating for harsh environments found in:
- Chemical process industries
- Refining
- Oil & Gas exploration and transport
|
- Stack monitoring, CEMS
- Offshore/Marine
|
Dursan™ CVD coating technology.
Dursan™ is a proprietary patent pending coating designed to improve the inertness, hardness, and corrosion resistance of stainless steel, alloys, glass, and ceramics. Dursan™ will deform with tubing or part surfaces, allowing a leak-free seal or radius bend while maintaining high dimensional tolerances.
Dursan ™offers superior wear resistance and durability under extreme conditions.
Dursan's scratch resistant, high temperature, pH stable and hard surface is the logical choice for harsh environments. Dursan™ remains inert under the most extreme conditions (Click here for a complete coating specification guide):
- Temperature limit: -210c to +450c
- Acid/base exposure: pH 0 to 14
- Maximum pressure: Limited by the base material
- Vacuum service: Unlimited
- Wear resistance: Excellent
Comparative wear studies show Dursan™ is significantly more wear resistant than uncoated 316 stainless steel. (Table 1)

Dursan's tough, intermolecular coating stands up to abrasive environments while maintaining a flexible, and installation friendly surface.
Dursan's 450°C maximum temperature limit and acid/base pH stability offers durability in applications normally reserved for the most expensive super alloys. Dursan™ applications include:
- Stack gas testing
- CEMS
- Refinery
|
- Downhole sampling
- Produced water
- High purity/semiconductor
|
Dursan's inert surface prevents interaction of active compounds like H2S, mercaptan, SOX, mercury compounds, ammonia and others.
H2S stored for only a day in a stainless steel sample cylinder is completely adsorbed, while the Dursan™ coating maintains sample integrity for 3 days or more. Dursan's inert surface assures superior sample reliability; saving thousands by eliminating sample errors like:
- False positive/negative response
- Sample adsorption
- Lost response due to moisture interaction
- Sample loss due to active sites
- Sample loss due to corrosion related contamination
Dursan™ is the coating choice for improved corrosion resistance and durability. Improve corrosion resistance by up to 200X!
Dursan™ extends the life of stainless steel in harsh, corrosive environments. Laboratory testing proves Dursan™ is the ultimate high durability, corrosion resistant surface.
Comparative ASTM G31 hydrochloric acid immersion testing of Dursan™ coated and uncoated stainless steel coupons demonstrate Dursan's exceptional corrosion resistance (Table 2).

After 24 hours of immersion in 18% hydrochloric acid the Dursan™ coated 304SS coupon exhibited minimal corrosive attack, while the uncoated 304SS coupon is severely corroded.
Dursan™ minimizes process contamination by preventing corrosive interaction with stainless steel; eliminating potentially harmful contamination of process streams.
Summary
Dursan™ is ideal for environments demanding inert, corrosion resistant, high durability coatings. Test data show Dursan's inert surface allows low ppm sampling of active compounds such as H2S, mercaptans, SO2, mercury and many others. Dursan™ improves the corrosion resistance of stainless steel while reducing the overall system maintenance cost and sampling reliability.
