A coupling arrangement (100) for connecting thermally insulated, fluid-conducting lines (102, 104) has a coupling (101) comprising a first coupling part (106) and a second coupling part (108), and connecting means (110) for connecting the two coupling parts (106, 108). A covering (112) surrounding the coupling (101) is provided, which covering, on both sides of the coupling (101), in each case lies against the thermal insulation of the fluid-conducting lines (102, 104). A cavity (114) formed by the covering (112) is configured for thermal insulation between the coupling (101) and the exterior of the covering (112).

A flexible pipe joint has a body and an annular elastomeric flexible element flexibly coupling an extension pipe to the body and operable to pivot the extension pipe with respect to the body. The flexible pipe joint also has an annular flexible boot operable to thermally or chemically insulating the annular elastomeric flexible element from the fluid flowing through a lumen of the flexible pipe joint. The annular flexible boot encircles the lumen, and the annular flexible boot has a first annular end attached to the extension pipe and a second annular end mounted so that pivoting of the extension pipe with respect to the body causes a flexing of the annular flexible boot, and a majority of the annular flexible boot has a shape conforming to shape of neighboring components of the flexible pipe joint.

An encasement for heat transfer fluid (HTF) conduits having an outer layer (1) of sheet metal and an intermediate layer (2) below the outer layer (1). The intermediate layer (2) is made of insulating material having a maximum thickness of 1.4 inches (35 mm). The heat transfer fluid (HTF) conduits are movable.
