Quick-Lock PRESSURE PIPE (LD + HD)

The system for rehabilitating
pressurized pipelines

Application: pressurized pipelines

The Quick-Lock PRESSURE PIPE sleeve (LD + HD) was developed to rehabilitate damage in pipes with a nominal diameter of DN 150–800 / 6–32” and internal pressures of -0.9 to +50 bar / -13.05 to 725.19 psi. LD stands for “low duty” and HD means “high duty”.

Quick-Lock PRESSURE PIPE (LD + HD) system description

The Quick-Lock PRESSURE PIPE sleeve (LD + HD) serves to rehabilitate damage in pressurized pipelines with a nominal diameter between DN 150 and DN 800 / 6” and 32”. The Quick-Lock PRESSURE PIPE sleeve (LD) was designed to rehabilitate pressurized pipelines that are subject to infrequent, low-intensity pressure surges.

It is suitable for internal pressures from -0.9 to +50 bar / -13.05 to +725.19 psi.

The Quick-Lock PRESSURE PIPE sleeve (HD) was developed to permanently withstand high-frequency, high-intensity pressure surges. In the course of testing, the sleeve was able to endure more than 2 million pressure load cycles between -0.9 and +10 bar / -13.05 and +145.04 psi, thanks to its advanced locking mechanism, thicker material, and special alloy.

This is a milestone never before reached in the sleeve technology sector.

When using a Quick-Lock sleeve in a pressurized pipeline, the pressure resistance can only be guaranteed when the sleeve is used in combination with a protector shield.

The protector shield stops the seal from creeping into any gaps or cracks in the pipe wall. This prevents the seal from being damaged.

How it works

  • The Quick-Lock PRESSURE PIPE sleeve (LD + HD) was developed specifically for use in pressurized pipelines.
  • For internal pressures from -0.9 to +50 bar / -13.05 to +725.19 psi.
  • The Quick-Lock PRESSURE PIPE sleeve (LD) was designed to rehabilitate pressurized pipelines that are subject to infrequent, low-intensity pressure surges.
  • The Quick-Lock PRESSURE PIPE sleeve (HD) was developed to ensure long-term resistance in the case of high-frequency, high-intensity pressure surges.

Advantages of the system

Scope of application

  • Potable water pipelines
  • Pressurized wastewater pipelines
  • Industrial applications
  • Borehole rehabilitation

Specifications

Materials

The materials used in potable water applications, pressurized wastewater pipes, industrial rehabilitation, and for sealing boreholes are 316L stainless steel and silicone seals.

316L stainless steel is extremely durable in municipal wastewater applications.

In the case of seawater applications, 904L stainless steel is used in combination with the silicone seals.
