Name: High pressure hose
1. High-pressure hose structure: inner rubber layer, inner rubber protective layer, medium rubber layer, wire winding layer and outer rubber layer.
Second, use: steel wire winding drilling hose for oil field cementing, workover and petroleum geological exploration, small drilling rig and water conservancy coal mining, conveying mud and normal temperature water and other fluid media. Layer 2 technical performance indicators:
