About this product

Product information from the supplier.

The Malleable Iron 90° Reducing Elbow with Electrophoretic Coating represents a significant leap in piping engineering, integrating a precision-molded bend and diameter reduction into a single, seamless component. By eliminating traditional connection points, this innovative design effectively removes potential leakage sites while optimizing fluid dynamics with a 1.5D curvature radius that reduces resistance by up to 40%.

Engineered for extreme environments, this fitting features a 360° full-coverage epoxy electrophoretic coating on both inner and outer walls. Combined with finite element analysis for optimized wall thickness and structural strength, it ensures unmatched stability and corrosion resistance for critical industrial applications, from chemical processing to marine systems.

Frequently Asked Questions

Q: What are the primary benefits of electrophoretic coating over traditional painting?

Electrophoresis provides 360° full coverage, including inner walls, ensuring a uniform thickness of 40-45μm that is significantly more resistant to corrosion and salt spray (≥1200 hours) than spray painting.

Q: How does the integral design of the reducing elbow improve system safety?

By combining the 90° bend and the reduction transition into one molded piece, it eliminates the need for a separate reducer and elbow, removing a potential leak point and reducing the total number of joints in the system.

Q: In which industrial environments is this malleable iron fitting most effective?

It is ideal for chemical piping in corrosive environments, marine cabin layouts with limited space, wastewater treatment plants, and coastal facilities exposed to severe salt spray.

Q: What is the maximum operating pressure and temperature for these fittings?

These fittings are designed for high-performance use with an operating pressure up to 4.0 MPa (PN40 level) and a wide temperature tolerance range from -30℃ to 130℃.

Q: Can these fittings be used for food-related applications?

Yes, while the standard is black epoxy, we offer specialized FDA-compliant coating options specifically designed for food-grade applications upon request.

Q: How should the reducing elbow be installed to prevent coating damage?

We recommend using a nylon protective wrench during installation to avoid scratching the coating and performing a pressure test 48 hours after installation to ensure a perfect seal.
