This work analyzes the premature corrosion failure of a welded AISI 304 stainless steel (SS) pipe network in well water (WW) for 6 months. Laboratory tests were performed to analyze the corrosion behavior and to identify and distinguish the genera of bacteria. Pipe specimens were analyzed using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, open circuit

      Microbiologically Influenced Corrosion Attacks Welds Before Component Is Put Into Service. About 200 feet of 2-inch, schedule 10, Type 304 stainless steel transfer piping was installed to replace a bulk handling operation. The product, which could produce nitrous oxide as a breakdown product, was one that had been routinely handled at the plant Case Study:Pitting and Stress Corrosion Cracking in Heat Nov 12, 2011 · A jacketed underground pipeline made of 304 stainless steel tubing to transport utility water in a petrochemical plant at ambient temperature was perforated after few months of operation. Perforation started preferentially at the outer bottom surface of the pipe in the weld heat-affected zones where the insulating coating was damaged. Detailed microstructural characterization was carried out

Problem, rust appearing after several days in an open and exposed lay down area. Corrosion Resistance of Stainless Steels in Soils and in 3.4 Microbiologically Induced Corrosion (MIC) Microbiologically induced corrosion (MIC) refers to corrosion that is induced by the presence and activities of microorganisms and the products produced in their metabolism. Especially the sulphate reducting bacteria (SRB), which occur under anaerobic conditions can play a major part in soil corrosion.

Corrosion investigation of transformer. Corrosion evaluation of valve. Constant current stress SSRT analysis in H 2 S atmosphere. 4-point bending test of brass. FEM analysis of residual stress induced by repair welding Abstract Repair welding is widely used to repair defects such as fatigue crack and stress corrosion crack in metal structures for prolonging their service lives. However, the residual stress induced by repair welding potentially threatens the safety of the repaired weldments, especially stainless steel pipe structures and pressure vessels used in nuclear power plants.

        How the wet HS affect the steel pipeline?

        Mar 23, 2021 · Stress corrosion cracking (SCC) is a kind of environment-induced fracture (EAC), which is a common environment-induced crack dispersed on the outer surface of the steel pipeline. According to statistics, the stress corrosion cracking of stainless steel in wet state corrosion failure accident is even as high as 60%, ranking first in all kinds of Liquid Metal Embrittlement of Austenitic Stainless Steel hot surface of a 316L stainless steel pipe. The resulting LME-induced cracking in the pipe material caused a large hydro­ carbon leak which ignited to cause the explosion (Ref. 5). In the second in­ stance, extensive cracking of Type 300 series (304, 316L) stainless steel oc­ curred during the welding of pipe

        pipe consisting of an inner layer (the liner) and outer layer (backing steel). The liner is made of corrosion resistant alloy (CRA) such as Alloy625, 304 and 316L stainless steel (SS) whilst the backing steel is made of low-cost carbon steel [1]. Lined pipe welding is a complex process requiring two sequential welds. The liner is Stress Corrosion Induced Failure of 316L Stainless Steel PipeThe interaction between mechanical stress and the presence of chlorine and sulfur results in increasing susceptibility of austenitic stainless steel to cracking. In general, the corrosion resistance of austenitic stainless steels to SCC depends on the following factors[3]:1) Alloying composition. Increasing nickel and molybdenum content of austenitic stainless steel enhances the resistance to SCC, 2) Tensile

The problem of sensitizing reaction of austenitic In the temperature range of 950-1450°F, chromium carbide tends to precipitate at the grain boundary of austenitic stainless steel. Any exposure or thermal excursion within this temperature range during metal manufacture and use may cause sensitization of the austenitic stainless steel.(What is the difference between stainless steel of five kinds of material?
