Double containment pipe support retainer

A containment pipe fitting subassembly comprising:

• a containment fitting having open end sockets of a radius to slidingly receive ends of containment pipes;
• a carrier fitting having open end sockets of a radius to slidingly receive ends of carrier pipes, said carrier fitting being inside said containment fitting;
• a pair of alignment supports radially between respective ones of said containment fitting sockets and said carrier fitting sockets;
• each said support having a peripheral flange with a radius comparable in size to the radius of said containment fitting socket and fitted therewithin;
• said flange defining a central orifice having a diameter comparable in size to the inner diameter of said carrier fitting socket;
• and
• each said support also having an axially extending cylindrical sleeve with an inner diameter comparable in size to the outer diameter of said carrier socket and said sleeve being fitted over said carrier socket.

A pair of alignment supports for fitting between containment fitting end sockets and carrier fitting end sockets of a containment pipe assembly;

• each said support having a peripheral flange with a radius comparable in size to the inner radius of a containment fitting socket;
• said flange defining a central orifice having a diameter comparable in size to the outer diameter of a carrier pipe and to the inner diameter of a carrier fitting socket;
• and
• each said support also having an axially extending cylindrical sleeve with an inner diameter comparable in size to the outer diameter of a carrier socket, said sleeve to be fitted over the carrier socket.
