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
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
