We Aries, extends our services in Corrosion testing focusing to provide our clients with early detection of corrosion and minimizing the failures in materials that are subjected to face corrosion. It’s a challenging scenario in many industries especially in oil and gas fields that are caused by corrosion effects. It’s an apt option to test these materials before that are being installed. So we would like to recommend Corrosion testing and proper evaluation by our team as per recognized standards.
The metal and alloys are made up of grain, in micro level the structure is separated by grain boundary. Intergranular corrosion is preferential attacks on the grain boundary where grain remain largely unaffected. This type corrosion occurred due to segregation of impurity (precipitation of nitrides, carbides, and other intermetallic phases, such as sigma phase) on the grain boundary. Such precipitation can produce zones of reduced corrosion resistance in the immediate vicinity.
This mainly occurs with incorrect heat treatment service, materials are liable to crack or fail by intergranular corrosion (IGC) much more rapidly than properly treated materials. In any case the mechanical properties of the structure will be seriously affected. Aries can carry out testing as per ASTM A262, ASTM A923, ISO 3651 and ASTMG28 standards.
During services if the material exhibits localized pits or gaps on its surface, pitting or crevice corrosion may be the culprit. Pitting corrosion is characterized localizes pit holes, and crevice corrosion occurs where two materials meet. Material resistance to pitting and crevice should be assessed before its usage. Aries provide pitting and corrosion test based on ASTM G48 .
Aries laboratory is fully equipped with latest methods of testing in compromise with relevant standards of testing. We perform Sulphide Stress Cracking (SSC) testing of metals subject to cracking with simultaneous effect of tensile stress and corrosion in the presence of wet media and H2S environment as per NACE TM 0177 standard.
As per this test, the metals are subjected to tensile stresses for resistance to cracking failure in low-pH aqueous environments containing hydrogen sulphide (H2S).This type of corrosion is hazardous and often unpredictable so its suggested to have proper inspection of your materials to ensure quality and endurance.
We performs and evaluate carbon steel, low alloy steel and corrosion resistant alloys for sour service applications as per,NACE TM 0177 standard methods: Tensile Test, Bent-Beam Test & Ring Test. We execute Hydrogen Induced Cracking (HIC) testing to evaluate the susceptibility of low alloy steel and carbon steel to hydrogen embrittlement. Hydrogen Induced Cracking (HIC) testing is recommended to evaluate the resistance of pipeline and other materials to hydrogen induced cracking corrosion caused by hydrogen absorption from aqueous sulphide corrosion. The test is duly performed in accordance with NACE TM0284-2011. After the test the specimens are evaluated, examined microscopically and cracks if present, are reported and their ratios CSR (Crack Sensitivity Ratio), CLR (Crack Length Ratio), CTR (Crack Thickness Ratio) are calculated.
Heat treatment is carried out to alter the mechanical and physical property of the metals. The controlled heating and cooling of metals allows us to achieve desired mechanical property. Heat treatment is also carried out due to manufacture process such as welding, hot forming etc. to regain its material property.
Aries can help to develop heat treatment cycle to achieve desired property of material with precise heating and temperature control. We are helping to develop in heat treatment cycle such as solution annealing, quenching, tempering etc.
Residual stresses are as those stresses that remain in a body after removing the external load. These stresses influence the behaviour of mechanical components and can affect their structural and dimensional stability as well as the fatigue and fracture resistance of the materials. A residual tensile stress actually facilitates crack propagation and therefore reduces the fatigue life of a mechanical component. Residual stresses limit the loading capacity and safety of mechanical components during operation and in certain conditions it is necessary to know the quantity of those stresses.
Virtually all manufacturing and fabricating processes — casting, welding, machining, moulding, heat treatment, etc. introduce residual stresses into the manufactured object. Another common cause of residual stress is in-service repair or modification. In some instances, stress may also be induced later in the life of the structure by installation or assembly procedures, by occasional overloads, by ground settlement effects on underground structures, or by dead loads which may ultimately become an integral part of the structure.
Sometimes alone and some-times in combination with other factors, unaccounted for residual stresses have caused the failure of major bridges, aircraft, ships and numerous smaller structures and devices, often with substantial loss of life. At other times, residual stresses are deliberately introduced to provide beneficial effects, such as in pre-stressed concrete, shot-peening and cold hole-expansion.
Aries have the capability to quantify the residual stress using non-destructive portable equipment. On site field measurement and laboratory-based measurement also can be carried out using this NDT method.
The presence of high residual stress in Railway wheels & Crane wheels are the main causes of cracks that may result in severe issues during the wheel’s services life.The Railway industry and other vehicle industries is required to ensure that stress levels present in wheels are with acceptable limits defined by the category of the wheel under study. A premature diagonosis can prevent dangerous and costly situation. We are using EMAT technology as a solution for measurement of residual stress in wheels by a reliable easy and fast method.
