4-Ply Blast Hose
4-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 OperationTongbao 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.
