A maioria das ind\u00fastrias atuais depende de m\u00e1quinas pesadas e equipamentos robustos para levantar cargas pesadas, movimentar grandes volumes de materiais e muito mais. Todas essas ferramentas dependem de linhas pressurizadas para sistemas hidr\u00e1ulicos, fornecimento de combust\u00edvel e outros. t\u00f3picos <\/a>S\u00e3o frequentemente utilizadas para formar conex\u00f5es seladas confi\u00e1veis para que fluidos hidr\u00e1ulicos ou combust\u00edveis l\u00edquidos fluam em altos n\u00edveis de press\u00e3o de forma eficaz por centenas ou milhares de horas sem falhas.\u00a0<\/span><\/p>\n

Essas roscas especiais est\u00e3o dispon\u00edveis em diversas especifica\u00e7\u00f5es, como NPT, BSPT, JIS e outras, e compreender as diferen\u00e7as entre elas \u00e9 essencial para garantir veda\u00e7\u00f5es adequadas e o funcionamento confi\u00e1vel dos equipamentos. Roscas com especifica\u00e7\u00f5es diferentes n\u00e3o podem ser combinadas entre si, sob risco de falha na veda\u00e7\u00e3o. Por isso, os profissionais precisam ser capazes de identificar as diferen\u00e7as antes de cometer erros perigosos ao realizar reparos ou atualiza\u00e7\u00f5es em tubula\u00e7\u00f5es pressurizadas ou outras conex\u00f5es roscadas.\u00a0\u00a0<\/span><\/p>\n

    NPT or NPTF stands for National Pipe Thread, and these threads utilize a tapered design. Both NPT and NPTF threads are tapered, but NPT requires the addition of a sealant, such as teflon tape, for a reliable seal. NPTF threads are made to crush to a tighter mechanical seal and provide an effective dry seal that’s preferable for higher pressure uses and for hydraulic systems where NPT sealants could potentially contaminate the lines over time. NPT fittings and commonly feature an “NPT” marking for identification, but not all NPT fittings have this indicator.\u00a0<\/span><\/p>\n

      The BSP in the thread standard stands for British Standard Pipe and is a standard used heavily throughout Europe, the UK, and Australia. This standard has a 55-degree thread angle and is offered with both tapered and parallel thread patterns. Although this standard is very similar to NPT, it is not compatible, and when BSP and NPT fittings are combined, leaks will occur. BSP fittings are commonly marked with “G”, “R”, or “Rp” for identification purposes.\u00a0<\/span><\/p>\n

        JIS is a well-known thread standard that’s heavily used throughout Asia. JIS stands for Japanese Industrial Standards, and this standardized thread design is very similar to the BSP thread style. JIS fittings are available in both parallel and tapered designs and can often be used alongside BSP fittings, but an additional sealant must be included for an effective seal.\u00a0<\/span><\/p>\n

        Sometimes, JIS fittings feature a\u00a0 “JIS” marking, making it simple to identify the standard. Without the markings, users should look for the 30-degree flare at the end of a JIS connection or a 37-degree flare for a JIC connection.\u00a0<\/span><\/p>\n

        Hydraulic systems rely heavily on threaded fittings because they’re simple to use, versatile, and reliable. Threaded fittings are not the only option available, however. There are fittings that rely on compression, flange, push-to-connect, ORFS (o-ring face seal), or quick couplings.\u00a0<\/span><\/p>\n

        Conex\u00f5es de compress\u00e3o<\/span><\/h3>\n

        A compression fitting relies on a compressible metal material that’s squeezed into a narrow profile that locks the pipe into position. Compression fittings are preferred in situations where the pipe to be attached cannot be spun, and soldering is difficult or impossible. The pipe is placed inside the compression fitting and a tool is used to squeeze the compression portion of the fitting to crimp the pipe into position forming a reliable seal.\u00a0<\/span><\/p>\n

        As conex\u00f5es de encaixe r\u00e1pido s\u00e3o frequentemente utilizadas em instala\u00e7\u00f5es hidr\u00e1ulicas onde simplicidade e rapidez s\u00e3o os dois fatores mais importantes. Essas conex\u00f5es robustas dependem de uma rosca f\u00eamea c\u00f4nica, geralmente equipada com espig\u00f5es e uma veda\u00e7\u00e3o de anel O. \u00c0 medida que o tubo \u00e9 pressionado na conex\u00e3o, a rosca f\u00eamea com formato especial fixa o tubo firmemente na posi\u00e7\u00e3o, impedindo sua remo\u00e7\u00e3o sem desengatar a trava. As conex\u00f5es de encaixe r\u00e1pido s\u00e3o mais caras e muitos especialistas acreditam que sejam menos confi\u00e1veis do que as conex\u00f5es rosqueadas, mas s\u00e3o r\u00e1pidas e pr\u00e1ticas.\u00a0<\/span><\/p>\n

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

        Uma conex\u00e3o ORFS (ou com veda\u00e7\u00e3o frontal por anel de borracha) utiliza um anel de borracha integrado \u00e0 borda da conex\u00e3o e uma rosca para garantir uma veda\u00e7\u00e3o dur\u00e1vel. Essas conex\u00f5es costumam ser um pouco mais caras do que as conex\u00f5es roscadas, mas oferecem prote\u00e7\u00e3o superior a longo prazo em diversas aplica\u00e7\u00f5es.\u00a0<\/span><\/p>\n

        Engates r\u00e1pidos<\/span><\/h3>\n

        Os engates r\u00e1pidos s\u00e3o f\u00e1ceis de conectar e desconectar, proporcionando uma veda\u00e7\u00e3o atrav\u00e9s da compress\u00e3o das se\u00e7\u00f5es macho e f\u00eamea alargadas, unidas por uma borracha ou outro material compress\u00edvel em cada lado. A a\u00e7\u00e3o de acoplamento pressiona a borracha, formando uma veda\u00e7\u00e3o confi\u00e1vel que pode ser rapidamente desfeita ao desacoplar a conex\u00e3o. S\u00e3o ideais para situa\u00e7\u00f5es que exigem conex\u00e3o e desconex\u00e3o frequentes, mas s\u00e3o menos confi\u00e1veis para veda\u00e7\u00f5es de longo prazo em compara\u00e7\u00e3o com conex\u00f5es rosqueadas.\u00a0<\/span><\/p>\n
