Advanced Repair Technology for Plastic and Metal Pipes, Tanks and Industrial Equipment
The Tech Patch Repair System (TPRS™) is an advanced industrial repair technology developed by Tech-Bond Global to restore damaged plastic and metal pipes, tanks, and industrial equipment without the substantial expense, downtime, and operational disruption associated with replacement.
Built around Tech-Bond’s patented Polymer Bonding Process™ and reinforced with PTFE-coated E-glass fabric, TPRS™ provides durable, conformable repairs engineered for demanding industrial environments. Independent testing, including HDPE pressure testing, salt spray exposure, and accelerated aging evaluations, has demonstrated exceptional performance under the conditions tested.
The economic advantages can be substantial. By repairing localized damage rather than replacing entire pipe sections or tanks, industrial operators can reduce material costs, labor requirements, excavation, equipment downtime, and production interruptions. TPRS™ transforms pipe and tank repair from a temporary maintenance response into a potentially long-term asset preservation strategy.
The Global Cost of Pipe Failure and Replacement
The chart and graph below shows the estimated economic impact of pipe maintenance and replacement across key industries, now and over the next five years.
The Growing Economic Burden of Aging Infrastructure
Across the world, aging pipelines and storage systems create enormous financial challenges for water and wastewater utilities, mining operations, energy producers, and industrial manufacturers. Pipe deterioration, corrosion, leaks, and structural failures increase maintenance expenditures, interrupt operations, and force organizations to replace infrastructure that might otherwise remain serviceable.
The economic consequences extend far beyond the immediate cost of repairing or replacing a damaged pipe.
1. Aging Infrastructure — A Growing Financial Burden
When pipelines fail, organizations face expenses that extend well beyond replacement materials. Excavation, specialized labor, equipment, production shutdowns, environmental remediation, and service interruptions can substantially increase the total cost of failure.
For many industrial operators, the greatest expense is not the damaged pipe itself, but the downtime required to replace it.
2. The Economic Consequences of Pipe Failure
Pipe failures affect virtually every major industrial sector:
Water and Wastewater: Leaks, service interruptions, emergency repairs, and increasing infrastructure maintenance costs.
Mining: Interruptions to slurry transportation, processing operations, and water management systems.
Oil and Gas: Pipeline failures, environmental exposure, operational shutdowns, and regulatory concerns.
Manufacturing: Production disruptions, equipment damage, and unplanned maintenance expenditures.
These consequences make effective infrastructure maintenance a financial and operational priority.
3. Repair Rather Than Replace — A Different Economic Approach
Conventional infrastructure maintenance often involves removing and replacing damaged sections of pipes or tanks. While replacement is sometimes necessary, localized damage does not always justify replacing an otherwise serviceable component.
Advanced repair technologies create an opportunity to preserve existing infrastructure, reduce material consumption, and minimize operational disruption.
The Tech Patch Repair System (TPRS™) was developed specifically to address this opportunity.
Using Tech-Bond’s patented Polymer Bonding Process™ and PTFE-coated E-glass reinforcement, TPRS™ provides an alternative for repairing suitable localized damage in plastic and metal pipes and tanks.
4. The Economic Opportunity for TPRS™
For industrial operators, the potential benefits of successful localized repairs include:
Reduced replacement material and installation costs.
Less excavation, cutting, welding, and equipment removal.
Shorter maintenance shutdowns and reduced production losses.
Extended useful life of serviceable infrastructure.
Reduced material waste and unnecessary replacement.
Actual savings depend on the damage, operating conditions, accessibility, and suitability of the repair.
The Bottom Line: Repair Rather Than Replace
The future of industrial infrastructure maintenance will increasingly depend on technologies that preserve existing assets rather than automatically replacing them.
TPRS™ offers industrial operators a new approach: repair suitable localized damage, reduce unnecessary replacement costs, minimize downtime, and extend infrastructure service life.
Repair Rather Than Replace.
How the Tech Patch Repair System (TPRS™) Works — The Technology Behind the Repair
An Engineered Approach to Industrial Pipe and Tank Repair
The Tech Patch Repair System (TPRS™) combines several complementary technologies developed and refined by Tech-Bond Global. At the center of the system is Tech-Bond’s patented Polymer Bonding Process™, supported by Molecular Integration™ (MI), specialized industrial Bonding Agents, and PTFE-coated E-glass reinforcing fabric.
Together, these technologies address one of the most important challenges in industrial repair: creating a durable interface between the damaged substrate and the repair material.
Unlike conventional repairs that depend primarily on mechanical restraint or the adhesion of a surface coating, TPRS™ is engineered to create a strong, integrated repair assembly that conforms to the original component.
1. The Polymer Bonding Process™ — The Foundation of TPRS™
The patented Polymer Bonding Process™ is the foundational technology behind Tech-Bond’s ability to bond materials traditionally considered difficult to join.
Many industrial polymers, including polyethylene (PE), high-density polyethylene (HDPE), polypropylene (PP), and polytetrafluoroethylene (PTFE), present significant bonding challenges because of their surface chemistry and low surface energy.
Conventional industrial adhesives often struggle to establish reliable adhesion to these materials without specialized surface treatment.
Tech-Bond’s Polymer Bonding Process™ addresses this challenge through a controlled sequence of surface preparation, chemical treatment, activation, industrial Bonding Agent application, and curing.
The Process is designed to prepare the substrate and promote a strong bonding interface, allowing Tech-Bond’s industrial Bonding Agents to join materials that conventional adhesive systems frequently cannot bond effectively.
The breakthrough is not simply a stronger industrial adhesive. It is a process designed to make difficult-to-bond materials bondable.
2. Molecular Integration™ (MI) — Engineering the Interface
Molecular Integration™ builds upon the Polymer Bonding Process™ by focusing on the interface where two materials are joined.
In conventional bonding, the interface is frequently the weakest point in the assembly. Differences in surface chemistry, thermal expansion, flexibility, and environmental exposure can contribute to premature failure.
MI represents Tech-Bond’s approach to developing a more integrated interface between dissimilar materials through specialized surface preparation, chemical activation, and industrial Bonding Agents.
The objective is to promote strong molecular-level interactions and durable bonding performance while accommodating the physical characteristics of the joined materials.
Tech-Bond’s testing has demonstrated strong adhesion and resistance to separation in several material combinations, including difficult-to-bond polymers.
MI changes the engineering question from “Which adhesive will stick?” to “How do we engineer the interface so the materials remain joined?”
3. PTFE-Coated E-Glass Fabric — High-Performance Structural Reinforcement
An essential component of TPRS™ is PTFE-coated E-glass fabric, a composite material combining the mechanical strength of E-glass fibers with the chemical and environmental resistance associated with PTFE.
E-glass fabric provides tensile strength, dimensional stability, and reinforcement. The PTFE coating contributes chemical resistance, low moisture absorption, and environmental durability.
These characteristics make PTFE-coated E-glass fabric an attractive reinforcement material for industrial pipe and tank repairs.
Key Material Advantages
High Tensile Strength: E-glass fibers provide reinforcement that helps distribute mechanical loads across the repaired area.
Chemical Resistance: PTFE offers resistance to many chemicals encountered in industrial environments.
Moisture Resistance: The PTFE coating provides a low-wetting surface that helps limit moisture exposure.
Thermal Stability: Both E-glass and PTFE can tolerate temperatures beyond those suitable for many conventional polymer repair materials, although the complete bonded system has its own operating limits.
Flexibility and Conformability: The fabric can conform to curved pipe surfaces, tanks, and irregular geometries.
Corrosion Resistance: Unlike metallic reinforcement, PTFE-coated E-glass fabric does not undergo conventional metallic corrosion.
The engineering advantage comes from combining this reinforcement with Tech-Bond’s Polymer Bonding Process™.
Materials that are traditionally difficult to bond, including PTFE, can become functional components of an integrated repair system.
The reinforcing fabric supplies mechanical strength. The Polymer Bonding Process™ enables the critical bond between the reinforcement and the substrate.
4. Tech-Bond Industrial Bonding Agents — Creating the Bonded Assembly
Tech-Bond’s specialized industrial Bonding Agents work in conjunction with the Polymer Bonding Process™ to establish the interface between the repair material and the damaged substrate.
Rather than relying on thick layers of conventional epoxy resin, TPRS™ uses a controlled bonding process to join the reinforcement directly to the prepared surface.
The selection and application of the Bonding Agent depend on the substrate, repair geometry, and operating requirements.
When properly applied and cured, the resulting bonded assembly is designed to transfer loads between the substrate and the reinforcing fabric while maintaining adhesion under the intended service conditions.
The industrial Bonding Agent is an essential component of the system, but it is the combination of the Process, the Bonding Agent, and the reinforcement that makes TPRS™ distinctive.
5. Thermal Conformance — Adapting the Repair to the Substrate
Industrial pipes and tanks are rarely perfectly flat. They may have curved surfaces, seams, irregular contours, and localized damage.
Thermal Conformance is Tech-Bond’s approach to using controlled warmth, where appropriate, to assist the bonding and conforming process.
By helping the reinforcing material maintain close contact with the prepared substrate, Thermal Conformance supports consistent application across complex geometries.
The objective is to minimize gaps, promote uniform contact, and support development of the bonded interface.
Application temperatures and procedures must be selected according to the substrate, Bonding Agent, and repair conditions.
6. Poly Fill™, Silica Fill™, and Poly Shield™ — Completing the Repair System
Not all pipe and tank damage consists of a simple crack. Some repairs involve holes, missing material, surface deterioration, or irregular damage that must be addressed before reinforcement is applied.
Tech-Bond has developed complementary materials to support these applications.
Poly Fill™ is used where compatible polymer-oriented filling and surface restoration are required before applying reinforcement.
Silica Fill™ provides a mineral-based filling option for suitable repair applications, helping restore damaged areas and create a more consistent repair surface.
Poly Shield™ is a protective coating system intended to provide an additional environmental barrier over selected repairs.
Together, these materials allow TPRS™ to address a broader range of repair geometries than a simple surface patch alone.
7. A Complete Engineered Repair System
The performance of TPRS™ depends on the interaction of its components:
The Polymer Bonding Process™ prepares difficult-to-bond substrates.
Molecular Integration™ focuses on engineering a durable interface.
Industrial Bonding Agents create the bonded connection.
PTFE-coated E-glass fabric provides mechanical reinforcement.
Thermal Conformance supports close contact and conformity where appropriate.
Poly Fill™, Silica Fill™, and Poly Shield™ address selected filling and environmental protection requirements.
Each component serves a specific purpose. Together, they form a repair system intended to restore localized damage while preserving the surrounding infrastructure.
The Result: Repair Rather Than Replace
TPRS™ represents a different approach to industrial maintenance: rather than automatically replacing a damaged pipe or tank, evaluate whether the existing structure can be restored through an engineered bonded repair.
For suitable applications, the result can be reduced downtime, lower replacement costs, less material waste, and extended infrastructure service life.
Tech-Bond Global — Bond What Others Cannot. Repair What Others Replace.
But HDPE pipe cannot be repaired!
That was then, this is now!
For years, repairing damaged HDPE pipes has presented a major challenge. Conventional industrial adhesives struggle to bond polyethylene, leaving welding, mechanical fittings, or complete pipe replacement as the traditional solutions.
Tech-Bond Global has changed what’s possible with the Tech Patch Repair System (TPRS™).
Built around Tech-Bond’s patented Polymer Bonding Process™ and reinforced with PTFE-coated E-glass fabric, TPRS™ provides an innovative method for repairing cracks, holes, and localized damage in HDPE pipes without cutting out and replacing entire pipe sections.
Independent pressure testing conducted for Borouge demonstrated the remarkable potential of this technology. A repaired 4-inch SDR11 HDPE pipe withstood approximately 1,800 psi during burst testing, with failure occurring outside the repaired area.
For water and wastewater utilities, mining operations, and industrial facilities, TPRS™ offers an alternative to conventional replacement methods—potentially reducing downtime, excavation, labor, and material costs.
HDPE pipe repair is no longer limited to traditional methods. TPRS™ makes a new approach possible.
Repair Rather Than Replace.
The Borouge HDPE Pipe Test — 1,800 PSI!
At 1,800 PSI, The Pipe Failed. The TPRS™ Repair Did Not.
In independent testing conducted by Borouge, a 4-inch HDPE SDR11 pipe containing a deliberately introduced notch was repaired using Tech-Bond’s Tech Patch Repair System™ (TPRS™) and subjected to increasing internal pressure. The pipe withstood pressure up to 1,800 PSI before bursting outside the repaired area. Remarkably, the TPRS™ repair remained intact while the surrounding HDPE pipe failed. This result demonstrates the exceptional strength of the repaired section and the ability of TPRS™ to withstand extreme internal pressure. The significance is clear: the pipe failed, but the Tech-Bond repair did not.
