Product introduction
Product Title
HFW Zinc Rich Primer Coated Pipe 76~660mm Underground Anti-rust Pipeline
Brief Introduction
This HFW (High-Frequency Welded) pipe is coated with zinc rich primer, specially developed for underground buried pipeline projects. Manufactured through advanced HFW forming & welding technology, the steel substrate features stable mechanical performance, excellent dimensional accuracy and uniform wall thickness. The zinc rich primer coating provides outstanding cathodic protection, isolating the steel matrix from soil moisture, chloride ions and corrosive media, effectively slowing down underground electrochemical corrosion. With outer diameter range 76mm to 660mm, the product is widely applied in municipal water supply, sewage, underground cable casing, foundation drainage and buried structural piping. Hebei Huayang's full-process quality control guarantees consistent coating adhesion, no peeling and long-term anti-rust performance for buried service.

Production Process & Performance
Raw Material Preparation High-quality hot rolled steel coil is selected, with chemical composition inspection and edge trimming. Strip flatness and edge parallelism are strictly controlled to guarantee stable forming quality.
HFW High-Frequency Welding Adopt high-frequency resistance welding, no filler metal. Weld seam is forged by extrusion rolls. Online scarfing removes inner & outer flash, making weld surface flush with base metal. Online weld normalization eliminates welding residual stress and balances weld and base metal mechanical properties.
Surface Pretreatment Pipe surface goes through blasting / grinding to remove rust, oil and oxide scale, reaching required cleanliness and roughness, ensuring strong bonding between substrate and zinc rich primer.
Zinc Rich Primer Coating Zinc rich primer is uniformly sprayed or brushed on pipe outer surface. High zinc content provides sacrificial cathodic protection. When coating suffers minor scratches, zinc powder will corrode preferentially to protect steel pipe from rusting. The coating resists soil corrosion, damp environment and underground chemical erosion.
Inspection & Testing 100% online ultrasonic flaw detection for weld seam. Hydrostatic pressure test, dimensional inspection, coating thickness test and adhesion test are carried out by batch before delivery.

Packaging, transportation and delivery
Packaging, transportation and delivery
At Hebei Huayang Steel Pipe Co., Ltd., we apply standardized and reliable packaging solutions for all our steel pipe products. Our pipes can be securely packed by hexagonal bundling or circular bundling according to product diameter, wall thickness and customer requirements. Each pipe end is protected with high‑strength plastic pipe caps to avoid collision damage, dust and moisture during transportation and storage. The whole bundle is firmly wrapped with durable woven bags to enhance stability and prevent scratches or deformation.
We support a complete range of transportation methods to satisfy global customers, including road transportation, railway transportation, sea freight and container shipping. Based on our strategic location in Cangzhou, Hebei Province, we enjoy convenient access to major ports such as Tianjin Port, which greatly improves logistics efficiency and reduces transportation costs.
For standard specifications and normal order quantities, the general delivery time is about 30 days after order confirmation and deposit receipt. For large‑scale orders, special sizes or customized processing requirements, our production and sales team will formulate a detailed production plan and provide an accurate delivery schedule accordingly to ensure on‑time supply and stable performance for projects and clients worldwide.
Strict quality control
1. During and after the production, experienced quality inspectors randomly check the products to ensure that each steel pipe is qualified for production and application.
2. A nationally recognized laboratory with CNAS certification and certification by French Classification Society.
3. Have CNOOC access certificate, KOC oil company access network, ADNOC Abu Dhabi oil company access network, Petrobras access network, etc.
4. Accept the inspection by the third party designated/paid by the buyer, such as SGS and BV.
