Abstract: The nonmetal thickwall pressure pipe mentioned is a new type of wire longitudinal enhanced and high elasticity polymer material pipe， 4.0～8.0 MPa water or air pressure is injected. Under the outside elasticity constrain, internal pressure injected and elastic deformation analyses are made approximately to meet engineering demand. The normal pressure produced by the outside elasticity constrain is simplified to be homogeneous distribution, the pipe is simplified to be round cylinder, by means of pressure tunnel theory. The injected internal pressure, squeezing pressure, tubular radial and ring deformation are analyzed. The analytical method and calculation formula lay the engineering application foundation for the nonmetal thick-wall pressure pipe.
