Cold Weather Blow-Outs prevent the water discharge tubing of dedicated bladder pumps from freezing. It includes all tubing and necessary fittings. The Blowout consists of a compression coupler that splices into the discharge tube ten feet below the top of the casing. A small diameter tube is attached to the barbed fitting and extends to the well closure where it terminates at a one-way valve.
Cold wire feeders are used for gas tungsten arc welding and plasma arc welding. These are also used in other applications where a controlled feed of wire is required such as a brazing operation. It consists of wire feed head & spool holder, microprocessor controller, and wire guide positioner assembly. Cold wire feeding is used in the welding process to enhance or preserve the metallurgical integrity of the weld metal by selecting the wire type to add the required elements to the weld or to replace those, which are lost as a result of the welding operation.
