Application

Sand control screens can resolve problems of sand production and pulverized coal.

Types

There are laser slotted screens and wire wrapped screens.The design and manufacture of wire wrapped screens conform to SY/T 5182 Welded stainless steel wire wrapped screen

Working principle

The slotting width & length of the laser slotted screen and the wrapping gap & screen length of metal wrapped screen are determined according to the volume of sand  and pulverized coal , as well as the particle size.

The laser slotting screen and the wire rapped screen have the same working principle. It is to avoid sand plug and sand burial of subsurface pumps by isolating the sand and pulverized coal with bigger diameter than the slotting width or wrapping gap outside the screen.
