摘要

"well interior connector device, protective splicing device, method for providing a well interior control line, air expansion protection method by weld seam of the weld joint of a welded seam assembly, and air expansion protection method within the weld seam of the weld joint of a welded splice assembly ". The present invention provides a weldable connection at the installation site. In one embodiment, the weldable connection at the installation site consists of an interior well connector device for sealingly coupling a first segment of a control line to a second segment of a control line. The control line has an outer housing within which a secondary housing made of a polymeric material is encapsulated. a communication line runs inside the secondary housing. the connector further comprises a solder welded to the outer housing of the first and second control line segments. For protection of the communication line against thermal radiation and heat generated during the welding process, at least one reflective sleeve replaces a portion of the secondary housing at a location between the communication line and the welds of the connection.
