From flat strip to finished tube

Every YH line follows the same five stations. What changes between projects is the roller profile at each one, and that is what we machine in-house.

  1. ST-01

    Uncoil & level

    Coil is uncoiled, levelled and joined strip to strip, so the line keeps running between coils.

  2. ST-02

    Breakdown

    First forming passes bend the strip edges. The roller profile here sets edge stress for the whole line.

  3. ST-03

    Fin pass

    Fin-pass rollers close the strip into an open round and guide the seam to the weld point.

  4. ST-04

    Welding

    TIG, plasma, laser or high frequency closes the seam. The route follows grade and wall thickness.

  5. ST-05

    Size & cut

    Sizing rolls set final diameter and roundness, then the saw cuts to length.

Self-machined tooling & assembled lines

ManufacturingStrengths

YH runs its own CNC machining and assembly workshops in Foshan, Guangdong. In-house: 7 mill series with 47 models, laser and HF welding moulds from Φ5 to 711 mm, every line assembled and run on your pipe spec before dispatch, exported to 50+ countries.

CNC machining workshop

Roller profiles, shafts and moulds are machined in-house: the pass design stays with the machine builder and quality is controlled at source.
