The present invention is directed to a pipe section ( 220 ) and a connector ( 400 ) that are adapted to be welded together, wherein each of the pipe and connector have inner and outer beveled surfaces and the joint is comprised of an angular alignment land ( 60 ). In one embodiment, an outer beveled surface on the pipe and an inner beveled surface on the connector cooperate to define the angular alignment land ( 60 ). In yet another illustrative embodiment, the inner beveled surface of the connector and the outer beveled surface of the pipe have a bevel angle of approximately 30 degrees, while the outer beveled surface of the connector and the inner beveled surface of the pipe have a beveled angle of approximately 45 degrees.
