Abstract
A hose structure of simplified construction suitable for rigorous high pressure applications such as rotary well-drilling apparatus is described. The hose includes a heavy-walled tube of elastomeric material having a measured stress of at least 600 psi at 20 percent elongation, an elongation at rupture of at least 150 percent and a Young's modulus of at least 2000 psi. The formulation of the tube material includes a reactive resin system capable of polymerizing in situ.
