Slotted casings pipe are widely used for oil filters, they can
filter out 99% of the sand, which greatly reduces the maintenance
rate of the tube, and also improve the tube’s strength,
integrality and stability of keeping off the sand.The slotted
casings are produced using laser cutting technology, the slot is
with high precision, good edge verticality, trimming smooth
without glitches and etc.
Meanwhile, the laser incision can make very small cuts with
smooth surface and high precision. Although its structure is
simple, it is very effective. It has small cuts of 0.1-0.5mm in
the tube wall.
