The base pipe, casing or tubing, is selected to API specifications by size, grade and weight for each of your required applications.We produce the proven slip-on type of pipe base screen. Our slip-on type of pipe base screen is manufactured from two components: the base pipe and the slip-on screen. The base pipe, casing or tubing, is selected to API specifications by size, grade and weight for each of your required applications. See Table 3, for our standard range. The base pipe will then be perforated with a series of holes drilled to a pre-determined quantity and pattern, see Table 3 above, to carefully balance flow-capacity at each end for both down-hole handling.The holes are then debarred and the joint cleaned, inspected and treated to give the base pipe a long shelf life. |
