The importance of material selection by renowned trenchless rehabilitation suppliers JBP Composites S.L.

The choice of materials plays a pivotal role when choosing the TrenchlessTechnology to be applied. The Quick-Lock System, a renowned trenchless rehabilitation solution supplied by JBP Composites S.L., underscores the significance of selecting the right stainless steel and rubber material tailored to the specific characteristics of the pipeline, be it for water, sewage, or other applications.

One of the primary reasons Quick-Lock has gained prominence is its ability to provide an effective and durable solution. The success of this trenchless method, however, is intricately tied to the careful consideration of materials, particularly stainless-steel, and EPDM.
Stainless steel, making the appropriate choice of material.

Stainless steel stands out as the material of choice in Quick-Lock projects due to its
remarkable corrosion resistance, strength, and versatility. The corrosion resistance
is particularly crucial when dealing with water pipelines, where exposure to moisture and various chemicals poses a constant threat to the structural integrity of the rehabilitation system. Quick-Lock’s deployment of high-quality stainless steel ensures resilience against corrosion, minimising deterioration over time.

The diversity of stainless-steel materials available for Quick-Lock applications further enhances its adaptability to various pipeline types. Different grades of stainless steel can be selected based on the specific demands of the rehabilitation project. Whether dealing with potable water pipelines, wastewater systems, or seawater projects, JBP offers a tailored approach through the careful choice of materials.

Beyond corrosion resistance, the strength of stainless steel is a key factor in the longevity of the rehabilitation. Quick-Lock’s use of robust stainless-steel materials provides structural support, leak tightness, with a life expectancy of 50+ years.

The Quick-Lock System can be supplied with:

Stainless steel AISI 316L:

– Composition: Contains 16-18% of chromium, 10-14% of nickel
and 2-3% of molybdenum.
– Common Applications: Widely used in various industries, especially in marine environments and chemical processing.

Known for its excellent corrosion resistance, good formability,
and weldability.

Stainless steel AISI 904L:
– Composition: Contains high amounts of chromium (19-21%),
nickel (24-26%), and molybdenum (4-5%).
– Common Applications: Primarily used in environments with aggressive corrosion conditions, such as cellulose industry, offshore, refineries, seawater technology, hot sulphuric, and phosphoric environment.

Selecting the ideal rubber seal: EPDM, VMQ or NBR EPDM (Ethylene Propylene Diene Monomer), NBR (Nitrile Butadiene Rubber), and VMQ (Vinyl Methyl Silicone) are different types of rubber with different properties, and their suitability for use in wastewater, sea water, or drinking water depends on several factors.

WASTEWATER APPLICATIONS: EPDM is an elastomeric material with a low viscosity. This rubber has several properties, such as:- Excellent resistance to weathering, UV and ozone.
– Good resistance to water, steam and some acids and bases.
– Wide temperature range, typically -50°C to +90°C (long term) or
+150°C (short term)
– Limited resistance to oil and petroleum-based products.
– High resistance to permanent deformation

DRINKING WATER APPLICATIONS: VMQ is a type of silicone rubber composed of silicon, carbon, hydrogen, and oxygen with the following properties:
– Excellent high temperature resistance, typically up to +210°C

Good resistance to weathering, ozone and UV radiation.
– Good electro-insulating properties
– Not resistant to silicone oils and greases, fuel, water vapor above
– Safe for use in contact with drinking water.

When selecting a material for drinking water applications, it is important to ensure that the material complies with relevant health and safety regulations. In addition, compliance with local and international standards, such as NSF/ANSI 61 for potable water system components, provides assurance that the material is suitable for use in contact with potable water.

We always recommend checking with the supplier and manufacturer for specific
certifications and suitability for the intended application.

OIL PIPE APPLICATIONS: NBR is used mainly in applications where the seals are
in constant contact with grease and mineral oil. Its main properties include:

  • Operating temperature ranges from -30°C to +100°C
  • Good to excellent gas and air impermeability
  • Good resistance to oil
  • Not resistant to fuels with high aromatic content (depending on ACN content)

In conclusion, the importance of material selection in Quick-Lock pipeline rehabilitation cannot be overstated. The choice of stainless steel, with its corrosion resistance, adaptability, and strength, ensures that Quick-Lock projects deliver lasting and effective solutions across a spectrum of pipeline applications. Education and training is an important part of the process in understanding materials, their appropriate selection and effective application. As the demand for efficient and sustainable rehabilitation methods grows, the thoughtful consideration of materials will continue to be a cornerstone in achieving successful and long-lasting pipeline restoration.
