Founded in 2015, Anhui Pro-liner Pipeline Repair Technology Co.,Ltd. is a national specialized, sophisticated, distinctive, and innovative "Little Giant" enterprise as well as a high-tech enterprise. Focused on the R&D, production and sales of UV-CIPP (Ultraviolet Cured-In-Place Pipe) liners and UV curing systems, we are one of the first enterprises to achieve industrial mass production of UV-CIPP liners in China. Meanwhile, we have obtained ISO international standard certification, CE certification, TÜVRheinland^® and WRc Approved^® certification, which not only validate the standardization of our production and management systems, but also confirm that our products meet the core quality and compliance requirements of the international market, providing reliable product quality assurance to customers worldwide.

Currently, our annual production capacity reaches 18,000 tons for UV-CIPP liners and 60 units for UV curing systems. With stable quality and technological strength, our products have been exported to many countries and regions worldwide, with a cumulative delivery of over 3,000 kilometers of liners, winning high trust from customers both domestically and internationally. Our solutions are widely applied in water environment treatment, urban organic renewal, municipal pipe rehabilitation and major municipal emergency rescue projects, providing solid support for the long-term operation of urban infrastructure.

Our UV-CIPP liners for sewage pipe have taken the lead in overcoming technical difficulties of large diameters (DN1800, DN2000, DN2200, DN2400) and wall thickness (19mm, 22mm), filling the gap in the domestic industry; our UV-CIPP liners for portable water pipe have obtained the drinking water hygiene safety license issued by the National Health Commission, fully ensuring the safety of domestic water supply for people's livelihood.Meanwhile, we are committed to customized services — relying on our professional R&D and technical team, we can accurately grasp customers' actual needs and tailor the most suitable integrated solutions.

At Pro-liner, sustainability is embedded in every link of our UV-CIPP trenchless rehabilitation technology — product R&D, on-site construction and full-life-cycle infrastructure management. We deliver low-carbon, resource-saving, eco-friendly solutions for aging municipal gravity pipelines and potable water networks, helping cities build climate-resilient underground water infrastructure while minimizing ecological disruption, carbon emissions and non-revenue water loss.

CORE SUSTAINABLE ADVANTAGES

1 DRAMATICALLY CUT EXCAVATION & CARBON FOOTPRINT

Different from destructive open-cut digging and full pipe replacement, our UV-CIPP fully trenchless method rehabilitates pipelines internally via existing manholes and access points.

- Reduce road excavation, pavement breaking, soil excavation and construction waste by over 90%

- Slash fossil fuel consumption of heavy excavators, loaders and hauling trucks, lowering greenhouse gas emissions significantly

- Shorten construction periods greatly, reduce road closure, traffic congestion and disturbance to residents, businesses and urban vegetation

2 ZERO VOC EMISSION & HARMLESS CURING PROCESS

Our advanced UV light curing system outperforms traditional hot water/steam cured CIPP in environmental safety:

- Styrene-free, low-VOC resin formula, no harmful volatile gas release during curing

- Odorless, temperature-controlled UV curing, no thermal damage to surrounding soil, tree roots, buried cables and adjacent structures

- Safer working environment for construction crews and nearby communities, suitable for projects near schools, hospitals, parks and ecologically sensitive zones

3 MAXIMIZE WATER CONSERVATION & REDUCE ECOLOGICAL POLLUTION

Aging cracked pipelines cause massive underground leakage, groundwater contamination and huge non-revenue water (NRW) waste. Pro-liner seamless liner thoroughly seals all defects:

- Eliminate pipeline infiltration and exfiltration, stop sewage leakage polluting soil and groundwater

- Recover massive volumes of lost drinking water for water supply systems

- Smooth inner liner improves hydraulic flow capacity, cuts long-term pump energy consumption

4 ULTRA-LONG SERVICE LIFE FOR CIRCULAR INFRASTRUCTURE

Our high-strength lightweight liner features outstanding corrosion, abrasion and chemical resistance:

- Design service life of 50+ years after one-time rehabilitation

- Extend the service life of original host pipelines, avoid repeated reconstruction and resource waste

- Lower whole-life cycle maintenance cost and secondary environmental impact for municipal asset owners

5 PRO-LINER’S INTERNAL SUSTAINABLE OPERATION SYSTEM

As a national high-tech and specialized “Little Giant” enterprise, Pro-liner practices sustainable development internally:

- Green R&D: Optimize resin formulation to reduce raw material consumption, develop waterproof, anti-puncture customized liners for flood emergency repair

- Intelligent Manufacturing: Adopt smart workshop production to improve material utilization and control production waste

- Standardized Site Management: Promote standardized, low-noise, low-waste construction across global project sites

- ESG Compliance: Align product design with international drinking water certification standards for global market green access
