Product Description
The wedge wire support grating all called Johnson type support grid, it is assembled by welding a V-shaped mesh screen with a support plate.
The material is usually stainless steel 304/316 or chromium-molybdenum alloy steel, resistant to high temperatures and hydrogen corrosion, has a sturdy structure,
precise mesh size and a high porosity, and is easy to backwash, thus having a longer service life.
The structure of the support grid is generally multi-layer and composed of multiple pieces, which is convenient for maintenance and replacement.
It usually works at a temperature range of 200-450°C. The grid needs to bear the weight of the catalyst bed and prevent particles from entering the downstream.
Through the opening structure of the grid, hydrogen and raw materials can pass through the catalyst bed layer evenly.
The grid structure can also ensure a large radial area and sufficient strength.
Application
The wedge wire support grating is one of the important components in petroleum refining equipment.
Due to its wide application in hydrogenation reactors, it is also known as the catalyst support grid, the support grating produced by us can adapt to various types of reactors and the various harsh working conditions of the internals in towers.
