TüV-Certified. Europe-Proven. Technology-Driven. HengTong is not a typical manufacturer — we are a high-end, export-oriented producer dedicated to international markets since 1997.
HengTong has over 20 years of EN877 production experience, developed in collaboration with European partners. We offer full system capability covering SML, KML, TML, and BML, and have been recognized as a reliable partner for complex EN877 projects.
Our manufacturing is TüV-certified, ensuring compliance with European standards and rigorous factory-level quality control.
HengTong produces pipes ranging from DN40 to DN600, including DN500 and DN600, making us the only reliable source for large-diameter EN877 projects.
We pioneered EN877 epoxy-coated pipes in ASTM sizes for the U.S. market and continuously develop new solutions through R&D collaborations with leading universities and institutes.
HengTong follows three strict principles: we produce only high-end export products, work directly with overseas clients, and do not engage in price wars. This approach ensures stable quality, higher margins, and long-term partnership value.
Our products have been sold in over 20 countries, with early entry into the U.S. and European markets. HengTong has proven success in premium segments, consistently delivering high-end products at competitive value.
HengTong delivers what others claim — real EN877 quality, certified by TüV, proven in Europe, and built for high-end markets.
