An píopa cruach gan uaim íseal-teochtis féidir oibriú i dtimpeallacht an-fhuar de -45 ~ - 195 ℃. Is é an buntáiste iontach a bhaineann le píopa cruach gan uaim íseal-teocht ná gur féidir leis oibriú i dtimpeallacht an-íseal, nach bhfuil inchomparáide leisgnáth-phíopa cruach gan uaim. Tá neart maith agus cruas íseal-teocht ag an bpíobán cruach gan uaim íseal-teocht, agus úsáidtear go forleathan é i ndéantúsaíocht trealaimh íseal-teocht i dtionscail peitriliam, ceimiceacha, leasacháin agus tionscail eile le teocht oibre - 45 ~ - 195 ℃. Le forbairt na dtionscal ábhartha, ní hamháin go bhfuil na ceanglais maidir le hábhair teoranta do bhunriachtanais cosúil le hairíonna meicniúla agus airíonna táthú, ach freisin na ceanglais maidir le friotaíocht creimeadh H2S píopaí íseal-teocht.
Tá píopa cruach gan uaim íseal-teocht infheidhme maidir le hinnealtóireacht píblíne i dtimpeallacht íseal-teocht. Tá dhá phróiseas ann: líníocht fuar agus rollta te. Ó thaobh dearadh cruach, ba cheart rialú docht a dhéanamh ar dhéantús cruach, rollta, cóireála teasa agus próisis eile de phíobán cruach gan uaim íseal-teocht chun a chinntiú go bhfuil neart maith, toughness agus friotaíocht creimeadh ag píopa cruach gan uaim íseal-teocht. Maidir le ceanglais theicniúla píopa cruach gan uaim íseal-teocht, ba cheart go gcuirfí san áireamh go cuimsitheach eagraíocht táirgthe agus costas táirgthe an phíobáin chruach. Ní mór dearadh comhdhéanamh píopa cruach gan uaim íseal-teocht a chinntiú go bhfuil neart cuí ag an táirge, toughness ard-teocht íseal, agus próiseas cóireála teasa áisiúil Táthachtacht maith agus friotaíocht le scoilteadh hidrigine-spreagtha.

A: Go ginearálta tá sé 5-10 lá má tá na hearraí i stoc. nó tá sé 15-20 lá mura bhfuil na hearraí i stoc, tá sé de réir cainníochta.
5.C: An soláthraíonn tú samplaí?
an bhfuil sé saor in aisce nó breise? A: Sea, d'fhéadfaimis an sampla a thairiscint agus ní íocaimid costas lasta.
6.C: Cad é do théarmaí íocaíochta?
A: Íocaíocht<=1000USD, 100% roimh ré. Íocaíocht>=1000USD, 30% T/T roimh ré, iarmhéid roimh loingsiú.
