Carbon Steel Pipe Nace Mr0175 Material

Tubos India is one of the large manufacturers for high quality NACE MR0175 Pipes. NACE was established since 1943, full form is National Association of Corrosion Engineers. MR0175 is the standard of material requirements for H2S containing gas and oil production and equipment. NACE MR0175/ISO 15156 provides common rules, gives requirements and suggestions to select qualified steel materials, that served in equipment used in gas and oil production and in natural gas sweetening plants in H2S-containing environments. NACE MR0175/ISO 15156 are resistant to crackings such as:

• Sulfide stress cracking (SSC)
• Stress corrosion cracking
• Stepwise cracking
• Soft zone cracking
• Stress-oriented hydrogen-induced cracking
• Hydrogen-induced craking
• Galvanically induced hydrogen stress cracking.

NACE MR0175 Chemical Composition has limits for content Sulfur (S ≤ 0.002%), Phosphorus (P ≤ 0.020%) and Carbon (C ≤ 0.10%). The NACE MR0175 Specification wants to prevent SSC in downhole environments, storage batteries, piping systems, desulphurization systems, etc. which take the material upto the fence of the refinery. For the year between 1975 and 2003, many engineers extend the MR0175 concepts and applied them to the refinery situation (along with the help of RP0472, which even preceded MR0175 and addresses welding relateds and H2S cracking in refineries).
