filter tubes

          Our screen pipe which is used with the deep well submersible pump or water treatment is manufactured in the all-welded continuous slot wedge-wire to support rod construction, with the latest electronically controlled welding system, ensuring greater fusion strength between the profile wedge wire and support rods maintaining accurate slot opening tolerances. The support rod can be triangle wire or echelon wire. The profile wedge wire is triangle too. For the special shape of the profile wedge wire that it make the shape of the slot is v. It is said that the outside space is small than the space of inside. Increase its anti-processing efforts, not easily plug is a professional sand wells screening equipment. Compared with the existing filtering devices it has larger percentage of open area, precision fitting size and high precision filtering. It also has a solid structure, withstand high temperatures and corrosion resistance, good mechanical performance, long service lif.
