Advanced Production Equipment
Zhongtong operates multiple automated large-diameter production lines capable of manufacturing PE pipes up to 1,200 mm in diameter, backed by extensive experience in large-diameter and heavy-wall pipe production.
Long-length pipe fabrication and supply options help reduce on-site joints and welding work. They are suited to long-distance water transmission, drainage, and other projects requiring extended continuous pipe runs.
Custom-fabricated PE fittings can be produced to suit project pipe sizes, connection methods, and installation requirements, including elbows, tees, and other special configurations. Fabrication and welding capabilities support large pipeline networks and non-standard connection requirements.


We coordinate packaging protection, CAD container loading planning, and shipment of pipes & supporting accessories according to pipe specifications, lengths, quantities and project schedules.
Based on the different structures of PE pressure pipes, corrugated pipes, composite pipes, and power protection conduits, we help confirm suitable connection methods, including butt fusion, electrofusion, flanging, socket joint, coupling, or sealing ring connection, and match corresponding fittings and welding equipment.
We provide product documents and guidelines for open-cut, trenchless, underground, above-ground, bracket and hoisting installation according to product types and site conditions.








PE pipe is one of the most widely used plastic pipes in municipal infrastructure. It is extensively adopted in urban and township municipal pipe networks, mainly for domestic water supply, rainwater drainage, sewage collection and transportation, and buried town gas pipelines. It is also suitable for renewal of aging urban pipelines, pipe laying alongside roads, and rainwater harvesting & regulation projects for sponge cities. Featuring excellent sealing performance, settlement resistance, corrosion resistance, zero leakage, and maintenance-free properties, it adapts to complex soil conditions and heavy-load buried road environments, serving as the primary pipe for municipal water supply, drainage, and gas networks.

It covers all scenarios of modern agriculture and rural water conservancy construction, including large-area farmland water diversion, field irrigation networks, flood drainage, water-saving upgrading of high-standard farmland, and systematic water supply for orchards and greenhouses. It is also applied in centralized rural water supply, mountain water diversion, and landscape water delivery projects. With high toughness, low-temperature resistance, and resistance to soil saline-alkali corrosion, the pipe can be laid flexibly along terrain and resist geological settlement, ideal for long-term buried application in fields and outdoor environments.

Widely used for fluid transmission in factories, mines, and environmental protection projects. It is suitable for transporting weak acid & weak alkaline industrial wastewater, process water, mine tailings, ore slurry, and fly ash. Additional applications include leachate collection at landfills, underground heat exchange pipelines for ground-source heat pumps, and supporting pipelines for sewage treatment plants. With outstanding chemical resistance, anti-scaling properties, and high wear resistance, it withstands complex industrial media and harsh buried conditions over a long service life.

Widely used for external supporting pipe networks of residential communities, commercial buildings, resettlement housing, and urban complexes, including outdoor domestic water supply, rainwater & sewage drainage, and landscape irrigation within parks. It can also be used for temporary water supply at construction sites, as well as protective sleeves for weak-current and low-voltage cables. Easy to install, cost-effective, and long-lasting, it perfectly meets the requirements of outdoor pipe networks for residential projects.

Widely adopted in major national transportation infrastructure projects, including pre-buried protection for power cables, signal cables, and monitoring cables in expressways, national & provincial highways, bridges, tunnels, airports, high-speed railway stations, ports, and rail transit systems. It fits trenchless construction scenarios crossing roads, rivers, and railways. Featuring high strength, superior insulation, compression, and impact resistance, it meets the high standards and long-lasting cable protection requirements of large-scale transportation projects.

Power conduits serve as core protective pipes for urban power infrastructure. They are mainly used for urban power grid upgrades, underground conversion of overhead cables, pre-buried power pipe networks along municipal roads, and cable protection systems in utility tunnels. They provide buried protection for urban high- and low-voltage distribution cables and main grid cables. Resistant to heavy road loads, soil corrosion, and geological settlement, they ensure the long-term safe and stable operation of urban power grids and are standard pipes for municipal power projects.

It applies to various civil and outdoor water delivery scenarios such as aquaculture water transmission, landscape water circulation, mountain water diversion, and temporary outdoor pipelines, for light-duty, long-service, and corrosion-resistant fluid conveying conditions.
