RM® manufactures high-performance double-wall pipes specifically designed for concrete pumps where high wear resistance is required. The system consists of two layers: a heavy-duty inner wall subjected to heat treatment to ensure high abrasion resistance, and an outer wall that provides impact protection and serves a containment function.
We offer a complete range of double-wall pipes in different types, diameters, and lengths to meet every specific application.
Using RM® double-wall pipes ensures a long operating life, reducing the frequency of replacements and costly downtime. Our products offer consistent performance even in the most demanding civil, infrastructure, and industrial construction projects, ensuring that construction job sites remain productive at all times.
Strength and durability
Proven reliability: E 700 series has been tested for years and guarantees high performances recognized worldwide.
Key Features: the two-layer pipe is designed specifically for conveying abrasive materials. The inner pipe is uniformly hardened to 63 HRC, providing high wear resistance and long service life, the outer pipe protects the inner pipe from torsional, bending and impact forces, ensuring the integrity of the inner pipe even under the most extreme conditions.
Outstanding performances
Excellence in durability and strength: E 900 series is specifically designed to deal with the most extreme conditions, ensuring long-lasting performances even with highly abrasive materials.
Key features: the wear layer of the inner pipe is tempered to a hardness of 67 HRC, offering superior strength primarily in high-wear applications, ensuring long operating times without any downtime; the outer pipe provides optimal protection against torsional, bending and impact forces, preserving the integrity of the pipe even under the most challenging conditions.
