As a senior engineer specializing in dielectric isolation systems, I can confirm that the Dielectric Isolation Kit (Type E, DN400, 600LB) offered by this Chinese Manufacturer represents a reliable, cost-effective solution for cathodic protection and stray-current mitigation in critical piping networks. Designed strictly per ASME B16.5, the kit combines G10 insulating rings, Viton O-rings, and ZPS washers—materials proven to resist hydrolysis, creep, and thermal cycling in aggressive media such as sour gas, seawater, and chemical slurries.
The DN400 bore (nominal 400 mm) fits large-diameter flanges commonly found in refinery transfer lines, offshore platforms, and water treatment plants. Its 600LB pressure class (≈10.3 MPa at ambient temperature) ensures integrity under surge conditions, while the compact profile allows retrofitting without pipe rerouting. Unlike generic kits, this unit undergoes 100% dielectric strength testing (minimum 500 V/mil) and torque-retention validation, guaranteeing stable insulation resistance even after repeated thermal shocks.
What sets this Chinese Manufacturer apart is their flexible MOQ (1 set), rapid 7–30 day delivery, and full customization—from bolt-hole patterns to overlay thickness—without compromising the ASME footprint. The Viton seal offers exceptional resistance to hydrocarbons and ozone, while ZPS (zinc-plated steel) spacers provide sacrificial corrosion protection, extending flange life by up to 40% in coastal environments. For plant engineers, this kit reduces annual maintenance frequency and eliminates the need for external bonding jumpers in many non-critical zones.
Priced at USD 199/set, it undercuts European equivalents by nearly 60%, yet meets ISO 9001 and API 6A-compatible manufacturing standards. I recommend pairing it with torque wrenches calibrated to 200–250 N·m for optimal gasket compression. Whether you are upgrading existing cathodic protection systems or designing new skids, this Dielectric Isolation Kit delivers field-proven performance, backed by technical datasheets, 3D models, and installation videos available on request. Investing in this kit means prioritizing pipeline integrity, reducing unplanned shutdowns, and achieving long-term ROI—especially when procured directly from a seasoned Chinese Manufacturer with over 15 years of export experience to Americas, MENA, and Southeast Asia.
FAQ
Q1: Can this kit be used for NPT threaded flanges?
A: No—it is designed for ASME B16.5 raised-face or flat-face flanges only; threaded connections require different isolation sleeves.
A: No—it is designed for ASME B16.5 raised-face or flat-face flanges only; threaded connections require different isolation sleeves.
Q2: Is the G10 material FDA-compliant for food contact?
A: No—G10 contains epoxy and glass fiber; use PTFE-based kits for food-grade applications.
A: No—G10 contains epoxy and glass fiber; use PTFE-based kits for food-grade applications.
Q3: How do I verify the 600LB rating at 200°C?
A: Derating applies—max working pressure drops to ~430LB at 200°C; refer to our pressure-temperature chart.
