Mechanical tests provide information about the behaviour of the material when it subjected to applied forces. The mechanical stresses may be continuous or instant, uniformly applied on a surface or localized in a point, carried out at room temperature or under cold or hot conditions.
Chemical analysis allows to determine the chemical composition of the material and classify it through different analytic techniques. These tests can be performed in the laboratory’s facilities or where components and materials are placed or installed.
Metallographic examinations allow to study in deep the material’s structure thanks to magnification techniques giving useful information about grains, inclusions and microstructure configuration. In these kind of tests, personnel’s experience and laboratory’s equipment are of the utmost importance.
Corrosion tests consist in etching metal specimens with specific chemicals according to the conditions stated by the standards. The reactions that occur are electrochemical phenomena revealing the material’s resistance against environmental aggressive agents and toward wear in severe service conditions.
Corrosions and stress-corrosion tests in hydrogen sulphide solutions simulate the behaviour of the material in severe service conditions, that are typical for Oil&Gas industry. In this field NACE institute represents the highest authority for test methods standard and materials specifications.
In order to evaluate the hydrogen induced disbonding phenomenon, carbon steel specimens overlayed with stainless steel are subjected to typical refineries environmental conditions, characterised by the presence of gaseous hydrogen. This test allow to detect and evaluate possible disbonding or delamination between base and cladded materials due to the accumulation of molecular hydrogen in the region of the metallurgical bond at the interface between the steel and stainless alloy surface layer.
Non destructive testing can detect defects without damaging the material or affecting its operating performance. Components may be tested both at the laboratory facilities or where they are manufactured or installed.
Failure analysis allows to determine the causes of a component’s failure or malfunctioning. Destructive and non destructive tests support Sider Test in providing a quick and accurate diagnosis of the root cause of the failure and suggesting metallurgical solutions in order to prevent or tackle the recurrence of the damaging phenomenon.
Thanks to some heat treating furnaces the laboratory can simulate tempering, stress relieving, annealing, normalizing, quenching, solution annealing and step cooling upon the test samples.
For dimensional inspection Sider Test is equipped with a wide range of insturments including a coordinate measuring machine.
The laboratory can carry out customized tests based on the specific technical requirements of the customer. Special testing equipment may be designed and produced in order to simulate the particular service conditions of the components as best as possible
One of the laboratory’s facilities includes a large and up to date workshop for the machining and preparation of the specimens. These services are also available to companies with their own internal testing laboratory.
