CISDI’s designs for Dalipal Pipe Company are hailed as industry breakthroughs in China

Dalipal Pipe Company’s new Piercer Mill has passed its hot commissioning on schedule.

The design, manufacture and commissioning of this critical piece of equipment, for the plant’s Φ159mm seamless tube rolling line, was a first for CISDI.

So too was CISDI’s creation of two other crucial sections - a three-roll multi-stand rolling mill and a stretch reducer milI, which both passed a smooth hot commissioning two weeks later.

The success of these three sections enabled the entire tube mill to go into operation. It is now ramping up production capacity to hit a target of 300,000 tonnes a year.

CSIDI’s innovative designs are seen as a substantial breakthrough in seamless tube mill expertise. The three new items of equipment determine the final tube’s specification and quality, which Chinese manufacturers have long found problematic.

Mostly imported, they are now being supplied by a competent Chinese engineering company.
