PPR Fittings

PPR Pipe Fittings can significantly improve the overall life and safety of the water supply and drainage system.

In the ever-evolving landscape of infrastructure development and urban planning, the reliability, safety, and efficiency of water supply and drainage systems have become critical concerns. From high-rise buildings to rural water networks, the demand for superior piping materials has grown exponentially. Among the many options available in the market, PPR (Polypropylene Random Copolymer) pipe fittings have emerged as one of the most reliable and safe solutions, known for their durability, thermal stability, and chemical resistance.

One company that has continually set benchmarks in the production and innovation of PPR pipe fittings is Shanghai Zhongsu Pipe Co., Ltd (ZHSU). Established in 2004 with a registered capital of 1.01 billion RMB, ZHSU has grown to become a leading manufacturer in China’s plastic piping industry. Headquartered in the Jinshan district of Shanghai, the company occupies a sprawling 70,000 square meter facility dedicated to advanced pipe manufacturing and research.

Polypropylene Tube Fittings play an essential role in both water supply and drainage systems, particularly due to their high temperature and pressure resistance, non-toxic nature, and long service life. Unlike traditional metal pipes that are prone to corrosion, scaling, and leakage, PPR pipes maintain water quality and ensure system integrity over decades of use.

Their use significantly enhances the overall safety of the water system by reducing risks of contamination, leaks, and premature failures. Moreover, PPR fittings are heat-fusible, meaning joints are seamlessly welded together, minimizing the chances of leakage and ensuring long-term durability.

ZHSU has positioned itself at the forefront of the piping industry by combining world-class production capabilities with rigorous quality control. The company specializes in the production of PPR pipe & fittings, antibacterial PPR pipe & fittings, anti-UV PPR pipes, PP-RCT pipes, and HDPE pipes and fittings. To meet the increasing market demand for high-quality plastic pipes, ZHSU has adopted high-tech production lines that boost productivity and enable quick delivery timelines.

ZHSU’s CNAS-certified national laboratory plays a pivotal role in maintaining product quality. This ensures that all products undergo meticulous testing and inspection procedures before reaching the customer. From raw material selection—using only 100% virgin raw materials from globally recognized suppliers like Borealis (Austria), South Korea, and top domestic brands—to final product delivery, ZHSU maintains a tightly monitored production process.

These efforts are supported by the company’s ISO9001, ISO14001, and OHSAS18001 certifications, further testifying to its excellent management systems in quality, environmental responsibility, and occupational health and safety.

These products are widely used in building water supply and drainage systems, municipal engineering, underground drainage and sewage discharge systems, and rural water network transformation projects. The comprehensive applicability of ZHSU’s piping solutions highlights their commitment to building resilient water infrastructure.

Their market reach extends far beyond China, with strong presence in Southeast Asia, Africa, and Latin America, gaining recognition for providing safe, reliable, and cost-effective plastic piping systems.

Pioneering in Large Diameter PE Pipes
To meet the evolving demands of large-scale infrastructure projects such as rural drinking water safety initiatives and nuclear power plant developments, ZHSU has invested in specialized production equipment for large-diameter PE pipes. The company now boasts the capability to produce PE pipes with diameters up to DN1200mm, making it one of the few manufacturers in China capable of such output.

This development reflects ZHSU’s strong commitment to technological innovation and infrastructure support at both national and international levels.

As global awareness around environmental protection and sustainable development intensifies, ZHSU has aligned its operations with these principles. The use of virgin raw materials ensures that their products are non-toxic, recyclable, and environmentally friendly.

ZHSU operates under the philosophy: "Cherish every drop of water—this is our social responsibility and mission." This principle not only reflects in their manufacturing processes but also in their strategic initiatives to contribute to safe drinking water and sanitation projects in underserved regions.

Furthermore, the incorporation of antibacterial technology in certain PPR product lines adds a layer of health protection, particularly valuable in residential and public infrastructure where water purity is critical.
