From April 22nd to 24th, 2026, the 29th China International Trenchless Technology Seminar & Exhibition (ITTC 2026) grandly took place at the National Exhibition and Convention Center (Tianjin). Covering an exhibition area of 20,000 square meters, this event featured 124 carefully selected industry enterprises showcasing their latest products and technologies, attracting thousands of professional visitors from 26 countries and regions worldwide.
As a leading enterprise in China’s trenchless rehabilitation industry, we made a stunning appearance with its core products, drawing wide attention and in-depth exchanges from numerous domestic and international guests through its robust technological strength.
Pro-liner displayed a world-class ultra-large DN2400 diameter liner on-site, demonstrating our outstanding capabilities in ultra-large-diameter pipeline rehabilitation. In addition, transition liners and waterproof outer films tailored for complex working conditions were also exhibited, expanding application possibilities for diverse project scenarios.
We also presented successful rehabilitation cases completed with customized materials, fully showcasing Pro-liner’s professional expertise in the field of UV-CIPP curing rehabilitation technology.
Throughout the exhibition, Pro-liner’s booth remained crowded with visitors and maintained a vibrant atmosphere. Professional representatives from domestic municipal engineering bureaus, water utility groups and pipeline maintenance institutions came to inquire in detail about product specifications and construction solutions.
Meanwhile, Pro-liner attracted a large number of international professional buyers and industry experts for on-site communication. Leveraging extensive project experience and professional technical explanations, the Pro-liner technical team conducted in-depth discussions with guests on the application prospects of UV-CIPP pipeline rehabilitation technology across various industries and complex scenarios.
During the special keynote session on pipeline renewal, Senior Engineer Wang Danghui, Technical Director of the Electromechanical R&D Team at Pro-liner’s R&D Center, was invited to deliver a themed report titled “Development and Application of UV-CIPP Curing Equipment for Potable Water Pipes”, sharing the company’s latest R&D achievements in UV-curing rehabilitation equipment for potable water pipes.
Notably, the UV-CIPP curing system designed for potable water pipe rehabilitation efficiently addresses key challenges in trenchless water pipeline renewal. With groundbreaking technological innovation, it was awarded the 2025 Outstanding Trenchless Product Award. Following the 2024 Outstanding Product Award for its culvert rehabilitation liner, this honor marks Pro-liner’s third consecutive win of this prestigious industry award.
