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 worlds 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
