wear resistant sand blasting hose assembly

Wear Resistant Sand Blasting Hose Assembly

This wear-resistant sandblasting hose assembly is specially designed for pneumatic conveying working conditions of chemical and metallurgical equipment, suitable for transporting mixed media of coal powder and nitrogen. The inner hose is made of special high wear-resistant rubber, resisting high-speed impact and abrasion from coal powder particles, no delamination or wear-through, with much longer service life than ordinary hoses. It works stably at -35℃～+80℃, resisting high and low temperature aging without hardening or deformation. The rated working pressure is 1.6MPa, with stable pressure resistance and pulse resistance, no bulging or bursting during operation. Adopting precise crimping technology, the hose and joints are tightly connected with good sealing, no powder leakage or air leakage. Ideal for coal powder conveying, pneumatic feeding and dust conveying in chemical and metallurgical industries, it is durable, easy to install and low maintenance, serving as a standard dedicated hose assembly for powder pneumatic conveying.

Product Description：

Product Introduction

The coal powder pneumatic conveying working conditions in chemical and metallurgical industries feature high particle hardness, fast flow speed and strong scouring wear. Ordinary hoses are easy to wear thin and perforate after long-term powder conveying, causing powder leakage, material waste and environmental pollution. This wear-resistant sandblasting hose assembly is specially developed for the mixed pneumatic conveying of coal powder and nitrogen, supporting metallurgical smelting and chemical powder transportation equipment. The material and structure are reinforced for excellent wear and scour resistance, fully meeting the high-intensity continuous feeding requirements of heavy industry.

Material and Performance Advantages

The inner hose adopts thickened high wear-resistant rubber to resist long-term high-speed scouring of coal powder particles, with excellent wear resistance, no wear-through, cracking or peeling during long-term use. It adapts to the temperature range of -35℃～+80℃, keeping flexible at low temperature and stable without softening or aging at high temperature. The rated working pressure is 1.6MPa with stable structure, resisting pressure fluctuation and pulse impact, no bulging, delamination or bursting. Perfect for mixed conveying of coal powder and nitrogen, the hose features good airtightness without air leakage or powder backflow, ensuring environmentally friendly and dust-free operation.

Technology and Application Scope

The hose assembly is integrally crimped by CNC precision technology, with firm connection between hose and joints, no loosening or powder leakage under long-term vibration. With good flexibility and small bending radius, it is easy to install and suitable for metallurgical powder conveying pipelines, chemical coal powder transportation and dust pneumatic conveying systems. Featuring wear resistance, aging resistance and low failure rate, it extends replacement cycle, reduces maintenance costs and ensures stable and safe operation of the powder conveying system.
