Stabilizing restraint for catalyst loading tubes

A method, comprising:

• attaching a first restraint having at least one first collar portion to a first tube segment by a first and a second fasteners, respectively, and attaching a second restraint having a at least one second collar portion to a second tube segment by a third and a fourth fasteners, respectively;
• joint coupling the first tube segment and the second tube segment;
• aligning the first restraint and the second restraint;
• passing a first end of a first linkage through a first end of the at least one first collar portion;
• passing a first end of a second linkage through a second end of the at least one first collar portion;
• passing a second end of the first linkage through a first end of the at least one second collar portion;
• and
• passing a second end of the second linkage through a second end of the at least one second collar portion.

A restraint system, comprising:

• a first restraint having a first collar portion and a second collar portion;
• a first fastener configured to attach the first collar portion to a first tube segment;
• a first linkage having a first end and a second end, wherein the first end of the first linkage couples to a first end of the first collar portion and a first end of the second collar portion;
• a second linkage having a first end and a second end, wherein the first end of the second linkage couples to a second end of the first collar portion and a second end of the second collar portion;
• a second restraint having a third collar portion and a fourth collar portion;
• a second fastener configured to attach the third collar portion to a second tube segment;
• wherein the second end of the first linkage couples to a first end of the third collar portion and a first end of the fourth collar portion;
• and
• wherein the second end of the second linkage couples to a second end of the third collar portion and a second end of the fourth collar portion.
