In December, our company provided high quality laser slot liner pipes for a well drilling project in Ethiopia. Our slotted pipes use laser cutting equipment to cut slots with different arrangements. The laser-cut slots are with the same size, uniform arrangement and without burrs. The slot width is 0.2-0.5mm and the slot opening rate is 9%, the laser slot liner screen is very popular in the market. https://www.nayushiye.com/products/well-screen-and-steel-casing/slotted-liner-pipe.html
