HISTORICAL DOCUMENT. This standard test method provides descriptions of the measurement techniques and cautionary measures most commonly used on underground and submerged piping other than offshore piping to determine whether a specific criterion has been met at a test site. This standard contains instrumentation and general measurement guidelines. It includes methods for voltage drop considerations when structure-to-electrolyte potential measurements are made and provides guidance to minimize incorrect data from being collected and used. This standard is maintained by Task Group 020.
Testing procedures on a buried or submerged steel, cast iron, copper, or aluminum pipeline. Instrumentation and measurement guidelines. Voltage drop considerations for pipe-to-electrolyte measurements.
HISTORICAL DOCUMENT. Two methods of evaluating relative carburization resistance of alloys used in ethylene cracking furnace tubes. Standardized data that allows evaluation of tube supplier carburization data.

In the present study, corrosion behavior of base metal (BM), all-weld-metal (AWM) and heat-affected-zone (HAZ) samples of C-276 (UNS N10276), C-22 (UNS N06022) and C-2000 (UNS N06200) alloys were evaluated in concentrated hydrochloric (HCl), sulfuric (H2SO4) and nitric acid (HNO3).
Any time a Suspended Scaffolding is used one key element of the system is the development of an adequate safety and rescue plan. By following the ACE strategy, you can identify the critical elements of an effective fall protection safety plan.
This paper will introduce UNS N08830 - a new Ni-Fe-Cr-Mo-N superaustenitic alloy with a microstructural evaluation as well as corrosion and mechanical test results. exceptional pitting and crevice corrosion resistance, high strength.
UNS S31400 stainless steel was tested as a reactor material for a thermal cracking process of agricultural, silvicultural, industrial and anthropogenic resources containing HCl. This material was chosen as it offers proper corrosion resistance in hot gases besides a good price and a high availability.
Pre-construction primers (also known as shop primers or pre-fabrication primers) are very thin films applied to blast cleaned steel plates and shapes to provide preservation of the blasted steel during the shipbuilding or construction process. SSPC is developing an industry guide document containing information regarding the use of pre-construction primers (PCP) on structural steel in shipbuilding.
Fire is the biggest threat for the crews in aircraft, ships, submarines, and land vehicles. As a result of such threats there have been use of fire/flame retardants coatings increased exponentially to curb economic and social consequences of fire [1]. There are various types of coatings available to fight against the fire. Two classes of fire protection technologies are being used currently, 1) Fire retardant and 2) Fire resistant. Fire retardant coatings are passive fire protection coatings where such coatings can slow down the spread of the flames allowing more time for evacuation and firefighting. Fire resistant coatings typically inhibiting the flame penetration or do not ignite upon in contact with fire [2].
