3PE Anti-Corrosion 90° Steel-to-PE Elbow Transition Fitting

The 3PE Anti-Corrosion 90° Steel-to-PE Elbow Transition Fitting is a specialized pipeline connector designed for right-angle transitions between PE piping systems and steel pipelines. One end features a polyethylene elbow structure suitable for butt fusion or electrofusion welding with PE pipes, while the steel end is protected with a high-performance 3PE anti-corrosion coating system.

The steel-to-plastic bonding area is manufactured through an integrated composite molding process, ensuring exceptional sealing performance and long-term structural stability.

Combining pipeline redirection, steel-to-PE transition, and anti-corrosion protection in a single fitting, this product is ideal for wall penetration, underground turning points, vertical riser connections, road crossing projects, and equipment pipeline connections. It is widely used in municipal gas systems, potable water networks, industrial pipelines, and infrastructure renovation projects.

The 90° Steel-to-PE Elbow Transition Fitting is engineered for buried, above-ground, and high-moisture environments where corrosion resistance and reliable pipeline transition are critical.

Key Features & Benefits

Integrated 90° Elbow Design

The fitting features a factory-formed 90-degree elbow, allowing direct pipeline redirection without additional elbow fittings or adapters. This reduces the number of connection points, minimizes leakage risks, and simplifies pipeline layout.

Advanced 3PE Anti-Corrosion Protection

The steel section is coated with a three-layer polyethylene (3PE) anti-corrosion system consisting of:

Epoxy powder primer
Adhesive middle layer
Outer polyethylene protective layer

This structure provides outstanding insulation, waterproofing, and resistance to soil chemicals and underground corrosion, making it ideal for buried pipeline systems.

Strong Integrated Steel-Plastic Structure

Using high-pressure composite manufacturing technology, the steel and PE sections are tightly bonded into one solid structure. The fitting resists separation, cracking, and deformation caused by pressure fluctuations, thermal expansion, or ground settlement.

Excellent Sealing Reliability

The fitting incorporates a reinforced sealing structure to ensure superior gas-tight and water-tight performance. It meets demanding sealing requirements for municipal gas and water supply applications, providing long-term leak-free operation under pressure.

High Mechanical Strength

The steel end offers excellent rigidity and impact resistance, capable of withstanding external pressure, soil load, and mechanical stress. It is especially suitable for underground crossings, equipment connections, and vertical pipeline systems.

Seamless PE Fusion Connection

The PE side can be directly connected to polyethylene pipes using butt fusion or electrofusion methods. The welded joint becomes an integral part of the pipeline system, offering excellent resistance to aging and environmental stress.

Faster Installation & Reduced Risk

Traditional installations often require separate transition fittings and elbow connectors. This integrated solution combines both functions into a single component, reducing welding points, shortening installation time, and minimizing potential failure locations.

Excellent Weather & Environmental Resistance

The fitting performs reliably in low-temperature, high-temperature, humid, and chemically aggressive environments. Its long buried service life and maintenance-free performance help reduce long-term operating costs.
