Seamless Boiler Pipes

1. Raw Material Preparation: 

Selection of high-quality steel billets (carbon/alloy/stainless steel) to meet seamless boiler pipe standards.

2. Piercing: 

Hot piercing of billets to form hollow shells—foundation for seamless structure.

3. Hot Rolling/Expanding: 

Precision hot rolling or expanding to achieve target outer diameter and wall thickness.

4. Sizing & Straightening: 

Calibration to strict dimensional tolerances for roundness, straightness, and surface smoothness.

5. Heat Treatment: 

Normalizing, quenching, and tempering to enhance high-temperature resistance and mechanical stability.

6. Surface Treatment: 

Descaling, polishing, and optional anti-corrosion coatings to resist oxidation and regional environmental stress.

7. Testing & Inspection: 

Hydrostatic pressure testing, ultrasonic testing (UT), dimensional verification, and chemical composition analysis.

8. Finishing: 

Cutting to standard or custom lengths, with plastic caps on ends to protect against contamination.

Exceptional High-Temperature Resistance: 

Withstands 600°C+ heat without deformation, ideal for superheaters and industrial boilers.

Superior Pressure Bearing Capacity: 

Seamless construction eliminates weak points, ensuring reliability under extreme pressure.

Corrosion & Oxidation Resistance: 

Stainless steel and alloy grades resist steam, chemicals, coastal humidity, and desert air erosion.

Efficient Heat Transfer: 

Smooth internal/external surfaces minimize scaling and maximize thermal efficiency.

Climate Adaptability: 

Performs reliably in extreme temperatures (-10°C to 600°C+) and harsh industrial environments across target regions.

Long Service Life: 

Resists thermal fatigue, reducing maintenance and replacement costs for industrial facilities.
