The standard highlights the need for properly selected materials, particularly stabilized grades of austenitic stainless steels (e.g., 321 or 347) which are more resistant to sensitization. Importance of the 2021/Updated Standard

Hydroprocessing loops operate under deeply reducing conditions with high hydrogen sulfide ( nace sp0170 pdf 2021

: Covers austenitic stainless steels (300 series) and other austenitic alloys (e.g., Alloy 600, 800, 825) used in refinery services where sulfide scales can form. Protection Methods : : You can purchase or download the PDF

In the high-stakes environment of the oil and gas industry, a single drop of water can be a ticking time bomb. When that water mixes with hydrogen sulfide ($H_2S$) and stresses a piece of steel, the result is not just corrosion—it is cracking, potential failure, and catastrophic safety hazards.

The standard identifies several strategies designed to disrupt the conditions necessary for acid formation. These procedures are complex and must be executed by qualified personnel in accordance with site-specific safety protocols. 1. Environmental Control (Inerting) Protection Methods : In the high-stakes environment of

As of 2025, the official NACE SP0170 PDF 2021 costs approximately $150–$250 for members (less if you join AMPP). For a piece of equipment that costs millions, this is a trivial investment.

The system must remain pressurized under nitrogen for the entire shutdown. This strategy is perfect for units that do not require internal inspections or catalyst changes. 2. Alkaline Chemical Washing (Neutralization)

The most effective way to prevent PTA-SCC is to prevent the reaction between iron sulfide, oxygen, and water. Operators achieve this by filling and blanketing the equipment with high-purity .
