If you\u2019re an engineer scratching your head over which convoluted tubing to pick for your next project, you\u2019re not alone. I\u2019ve been in those meetings where we debate forever about bend radius, flow restrictions, and how the thing holds up under pressure. Convoluted PTFE tubing is awesome for tough spots \u2013 chemicals, high temps, tight spaces \u2013 but the pitch design makes a big difference. Open pitch or closed pitch? Let\u2019s break it down without all the fluff.<\/p>\n\n\n\n

Convoluted tubing, basically that wavy PTFE stuff (Teflon if you wanna call it that), gives you way more flex than straight smooth bore tubes. The waves \u2013 or convolutions \u2013 let it snake around corners without kinking. But the spacing of those waves, that\u2019s the pitch, changes everything. Open pitch means wider spacing between the convolutions, while closed pitch packs \u2019em tighter.<\/p>\n\n\n\n

What Exactly is Pitch Design in Convoluted Tubing?<\/h2>\n\n\n\n

Pitch design is just how close or far apart those helical or annular waves are on the tube. Industry folks often call tighter spacing \u201cclose convolution\u201d or closed pitch, and wider \u201copen pitch.\u201d<\/p>\n\n\n\n

From what I\u2019ve seen in real setups, open pitch has fewer convolutions per inch. That makes the tube smoother inside for better flow, and it\u2019s great for self-draining \u2013 no pockets for stuff to hang out in. Closed pitch crams more waves in, so you get insane flexibility and a super tight bend radius.<\/p>\n\n\n\n

Think about it like this: open pitch is like a loosely coiled spring, easier to clean and push fluid through. Closed pitch? Tighter spring, bends like crazy but might add a bit more turbulence.<\/p>\n\n\n\n

Il tubo corrugato per carburante, realizzato in PTFE, supporta macchinari industriali con schermatura EMI e stabilit\u00e0 termica. La struttura in Teflon del tubo per carburante resiste a temperature estreme e sostanze chimiche. Il design flessibile compensa i disallineamenti, garantendo una manutenzione ridotta e una maggiore durata.<\/p>\n\n\t\t\t<\/div><\/div>\n\n\n
