English
Wear-resistant hose is a kind of material conveying pipe, mainly used for particles, gravel, cement, sand, concrete, gypsum and other solid particles containing liquid conveying, suitable for all kinds of tunnel engineering, tunnels, caves and other engineering operations.
It is usually used in the use environment such as ship sandblasting and flowing sand operation; The common inner adhesive is made of wear-resistant NBR (natural rubber) material, and the outer adhesive is packaged with composite adhesive.
The sandblasting pipe is generally divided into light sandblasting pipe and heavy sandblasting pipe according to the working condition and the loss degree of the material particles to the conveying medium, and the spiral steel wire will make it suitable for negative pressure environment
The general working pressure is within 12 bar, the higher blasting pressure can reach 36 bar, and sometimes the vacuum negative pressure parameters such as 0.8 bar to 0.9 bar are required.
Temperature The common temperature ranges from -30℃ to +80℃
Wear coefficient Common wear coefficient of 60~75 cubic mm
