摘要:
An elastomeric flexible hose for the transportation of high pressure and/or temperature hydrocarbon liquids or gases comprising: a semi-crystalline thermoplastic inner liner layer (1'); an armour layer (9') surrounding the inner liner layer (1') at an end of the flexible hose; a hose coupling (13') disposed at the end of the hose and surrounding the armour layer (9'); a sealing area defined by recessed portion (3') of the hose coupling (13'); and a semi-crystalline thermoplastic sealing material (23), or a cross-linked elastomeric sealing material, disposed in the sealing area; wherein a portion of the inner liner layer (1') at said hose end extends into the sealing area and is bonded to the sealing material (23), and wherein a reinforcement material (2') is provided wholly within the inner liner layer (1') and further in that the inner liner layer (1') is bonded to the inner surface of the hose coupling (13') by a tie layer (14').

摘要:
Method and apparatus for welding two container walls of plastic film (1, 2) to a plastic tube (3) having a substantially circular cross section, wherein the plastic tube (3) is arranged between two parallelly arranged plastic films (1, 2). The two plastic films (1, 2) are made to extend along the outer surface of the plastic tube (3) and to abut each other along a joint face (7) between two welding jaws (5, 6) in an area (8) adjoining the plastic tube (3). The plastic films (1, 2) are welded by means of welding jaws (5, 6) to the outer face of the plastic tube (3) and welded together in the area (8) adjoining the plastic tube (3). The plastic tube (3) is deformed during welding by means of a compressive force applied by the welding jaws (5, (5) to provide the outer surface of the plastic tube (3) with a substantially plane portion (9) extending on both sides of the joint face (7) and substantially perpendicular thereto.
摘要:
Apparatus for welding a reinforcing member to a bag like member comprising a hollow mandrel (18), the hollow mandrel (18) having an outer surface with the groove (17) shaped to the form of the reinforcing member, means (19) for applying a closed end of the bag like member into the hollow mandrel (18) and an open end of the bag like member over the hollow mandrel (18) at the outer surface with the groove (17), the reinforcing member being located with respect to the bag like member at the position of the groove (17) and means for welding (51) the reinforcing member to the bag like member.
