5 Factors to Consider When Choosing A Machine to Weld Your CIPP Liner

March 15, 2021

A cured-in-place pipe (CIPP) is a trenchless rehabilitation method used to repair existing pipelines. It is a jointless, seamless, pipe lining within an existing pipe. The process of CIPP involves inserting and running lining into a pre-existing pipe that is the subject of repair. CIPP linings use a thicker, heavier, resin impregnated liner, such as polyester or fiberglass cloth, that cure within the damaged pipe to a hard, structural finish, essentially creating a pipe within a pipe.

The 5 Factors to Consider When Choosing the Right Machine to Weld Your CIPP Liner.

Manufacturing cured in place pipeline (CIPP) liner requires many considerations and a wide range of manufacturing solutions. Because of significant market variability, manufacturers and material suppliers must be able to offer product diversity and consistent quality output.



When designing your custom machine, the important factors to consider are:


Factor 1. Know the automated systems required to produce your CIPP products

  • Unwind
    • A heavy-duty unwind is needed to meet the demands of CIPP.
  • Heavy duty puller
    • To move your product through the system.
  • A guiding & web control closed looped system
    • This will ensure proper tension and alignment of the product into the sewing and welding areas.
  • Seam bonding system
    • It may be required to have more than one type of seam bonding system to weld, sew and/or extrude or multiple combinations.
  • Output system
    • A consistent and quality output system for your outflow.

 Factor 2. Know your fabric options

  • Non-wovens
  • Felt Liners
  • Coated with polypropylene (TPO), polyurethane (TPU), polyethylene or PVC 

 Factor 3. Know your seam options

Factor 4. Know your end-product considerations

  • Diameter ranges
  • Ability to weld multiple rolls of same or different thickness
  • Positioning of each seam within the different layers
  • Ability to invert - without damaging the integrity of the resin at the seam
  • Absorption of resin at the seam 

Factor 5. Know your capabilities

  • Make to order
    • Greater flexibility for customization
    • Reduce risk of inefficiency
    • Minimize waste
  • Make to stock
    • Insurance against increased demand
    • Planning for seasonal changes
    • Guarding against price increases
    • Accessing discounts
  • Packaging
    • Visual appeal
    • For ease of shipment
    • Protection of product
  • Shipping
    • Cost
      • Dimensional weight
      • Custom duty, tariffs or taxes
      • Surcharges
      • Insurance
    • Destination
      • Shipment speed
      • Target destination
