Product Description
Product Overview
Manufacturing Process
Our seamless pipes are manufactured using advanced production techniques that ensure superior quality and dimensional accuracy:
- Production begins with solid steel rounds or billets heated to 2,300°F in walking-beam reheat furnaces
- Rotary piercing mills transform preheated rounds into tube shells through high-speed cross-rolling
- Mandrel mills provide precise OD sizing and wall thickness control
- State-of-the-art hot-wall measuring systems monitor dimensional accuracy throughout production
- 24-stand stretch-reducing mills achieve exact customer specifications
Quality Inspection
All large-diameter seamless pipes undergo rigorous electromagnetic inspection using Amalog-Sonoscope systems:
- Amalog magnetic circuits detect longitudinal defects on both inner and outer surfaces
- Sonoscope magnetic circuits identify circumferential defects
- Flux leakage detection via electromagnetic induction ensures comprehensive defect identification
Technical Specifications
Available in diameters ranging from 32mm to 630mm with wall thicknesses from 3mm to 60mm
Production Advantages
Three-Roll Pipe Mill Technology
Our three-roll mills deliver exceptional precision through repeated cross-rolling with mandrels, eliminating defects like scratches, ears, and green lines while maintaining production flexibility.
