Sandblasting pipe It is also called rubber hose for sand and grit blasting. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction.
below Sandblasting pipe The manufacturer will introduce the types and product performance of sandblasting pipes.
1、 Sand blasting pipe type:
Type A electrical connection, marked with "M";
Type B with conductive rubber layer, marked with "Ω";
Type C non-conductive ordinary type, marked with "A";
2、 Product performance of sandblasting pipe:
2. Conductivity
Each "M" grade hose shall not exceed 10² Ω。 Each "Ω" rubber hose shall not exceed 1M Ω.
Wear resistance
As Sandblasting hose Its main performance is also the main judgment basis for users to distinguish the quality of rubber hose. The current industry standard HG/T2192-2008 stipulates that the wear volume shall not exceed 140mm³ according to method A of ISO 4649;. (The test method used in the previous old version of the industry standard is: Akron abrasion method - the wear volume is not more than 0.8cm³/1.61km. Although this method has been replaced by method A of ISO 4649 since 2008, some domestic hose users still use this method.)
3. Other performance
Other properties, such as interlayer bonding strength, ozone resistance, mechanical properties under verification pressure, are also indicators to consider the quality of sandblasting pipes. For details, please refer to the current industry standard HG/T2192-2008 for sandblasting pipes.
1. Bending performance
When the hose is tested with the minimum bending radius of 10 times the nominal inner diameter at 23 ℃, the deformation KD value shall not exceed 0.8 times the outer diameter D of the hose. (K is the ratio of the outer diameter before bending minus the outer diameter after bending to the outer diameter before bending.) (- 25 ± 2 ℃), there should be no cracks after bending.
The above is Sandblasting pipe manufactor I hope I can help you with the hose related knowledge explained by my editor!
