TEST REQUIRED

Conduct a comprehensive suite of tests: Chemical Analysis, Mechanical Test, Visual Inspection, Tension Test, Dimension Check, Bend Test, Flattening Test, Impact Test, Drop Weight Test (DWT), Non-Destructive Testing (NDT), Hydrostatic Test, Hardness Test, ensuring unparalleled quality and durability.

PRODUCTION PROCESS

Unveil our Hot Rolling Seamless Steel Line Pipe Manufacturing Process, an epitome of precision engineering:
Embark on an intricate journey starting with Rolled Round Billets which undergo thorough Examination. The billets are then Cut Off and proceed to Heating. With precision, Piercing and Elongation occur, followed by Slight Tension Reducing. The process continues with Straightening and Corp End Cutting Off, all while ensuring a Visual Inspection. Advanced NDT techniques and Hydrostatic Tests guarantee standards. The Ends are Processed, followed by meticulous Product Inspection, Painting, and Marking, before a final step of Packing and Warehousing.

PRODUCTION PROCESS

Explore the Cold Drawn (Rolled) Seamless Steel Pipe Manufacturing Process, a testament to our commitment to excellence:
Starting with a Mother pipe, typically from hot rolled pipe, it undergoes Inspection and Annealing. Ends are treated meticulously through Hitting and Drilling holes. The process advances with Pickling and Grinding, followed by Phosphorization (Annoit) enhancing quality. The pipe then subjects to Cold Drawn (Rolled) process, followed by Degreasing and Cleaning. A critical Heat treatment (Solution treatment) ensures resilience, and Straightening perfects alignment. Rigorous Hydrostatic testing confirms durability, with Painting and Marking preparing it for Warehousing, the final destination of excellence.
