304 316 johnson screen oil sieve tube  Brief Introduction:

It is manufactured by a v or wedge shaped wire around an internal array of longitudinal supportrods. Each intersecting point of these wire is fusion welded.
The v or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening, hence the screen allows water (oil) to enter your well freely in ample quantities,
while at the same time keeps the majority of sand and gravel out of the well.
