摘要： A sizing sleeve for controlling the diameter of plastic tube includes pressurised sizing sleeve portions (10) in which fluid is injected under pressure about the tube circumference to form a lubricating layer. Drainage zones (12) axially separate and isolate adjacent pressurised portions to allow independent temperature and pressure control. Each pressurised portion has flow stabilizing means (28) reducing variations in flow responsive to changes in the lubricating layer pressure. The stabilising means may comprise a high pressure fluid source and high pressure drop constriction means comprising fine apertures (56), which may be formed as grooves milled into end surface of abutting sizing sleeve segments (30).

摘要： The invention provides, in a first form, an expandable plug for regulating pressure or flow within a tube. The plug has an inflatable bladder (12) for diametral expansion by internal fluid pressure introduced by inlet (14). The plug is reinforced by an envelope (26) of cords (28) which spread laterally upon inflation of the bladder to provide diametral support to the bladder. In a second form of the invention, an inflatable plug positioned in a tube of internal diameter d is controlled according to the equation Pp = DELTA P + Pd wherein Pd is the internal pressure in the plug, DELTA P is the differential pressure across the plug and Pd is the plug free expansion pressure for diameter d.

摘要： A method of expanding a tube of plastics material is disclosed i n which a longitudinally travelling tube (10) is progressively diametrically expanded by internal fluid pressure in an expansion zone (20) between an upstream plug (24) and an expandable downstream plug (26). Expansion of the tube is controlled in response to parameters which directly or indirectly indicate variation in the relative velocity at which material is delivered to and removed from the expansion zone, such as detecting upstream tube velocity (38), early expansion diameter (36), axial force (39) on a sizing device (28) or the tube diameter (41) just before the expansion zone.

摘要： A method of producing a thermoplastics material pipe having a wall which is drawn or stretched to achieve material orientation. The method includes the steps of continuously effecting an intial extrusion of a tube (3), temperature conditioning to a desired orientation temperature, expanding the tube by pressure within an internal pressure region (18) and cooling. In one form of the invention, the internal pressure region is limited at its downstream end by an expandable plug (8). In another form of the invention, the extruded tube is brought to the desired orientation temperature by cooling the outer surface of the wall to below the desired temperature, subsequently heating the outer surface of the tube wall and then temperature conditioning the tube wall.
