Surface FilterSurface Filters are used in coiled tubing applications to prevent debris from clogging the coiled tubing work string tools. If debris is allowed to enter the work string it will be pumped downhole and result in tool string components being plugged up. Use of Surface Filter greatly reduces the risk of tool string malfunction.Use of the surface filter minimizes the tendency to plug small nozzles in the downhole tool string. The surface filter eliminates the possibility for debris passing through the pumping system to enter the coil and potentially clog hardware at the end of the coil that uses small orifices. The filter has a large surface area for high debris-holding capacity. It should includes a bypass burst disc, which ruptures if the filter clogs.The filters are designed to fit into a 2 1502 male union sub. The filters are 1.50 O.D.
