As a specialized manufacturer with over a decade of experience in pipeline rehabilitation equipment, Qingdao Yongke Machinery Co., Ltd. proudly presents our high-performance CIPP Felt Liner Line. This product is engineered to be the reliable backbone of trenchless sewer repair projects, offering a durable, permeable, and precisely manufactured felt tube that serves as the structural matrix for the Cured-In-Place-Pipe (CIPP) process. Our liners are designed to transform into a strong, seamless, and jointless new pipe inside the old one, providing municipalities and contractors with a cost-effective, environmentally friendly, and long-lasting solution for aging sewer infrastructure.
Core Product Characteristics & Technical Advantages:
- Premium Material Construction: Our liners are manufactured from high-quality polyester felt or composite fabrics. The material is selected for its excellent tensile strength, consistent permeability, and ability to fully saturate with resin, ensuring a uniform and robust final pipe wall.
- Precision Engineering for Consistent Performance: Every liner is produced under strict quality control to ensure dimensional accuracy, uniform thickness, and absence of defects. This consistency is critical for achieving predictable resin uptake and final mechanical properties in the rehabilitated pipe.
-
Customizable Design for Project Fit: We understand that every sewer rehabilitation project is unique. Therefore, our liner line is highly customizable:
Parameter Customization Options Diameter Available from 100mm (4 inches) to 1500mm (60 inches) and beyond upon request. Length Can be supplied in standard roll lengths or custom lengths to match specific project pull-through distances. Thickness & Weight Various felt weights and thicknesses are offered to match the required final wall thickness and structural class of the new pipe. Reinforcement Optional layers of fiber reinforcement can be integrated for projects requiring higher stiffness or tensile strength. - Optimized for Resin Saturation: The fabric's permeability is engineered to allow rapid and complete impregnation with thermosetting resins (epoxy or polyurethane), minimizing dry spots and ensuring a homogeneous composite structure after curing.
- Seamless & Jointless Final Product: The liner acts as a continuous tube. After installation and curing, it forms a new, jointless pipe within the host pipe, eliminating points of weakness and preventing root intrusion or joint leakage.
-
Key Benefits for Our Clients:
- Reduced Project Cost & Time: The trenchless CIPP method, facilitated by our liner, drastically cuts costs compared to open-cut replacement by avoiding excavation, traffic disruption, and surface restoration.
- Extended Infrastructure Lifespan: Rehabilitation with our liner can extend the service life of sewers by 50+ years, providing a long-term return on investment.
- Environmental Sustainability: The process minimizes disturbance to the surrounding environment and community, reduces material waste, and preserves existing infrastructure.
- Versatility & Reliability: Suitable for rehabilitating pipes of various shapes (circular, egg-shaped) and materials (concrete, clay, cast iron, PVC), our liners provide a reliable solution for diverse municipal challenges.

Frequently Asked Questions (FAQ):
-
Q: What is the primary function of this felt liner in the CIPP process?
A: The felt liner serves as the carrier fabric or "sock" that is impregnated with liquid resin. It is pulled into the damaged pipe and then cured (usually with hot water or steam) to form a rigid, structural composite pipe lining inside the old host pipe. -
Q: How do I determine the correct diameter and thickness for my project?
A: The liner diameter is typically chosen based on the internal diameter of the host pipe to be rehabilitated. The thickness (felt weight) is selected based on the desired final wall thickness and structural class required for the new lining. Our technical team can assist you with these calculations based on your project specifications. -
Q: Is the liner compatible with all types of resins?
A: Our standard polyester felt liners are designed for compatibility with common thermosetting resins used in CIPP, such as epoxy and polyurethane. We recommend confirming resin compatibility for specific chemical formulations. -
Q: What is the typical delivery lead time for custom-sized liners?
A: Lead times vary based on the order size and customization requirements. For standard sizes, shipment can be arranged promptly. For large custom orders, we provide a production schedule upon receipt of your detailed specifications. Our efficient logistics from Qingdao port help ensure timely delivery. -
Q: How is the liner packaged and shipped to prevent damage?
A: The liner is carefully rolled onto sturdy cores to maintain its shape and integrity. It is then wrapped in protective packaging to shield it from moisture, dust, and physical damage during transportation. -
Q: Can you provide liner samples for testing before a large order?
A: Yes, we can arrange for samples of our standard felt materials to be sent for your evaluation and compatibility testing with your resin system. Please contact us to request samples. -
Q: Does the liner require any special storage conditions on-site?
A: The liner should be stored in a dry, clean environment away from direct sunlight and extreme temperatures until it is ready for impregnation. This preserves its material properties. -
Q: What support do you offer after the product is delivered?
A> We provide product documentation and are available for technical consultation regarding the proper use and handling of our liner. Our experience in supplying global markets means we understand the practical challenges of projects and can offer relevant advice.
