Screen pipe

Screen pipe

Screen pipe

Screen pipes are steel tubes in which holes are machined on the tube outer surface in order to extract oil, gas, etc. JFE Tubic produces screen pipes with the customer's specified hole shape and open area ratio.
By using a state-of-the-art laser beam machine, it is possible to manufacture long strainer pipes with a maximum length of 12 m.
Both slit-type and hole-type are available. Please consult with JFE Tubic regarding specific hole shape, number of holes, and open area ratio requirements.

  • Drop-weight impact tests
    (vertical, inclined 45°, side)
