SL600 Corrugated Pipe Line Commissioned in Central Asia for Gas Distribution Infrastructure

SL600 Corrugated Pipe Line Commissioned in Central Asia for Gas Distribution Infrastructure

Project Context

A regional infrastructure authority launched a major initiative to expand gas distribution networks. The project required sourcing reliable, high-capacity corrugated HDPE pipe production to meet growing demand from municipal and industrial clients in the region.

A local pipe manufacturer identified the need for a dedicated production line capable of delivering 1,200+ linear meters of corrugated pipe per shift, maintaining consistent quality and durability in extreme temperature conditions.

Why the SL600

The operations team evaluated three production line suppliers, focusing on:

  • Output capacity: 1,200+ m/shift
  • Durability in continental climates (−40°C to +50°C)
  • Spare parts availability in the region
  • Training and technical support

After evaluating production line options, the team selected the SL600 for its proven reliability in similar climates, modular design, and strong regional support network.

The Order

Contract signed in March 2024 for one SL600 unit with optional mill extension. Total investment: €185,000. The manufacturer committed to annual capacity of 100,000+ linear meters of corrugated pipe for municipal and industrial applications.

Delivery & Installation

Suba shipped the unit in July 2024. Installation took 3 weeks, with two Suba technicians on-site for machine setup and operator training. The local team completed a 2-week intensive certification course.

Results

The line has been in continuous operation since Q3 2024, producing 1,250 m/shift of 300–600mm corrugated HDPE pipe. Quality metrics:

The manufacturer has already expanded to a second SL600 unit based on success.

"The Suba SL600 has become the backbone of our operation. We're now supplying municipal authorities across the region and neighboring countries. The machine's reliability and the Suba team's support made this investment one of the best decisions we've made." — Plant Manager
