Izindaba - Iyini ipayipi eligoqekile le-PTFE

Incazelo yomkhiqizo:

Ipayipi eligoqekile le-PTFE(ebizwa nangokuthi i-PTFE corrugated hose), igama eligcwele yi-polytetrafluoroethylene hose, yakhiwe nge-convoluted PTFE tube liner kanye ne-strainless steel outer braid eyodwa noma ezimbili. Ngenxa yezici zesimo sayo sejometri, i-hose ingabona ushintsho lobude be-axial be-Convoluted hose ngaphansi kwesenzo sokucindezela, amandla e-axial, amandla aseceleni kanye nomzuzu wokugoba. Ubude be-Convoluted hose bunwetshwa ngaphansi kwesenzo samandla okudonsa; ubude be-Convoluted hose bufinyezwa ngaphansi kwesenzo samandla okucindezela. Ubude noma inani eligobekayo le-Convoluted hose linqunywa yizici ezifana nenani kanye nesiqondiso samandla, kanye nemingcele yokusebenza ye-Convoluted hose. Umehluko phakathi kwayo ne-smooth tube ukuthi ngaphezu kwamandla athile nokuqina, iphinde ibe nokuguquguquka okukhulu kanye nokumelana nokukhathala okuphezulu. Lezi zakhiwo zenza i-hose ibe nohlu olubanzi kakhulu lwezicelo

Ubuciko:

Amapayipi ahlanganisiwe e-PTFE enziwa ngobuchwepheshe bokufutha. Sifaka ipayipi esikhumbeni sokushisa. Uma lishiswa lifike ezingeni lokushisa elithile, kunikezwa ingcindezi ethile yangaphakathi epayipini ukuze kwandiswe ipayipi eceleni (inflate), bese lenziwa ngokupholisa nokubumba. Ngakho-ke ipayipi elihlanganisiwe liyaqedwa

Izici Zomkhiqizo:

Isici esiyinhloko sepayipi elihlanganisiwe le-PTFE ukuthi linokuguquguquka okukhulu nokugobeka, futhi irediyasi yalo encane yokugoba iyanda ngokwanda kobubanzi bepayipi. Leli payipi elihlanganisiwe linezakhiwo ezingokwemvelo ze-PTFE, futhi linokuguquguquka okuphezulu nokunwebeka. Ngokusho kwesimo esihlanganisiwe, kunezinhlobo ezintathu: uhlobo lwe-V, uhlobo lwe-U kanye nohlobo lwe-Ω. Njengesixhumi sepayipi elimelana nokugqwala, lidlala indima ekumunceni ushintsho kubude bepayipi okubangelwa ukwanda kokushisa nokugoba, futhi linendima yokuxhumeka okuhlanganisiwe kwepayipi eliqinile nelithambile. Ukuze kuthuthukiswe ukusebenza, ipayipi elihlanganisiwe lingaqiniswa futhi ngamasongo ensimbi, imikhono yensimbi, irabha, njll. Ipayipi langaphakathi elihlanganisiwe lenziwe nge-resin ye-PTFE engu-100%, ejikeleziswa ibe yipayipi elihlanganisiwe elijikelezayo, elisetshenziswa njengepayipi lokuvikela ucingo kanye nokuthutha imithombo yoketshezi ebolayo. Njengamanje, iningi lepayipi elihlanganisiwe emakethe lenziwe ngezinto ze-PE noma ze-PVC, ezingamelani kakhulu nokushisa nokugqwala kune-PTFE. Ngaphezu kwalokho, ipayipi eligoqekile le-PTFE linokumelana okuhle kakhulu nokugqwala, ukuguquguquka okuphezulu kanye nokuqina, izakhiwo ezinhle kakhulu ze-dielectric, kanye nokumelana nokuguga kanye nokuphila isikhathi eside kwenkonzo.

Izakhiwo zamakhemikhali:

1. Ukumelana nokuguga komoya, ukumelana nemisebe kanye nokuvuleka okuphansi: ukuchayeka isikhathi eside emoyeni, ebusweni kanye nokusebenza akushintshi.

2. Ukungashi: Inkomba yomkhawulo we-oxygen ingaphansi kwama-90.

3. Ukumelana ne-asidi ne-alkali: okunganyibiliki kuma-asidi aqinile, ama-alkali aqinile kanye nezinyibilikisi eziphilayo.

4. Ukumelana ne-oxidation: ukumelana nokugqwala yi-oxidants enamandla

Indlela yokuxhuma:

Kunezindlela eziningi zokuxhuma ipayipi eligoqekile. Ngokuvamile, ukuxhumana kwe-flange, ukuxhumana okungenawoyela, ukuxhumana okunezintambo, ukuxhuma okusheshayo, kanye nokuxhumana okuqondile nge-hose fittings kungasetshenziswa, futhi kulungiswe nge-hose clamp noma ucingo lwensimbi. Ifektri yethu inganikeza nezindlela zokuxhuma ezihambisanayo ngokwezidingo zomsebenzisi.

Amapayipi e-corrugated ane-DN10-150mm nobude obungu-20-20000mm anganikezwa, izinga lokujiya kodonga lingu-1.5mm-2.2m, futhi inani lemijikelezo yokukhathala liyi≥100,000. Imininingwane ethile kanye nemingcele yobuchwepheshe yeipayipi elihlanganisiwe elinikeziwe lingenziwa ngokwezidingo zamakhasimende

Izici zamakhemikhali:

1. Inokumelana nokushisa okuphezulu kanye nokumelana nokushisa okuphansi. Ukushisa kwayo okuphezulu kungafinyelela ku-250℃, futhi izinga lokushisa layo eliphansi lingancishiswa libe yi--65℃.

2. Inezici zokumelana nokugqwala futhi ingamelana nokusebenza kwawo wonke ama-asidi aqinile (kufaka phakathi i-aqua regia), ama-oxidant aqinile, ama-reducing agents kanye nezinyibilikisi ezahlukahlukene zezinto eziphilayo ngaphandle kwezinsimbi ze-alkali ezincibilikisiwe, imidiya ye-fluorinated kanye ne-sodium hydroxide engaphezu kwama-300°C. Ingasetshenziswa emipayipini enamandla ye-asidi ne-alkali.

3. Inomphumela wokulwa nokuguga, ukumelana nokuguga emoyeni, ukumelana nemisebe kanye nokungangeni kahle kwamanzi. Ukuchayeka isikhathi eside emoyeni, ubuso kanye nokusebenza akushintshi, impilo yesevisi.

4. Ayinabo ubuthi futhi iphephile, futhi ingasetshenziswa ekuthuthweni koketshezi oluhlukahlukene.

5. Ukungashi: Inkomba yomkhawulo womoya-mpilo ingaphansi kwama-90.

6. Inokuguquguquka okuphezulu kanye nokunwebeka.

7. Izimbobo ze-PTFE zingasetshenziswa futhi endandatho yensimbi, umkhono wensimbi, irabha nokunye ukuqinisa.

8. Ingasetshenziswa ukuxhuma uxhumano oluhlanganisiwe lwamapayipi aqinile futhi abuthakathaka

ukusetshenziswa:

1. Ingasetshenziswa njenge-reactor kanye ne-exchanger yeshubhu ngezikhathi ezikhethekile;

2. Ingasetshenziswa njengepayipi lokudla nokukhipha iloli yethangi, ithangi lokugcina, isitsha kanye nekettle yokusabela;

3. Ingasetshenziswa ukufaka esikhundleni se-graphite, i-ceramic, ingilazi kanye namanye amapayipi ngamandla aphansi okusebenza;

4. Ingasetshenziswa ekuxhumeni ipayipi ngokungalungi noma isetshenziswe ukulinganisela ukufuduka kwepayipi kanye nezinguquko zobukhulu ezibangelwa isimo sezulu noma ezinye izizathu noma ukuqeda ukudlidliza komshini okuvama kakhulu
