Pipe connector assembly

A method of coupling a first pipe section to a second pipe section utilizing a pipe connector assembly, said pipe connector assembly having a first coupling member comprising a flange, a substantially cylindrical pipe engaging portion extending from a first surface of the flange and a spherical convex seat portion extending from a second surface of the flange, and a second coupling member comprising a flange having a spherical concave seat portion for receiving the convex seat portion of the first coupling member and a substantially cylindrical pipe engaging portion extending from a first surface of the second coupling member flange, the first coupling member flange comprising at least one stud bore extending therethrough and the second coupling member flange comprising at least one stud bore extending therethrough, the stud bores configured to be elongate in an azimuthal direction, said method comprising:

• welding the first pipe section to the first coupling member;
• welding the second pipe section to the second coupling member;
• and
• coupling the first coupling member to the second coupling member.

A replacement core spray line, comprising:

• a first pipe section;
• a second pipe section;
• and
• a first pipe connector assembly coupling said first pipe section to said second pipe section, said first pipe connector assembly comprising a first coupling member comprising a flange, a substantially cylindrical pipe engaging portion extending from a flange first surface, and a convex spherical seat portion extending from a flange second surface, said first pipe connector assembly further comprising a second coupling member comprising a flange having a concave spherical seat portion for receiving said convex spherical seat portion of said first coupling member and a substantially cylindrical pipe engaging portion extending from a first surface of said second coupling member, said first coupling member pipe engaging portion configured to engage said first pipe section, said second coupling member pipe engaging portion configured to engage said second pipe section, said second coupling member concave spherical seat portion configured to seat on said first coupling member convex spherical seat portion, said first coupling member flange further comprising at least one stud bore extending therethrough, and said second coupling member flange further comprising at least one stud bore extending therethrough, said stud bores configured to be elongate in an azimuthal direction.
