EP pipe sleeve suitable for centrifugal machine

The EP pipe sleeve suitable for the centrifugal machine comprises a plurality of first pipe sleeves which are connected with one another and a plurality of second pipe sleeves which are connected with one another, the outer diameter of each first pipe sleeve is matched with the inner diameter of a pipe hole of the centrifugal machine, and the outer diameter of each second pipe sleeve is matched with the inner diameter of each first pipe sleeve. The number of the first pipe sleeves is equal to that of the second pipe sleeves, the first pipe sleeves and the second pipe sleeves are in one-to-one correspondence, and the second pipe sleeves are sleeved with the first pipe sleeves. According to the EP pipe sleeve provided by the utility model, a plurality of pipe sleeves are connected with one another, so that repeated operation is avoided, manpower is saved, the cost is reduced, and the working efficiency is greatly improved; meanwhile, the first pipe sleeve and the second pipe sleeve which are connected in a slee
