Material: carbon steel, stainless steel Pipe
categories: oil casing, tubing;
Length (single) : 15 m or less;
Pipe diameter: 50 to 500 mm (length of 15 m or less)
Wall thickness: 20 mm or less;
Slot width (0.10 ~ 4) mm + / - 0.03 mm;
The slot layout: parallel, crisscross, spiral
The slots can be straight or keystone shaped. The keystone slot is narrower on the outside surface of the pipe than
on the inside. Slots formed in this way have an inverted “V” cross-sectional area and are less prone to plugging because
any particle passing through the slot at the outside diameter (OD) of the pipe will continue to flow through, rather than
lodging within the slot. While the slotted liners are usually less costly than wire-wrapped screens, they have smaller inflow
areas and experience higher pressure drops during production.
Slotted liners also plug more readily than screens;
they are used where well productivity is small and economics cannot support the use of screens.
it is using special ultra-thin cutting plate and beam cutting , the slot width is 0.2 to 0.5 mm.
Seam cross section is rectangular, trapezoidal (trapezoid Angle of 3-8 degrees) and form (hole) and so on ,
there are many kinds of form, could guarantee permeability is 0.5% - 10%, the arrangement of aperture
according to user requirements for processing.
