Mounting arrangement for a pipe base well screen utilizes a weld for joining one end of a cylindrical screen member to the outer surface of an internal pipe member which has perforations along a portion of its length underlying the well screen. The opposite free end of the screen member includes an elongated sleeve portion which supports an internal elastomeric O-ring member in a groove. The O-ring seals the screen member to an unperforated portion of the pipe base and permits the pipe to be subjected to substantial tensile and torsional stresses without destroying the screen as often happens when a screen is welded at each of its ends.
