Laterials

These assemblies consist of a series of screen laterals connected to either a central header pipe or a hub. They are designed for effective media retention in a wide range of applications, including ion exchangers, clay and sand filtration applications and carbon towers.

Inline Strainer

A resin trap is a safety device used on the overflow lines of ion exchange units, high-purity water systems and activated carbon and media filters.

Filter Nozzles

Nozzles are used in liquid/solid or gas/solid separation. Their design and quantity will vary depending on application and customer-flow requirements. Nozzles allow a more effective use of the treatment media.

Water Well Screens Welding Ring

When you need to successfully finish an environmental drilling job, BT water well screen is an irreplaceable choice. It can efficiently prevent the unneeded sands from entering the well, while achieving higher productive efficiency and longer using life of the well.

Water Well Screen Threaded Connection

Radial External Wire

These tubes are composed of a surface profile wire that is spirally wrapped around axial support wires and attached to each other by resistance welding.

Screw Press Separator

For dewatering using a screw press, we can provide a screen designed to meet your exact specifications.

Flattened Slot Tube

Depending on the required specifications, BTOSLOT can also opt to produce from a slot tube. Subsequently the tube is split open, flattened and cut to the required size.

Radial Internal Wire

For these type of slot tubes, the support wires are on the outside in an axial direction and the profile wire runs radially on the inside of the tube. The flat side of the profile wire is oriented to the inside of the tube.

  • Commodity name: Radial Internal Wire
  • Product Description
  • Radial Internal Wire

    For these type of slot tubes, the support wires are on the outside in an axial direction and the profile wire runs radially on the inside of the tube. The flat side of the profile wire is oriented to the inside of the tube.

    This type of filter tube is made starting from a slot tube with radial external wire that is cut open in the longitudinal direction.  Upon flattening the tube, it is then rolled ‘inside out’ so the support wires are now on the outside of the tube. The support rods are welded together on the outside which results in a welding seam.

    When a scraper blade is used, it is required that the supports are on the outside. Slot tubes with a radial internal wire is an excellent solution for this.

    The minimum diameter is 100 mm depending on profile, length and material. Maximum diameter is unlimited.

    Just like slot tubes with radial external wire, end pieces can be welded to the tubes.

Better in every way

Wedge wire, also known as profile wire or V-wire, can be configured to a variety of forms, sizes, and open areas. The result is a very strong product with a smooth surface that is resistant to clogging. This makes wedge wire advantageous for a diverse range of applications that require screening, filtering, dewatering, sizing, drying or cleaning. 

Better in every way

Compared to wire mesh and perforated metal, Wedge Wire’s continuous slots have more open area. Their consistent slots are more durable and virtually non-clogging to reduce media abrasion.

Designed and manufactured

Our grids have great design flexibility and are constructed in a wide variety of shapes and sizes and from a variety of corrosion-resistant alloys. Specific processes and vessel requirements can be accommodated. For available corrosion-resistant materials, see material list.

Benefits of our support grids include:

(a)Continuous-slot design provides an increased open area .

(b)The continuous slot formed by V-shaped surface wires ensures a two-point contact between the particles and the slot to minimize clogging.

(c)Wide range of profile wires are available to suit most applications.

(d)High-precision slot sizes are available to meet your requirements.

(e)V-shaped surface wires allow for easy cleaning.

(f)Very low pressure drop.

(g)Additional supports are utilized to accommodate extreme load conditions.

(h)Low maintenance.
