Frequently Asked Questions
The line is specifically engineered for strip steel grades Q195 through Q345, supporting thicknesses from 2.0mm up to 5.0mm.
We utilize a computer-controlled flying saw machine equipped with a precision speed measurement system and DC driving motors to ensure accuracy within ±3mm.
The straightening machine eliminates internal stresses and bending that occur naturally after the forming and welding stages, ensuring the pipe is perfectly straight.
This specific configuration is optimized for welding pipe diameters between φ76mm and φ89mm.
The cage looper acts as a raw material buffer, decoupling the uncoiling process from the forming machine to ensure continuous, uninterrupted production.
By using high-grade GCr15 and 40Cr materials that are quenched and tempered, our rollers offer superior hardness (HRC 60-65) and a significantly longer service life.
