Durable Double-Layer Elbow DN100 90° R180 for High-Rise Concrete Pumping

This double-layer elbow features a nominal diameter of DN100, a 90° angle, and a bend radius of R180. Manufactured with quenched inner wall for superior wear resistance, it is designed for high-rise building concrete pumping applications. Backed by our case study with a construction company, this elbow has demonstrated stable operation and 30% longer lifespan in a 3-year high-rise project.

Key Selling Points

• Quenched Inner Wall: Surface hardness HRC 58-62 ensures exceptional abrasion resistance, reducing replacement frequency.
• 2-3 Times Longer Lifespan: Compared to ordinary elbows, our double-layer design extends service life significantly, lowering total cost of ownership.
• Customizable Parameters: Available in DN125, DN150, various angles (45°, 30°, 15°) and bend radii to match specific pump systems.
• ISO 9001 Certified: Manufactured under strict quality management system (ISO 9001:2015) ensuring consistent quality.
• Proven in High-Rise Projects: Our case study shows 50 units used in a high-rise building project with 30% longer lifespan.

Technical Specifications

Models and Options

This variant is DN100/90°/R180. Other options include DN125 and DN150, angles 45°, 30°, 15°, and bend radii R190.5 and R275.

Materials and Structure

The double-layer construction consists of a quenched inner wall for wear resistance and an outer layer for structural integrity. The inner wall undergoes heat treatment to achieve HRC 58-62 hardness.

Applications

Specifically designed for high-rise building concrete pumping where wear resistance and reliability are critical. Also suitable for medium-pressure continuous operation (8-12h/day).

Customization

We offer customization in diameter, angle, bend radius, and surface treatment. MOQ: 1 piece (sample order available). Delivery: FOB/CIF/EXW.

Case Study

A construction company used 50 units of our DN100 double-layer elbows in a high-rise building project. After 3 years of continuous use, the elbows showed stable operation with 30% longer lifespan compared to standard elbows.
