ASTM International, 655 Barr Harbor Drive, PO Box C755, West Conshohocken, PA, 69978-7959 USALearn how the upcoming changes to E6577 will impact the Environmental Site Assessment and Transaction Screen Process. Other failure modes are caused by changes in water chemistry due to leaks in other parts of the system, corrosion from unexpected sources, the impact of improper lay-up practices, and the effect of corrosion product transport to other parts of the system.
When it s time to select new condenser tube material, you ll need to consider the projected operating environment and failure mechanisms that material will be subjected to. TCR offers a comprehensive range of material testing services for corrosion problems that include:
Inter-granular Corrosion of Ferritic, Austenitic Ferritic-Austenitic (Duplex) Stainless SteelIntergranular corrosion of stainless steels per ISO 8656 Method A, B, C Watch this 95-second new video that talks about what ASTM International does in plain language, showing how standards impact us in labs, at work, and in our daily lives.

Astm 54b table Free DownloadBecause the total concentration of all contaminants in the steam cycle water chemistry is usually measured in parts per billion, steam cycle water chemistry is normally considered nonaggressive to most alloys. ASTM's corrosion and wear standards provide the appropriate procedures for carrying out corrosion, wear, and abrasion tests on specified metallic materials and alloys.
Unauthorized reproduction or linking forbidden without expressed written permission. The environment in which the tubes will operate, now and in the future, also must be described in the specifications.
Duplex and ASTM G48 A Test Metal and Metallurgy
Stainless steels and titanium are resistant to these gases, but the copper-based alloys can be attacked by ammonia admiralty brass and aluminum brass are the most susceptible. This action might not be possible to undo.
Astm D1621 Free DownloadAs discussed in Optimizing Condenser Tube Selection, earlier in this issue, a plant engineer has several materials from which to choose when specifying a replacement set of condenser tubes. According to NACE, the worldwide corrosion authority, the total annual cost of corrosion to the Oil Gas production industry is estimated to be $6.877 billion per annum.
Senior technicians are available to provide consulting and advisory services on corrosion prevention and control services including material selection either in the laboratory or on-site inspection. The most important tube failure mechanisms typically result from different forms of corrosion and erosion.
However, by actively condensing the steam, the condenser will concentrate gases that don t condense at the same temperature as the steam. Join your peers on the Internet's largest technical engineering professional community.

The ammonia can cause two types of failures: ammonia grooving and stress corrosion cracking (Figures 6 and 7).
TCR Engineering Mumbai Corrosion Testing NACE ASTM
Find all of your industry-related resources in one spot. These tests are conducted to examine and evaluate the behavior, susceptibility, and extent of resistance of certain materials to stress corrosion cracking, cavitation erosion, intergranular corrosion, pitting and crevice corrosion, cyclic potentiodynamic polarization, exfoliation corrosion, atmospheric and galvanic corrosion, liquid impingement erosion, crevice repassivation, sliding and rolling friction, surface scratching and lubrication, cavitating liquid jet erosion, and hydrogen embrittlement.
9 of ASTM E7898. This massive cost to this vital industry sector can be minimized through a combination of effective corrosion management programs and by working with corrosion testing experts like Element to ensure the assets deployed are safe and will perform as expected once deployed in the field.
TCR Engineering Services undertakes a wide range of corrosion and stress corrosion tests as per ASTM, NACE or those that are specific to an individual client’s requirements.
