  Heavy-Duty Spray Pipe (Shotcrete Hose) – HG/T 2192-2008 Standard Steel Wire Reinforced Hose for Tunnels & Mining

  Product Overview

  Our Spray Pipe (Shotcrete Hose) is engineered for demanding high-pressure concrete and abrasive media spraying applications in heavy infrastructure, tunnel construction, and mining. Manufactured to meet the HG/T 2192-2008 standard, this hose is constructed with an ultra-wear-resistant inner rubber tube, a high-tensile woven steel wire reinforcement layer, and a durable natural rubber outer cover.

  Designed to convey highly abrasive materials such as cement, sand, and mortar, this hose features exceptional flexibility and resistance to kink, impact, and internal wear. With a high operating pressure rating of 30 bar (450 psi) and a safety burst pressure of 90 bar (1350 psi), it guarantees reliable, continuous performance under extreme conditions ranging from -30°C to +80°C.

  Key Features & Benefits
