Horizontal spiral strip accumulator is installed between welder and forming mill. It provides continuous steel strip supply during coil change, shearing and butt welding. It guarantees non-stop operation and improves efficiency & product yield for ERW and OCTG pipe production lines.
Dedicated Shear End Welder for OCTG pipe production lines. It trims irregular sections at steel strip heads and tails, then conducts precise butt welding to connect successive coils. Welded strips are sent to the accumulator, ensuring stable material supply and non-stop operation for OCTG manufacturing lines.
Our strip flattener is key pre-forming auxiliary equipment for OCTG & ERW tube lines. Installed after uncoiler, it eliminates coil set, edge camber, surface waviness and residual stress of steel strips. It delivers flat, stable strip feeding to optimize forming and welding, ensuring consistent, high-efficiency production for the whole pipe mill line.
Our uncoiler is a core front-end unit for welded tube production lines. It receives steel coils from loading trolleys, stably supports heavy coils and performs continuous uncoiling. The steel strip is smoothly delivered to the strip flattener and downstream stations, fully preparing materials for subsequent tube forming and manufacturing.
Our φ114mm CNC threading machine specializes in OCTG product threading. It reliably processes API standard threads and premium connections with high precision and efficiency, well suited for oilfield and energy tubular manufacturing workflows.
Automated CNC OCTG ultrasonic flaw detection system for seamless & ERW oil casing, tubing. High-sensitivity UT detects longitudinal, transverse, oblique & laminar defects with synchronous precise wall thickness measurement, complying with API 5CT, API 5L for tube mill full volumetric NDT inspection.
High pressure multi-station hydrostatic testing machine serves seamless and welded pipes to detect internal defects. It uses radial large-gap or end face sealing and maintains standard pressure to check leaks. Dual auto/manual control ensures safe, reliable and eco-friendly operation; all test data is stored in database for traceability and inquiry.
Custom pipe end facing & chamfering machine built for high-efficiency steel pipe end processing. The all-in-one design covers facing and chamfering to meet production line pre-processing requirements. It features stable performance, high efficiency, superior precision and flexible operation, ideal auxiliary equipment for modern steel pipe manufacturing.
Our API OCTG Straightening Machines adopt full automation with integrated entry and exit conveyors. Heavy-duty structure ensures great rigidity and stable operation. It processes carbon steel, API and seamless pipes, fitting various diameters, wall thicknesses and line speeds, supporting both online and offline operation.
