Abstract: Described herein is a method for joining a first metal pipe with a second metal pipe, the pipes being joined together in an overlapping area by use of a two-component polyurethane adhesive that encapsulates the overlapping area, where the method includes the steps of:
(1) applying the two-component polyurethane adhesive onto an inner surface of a fixture; (2) inserting one end of the first metal pipe into one end of the second metal pipe so as to form a pipe assembly having the overlapping area between the two ends, and putting the overlapping area of the pipe assembly into the fixture; (3) closing the fixture such that the overlapping area of the pipe assembly is fixed in the fixture, and such that the adhesive therein encapsulates the overlapping area of the pipe assembly; (4) curing the two-component polyurethane adhesive; and (5) optionally, removing the fixture from the pipe assembly.

Abstract: Described herein is a method for preparing polyurethane foams, including (1) placing a reaction mixture into a pressurizable chamber, and (2) polymerizing the reaction mixture at an additional pressure, where the reaction mixture comprises an isocyanate, an isocyanate-reactive compound and a blowing agent, and the reaction mixture is placed into the pressurizable chamber at a packing factor of 2.0-4.0. Also described herein is a polyurethane foam prepared by such a method.
