摘要： The invention relates to a method and a device for cooling an extruded thermoplastics pipe (1) by directing a gaseous cooling medium tangentially towards the inner surface of the thermoplastics pipe (1) along its whole periphery, whereby the interior of the thermoplastics pipe (1) is divided by means of a protecting pipe (8) into an outer ring-shaped flow channel (9) for the cooling medium along the inner surface of the thermoplastics pipe (1), and a central return channel (10) through which a part of the cooling medium is intended to be sucked back influenced by the flow of cooling medium in the outer ring-shaped flow channel (9), and to be redirected towards the inner surface of the thermoplastics pipe (1). The invention is characterized in that the cooling medium is air, and that there is a cooling equipment (6) mounted in the return channel (10), whereby temperature and flow rate at least of the cooling water led to the cooling equipment (6) and possibly also of the cooling air which is fed into the thermoplastics pipe (1) are adjusted and controlled based on dimension and extrusion rate of the thermoplastics pipe (1) being manufactured.

摘要： The invention concerns a method for manufacturing pipes coated with a peelable protection layer, wherein the core pipe (1) is produced by extruding and calibrating, after which the surface of core pipe (1) is heated before a protecting coating layer (7a) is applied onto the core pipe (1) on passing through a coating die (7) , followed by cooling the applied coating layer (7a) before the readily coated pipe (9) is drawn out of the process. The method is characterized in that the degree of adhesion between core pipe (1) and coating layer (7a) is controlled by rapid and effective heating of the surface of the core pipe (1) to a predetermined temperature and by controlling welding time and stretching of the coating layer being applied onto the core pipe (1) by maintaining a controlled vacuum level inside the coating die (7) forcing the coating layer to hit the surface of the core pipe at an angle as steep as possibly, preferably between 45 and 90 degrees, most preferably between 60 and

摘要： This invention relates to a method for joining thermoplastic pipes (1) made by spiral winding a hollow profile (2) with mainly rectangular cross section. The method is characterized by the following stages: cutting the profile (2) in the end of the pipe along the inside of the side wall that is fastened to the nearest preceding wound round and with a cut (3) cutting the end of the profile in a right or obtuse angle (α), of equal size for all pipe ends to be joined together; closing the hole in the cut ends (3) of the profile, and preparing the end surfaces of the pipes along their entire peripheries; positioning two pipes (1) aligned to each other so that the cut profile ends (3) are axially offset; inserting a welding ring (5), matching with the inner and outer diameters of the pipes, between the two pipes (1); which welding ring comprises at least one loop of resistance of wire (8) covered by a thermoplastic sleeve (7); aligning the two pipes (1) with an inner root support (8) and an outer root support (9) around the seam with the welding ring (5); pressing the pipe ends together against each other; connecting the resistance wire (6) of the welding ring to a current source (12) to heat the thermoplastic material in the welding ring (5) and in the pipe ends so that the thermoplastic material melts down and forms a welding seam, cooling the welding seam; removing the root supports (8, 9) and other accessories (10, 11) from the pipe welded together, and cutting off the connecting wires (13) of the welding ring.
