The slotted pipe is produced using laser cutting technology, the slot is with high precision, good edge verticality, trimming smooth without glitches and etc.

The slotted pipes using in oil exploration can prevent 99%sand,decrease80% of wel heavy repairand increase the oil well’ strengh, integrality and stability of keeping off sand.Meanwhile,the laser incision can make very small scuts 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.
