Product Introduction

Overview

Our Round/Square/Rectangular Pipe FFX Direct Forming Group acts as the core forming assembly for high-frequency ERW pipe production lines. It gradually shapes incoming steel strip into a closed tubular profile via progressive roller bending deformation. The butted strip edges are then joined by a high-frequency induction welder to form solid, long-service-life weld seams. Freshly welded pipes are transported to the cooling zone for regulated heat dissipation. Follow-up sizing stands accurately calibrate outer dimensions to meet tight tolerance requirements, while downstream Turks Head assemblies refine profiles and implement pre-straightening, delivering finished tubes with consistent dimensional uniformity, outstanding straightness and superior comprehensive geometric precision.

Conventional Forming(W Forming)

This design features enhanced maintainability and operational convenience, while effectively improving on-site safety.

High-precision forming stands adopt mechanical shaft expansion for roll shaft connection, ensuring outstanding dimensional accuracy of pipe diameters.

It delivers superior performance and maximizes production throughput. This solution not only boosts production speed, but also reduces equipment wear and tear to extend the service life of the machinery.

Flexible Forming(FF/FFX)

It not only cuts down roll replacement time significantly, but also reduces roller costs by 40–60%.

Rollers are compatible for producing round and square tubes within a certain size range on the same production line, eliminating frequent replacements for different specifications.

By automating multiple procedures in the tube forming process, FF/FFX technology minimizes manual work, effectively lowering labor costs and reducing human error.

Direct Forming(DFT)

It delivers excellent flexibility. Tube dimensions within the mill’s size range can be adjusted without roll replacement.

Full automation of line operation and roll adjustment cuts labor requirements, boosts productivity, and lowers inventory and associated costs.

Equipped with a built-in recipe database and mobile touch screen, the system enables one-click automatic adjustment of roll angles and positions during product changeovers.

Quick Change System

During product changeover, the entire shaft assembly can be lifted from the horizontal stand. Replacement takes only minutes rather than hours.

The universal shaft is automatically engaged and disengaged by hydraulic cylinders. This allows rolls to be prepared, replaced and adjusted offline without halting production.

While offline roll preparation is underway, a pre-assembled spare shaft assembly can be mounted onto the horizontal stand to finish the changeover. This quick-change system drastically cuts machine downtime.
