Material Selection Considerations for Efficient Trenchless Pipe Lining Fabrication


The growing urban population and aging infrastructures globally have caused an unprecedented growth for trenchless pipe lining solutions. More urban centers now prefer pipe rehabilitation methods that cause minimum disturbance to the day-to-day activities in the area. 

CIPP (Cured in Place Pipe)   is the most common no-dig solution currently used in the market and their applications have evolved from laterals and mainlines to other pipelines as well. CIPPs can handle most curves, minimize the loss of pipe bore, and can be typically installed with the least amount of damage to the road and adjoining areas.


The importance of Involving an experienced manufacturer

 Successful implementation of a CIPP solution depends on several factors related to the material combination, production environment, and the installation process. Having the right manufacturing partner for your CIPP applications is more important than you think. From selecting the correct raw material for your application, which is often the first step for success, to ensuring the optimum specifications. Involving an experienced manufacturer can help make the job easier and potentially reduce your overall costs.


4 key areas to focus on when selecting CIPP fabric



1- High level of Customization required per application
As a result of many advancements in CIPP solutions, the typical off the shelf solutions have expanded to many custom products, with more expected.. The number of variables are many from curing methods, pipe diameter, outside temperature, area, and the number of bends/curves are some of the main factors that determine the suitable specification for any job. When creating a product, you need to ensure that your selected coated  felt supplier can deliver specialized solutions of the optimum thickness, weight, and other properties.


2- Material compatibility requirements per installation procedure
Building on the previous issue, even the installation procedures vary according to the job. Installers usually rely on different resins and curing methods to warrant the best performance of their trenchless pipe lining solution. Before material selection, you need to ensure that it is compatible with both, the installation method and the application requirements. Your manufacturing partner can help you choose the best solution according to your needs.


3- Prevent excessive waste during the fabrication
During CIPP applications you’ll want to prevent excessive waste during the fabrication. As a business, you need to find the perfect balance processing efficiency, performance, and the associated costs. Once again, your material supplier is the perfect entity to help you with this issue.


4 – Take advantage of technological advancements
Historically there have been limited sources for CIPP products. today CIPP installers have the option of direct sourcing from a material manufacturer. Things are different today. Advancements in CIPP technology have simplified many processes. Thanks to the latest automated equipment, many large installers are now capable of fabricating pipe products and are innovating with coated felt manufacturers to maximize their profitability.


Find the right manufacturing partner for your CIPP applications

The Essentials of Manufacturing CIPP Pipe Lining for Improved Performance

CIPP solutions were first introduced in the 70s. Since then, they have proven their worth in various fields across the globe. manufacturing CIPP pipe lining technology had many limitations at first, but it improved with time. CIPP solutions have advanced considerably in the last few years as new and improved curing methods have been established. Today, CIPPs are much more durable, safer, and are versatile enough for a large variety of industrial applications. 

Because the variety in the Cured in Place Pipe (CIPP) market is quite significant, manufacturing CIPP pipe lining requires a lot of considerations and a wide range of manufacturing solutions.  A manufacturing solution must be able to offer diversity, large fabric handling capacity, multiple seam configuration options, and consistent quality output.  


Manufacturing Factors to Consider:

 – The number of layers
 – Seam types
 – Diameter ranges
 – Made to order options
 – Packaging for ease of shipment
 – Absorption of resin at the seam
 – Ability to weld multiple rolls of the same or different thickness simultaneously
 – The positioning of each seam within the different layers
 – The ability to invert without damaging the integrity of the resin at the seam
 – The ability to sew or weld multiple fabrics including Non-wovens or Felt liners that may be coated with polypropylene(TPO), polyurethane(TPU), polyethylene, or PVC


Seam Types:

– Hot-air welded overlap seams
– Hot-air welded butt seams
– Sewn seams (Many Variations)
– Sewn seams with welded tape on top
– Sewn seams with extrusion applied on top

The principles for completing finished CIPP products 

All automated systems have the same basic principles in order to complete finished CIPP products. Required in all systems is a heavy-duty unwind to meet the demands of cured-in-place materials and fabrics. A heavy-duty puller to move the product through the system. A guiding and web control closed-looped system to ensure proper tension and alignment of the product into the sewing and welding areas. It may be required to have more than one type of seam bonding (weld, sew extrude) system or multiple combinations. Lastly, it is important to have a good consistent, and quality output system for a product that can be shipped to a customer on-demand or for stock. 


The Fabric Manufacturing Process can Determine the Quality and Performance of Your CIPP Solution

Cured-in-place-pipes are certainly a convenient and durable choice of pipe repairs and other applications. However, they undergo a lot of processes before they are ready for deployment in the field. The manufacturing process often determines the quality and other essential performance characteristics of any CIPP solution. You must take extra care that all the technical characteristics, intended applications, seam type, absorption rate, and numerous other factors are being considered. This will ensure consistent and long-lasting performance for your CIPP solution in any location.
