In order to solve the principal problem on the transportation of agricultural products, the new technique of transporting agricultural products-the piped hydraulic transportation of tube-contained raw material was put forward. The technique did not only overcome the disadvantages of high cost and inefficiency, but also had the advantages of no pollution and no terrain restriction. Some hydraulic characteristics of the piped hydraulic transportation of tube-contained raw material under the different loads were researched on the piped carriage. The results showed the linear relationship between the load and the average velocity of the piped carriage was inversely proportional. Additionally, it was discovered that the fluidal pressure change of each cross section has been closely connected with the load of the piped carriage. 
