Documented Examples of Pipe Corrosion and Failure. CorrView International, LLC offers a series of photo galleries taken from 18 years of past ultrasonic piping investigations, which address the above and additional corrosion conditions. A review of the different types of corrosion is often helpful in initially determining the likely corrosion cause.
Carbon Steel - Jindal, ISMT Pipe & Stainless Steel PipeCarbon steel is steel with carbon content up to 2.1% by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states:Steel is considered to be carbon steel when:no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired
The sample pipe sections should be tagged and identified by type of material, location of pipe, age of pipe (if known), and date sample was obtained. The type of service (e.g., cold water, hot water, recirculating hot water, apartment, or home) should also be noted.
Defects Introduced into Metals During Fabrication and shrinkage and piping, inclusions, shrinkage and hot tears and others where the metal is solid and is being processed further:cracks, surface defects, residual stresses, embrittlement effects. The following section describes the broad classification of defects and describes their occurrence in

Welding Pressure Pipeliners and Piping Systemspipe should be ground to approximately the thickness of a penny [1/16 (1.6mm)]. The gap between pipes should be the same dis-tance, if possible. A 60° Included angle is used. Pipe End Cleaning Pipe rarely will be received in a condition suitable for welding. Generally, there will either be an oil or rust coating, or a coating to prevent
