Recently, a Russian client placed an order with Haihao Group for a batch of seamless steel pipes made from А333 Gr.6 material. This order highlights the stringent quality requirements and specific testing protocols that the client demands, which Haihao Group is fully equipped to meet.
А333 Gr.6 Seamless Steel Pipes
Detailed Specifications and Client Requirements
The order includes seamless steel pipes in two length specifications: 6 meters and 9 meters. The client has outlined a comprehensive set of requirements to ensure the highest quality and reliability of the pipes, including:
Sulphide Stress Corrosion Cracking (SSCC) Test: To ensure the pipes can withstand harsh environments where hydrogen sulphide is present.
Hydrogen Induced Cracking (HIC) Test: To evaluate the material’s resistance to hydrogen-induced cracking.
Fully Killed and Normalized Material: Ensuring the steel is fully deoxidized and subjected to heat treatment to refine its grain structure and improve its mechanical properties.
Chemical Composition and Mechanical Properties Assurance: Each pipe must meet the strict chemical composition and mechanical properties as per the А333 Gr.6 standards.
Macrostructure Control: A detailed examination of the pipe’s macrostructure to ensure there are no flaws or irregularities.
Flattening Test: To assess the pipe’s ability to withstand deformation without cracking.
Impact Toughness Test at -33°C: To verify the material’s toughness at low temperatures, ensuring it can perform in cold environments.
Hydrostatic Testing: Each pipe undergoes a water pressure test to ensure there are no leaks or weaknesses.
Ultrasonic Testing to 100%: Comprehensive non-destructive testing to detect any internal flaws or imperfections throughout the entire length of the pipes.
