Fabrication of Roscoe Moss Company's blank pipe and shutter screen is by the spiral process utilizing double, submerged-arc welding. This method offers special advantages including; accurate geometrical tolerances, increased strength (due to wall thickness reinforcement of the fusion weld), and assurance of full weld penetration of the seam. Shutter screen is made from these high quality tubes.
Sea FloŽ Screen
Roscoe Moss Companys Sea FloŽ Screen employs a louver shaped aperture that increases collapse strength, minimizes plugging, and provides reliable control of sand and filter packs. Another important feature of Sea FloŽ Screen is its smooth, unobstructed interior, which facilitates development, redevelopment, and cleaning.
Sea FloŽ Screen is available in various slot sizes and patterns. Roscoe Moss Company works closely with designers to ensure selection of the most appropriate configuration. Ends of Sea FloŽ Screen are generally prepared for field assembly with factory-attached weld collars. This type of connection provides greater joint strength and economy than other types of fittings. Compared to other welded connections, weld collars are substantially easier and faster to install.
Roscoe Moss Company also manufactures continuous slot screen, sometimes referred to as wedge wire screens. These screens are manufactured by wrapping and resistance welding a shaped wire around an internal array of longitudinal rods. This process lends itself to close tolerances required for very fine aperture sizes; the V-shaped slot configuration minimizes clogging by formation or filter pack particles. Continuous wire wrap screens are designed for production wells where there are a limited number of thin, well defined, and highly-permeable small grained aquifers. Continuous slot screens can be manufactured with very small slot openings and yet maintain the necessary open area to minimize frictional head loss. Roscoe Moss Company continuous slot screens can be manufactured from a variety of corrosion resistant materials.
