Abstract
Ledningsrør og fremgangsmåte for fremstilling av sådanne rør.Pipelines and methods of making such pipes.
Description
Foreliggende oppfinnelse angår ledningsrør og gjelder særlig plastrør for anvendelse ved tilførselstjenester og andre lednings-føringer i bygninger og industri. Rørledninger av plast er lettere å installere enn metallrør, samt er korrosjonsbestandige, The present invention relates to conduits and applies in particular to plastic conduits for use in supply services and other conduits in buildings and industry. Plastic pipelines are easier to install than metal pipes and are corrosion resistant,
og idet de også har glatte overflater, vil de ha mindre tendens til oppsamling av smuss og andre materialer enn tilsvarende ledninger av metall. På grunn av plastmaterialets ettergivende beskaffenhet vil sådanne rør heller ikke så lett bli påført permanente skader. and since they also have smooth surfaces, they will have less of a tendency to collect dirt and other materials than similar metal wires. Due to the flexible nature of the plastic material, such pipes will not easily suffer permanent damage either.
Innbyrdes sammenføyning av plastrør utføres vanligvis ved hjelpThe jointing of plastic pipes is usually carried out with the help of
av bindemidler eller konvensjonelle gjengeforbindelser.of binders or conventional threaded connections.
Den glatte utside av plastrør fører imidlertid dessverre tii visse vanskeligheter under installasjonsarbeidet, idet det er vanskelig å gripe og fastholde røret på en måte som er nødvendig for å However, the smooth exterior of plastic pipes unfortunately leads to certain difficulties during the installation work, as it is difficult to grip and hold the pipe in a way that is necessary to
utføre en skrueforbindelse ved anvendelse av rørtenger eller skiftnøkler. Særlig vil det nødvendige gripetrykk lett føre til deformasjon av røret, samtidig som rørmaterialets bøyelige beskaffenhet sammen med den glatte røroverflate bare fører til at røret dreier seg ved påføring av det nødvendige dreiemoment for sammenskruing. perform a screw connection using pipe pliers or spanners. In particular, the necessary gripping pressure will easily lead to deformation of the pipe, while the flexible nature of the pipe material together with the smooth pipe surface only causes the pipe to rotate when the necessary torque is applied for screwing together.
Anvendelse av hansker, mellomlegg og andre-vanlige fremgangsmåter •for å overvinne denne vanskelighet og øke friksjonen mellom et skruegrep og røret kan være til hjelp, men kan vanskelig helt løse det ovenfor angitte problem. The use of gloves, spacers and other common methods to overcome this difficulty and increase the friction between a screw handle and the pipe can be helpful, but can hardly completely solve the above-mentioned problem.
I henhold til foreliggende oppfinnelse er det imidlertid fremskaffet et ledningsrør av plastmaterial og utstyrt med en eller flere langsgående ribber på rørets ytterside, med det formål å øke rørets ytterflate og lette fast grep om røret. According to the present invention, however, a conduit pipe made of plastic material has been provided and equipped with one or more longitudinal ribs on the outside of the pipe, with the aim of increasing the pipe's outer surface and facilitating a firm grip on the pipe.
Hver sådan langsgående ribbe kan være fremstilt adskilt fra røret og forenet med dette etter rørets tilvirkning. Ribbene kan være utført.i et plastmaterial forskjellig fra plastmaterialet i røret forøvrig, og hver ribbe kan i seg selv være forsynt med et antall langsgående utstikkende partier på overflaten. Each such longitudinal rib can be produced separately from the tube and united with it after the tube is manufactured. The ribs can be made of a plastic material different from the plastic material in the pipe in general, and each rib can itself be provided with a number of longitudinally protruding parts on the surface.
Røret kan være utført i kryssbundet polyolefin-material, eller alternativt bestå av polyvinylklorid, polybutylen, polypropylen eller polyetylen. The pipe can be made of cross-linked polyolefin material, or alternatively consist of polyvinyl chloride, polybutylene, polypropylene or polyethylene.
Vedkommende ribbe kan også være utført i et termoplastmaterial av typen polyetylen eller polypropylen. The ribs in question can also be made of a thermoplastic material of the type polyethylene or polypropylene.
Ribbene kan være farvet ved hjelp av forskjellige pigmenter eller farvestoff for å gi muligheter for å fastslå rørets art og/eller tverrsnittsdimensjon eller egenskaper. The ribs may be colored using various pigments or dyes to provide opportunities to determine the nature and/or cross-sectional dimension or characteristics of the pipe.
I henhold til foreliggende^oppfinnelse kan to eller tre langsgående ribber være anordnet på overflaten av et rør, og det er funnet at anordning av sådanne striper gir muligheter for å oppnå forbedret grep om røret med tenger o.l. According to the present invention, two or three longitudinal ribs can be arranged on the surface of a pipe, and it has been found that the arrangement of such strips provides opportunities to obtain an improved grip on the pipe with pliers and the like.
Foreliggende oppfinnelse omfatter også en fremgangsmåte for fremstilling av ekstruderte rør med en eller flere langsgående ribber på overflaten, idet fremgangsmåtens særtrekk i henhold til oppfinnelsen består i at en betraktelig sammenhengende lengde av en termoplastribbe^bringes i kontakt med rørets ytterflate etter ekstruderingen ved en temperatur hvorved røret og/eller ribben befinner seg over mykningspunktet, hvoretter ribben og røret presses sammen og derpå avkjøles for å oppnå sammenføyning mellom rør og ribbe. The present invention also includes a method for the production of extruded tubes with one or more longitudinal ribs on the surface, the special feature of the method according to the invention being that a considerable continuous length of a thermoplastic rib is brought into contact with the outer surface of the tube after extrusion at a temperature whereby the pipe and/or the rib is above the softening point, after which the rib and the pipe are pressed together and then cooled to achieve joining between the pipe and the rib.
Ved en spesiell utførelse av foreliggende oppfinnelse kan ribben befinne seg ved romtemperatur mens rørets temperatur kan være av størrelsesorden 200°C. Kontakt av ribben med røret vil føre til en viss nedsmeltning av ribben for frembringelse av sammenføyning mellom ribbe og rør. In a particular embodiment of the present invention, the rib can be at room temperature, while the temperature of the tube can be of the order of 200°C. Contact of the rib with the pipe will lead to a certain melting of the rib to produce a joint between the rib and the pipe.
I det følgende vil et utførelseseksempel av oppfinnelsens rørledning bli beskrevet under henvisninq til de vedføyde teqninqer, hvorpå: Fiq. 1 er en perspektivskisse av en rørledning i henhold til foreliqqende oppfinnelse, oa In the following, an embodiment of the pipeline of the invention will be described with reference to the attached techniques, whereupon: Fig. 1 is a perspective sketch of a pipeline according to the present invention, among others
Fi<q>. 2 viser skjematisk apparatur for fremstilling av rør iFi<q>. 2 shows schematic apparatus for the production of pipes i
henhold til oppfinnelsens fremqanqsmåte.according to the method of the invention.
I fiq. 1 er et rør 10 av kryssbundet polyetvlenmaterial på sin ytterflate 11 forsynt med tre lanqsqående ribber 12, som hver er utført i polyetylen av termoplasttype oq sammensmeltet med det kryssbundne<p>ol<y>etvlenmaterial i røret 10. Hver ribbe har forskielliq farve for å anqi rørets art oq eqenskaper. Videre har hver ribbe en hovedsakeliq halv-sylinderformet ytterflate 13. In fig. 1, a tube 10 of cross-linked polyethylene material is provided on its outer surface 11 with three longitudinal ribs 12, each of which is made of polyethylene of the thermoplastic type and fused with the cross-linked polyethylene material in the tube 10. Each rib has a different color for to anqi the pipe's nature oq equations. Furthermore, each rib has a main half-cylindrical outer surface 13.
Det kryssbundne polyetylen-rør 10 er vanligvis fremstilt ved. ekstrudering. Når røret 21 forlater ekstruderinqsapparatet 20, The cross-linked polyethylene pipe 10 is usually made of wood. extrusion. When the pipe 21 leaves the extrusion apparatus 20,
har det en temperatur av størrelsesorden 200°C og føres over et bord 22, idet et platestempel 23 er anordnet over bordplaten. En rull 24 av ribbematerial 25 av termoplast-polyetylen fremføres mot rørets overflate oq føres under platestemplet 23 for pressinq av strimlen mot røroverflaten. Virkningen av at strimlen 25 trykkes til anlegg mot den varme yttervegg av røret 21, er at den del av ribben som befinner seg i kontakt med røret, mykner således at det frembringes sammensmeltning mellom rør og ribbe. Etter å it has a temperature of the order of 200°C and is passed over a table 22, a plate stamp 23 being arranged above the table top. A roll 24 of ribbed material 25 of thermoplastic polyethylene is advanced towards the surface of the pipe and is passed under the plate punch 23 for pressing the strip against the pipe surface. The effect of the strip 25 being pressed into contact with the hot outer wall of the pipe 21 is that the part of the rib which is in contact with the pipe softens so that a fusion between the pipe and the rib is produced. After
ha passert bordet 22 og platestemplet 23, føres røret med påførte ribber på ytterflaten gjennom et kjølebad 26 for avkjøling av rørveggen, hvoretter den fremstilte rørledning med langsgående ribber på sin ytterflate overføres fra kjølebadet for oppvikling på en spole eller trommel. having passed the table 22 and the plate punch 23, the pipe with applied ribs on the outer surface is passed through a cooling bath 26 to cool the pipe wall, after which the manufactured pipeline with longitudinal ribs on its outer surface is transferred from the cooling bath to be wound on a coil or drum.
Det er funnet at rørledninger med en eller flere ribber på yttersiden og fremstilt på den måte som er angitt ovenfor, oppviser den egenskap at rørledningen lett kan gripes av et verktøy eller med hendene, samt at rørets tendens til å dreie seg i grepet under påføring av dreiemoment i vesentlig grad er nedsatt. It has been found that pipelines having one or more ribs on the outside and made in the manner indicated above exhibit the property that the pipeline can be easily gripped by a tool or by hand, and that the tendency of the pipe to rotate in the grip during the application of torque is significantly reduced.
