Thermal Stress Calculation of Steel Pipe Laid on Land

With the problems of self-compensating capability and thermal stress for those non 90° bends of large radius of curvature laid on land, the author uses the method of mechanics to do theoretical analysis and puts forward the formula of calculating elasticity on pipe support and the calculation method of those unknown quantity. The article also explains the steps of calculating the maximum thermal stress on pipe support with combination of calculation examples.
