<\/h1>\n

De meeste industrie\u00ebn zijn tegenwoordig afhankelijk van zware machines en robuuste apparatuur om zware lasten te tillen, grote hoeveelheden materiaal te verplaatsen en meer. Al deze gereedschappen zijn afhankelijk van drukleidingen voor hydrauliek, brandstoftoevoer en meer. Gespecialiseerd draden <\/a>worden vaak gebruikt om betrouwbare, afgedichte verbindingen te vormen voor hydraulische vloeistof of vloeibare brandstoffen, zodat deze effectief en zonder storingen honderden of duizenden uren lang onder hoge druk kunnen stromen.\u00a0<\/span><\/p>\n

Deze speciale schroefdraden zijn verkrijgbaar in vele verschillende specificaties, zoals NPT, BSPT, JIS en meer. Het begrijpen van de verschillen tussen de specificaties is essentieel om goede afdichtingen en een betrouwbare werking van de apparatuur te garanderen. Verschillende schroefdraden kunnen niet op elkaar worden afgestemd, anders treedt er een afdichtingsfout op. Daarom moeten professionals de verschillen kunnen herkennen voordat ze gevaarlijke fouten maken bij het repareren of upgraden van drukleidingen of andere schroefdraadfittingen.\u00a0\u00a0<\/span><\/p>\n

De belangrijkste draadtypen identificeren<\/span><\/h2>\n

Er zijn veel verschillende parallelle en taps toelopende draadpatronen om rekening mee te houden. Zodra u begrijpt dat parallelle draden een recht profiel behouden, terwijl taps toelopende draden van breder naar smaller lopen, kunt u de verschillende profielen identificeren waarmee u diverse specificaties kunt identificeren, zoals NPT, BSP, JIS, SAE of metrisch.\u00a0<\/span><\/p>\n\n\n\n

    NPT of NPTF staat voor National Pipe Thread, en deze schroefdraden hebben een taps toelopend ontwerp. Zowel NPT- als NPTF-schroefdraden lopen taps toe, maar voor een betrouwbare afdichting is het nodig om een afdichtingsmiddel, zoals teflontape, toe te voegen. NPTF-schroefdraden zijn gemaakt om een strakkere mechanische afdichting te vormen en bieden een effectieve droge afdichting die de voorkeur geniet bij toepassingen met hogere druk en in hydraulische systemen waar NPT-afdichtingsmiddelen de leidingen na verloop van tijd kunnen verontreinigen. NPT-fittingen hebben doorgaans een "NPT"-markering ter identificatie, maar niet alle NPT-fittingen hebben deze indicator.\u00a0<\/span><\/p>\n

      De BSP-waarde in de schroefdraadstandaard staat voor British Standard Pipe en is een standaard die veel wordt gebruikt in Europa, het Verenigd Koninkrijk en Australi\u00eb. Deze standaard heeft een schroefdraadhoek van 55 graden en wordt aangeboden met zowel taps toelopende als parallelle schroefdraadpatronen. Hoewel deze standaard sterk lijkt op NPT, is hij niet compatibel. Wanneer BSP- en NPT-fittingen worden gecombineerd, kunnen er lekken ontstaan. BSP-fittingen worden doorgaans gemarkeerd met "G", "R" of "Rp" voor identificatiedoeleinden.\u00a0<\/span><\/p>\n

        JIS is een bekende schroefdraadstandaard die veel gebruikt wordt in Azi\u00eb. JIS staat voor Japanese Industrial Standards (Japanse industri\u00eble standaarden) en dit gestandaardiseerde schroefdraadontwerp lijkt sterk op het BSP-schroefdraadontwerp. JIS-fittingen zijn verkrijgbaar in zowel parallelle als taps toelopende uitvoeringen en kunnen vaak samen met BSP-fittingen worden gebruikt, maar voor een effectieve afdichting is een extra afdichtingsmiddel nodig.\u00a0<\/span><\/p>\n

        Soms zijn JIS-fittingen voorzien van een "JIS"-markering, waardoor de standaard eenvoudig te identificeren is. Zonder deze markeringen moeten gebruikers letten op de 30-graden flare aan het uiteinde van een JIS-verbinding of een 37-graden flare voor een JIC-verbinding.\u00a0<\/span><\/p>\n

        SAE-schroefdraad wordt gereguleerd door de Society of Automotive Engineers. Deze schroefdraden zijn meestal recht en maken gebruik van o-ringen voor een effectieve vloeistofafdichting. SAE-schroefdraad en -fittingen worden vaak gebruikt voor mechanische fittingen en zijn minder afhankelijk van vloeistof- of gasdichte fittingen dan NPT-fittingen. Iedereen die een SAE-schroefdraad identificeert, moet een SAE-spoedmeter gebruiken om de maat te bepalen. SAE-fittingen hebben doorgaans SAE-markeringen en een inch-markering.\u00a0<\/span><\/p>\n

        Metrisch draadtype<\/span><\/h3>\n

        Metrische schroefdraad is gestandaardiseerd door de ISO, oftewel de International Organization for Standardization. Een bout of andere fitting met metrische schroefdraad wordt doorgaans herkend aan de aanwezigheid van de letter "M" en een diameterwaarde. Metrische schroefdraad wordt meestal gebruikt in bevestigingsmiddelen of mechanische fittingen en is doorgaans gebaseerd op parallelle draden<\/strong>, hoewel er ook enkele taps toelopende varianten bestaan.\u00a0<\/span><\/p>\n

        Metrische schroefdraad wordt veel gebruikt in Europa en vele andere gebieden wereldwijd. Een metrische schroefdraadmeter moet worden gebruikt om een specifiek schroefdraadpatroon correct te identificeren.\u00a0<\/span><\/p>\n

        Alternatieven voor schroefdraadfittingen voor hydraulische toepassingen<\/span><\/h2>\n

        Hydraulische systemen zijn sterk afhankelijk van schroefdraadfittingen omdat ze gebruiksvriendelijk, veelzijdig en betrouwbaar zijn. Schroeffittingen zijn echter niet de enige beschikbare optie. Er zijn fittingen die afhankelijk zijn van knelkoppelingen, flenskoppelingen, push-to-connect-koppelingen, ORFS-koppelingen (O-ring face seal) of snelkoppelingen.\u00a0<\/span><\/p>\n

        Knelkoppelingen<\/span><\/h3>\n

        Een knelfitting is gebaseerd op een samendrukbaar metaalmateriaal dat in een smal profiel wordt geperst dat de buis op zijn plaats houdt. Knelfittingen hebben de voorkeur in situaties waarin de te bevestigen buis niet kan worden gedraaid en solderen moeilijk of onmogelijk is. De buis wordt in de knelfitting geplaatst en met een gereedschap wordt het knelgedeelte van de fitting samengedrukt om de buis op zijn plaats te persen en een betrouwbare afdichting te vormen.\u00a0<\/span><\/p>\n

        Push-To-Connect<\/span><\/h3>\n

        Push-to-connect-fittingen worden soms gebruikt in hydraulische installaties waar eenvoud en snelheid de twee belangrijkste factoren zijn. Deze robuuste fittingen maken gebruik van een taps toelopende vrouwelijke fitting, vaak voorzien van weerhaken en een O-ringafdichting. Wanneer de buis in de fitting wordt gedrukt, klemt de speciaal gevormde vrouwelijke fitting de buis vast, zodat deze niet kan worden verwijderd zonder de vergrendeling los te maken. Push-to-connect-fittingen zijn duurder en veel experts zijn van mening dat ze minder betrouwbaar zijn dan schroefdraadfittingen, maar ze zijn wel snel en handig.\u00a0<\/span><\/p>\n

        ORFS<\/span><\/h3>\n

        Een ORFS- of O-ring face seal fitting is afhankelijk van een O-ring in de lip van een verbinding en een schroefdraadfitting voor een duurzame afdichting. Deze fittingen zijn vaak iets duurder dan schroefdraadfittingen, maar bieden in veel situaties een superieure bescherming op lange termijn.\u00a0<\/span><\/p>\n

        Snelkoppelingen<\/span><\/h3>\n

        Snelkoppelingen zijn eenvoudig aan te sluiten en los te koppelen en zorgen voor een afdichting door de uitlopende mannelijke en vrouwelijke delen samen te drukken met rubber of een ander samendrukbaar materiaal aan elke kant. De koppeling drukt het rubber samen tot een betrouwbare afdichting die snel kan worden hersteld door de fitting los te koppelen. Ze zijn ideaal voor situaties waarin frequent aan- en afkoppelen vereist is, maar zijn minder betrouwbaar voor langdurige afdichtingen dan schroefdraadfittingen.\u00a0<\/span><\/p>\n

        Conclusie<\/span><\/h2>\n

        Met zoveel verschillende draadstandaarden wereldwijd is het belangrijk om de verschillen te begrijpen en te weten welke standaard op uw apparatuur wordt gebruikt. Gebruik deze handleiding om de juiste fittingen te vinden voor eventuele reparaties of upgrades, en u zult genieten van betrouwbare prestaties. <\/span><\/p>","protected":false},"excerpt":{"rendered":"

        Most industries today depend on heavy machinery and rugged equipment to lift heavy loads, move large volumes of materials, and more.
