At Jindal Tubular, we have instilled quality as a habit towards our product, processes and people by implementing continuous improvements and education. Our quality system is accredited by API Q1 and ISO 9001 standards. Further, at Jindal Tubular, we have created internal processes and controls which are more stringent than any other global quality standards. Jindal Tubular USA is committed to improving product quality, efficiency and customer satisfaction.
Product monitoring and measuring is performed throughout the production process through a series of inspections. Product conformity is verified through a series of test such as Mechanical (performed by lab personnel), Hydrostatic, Ultrasonic, Radiography, Magnetic Particle and Residual Magnetism testing. Dimensional and final visual inspections are performed prior to product shipment.
Material integrity and quality control are at the very heart of the Jindal Tubular pipe manufacturing process. Every pipe will undergo very rigorous destructive and non-destructive integrity testing, as well as each pipe is visually inspected for surface defects and welding consistency inside and out.
In our best-in-class mechanical & coating testing laboratory we complete an independent analysis on coil as well as pipe sections to ensure that the components of the steel are of the quality our customers deserve and demand. Through this testing we can guarantee our customer that our pipe meets or exceeds the required chemical and mechanical properties.
Different Methods of Testing
Through this testing we can guarantee our customer that our pipe meets or exceeds the required chemical and mechanical properties. Those tests include:
Tensile Test: Used to determine the overall strength of steel.
Guided Bend Test: Used to test the quality of a weld seam.
Charpy Impact Test: Used to determine overall toughness of steel including absorbed energy and brittle appearance.
Computerized Hardness Test: Used to verify steel hardness values.
Chemical Analysis Test: Used to determine the chemical analysis of steel.
Drop Weight Tear Test: Used to determine point of brittle fracturing and/or cracking in steel.
Cathodic Disbondment: Cathodic Disbondment testing provides an assessment of the resistance of the coating to disbondment when subjected to cathodic protection.
Adhesion: Adhesion testing is necessary to ensure coating will adhere properly to the substrates to which it is applied.
Interface Contamination: Contamination testing is performed to identify an excessive amount of foreign contaminants.
Interface Porosity: Porosity testing is performed to determine the degree of porosity or voids in the applied coating.
Cross-section Porosity: Cross-section Porosity testing is similar in nature to Interface Porosity Testing only rated on a separate scale.
Gel Time: Gel Time testing is performed to determine the length of time a coating powder takes to gel at a specified temperature.
Flexibility: Flexibility testing is performed to determine flexibility of the coating during transportation and field bending.
Differential Scanning: Scanning Calorimetric or DSC is used to determine the glass transition temperature and the exothermic heat of reaction of epoxy powders and coating.
Impact Resistance: Impact Resistance testing is performed to provide a method for assessing the coating’s resistance to damage by impact from a falling weight.
