2019-10-17  Besides the first method, in other methods like the Dry cast method, packer head method, the tamp entail method, pipe making machine uses a dry concrete mix and manufactures the desired concrete pipes through the standard technique of press rolling. Another method, Wet casting method, machines for making concrete pipes use a high slump of wet cast concrete mix and it is highly recommended for making huge diameter pipes.

Process for the manufacture of concrete pipes -

A process for manufacturing concrete pipes or the like by centrifugal casting comprising the steps of casting an outer layer in a rotary mold, inserting a metal cylinder, split longitudinally in at least one place within said outer layer, inserting a second metal cylinder split longitudinally in at least one place within said first mentioned cylinder in such a manner that the slits are offset relative to one another, whereby said slits will be covered, spinning the mold to expand the
