View Drainage ConduitsVietnam is executing one of Southeast Asia's most aggressive digital transformation strategies under the National Digital Transformation Program to 2025 with orientations towards 2030 (Decision 749/QD-TTg). Led by major telecommunication network operators—including Viettel Group, VNPT (Vietnam Posts and Telecommunications Group), and MobiFone—the country is accelerating both widespread 5G commercial standalone networks and urban landscape aerial-to-underground cable conversions.
Under Prime Ministerial Directive 51/2019/ND-CP and municipal zoning mandates in Tier-1 metros such as Hanoi (Hoan Kiem, Cau Giay), Ho Chi Minh City (Districts 1, 3, Thu Duc City), Da Nang, and Hai Phong, overhead "spiderweb" fiber bundles must be relocated underground into unified multi-duct concrete chambers and specialized communication conduits. This structural shift has created a sustained demand for certified communication pipes capable of surviving Vietnam’s specific environmental challenges:
A rigorous review of resin chemistry, multi-duct extrusion geometries, and co-extruded silicon solid lubricants engineered for telecom contractors.
Unlike post-sprayed liquid lubricants that migrate and dry out in tropical heat, our telecom conduits feature a permanently bonded internal silicone solid lubricant lining. The dynamic friction coefficient is maintained under 0.08, enabling continuous air-blown fiber jetting distances exceeding 2,000 meters in a single shot without duct splitting or optical sheath burning.
Our 4-hole, 5-hole, and 7-hole cellular PVC communication pipes utilize internal rib reinforced structural division walls. This multi-compartment design eliminates internal micro-cable cross-tangling during re-pulling, while optimizing vertical compression resistance by 42% over standard round single-bore conduits, drastically cutting trench width requirements.
Tropical Asian OSP environments face severe biological damage from subterranean termites (Coptotermes gestroi) and localized rodents. We integrate non-toxic, long-chain organophosphate repellents and nano-calcium carbonate nucleating agents into the polymer matrix, preventing biological punctures without leaching hazardous heavy metals into groundwater aquifers.

Custom pipeline layouts and casing assemblies designed for civil engineering and telecommunications contractors.
The construction of Vietnam’s high-speed rail lines and expressways requires continuous OSP (Outside Plant) pipeline infrastructure along rights-of-way. HZXY provides paired multi-tube HDPE silicon-core bundles with integrated tracer wires and copper conductors, allowing accurate electromagnetic line location under unpaved gravel beds while facilitating rapid automated camera and telemetry cable upgrades.
Replacing aerial wiring in historic municipal centers requires compact civil disturbance. Our monolithic multi-hole PVC porous ducts allow civil contractors to achieve up to 7 separate cable pathways in a trench only 150mm wide. Coupled with our pre-formed bellmouth sockets and rubber sealing rings, field assembly requires zero on-site solvent welding, dramatically speeding up overnight city installations.
Subsea fiber landing points in Quy Nhon, Da Nang, and Vung Tau face aggressive coastal salinity and wave action. HZXY provides high-molecular-weight thick-wall PE100-RC communication sleeves paired with hot-dip galvanized rigid structural steel casings (coating weight > 610 g/m²). This prevents both chemical oxidation and physical abrasion from shifting underwater sandbars.
Headquartered in the Daqiuzhuang Industrial Zone, Jinghai District, Tianjin—one of the world’s densest industrial manufacturing and materials processing epicenters—Tianjin Huizhong Xinyu (HZXY) operates across 1,500 acres of manufacturing facilities in Tianjin and Tangshan. With an annual capacity surpassing 10 million metric tons across structural steel, steel tubing, and advanced synthetic utility conduits, we remove the supply bottlenecks common to regional distributors.
For engineering projects in Vietnam, our automated extrusion lines run 24/7 with laser-guided wall-thickness controllers and gravimetric dosing systems ensuring exact resin uniformity. Furthermore, our geographical proximity to Tianjin Xingang Port provides unmatched maritime logistics:
Ensuring your consignments pass project owner verification, QUATEST 3 laboratory inspections, and Vietnamese customs clearance smoothly.
Our pipe systems are strictly produced in compliance with TCVN 8699:2011 (Porous plastic pipes used for telecommunication underground cable networks), TCVN 7997:2009 (Electric cables - Installation of underground cables), alongside international benchmarks including ASTM F2160, ISO 4427, and Bellcore GR-356-CORE. Full Mill Test Certificates (MTC) and 3.1 batch inspection reports accompany every shipment.
Under the ASEAN-China Free Trade Area (ACFTA) agreements, HZXY issues official Certificate of Origin Form E. This allows Vietnamese import entities to import communication conduits and structural steel pipes under 0% preferential import duty (HS Codes 3917.21, 3917.23, and 7306.30), significantly improving total project margins compared to sourcing from non-pact regions.

Mill test reports covering mechanical tensile strength, Vicat softening temperature, elongation at break, and ring stiffness are issued with every export lot.
Yes. Under the ASEAN-China Free Trade Area (ACFTA) agreements, HZXY prepares and issues authenticated Form E Certificates of Origin. This grants eligible Vietnamese importers a 0% preferential customs tariff on PVC porous communication conduits, HDPE telecom pipes, and carbon steel profiles, avoiding the 5% to 15% standard MFN tariff applied to non-treaty shipments.
Thanks to our permanently co-extruded solid silicone core layer—which maintains a dynamic friction coefficient (µ) of less than 0.08—contractors using standard optical fiber air-blowing machines (such as Plumettaz or Fremco units) reliably achieve single-shot blowing distances between 1,500 and 2,200 meters under proper pneumatic pressure (12–14 bar), even along undulating terrain in Central Vietnam.
Because HZXY operates both extensive steel profile rolling facilities and advanced plastic polymer extrusion plants across our 1,500-acre industrial bases, we offer full project Bill of Materials (BOM) consolidation. We frequently bundle communication conduits, galvanized steel substation pipes, H-beam mast supports, lightning protection flat steel bars, and industrial water control valves into unified container bookings. This eliminates the management overhead of multiple disparate factories and significantly reduces port handling and LCL logistics costs.
Our production facilities in Daqiuzhuang, Tianjin, are located just 60 km from Tianjin Xingang Port. Standard maritime container transit times are 5 to 7 days to Hai Phong Port (serving Northern Vietnam: Hanoi, Bac Ninh, Hai Duong) and 8 to 11 days to Cat Lai / SP-ITC Ports in Ho Chi Minh City (serving Southern Vietnam: Binh Duong, Dong Nai, Long An). Standard stocked sizes can be loaded within 48 to 72 hours of PO confirmation.
Yes. We offer fully customized duct branding according to telecommunication client requirements (e.g., specific pantone orange for Viettel, blue for VNPT, or customized identifying color-stripes). Conduits are hot-foil or laser-printed with sequential meter markings, production date, standard compliance codes, and contractor names every 1 meter with high abrasion resistance.
We welcome third-party technical inspection agencies—including SGS, Bureau Veritas (BV), TÜV SÜD, and Cotecna—appointed by the buyer. Inspectors can access our warehouse to verify pipe outer/inner diameters, wall thickness tolerances, ring stiffness, impact resistance at 0°C, and bundle packaging integrity before factory seal dispatch.
