Trenchless Rehabilitation of Fluid Transfer Lines
Industrial pipeline rehabilitation is made easier with Mandals Tubeman, which is designed for trenchless rehabilitation of drain water pipes, sewage pipes, as well as gas pipes. Mandals Tubeman is ensuring a “stand-alone” pipe rehabilitation solution, giving a continual and safe fluid supply even if the host pipe should fragment or break. Its integrity on high-quality standards and easy installation method opens up a wide range of pipe rehabilitation application fields. It has excellent hydrolysis and microbiological resistance in water-based environments, even at elevated temperatures.
A Smarter Way
Mandals Tubeman has been specifically designed for the trenchless rehabilitation of industrial pipelines that transport hydrocarbons, such as fuels, gasoline, natural gas, oil, and other non-aggressive liquids and gases.
Cost-Efficient
Great Adhesion and Tensile Strength
Safe Installation
Long Lifetime and Low Maintenance
Easy to Deploy and Store
Less Impact on the Environment
High Working Pressure
High Quality Materials
Explore Mandals Tubeman
Mandals Tubeman offers a long-lasting, cost-effective, high-quality stand-alone solution to rehabilitating leaking pipes.
Mandals Tubeman
With Mandals Tubeman we offer a more sustainable solution for the rehabilitation of old pipelines with minimal disruption to traffic, pedestrians, and the environment in general, with an improved CO2 footprint and HSE performance. The hose is flexible in terms of the diameter variation of the original pipe, effortlessly passing sharp bends even at longer lengths.
Production and Design
Mandals Tubeman L is a semi-structural, stand-alone liner that will ensure continual fluid supply even if the host pipe should break. In other words, the liner will handle all the pressure, while the pipe structure will help it not collapse.
The “extrusion through the weave” production technology gives excellent bonding between the cover and lining and firmly encapsulates the circular woven polyester reinforcement.
It consists of a thermoplastic polyurethane (TPU) with excellent wear & tear properties, outstanding hydrolysis resistance, and resistance against microbiological attack.
The liner is leak-proof, tested, packed, and delivered in a “U” -shape.
Installation Process
Before installation, a regular cleaning procedure is required for the host pipe and the condition is controlled by CCTV inspection.
The liner is pulled through the host pipe using a wire winch, e.g. and can be installed in pipelines with bends and pipe diameter variations. The number of bends and sharpness (bend angle and R/D – ratio) will impact the installation’s maximum section lengths.
No steaming or other means of curing is required. Operating at maximum working pressure, the outer diameter of the liner will be about 10mm less than the inner diameter of the rehabilitated pipe.
Product Specifications
Primary Uses & Applications
- Safe trenchless rehabilitation of industrial pipelines
Color Options
- Black (standard)
Lengths and Diameters – Tubeman L
For Tubeman L we offer a range of diameters and lengths for this liner, depending on the nominal pipe diameter. The diameters range from DN25mm to DN350mm.
- DN25-DN150 can be delivered in lengths up to 600m
- DN200-DN350 can be delivered in lengths up to 400m
Lengths and Diameters – Tubeman M
For Tubeman M we offer a range of diameters and lengths for this liner, depending on the nominal pipe diameter. The diameters range from DN150mm to DN350mm.
- DN150-DN350 can be delivered in lengths up to 400m
Section Lengths Will Depend On
- Hose Diameter: Large dim = > Shorter lengths. Secondly, higher friction and drum space.
- Number of bends: More bend => Higher friction => Higher pull-force.
- Bend angle and R/D ratio: Sharp bends (critical low R/D ratio) => Higher friction and greater risk of damage to the hose during Pull-in. Can be dampened with good lubrication (silicone oil/cooking oil etc) on the hose. Increased risk of “kinking” of the hose within the bend and reduced flow.
Operating Temperature
The Maximum recommended operating temperature is +30°C (86°F), but the actual fluid transferred will determine whether that temperature is appropriate.
Lifetime Expectancy
The estimated Service lifetime will depend on several factors. Proper pre-cleaning of the host pipe, CCTV inspection, and checking for sharp spikes are vital. Of no less importance is the chemical resistance of the TPU polymer to the actual fluid transferred, and the operating temperature.
Chemicals and pH Range
The polymer in Tubeman L & M is resistant to weak acid or base solutions in the pH range of 4-9, depending on operational temperature.
There may be other and special chemical-resistant polymers available on a project-by-project basis.
