This test involves applying a uniaxial load to a specimen until it fractures, allowing for the assessment of various material properties, including Ultimate Tensile Strength (UTS), Yield Strength, Elongation, and Reduction of Area.
Hydrostatic Test
Conducting hydrostatic tests on the steel pipes to check for sealing and pressure-bearing capabilities. Formula: P = 2St/D, where P is pressure, S is pipe wall stress as a percentage of yield strength, t is wall thickness, and D is diameter.
HIC & SSC Tests
Hydrogen Induced Cracking (HIC) and Stress Corrosion Cracking (SSC) Testing are essential for evaluating the crack resistance of steel pipes in specific environments, particularly in the oil and gas industry. HIC testing is primarily conducted to detect cracks induced by hydrogen, while SSC testing assesses the brittleness of materials under stress in corrosive environments.
Darbe Testi
Impact testing is a critical evaluation method used to determine the toughness and ductility of materials, particularly metals, under sudden loading conditions. This test helps assess a material’s ability to absorb energy and resist fracture when subjected to impact forces. Standard impact tests include the Charpy and Izod tests, which measure the energy absorbed by a material during fracture.
Hardness Test
Hardness testing is a critical evaluation method used to determine the resistance of a material to deformation, indentation, or scratching. It is an essential property for assessing the suitability of materials for various applications, particularly in manufacturing and engineering, including HB (BHN), HRB, HRC, and HV.
Flattening Test
The flattening test is a mechanical test used to assess the ductility and integrity of materials, particularly in welded joints and pipe sections. This test involves applying a compressive load to a specimen to determine its ability to withstand deformation without cracking.
Flaring Test
The flaring test is a mechanical test used to evaluate the ductility and integrity of pipe materials, particularly in welded joints. This test assesses a material’s ability to withstand deformation when subjected to bending or expansion, simulating conditions encountered in service.
Flanging Test
Flanging test is a mechanical test as per ISO 8494, DIN 50139, ASTM A370, which the end of a tube is bent by 90°. The test determines, through plastic deformation, whether tubes are suitable for flange formation. This test assesses a material’s ability to deform under stress without cracking, ensuring the reliability of flanged connections in various applications.
