摘要:
A method of coupling tubular bodies (12A,14A) is provided, particularly for use in fluid handling systems requiring a fluid-tight, pressurized joint. One tubular body (12A) is made from a polymer. The other tubular body (14A) is formed as a laminate having a metallic layer (34) and a polymeric layer (36) (e.g., nylon coated aluminum tubing). The tubular bodies (12A,14A) are positioned relative to one another (e.g., the laminated tubular body (14A) may be inserted within the polymeric tubular body (12A) when the polymeric layer (36) of the laminated tubular body (14A) is outward of the metallic layer (34). The tubular bodies (12A,14A) are then joined together by induction welding to cause heat transfer from the laminated tubular body's (14A) metallic layer (34) to its polymeric layer (36) thereby resulting in deformation of the polymeric layer (36) and bonding of the polymeric layer (36) to a surface of the polymeric tubular body (12A), forming the joint (68).
摘要:
A two part heat and moisture resistant acrylic adhesive composition is provided and includes an initiator part comprising at least one polymer dissolved in a (meth)acrylate monomer and a free radical initiator and an activator part comprising at least one polymer dissolved in a (meth)acrylate monomer, a pyridinic reducing agent, an organometallic curing promoter and a thiourea accelerator.
摘要:
The invention relates to a hand-held device (1, 100) for the transverse welding of plastic tubes. The hand-held device (1, 100) comprises a welding device for the transverse welding of a tube (2) and a separating device for completely separating the transverse-welded tube (2) on the transverse welding.

摘要:
A tubular assembly comprising a hollow elongated tube 11 having an internal cross section with an inside surface, a proximal end and a distal end defining a bore around a longitudinal axis and a part 12 mounted within the bore so that it is at least partially within the tube 11, the part having been thermally treated to expand and engage the inside surface of the tube and thereby from a fluid tight seal. A method and apparatus for making such a tubular assembly is also disclosed.
