Product Details

Wedge wire filter pipe, also known as Johnson pipe, Johnson sieve pipe, stainless steel sieve pipe, is widely used in oil, gas, water wells and sand control in the world, and it is especially important in chemical and environmental protection industries. It is one of the most widely used filter sieve tubes used in various oil, water resources recycling and resin collection materials.

The wedge wire filter screen adopts the world's most advanced full-wound welding production process, and the special T-shaped wire is wound and welded on a group of support wires arranged in a circle. Full-process welding guarantees the strict and continuous integrity of the product, so that it forms the ideal gap size, and has the maximum capacity to withstand high pressure.

Due to the use of full-program welding, not only the strict continuous integrity of the product is guaranteed, but also the ideal gap size is formed. Compared with the welding process currently widely used in China, the full-welded wedge-shaped wire winding screen has the characteristics of smooth pipe surface, no production edges, no burrs, and uniform gaps without leaking grease.


Material: stainless steel wedge wire or custom.

Surface profile: triangle wire.

Support profile: triangle wire, round bar, and wedge wire.

Slot size: 0.05 mm - 35 mm

Cylinder diameter: 10 mm - 1200 mm

Application: mine, coal, mineral and other application

Reverse formed wedge wire screen pipe (internal circumferential wire with external axial support rods) is a kind of strainers that flow from inside to outside filtration, with smooth working surface inside. This type wedge wire screen pipe is manufactured by wrapping and welding stainless steel V-shaped profile wire cylindrically around support rods under automatic specialized wedge wire screen machine, then be made to screen pipe through cutting, reverse rolled, welded processing.

For special areas of application (among others, the starch industry) screen cylinders can of course also be manufactured in looped finish. Adjoining is an example of two end flanges. In this case, as well, almost all requirements by our customers can be realized after corresponding technical clarification.

UBOW can offer reverse formed wedge wire screen pipe in the standard specifications, the slot size from 0.2 mm to 1 mm, while pipe diameter from 100 mm to 914 mm, and manufacture pipe length is up to 3 m, the wedge wire screen pipe is commonly constructed with materials of grade 304 (1.4301) stainless steel.


To improve the stability and high strength of the wedge wire screen cylinder, you can do some reinforcement as follow:

Wedge Wire Filter Tube/Pipe advantages:

1. The application of wedge wire on the filter element forms a V-shaped opening between the gaps of the screen tube. Due to the inherent advantages of the design, it can operate more efficiently than other types of filtration products, not only ensuring the smoothness of water resource filtration, but also
