Manufacturing Process & Quality Control

Advanced Manufacturing Processes:

Seamless Pipes: Produced using advanced extrusion, cold rolling, or cold drawing processes, ensuring precise dimensions, uniform wall thickness, and excellent mechanical properties.

Welded Pipes: Manufactured using high-quality TIG/GTAW welding processes, ensuring weld strength matches the parent material, accompanied by rigorous weld inspection and heat treatment to relieve stress.

Rigorous Quality Testing (Test Requirements):

Raw Material Inspection: Chemical Composition Analysis (Spectro Test).

Dimensional & Visual Inspection: Dimension Inspection, Visual Inspection.

Non-Destructive Testing (NDT): Eddy Current Test, Ultrasonic Testing (UT), Radiographic Testing (RT - for welded pipes).

Pressure Testing: Hydrostatic Test, Pneumatic Test (Air underwater pressure Test).

Mechanical Properties Testing: Tension Test (Elongation, Yield Strength, Tensile Strength), Impact Test (Sharpy Impact Test), Hardness Test, Flattening Test, Flaring Test.

Special Tests: Intergranular Corrosion Test (for specific alloys and applications), PMI (Positive Material Identification).

Traceability: Comprehensive Material Reports and traceability are provided, with support for independent third-party certification.
