Sand blast hose

Sand blast hose 4-Ply Blast Hose4-ply blast hose is used in industrial settings where external scuffing and occasional light vehicle traffic is expected. It can be used with all common blast media.Description of Operation Tongbao 4-ply blast hose accepts properly sized blast couplings and nozzle holders. The coupled hose can attach to any blast machine fitted with quick coupling connections. 4-ply hose is widely used in shipyards and railyards because it stands up to external abrasions from being dragged about the blast site. The tough outer casing of 4-ply blast hose can even withstand occasional light vehicle traffic without collapsing. For applications where 4-ply blast hoses are used (for their more durable outer casing), a 10- to 15-foot length of Tongbao hose can be connected as the last section before the nozzle. This whip hose is easier for the operator to bend and maneuver.Advantages 4-ply hose has a durable outer casing compared to 2-braid and Tongbao hose Inner tube wall of 1/4-inch thick SBR rubber treated with static-dissipating compound Four-layer outer casing of cloth and rubber-impregnated fiber winding Casing is pin-pricked to prevent formation of air pockets between layers
