Tiwb sgwâr di-dor
Tiwb sgwâr (SHS):Mae tiwb sgwâr yn diwb dur â waliau tenau â chroes sgwâr gwag, hynny yw, tiwb dur â hyd ochrau cyfartal. Mae ei strwythur yn syml a sefydlog, ac mae ganddo gapasiti cario llwyth uchel. Fel arfer mynegir manylebau tiwbiau sgwâr o ran hyd ochr a thrwch wal.
Rhennir tiwbiau sgwâr yn wythiennau di-dor a weldio. Gwneir tiwbiau sgwâr di-dor trwy dyllu ac allwthio tiwbiau crwn di-dor. Mae tiwbiau sgwâr wedi'u weldio yn cael eu rholio o ddur stribed trwy driniaeth broses. Yn gyffredinol, mae'r dur stribed yn cael ei ddadbacio, ei fflatio, ei gyrlio, a'i weldio i ffurfio tiwb crwn. Yna caiff y tiwb crwn ei rolio i mewn i diwb sgwâr ac yna ei dorri i'r hyd gofynnol.
Dosbarthiad tiwbiau sgwâr:
Rhennir tiwbiau sgwâr yn ôl y broses gynhyrchu: tiwbiau sgwâr di-dor wedi'u rholio poeth, tiwbiau sgwâr di-dor wedi'u tynnu'n oer, tiwbiau sgwâr di-dor allwthiol, a thiwbiau sgwâr wedi'u weldio (tiwb sgwâr ERW).
Yn eu plith, mae tiwbiau sgwâr wedi'u weldio wedi'u rhannu'n:
(a) Yn ôl y broses - tiwb sgwâr weldio arc, tiwb sgwâr weldio gwrthiant (amledd uchel, amledd isel), tiwb sgwâr weldio nwy, tiwb sgwâr weldio ffwrnais
(b) Yn ôl sêm weldio - sêm syth weldio tiwb sgwâr, troellog weldio tiwb sgwâr
Rhennir tiwbiau sgwâr yn ôl triniaeth arwyneb: tiwb sgwâr galfanedig dip poeth, tiwb sgwâr galfanedig electro, tiwb sgwâr wedi'i orchuddio ag olew, tiwb sgwâr wedi'i biclo
Mae tiwbiau sgwâr yn cael eu dosbarthu yn ôl defnydd: tiwbiau sgwâr ar gyfer addurno, tiwbiau sgwâr ar gyfer offer peiriant, tiwbiau sgwâr ar gyfer diwydiant peiriannau, tiwbiau sgwâr ar gyfer diwydiant cemegol, tiwbiau sgwâr ar gyfer strwythurau dur, tiwbiau sgwâr ar gyfer adeiladu llongau, tiwbiau sgwâr ar gyfer automobiles, tiwbiau sgwâr ar gyfer trawstiau dur a cholofnau, tiwb sgwâr pwrpas arbennig.
Nodweddion tiwb sgwâr:
Cryfder uchel: Mae gan diwbiau sgwâr gryfderau tynnol, cywasgol a phlygu uchel, gallant wrthsefyll llwythi a phwysau mawr, ac maent yn addas ar gyfer cynhyrchu gwahanol rannau strwythurol.
Sefydlogrwydd da: Mae gan y tiwb sgwâr gywirdeb dimensiwn uchel, strwythur sefydlog, ac nid yw'n hawdd ei ddadffurfio, a all sicrhau bod gan y cynhyrchion wedi'u prosesu gywirdeb a sefydlogrwydd uchel.
Gwrthiant cyrydiad da: Ar ôl triniaeth arwyneb fel galfaneiddio a chwistrellu plastig, mae gan bibellau sgwâr ymwrthedd cyrydiad da a gallant addasu i wahanol amgylcheddau cymhleth.
Cost isel: Mae cost cynhyrchu tiwb sgwâr yn gymharol isel ac yn hawdd ei brosesu, gan ei wneud yn addas ar gyfer cynhyrchu a chymhwyso ar raddfa fawr.
