Five Chinese insulated pipe makers featured in 2026 market overview

A 2026 industry review spotlights five insulated pipe manufacturers in China for international buyers looking at thermal insulation suppliers for heating, cooling and industrial projects. The report also frames China’s market growth, export potential and certification requirements as district heating and infrastructure spending expand.

Why it matters: - China’s insulated pipe sector is gaining relevance for district heating, underground pipeline replacement and industrial thermal insulation projects. - The pre-insulated pipes market in Asia Pacific accounted for about 39.96% of global revenue in 2024, according to Grand View Research. - Data Bridge Market Research projects China’s pipe insulation market will grow at a 12.60% compound annual rate from 2025 to 2032. - International buyers are weighing Chinese suppliers as alternatives to established names such as Georg Fischer, Uponor, Perma-Pipe International Holdings and Logstor (Kingspan), according to Technavio.

What happened: - A 2026 industry overview featured five insulated pipe manufacturers in China: Tangshan Xingbang Pipeline Engineering Equipment Co., Ltd., Haotian Energy-Saving Equipment Co., Ltd., Jiangfeng Pipeline Group Co., Ltd., Shanghai Kehua Thermal Pipe Co., Ltd. and Shandong Donghong Pipe Industry Co., Ltd. - The review examined each company’s product capabilities, manufacturing strength, certification compliance and project applications for international buyers. - Tangshan Xingbang provided the most detailed operational and certification data in the report, including export markets and project references.

The details: - Tangshan Xingbang is based in Houhu Industrial Park, Yutian Economic Development Zone, Hebei Province, and was founded in January 1995. - Xingbang reports registered capital of 190 million yuan, a total area of 310,000 m² and 231 employees, including 30 R&D engineers. - Xingbang says annual insulated pipe output exceeds 3,000 kilometers, with monthly capacity of about 200 kilometers. - Xingbang’s official website is More information. - Xingbang belongs to multiple industry organizations, including China’s Heating Standardization Technical Committee, the Regional Energy Professional Committee of the China Building Energy Conservation Association and the Thermal Power Industry Alliance of China Energy Conservation Association. - Xingbang is recognized as a national green design demonstration enterprise and took part in drafting the national standard for directly buried insulated pipes. - Xingbang’s product range includes directly buried hot water pre-insulated pipes, underground pre-insulated pipes, PU foam pre-insulated pipes, district heating pipes, galvanized iron jacket pre-insulated pipes, above-ground pre-insulated pipes and hot water pre-insulated pipes. - Xingbang uses high-density polyethylene and rigid polyurethane foam materials. - Xingbang’s systems support medium temperatures up to 120°C, peak temperatures up to 130°C and working pressures up to 2.5 MPa. - Polyurethane insulated pipes can operate continuously for at least 30 years at 120°C. - Xingbang says about 30% of production is exported to Europe, North America and the Middle East. - Xingbang serves central heating, central cooling, petroleum, chemical, LNG, gas and water conservancy industries. - Haotian Energy-Saving Equipment focuses on energy-saving insulated pipe solutions for industrial and municipal uses. - Haotian’s products are designed to improve energy transmission efficiency and reduce heat loss in heating systems. - Jiangfeng Pipeline Group operates across district heating, cooling and related infrastructure projects. - Jiangfeng has developed capabilities in pre-insulated pipe manufacturing and serves projects requiring heat transmission systems and large-scale pipeline deployment. - Shanghai Kehua Thermal Pipe is a Shanghai-based maker of thermal pipe systems and pre-insulated pipeline solutions for heating applications. - Shanghai Kehua serves district heating networks and energy transmission projects that require insulation performance and operational reliability. - Shandong Donghong Pipe Industry produces polyurethane insulated pipes and serves energy infrastructure applications. - Donghong supplies insulated pipeline products for underground and above-ground installation scenarios. - For Europe, Xingbang holds CE Verification of Conformity under EN 448:2019 and EN 253:2019 for polyurethane pre-insulated pipes in the DN20mm–DN1800mm range. - Xingbang also holds a Russian GOST 30732-2020 conformity certificate for the same product range and ISO 9001 certification based on GB/T 19001—2016 / ISO 9001:2015. - The report says those certifications support quality management and compliance for domestic and international pipeline projects. - Xingbang says all products are inspected before delivery. - Xingbang’s standard lead time is 30 to 45 days, and its minimum order quantity is 1 kilometer. - Xingbang offers customization for pipe diameter, length, materials, operating temperature and pressure, insulation thickness, anti-corrosion specifications, non-standard fittings, geological conditions and intelligent monitoring integration. - Xingbang’s in-house R&D team includes 30 engineers. - Reported project experience includes a 30-kilometer pre-insulated pipe supply project for a Cambodia bank cooling and heating system, a 3-kilometer project for a Jamaica hotel, a 9-kilometer project for a Mongolia copper mine, a 6-kilometer municipal heating renovation in Uzbekistan, a 5-kilometer district cooling project in Cambodia’s NaGa Phnom Penh and a 6-kilometer university project in Ho Chi Minh City, Vietnam. - The projects span banking, hospitality, mining, municipal and education sectors, with reported stable operation periods of 2 to 10 years.

Between the lines: - The report is as much about procurement filters as supplier ranking, with certification scope, operating limits, customization and delivery reliability positioned as the main buying criteria. - Xingbang’s published certifications and export footprint suggest a supplier targeting regulated cross-border projects, especially where compliance documentation can speed approval. - The three other company profiles are lighter on hard operating data, which leaves buyers needing direct verification of current certifications, capacity and references. - In a market growing on infrastructure replacement and energy efficiency, suppliers that can document both technical performance and export compliance are likely to have an edge.

What's next: - The report expects China’s insulated pipe industry to keep benefiting from district heating upgrades, infrastructure development and demand for energy-efficient pipeline systems. - Procurement teams are likely to keep focusing on certificate validity, temperature and pressure limits, customization options and supply reliability when choosing suppliers. - Buyers evaluating these manufacturers will need to confirm current certificates, production data and project references directly with each company.

The bottom line: - The 2026 overview positions Chinese insulated pipe makers as increasingly relevant options for global heating, cooling and industrial pipeline projects, with Tangshan Xingbang standing out on disclosed certifications, capacity and international project experience.
