Quality
The Onus is Quality…
As an ambitious production facility, we take our responsibility towards our Customers and our part in building a credible economic portfolio of the Country, very seriously. The focus is always centred on continuously improving the Quality of our Products and Services through effective R & D. The raw materials are checked for surface defects and physical anomalies before they are moved into the production phase. We adhere to a strict code of testing, in compliance with International Standards, involving the bending, full flattening, drift expanding and other required tests as performed on Sample tubes before the finished product is marked fit for Industrial consumption.
Eddy Current Testing
A reliable method to detect surface and conductive flaws in Steel tubes using the principal of Electromagnetic Induction. Even minute cracks in or near the surface of the tubes can be detected. A badly finished tube gives out a bad reading while the tube surfaces need minimal preparation for this test. At Suresh Steels, Eddy current testing is our first line of Quality Analysis.
Universal Testing Machine (UTM)
At Suresh Steels, the UTM is used to test the tensile stress and compressive strength of the Steel tubes. The machine progressively applies increasing load on the sample tube- while the control systems and its associated software record its corresponding effects.
Drift Testing
This test is also called ‘Flare’ testing. This is a robust test to measure the ductility of Steel tubes. The end of a typical steel tube is expanded until a specific diameter is achieved that corresponds to a specific angle of drift. A steel tube is considered to have passed the Drift Testing if it shows no sign of cracks, splits or other stress marks at the end of this test.
Hardness Testing Machine
The ultimate definition of Quality in terms of a Steel pipe is its hardness- the ability to withstand stress and external pressures. We ascertain this feature by using the Hardness Testing Machine. A point based indenter is pressed against the surface of the Steel tube to detect its depth of penetration. At our testing facility, a standard Sphero-conical diamond is used with a 150kg load.
Full Flattening Test
This test is applicable to Steel Tubes and involves the process of deliberate flattening of a sample steel tube. When flattened, a typical Suresh Steels’ product doesn’t develop cracks, splits or other stress marks thereby passing this stress test. Strenuous international standards are adopted to determine the degree of flattening and the acceptable changes resulting on the sample steel tube.
Elongation Testing
This test is utilised to determine the ductility or elasticity of the Steel tubes as produced at Suresh Steels. A sample steel tube is stretched and the increase in its length before breaking or rupturing is compared against its original length before the stretching. This increase in length is termed as ‘Elongation’ and the greater its value; the more ductile the steel tube is considered.
Crushing Test
This test is also called ‘Upsetting test’ and involves the flattening of a sample Steel tube, with the downward force applied at a 90® angle. The force is applied until the opposing walls of the steel tube meet to determine the ductility of the sample tube. Strenuous international standards are adopted to determine the applicable force and the resultant changes on the sample steel tube.
Final Inspection
The final step of our Quality Analysis process involves a final, comprehensive Inspection. Any visual or dimensional inaccuracy that might have been overlooked by the automated systems is easily sorted out by our expert team of analysers.
