OIL SLOTTED CASING PIPE LASER CUTTING MACHINE
Slotted Liner
Oil slotting pipe is the key part to protect from sand during oil mining. Oil slotting pipe can be classified into five types: bridge type oil slotting pipe, drilling slotting pipe, kerf slotting pipe, composted pipe, wire-wrapped slotting pipe. Oil slotted casing pipe is cut by specialized ultra-thin cutting disk and laser beam. There are many certain configurations kerfs with shape of longitudinal or helical straight line on oil slotted casing pipe. Farley Laserlab oil slotting pipe laser cutting machine adopts advanced technology, which can cut different type of oil slotting pipe. By means of focusing, high density and high-power laser beam working on sieve pipe, on the premise of exceeding a threshold value of laser power density, heat energy from working gas and laser beam’s chemical reaction is absorbed by material, thus causing a dramatic increase in the temperature of laser sport on the surface of the casing, partial melting or gasification of workpiece material to form a hole, then relative motion of the casing and laser beam can achieve casing cutting.

FARLEY LASERLAB oil slotted casing pipe laser cutting machine adopts advanced technology, which can cut different type of oil slotting pipe. By means of focusing, high density and high-power laser beam working on sieve pipe, on the premise of exceeding a threshold value of laser power density, heat energy from working gas and laser beam's chemical reaction is absorbed by material, thus causing a dramatic increase in the temperature of laser spot on the surfacfe of the casing, partial melting or gasification of workpiece material to form a hole, then relative motion of the casing and laser beam can achieve casing cutting.

 

 

Mechanical Motion System

  • Cantilever structure technology (patent number: ZL200520099443.7)provides open operation platform with one-time processing area of 12m x 1.5m
  • Machine tool structure is composed of a bed, cantilever beam, special clamp for sieve pipe cutting, high precision ball screw lubrication device
  • Customized cutting rotation axis, double chuck structure and variable pitch worm can fix sieve pipe more stable and much easier to cut oil pipe. Plane working table can also be equipped to cut plates.

 

 

Features

  • The slotted liner is a robust and cost-effective solution for long completions or low productivity wells
  • We offer straight and keystone slot in a wide range of slotting patterns to satisfy the required open area
  • High rigidity, resisting scrape and abrasion, high intensity, anti-corrosion and even distribution

 

 

Rotation Axis

  • support position adjusted according to the pipe diameter
  • max.pipe length:12m;max.pipe diameter:240mm
  • rotating clamp adopt double chuck structure to avoid the pipe not being vertical and thermal deformation in processing
  • varying pitch worm gear is adopted to effectively achieve mechanical wear compensation

 

 

Cutting Head And Nozzle

  • Customized bifocal laser head(5’’ and 7.5’’), convenient to change to cut material of different depth
  • Laser head can detect pipe on-contact before cutting and automatically position when cutting to match position change
  • Anti-collision all-around auto reset cutting head
