The slotted pipes using in oil exploration can prevent 99% sand, decrease 80% of oil well heavy repair and increase the oil well's strength, integrality and stability of keeping off sand. 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 0.10-0.5 mm in the tube wall.
The slotted liner is a robust and cost-effective solution for long completions or low productivity wells.
We offer straight and key stone slot in a wide range of slotting patters to satisfy the required open area.
High rigidity resisting scrape and abrasion, high intensity, anti-corrosion and even distribution.

The perforated pipe with cutting edge technology, which is manufactured carbon steel or stainless steel, used for the application of oil reservation layer without much sand or for application of prevents the rock bits dropping off the well bore.
Every joint perforated by us is deburred internally and externally.
Each hole is visually inspected and burr cleaned.
