PVC coated galvanized pipe takes hot-dip galvanized carbon steel pipe as substrate. After strict surface pretreatment, high-adhesion PVC material is coated on outer or both inner-outer surfaces under professional production process. The tight combination between galvanized substrate and PVC coating blocks erosion from humid air, soil, acid-alkali medium effectively.
Our factory supports multiple dimension options for outer diameter, wall thickness and pipe length. The PVC coating can be customized into black, blue, gray and other colors. Products comply with GB, ASTM and related international industry standards. It can be cut, threaded and processed on-site conveniently. We provides one-stop service including drawing review, sample confirmation, batch production, third-party inspection and complete technical document delivery.
Product Advantages
Double-layer Anti-corrosion Performance
Hot-dip galvanized substrate plus compact PVC coating, double protection against rust, acid, alkali and soil corrosion, greatly extend service life under underground or humid environment.
High Mechanical Strength
Retain the original pressure-resistance and impact-resistance feature of galvanized steel pipe, not easy to crack or deform during transportation, burial and construction.
Smooth Medium Flow Surface
PVC coating keeps inner wall smooth, reducing fluid resistance, not easy to scale, lowering pipeline blockage risk.
Flexible On-site Processing
Supports cutting, threading, welding end treatment, compatible with conventional pipe fittings for quick field installation.
Customizable Coating Solution
Outer-only coating or inner-outer double-sided PVC coating are optional; various coating thickness and colors available for different project requirements.
Stable Comprehensive Compliance
Manufactured under full-process quality control, matching ISO9001 system requirement; can offer material certificate and third-party test report upon request.
Product Application
This series composite pipe fits multiple engineering scenarios. For municipal projects, it works for underground water-supply pipelines, sewage pipelines and cable protection conduits. In industrial fields, it delivers low-corrosive chemical fluid for workshops and factory zones. It is also suitable for farmland irrigation, building fire-fighting piping, outdoor cable shielding, landscape water system construction. According to medium property and buried environment, we recommend suitable coating scheme for above-ground laying, direct burial and trench laying working conditions. Matching pipe fittings such as elbows, tees and flanges can be supplied together to realize full-set pipeline supporting delivery.
FAQ
Q: Can you supply matching pipe fittings that share the same anti-corrosion standard with the steel pipes?
A: Yes. Elbows, tees, reducers and flanges can be produced with identical galvanizing and PVC-coating process to guarantee full-set pipeline anti-corrosion consistency.
Q: What technical parameters should be confirmed for ordering pvc coated galvanized pipe?
A: Please confirm outer diameter, wall thickness, single-piece length, inner-outer or single-side coating requirement, medium property and operating environment. These information help us confirm coating thickness and formulate accurate quotation.
Q: What test documents can you provide before shipment?
A: We can provide complete pre-shipment documents including mill test certificate (MTC), dimension inspection report, coating thickness test record, ISO qualification certificates and third-party inspection reports. All documents support customs clearance and project acceptance.
