Corrosion waits for no one. A refinery shutdown is a vulnerable time for austenitic stainless steel equipment. Without the guidance found in , you risk irreversible Stress Corrosion Cracking that could lead to costly repairs or, worse, safety hazards.

AMPP - The Association for Materials Protection and Performance NACE SP0170-2018

Unlike nitrogen purging, this method permits safe personnel entry for inspection and mechanical maintenance, provided the firebox or internal atmosphere is constantly monitored. 4. Heater Tube and Firebox Maintenance nace sp0170 pdf

During circulation of the alkaline wash, the pH of the effluent must be regularly checked. It must remain highly basic (pH > 9). If the pH drops, it indicates that acids are actively neutralizing the solution, and more soda ash must be added.

The standard is now managed by (Association for Materials Protection and Performance), formed by the merger of NACE International and SSPC.

Typically involves a solution of 1% to 2% sodium carbonate (soda ash, Na2CO3cap N a sub 2 cap C cap O sub 3 ) dissolved in potable water. Corrosion waits for no one

The standard (currently NACE SP0170-2018 ) is a critical standard practice for the petroleum refining industry, focusing on the protection of austenitic stainless steels and other austenitic alloys from Polythionic Acid (PTA) Stress Corrosion Cracking (SCC) .

: Special considerations for refinery reactors.

Marina Vasquez was a corrosion engineer, which meant she spent most of her time thinking about things falling apart. Metal rusting, pipelines thinning, bolts fusing into useless lumps of iron oxide. Her job was to slow down entropy. Digital copies are sold via the ANSI Webstore

These are authorized resellers of technical standards. They offer the NACE SP0170 PDF in various formats, including multi-user licenses for corporate use.

Tonight, entropy had a name: .

The current version, , was published on September 10, 2018, by NACE International (now part of AMPP ). Understanding PTA SCC

Having access to the PDF allows you to:

PTA can cause rapid, intergranular stress corrosion cracking in sensitized austenitic stainless steels.
