Zifudumele ngoba ipayipi Ukushisa bengaphandle flat: nezinhlamvu, Ubukhulu

Noma yimuphi iphayiphi engaphandle izakhiwo, zidinga ukwahlukanisa. Wenza okuhlukile imigqa, okuyinto ahanjiswa ngezansi ukujula okokuqandisa. Ngaphezu kwalokho, udinga ukwahlukanisa for amapayipi elise amakamelo unheated. Kwembulunga kungandisa ukusebenza emigqeni zokuxhumana futhi wandise yempilo yabo. Ukusebenzisa izinga ukwahlukanisa for amapayipi thembeke Uyakwati kubavikela umnkantsha, ukunciphisa nokushisa futhi bafudumale izinhlelo ukuqeda ukufingqa.

Edinga ukwahlukanisa of amapayipi?

wenza kahle ukushisa ukwahlukanisa ikuvumela:

• Nciphisa e Ukushisa amashubhu kanye unscheduled extra nokushisa.
• Nciphisa ipayipi komhlaba futhi ngaphakathi kungenzeka yisivikelo of condensate kumiswa.
• Nikeza elithile lokushisa phezu yisivikelo.
• Khulisa isikhathi nokusebenza ngenxa nokugqwala deceleration ipayipi.
• Vikela polypropylene kanye PVC pipe kanye ekulimaleni lokukhanda.
• zifudumele for amapayipi kodwa angabangi umsindo endaweni evulekile futhi azigcina ukushisa ebusika ukuze zingasivimbi ukuba umnkantsha.

Kanjani ukukhetha impahla kwesokudla?

Ngokuvamile, ukukhetha kusekelwe indlela yokunquma elandelayo:

• ubukhulu ipayipi;
• intengo zifudumele;
• izimo operation kuzokwenzeka ngaphansi kwayo;
• ubude iphayiphi;
• izidingo ukusebenza.

Yini ukwahlukanisa isetshenziselwa amapayipi?

Kukhethwa impahla for ukwahlukanisa kuncike ngokuvamile emgqeni okuhloswe, ipayipi ubukhulu kanye namasistimu okusebenza izimo. Indaba for the ukwahlukanisa kufanele abe naloku:

• ukushisa eliphezulu zokusindisa;
• ongaphakeme conductivity ezishisayo;
• Ukumelana umlilo;
• ukumelana namathonya amabi zangaphandle;
• lula ukufakwa - kulabo abafisa ukuchitha ukwahlukanisa kwabo siqu, lokhu kuyinto isici esibalulekile;
• angangenwa manzi;
• ngokuqina.

Ukuze Ukushisa efanele endlini anidingi kuphela ukuthenga amapayipi nezinye izakhi, kodwa futhi ukuba sinakekele yokuqinisekisa ukusebenza kwabo. Ngakho, ukuze zokuxhumana incibilikiswa ngaphansi kwethonya okushisa aphansi, kubalulekile ukuba ukuthenga izinga oyi-heater for amapayipi kodwa angabangi umsindo. Namuhla, ezihlukahlukene zokwakha zifudumele we omkhulu, kodwa ngaphambi kokuba unqume kukhethwa sokugcina kumele ayejwayele izinga yabo izici.

Ngo zifudumele kakhulu amapayipi wenza lezi zinhlobo zezindwangu:

• Polyethylene Foam (polyethylene Foam).
• Foam zenjoloba.
• Polyurethane foam.
• Mineral uvolo.

Iyatholakala njengoba zihlale zifudumele ngesimo amasilinda-basalt.

Polyethylene Foam (polyethylene Foam)

Okwamanje uma idivayisi Ukushisa ukuze zihlale zifudumele amapayipi Foam uthola isicelo impela. Kusukela izinga isilinganiso / intengo - lokhu kuyisinqumo esingcono kakhulu. Izinto zokuvala umoya eyenziwe polyethylene kephunkephu khiqiza! E 2 izinhlobo eziyinhloko:

• amashubhu imitha ezimbili;
• indwangu.

Indaba ungase ube enamathela of polyethylene, aluminium ucwecwe nokunye.

Polyethylene Foam ipayipi ukwahlukanisa sinezici ezifana:

- Coefficient ka conductivity ezishisayo (at 40 ° C.) - 0,043 W / m * K.

- okusheshayo ukumelana Coefficient pair -> 3000.

- Temperature (ukusebenza): kusuka -80 kuya +95 deg.

- flammability iqembu - izinto nonflammable (G1 futhi G2).

- Ububanzi kwesicelo - Ukushisa, ukupholisa indle izinhlelo.

- Supply - ngamapayipi.

Lokhu ukwahlukanisa for ipayipi osayizi zimi kanje: ukushuba odongeni ivela 6 kuya ku-30 mm ububanzi - 6-160 mm.

Ububanzi intengo likhulu kakhulu. Izindleko ipayipi ukwahlukanisa Chinese ezenziwe zonke 5-7 esingaphansi European, kodwa izinga lungaphezu bakhiphe elezinga eliphansi.

Okunjalo Foam ukwahlukanisa ipayipi kuyahluka obandayo kalula. Udinga nje ukusika bandwidth kudingekile, bopha futhi uvikelekile nge tape.

iraba foamed

Ngo ukusebenza ukwahlukanisa for amapayipi eyenziwe zokwenziwa Foam zenjoloba lungaphezu esiphakeme kunazo zonke ezinye izinhlobo. Kodwa izindleko ngaphezulu. Ngenxa yokuthi loluhlobo ipayipi ukwahlukanisa ngokuvamile isetshenziselwa in the izicelo ubunjiniyela olindele kunazo ezidinga ukumelana lokushisa aphansi kakhulu noma okusezingeni eliphezulu, emisebeni yelanga, umlilo futhi t. D.

The main izici zokusebenza nendaba:

- Isikhungo esibhekele ukushisa nokufudumala conductivity Coefficient 40 degrees. kuyinto 0,038 W / m * K.

- Temperature (ukusebenza): kusuka -80 kuya +95 deg.

- flammability Iqembu impahla - G1.

- Ububanzi - air-conditioning kanye ifriji izinhlelo.

- Supply - ngamapayipi of ubukhulu 6-160 mm, udonga ukushuba amanani impahla ukuze 6-32 mm.

- Indaba linamandla UV imisebe.

Liquid (futhi wafutha upende) insulators

Lena izinto empeleni esasisesisha embonini yezokwakha. Kunezinhlobo ezimbili eziyinhloko of insulators uketshezi:

1. Ukuhwamuka. Uma uyikha phezulu le kusetshenziswe ngumuntu indlela sputtering, usebenzisa amadivaysi ekhethekile (isib - PUF).
2. Painting. Basuke isetshenziswa ebusweni njengoba inki evamileusebenzisa roller noma shayela.

Bobabili ongakhetha sethubeni abalulekile: Isolators ingasetshenziswa lapho ukusetshenziswa roll izinhlobo heater noma okunzima.

polyurethane foam

Polyurethane foam isigamu-amagobolondo (amagobolondo PPU) - a ukwahlukanisa eqinile eyenzelwe zifudumele amapayipi. Mhlawumbe esehlanganise izinhlobo ezahlukene ungangenisi amanzi -. Kuyinto asphalt, ucwecwe, ucwecwe FPGK glassine, ifilimu plastic, njll Omunye izinzuzo main of lolu hlobo ukwahlukanisa kulula ukufaka. Ngokuhamba kwesikhathi iqembu labantu 2 uzokwazi ukumboza 300 m. N. Nokuningi.

izici Material:

- sostavlyaet- Thermal conductivity 0,035 W / m * K.

- Temperature (ukusebenza): -150 kuya +120 degrees.

- flammability Iqembu impahla - T3.

- Ububanzi Foam polyurethane - Ukushisa namanzi ashisayo supply.

- amasilinda Delivery nengxenye.

- Usayizi 32-1020 mm ububanzi kuyinto: odongeni ukujiya - 40 mm (noma isiko), ubude - 1-1.5 m.

Penoizol

Lokhu kwaziswa kuyahluka sezingeni eliphezulu izici ezishisayo. Isetshenziselwa ngokuvamile ngezinga ezimbonini, kusukela isicelo yayo ipayipi spray idinga ukufakwa ekhethekile.

Penoizol - amaningi ingxenye ewuketshezi ingxube, okubangela indlela sputtering. Lapho osemanzi impahla, yakha imvilophi esivaliwe emhlabeni tube, okuyinto ukushisa neze sihamba.

Kuthiwa izinto ezinjalo akakwazi ngokuthi ezishibhile.

Mineral uboya ingilazi fibre

Kuyinto yeningi kakhulu intengo indaba kukhiqizwa zisongwe namatshe.

Kungcono ukusebenzisa lolo hlobo ukwahlukanisa iphuma. Indaba ine ukufakwa elula (ipayipi kufanele bopha izingqimba eziningana futhi babe nobuhlobo obuseduze le esibophezelayo wire isakhiwo), kanye nokwenzeka isicelo amapayipi ka diameters ezahlukene.

zifudumele for amapayipi endaweni evulekile nge it is eyalo emazombezombe kanye okunamathiselwe okwalandela zokwenziwa Twine noma ngocingo engagqwali.

Kubalulekile ukukhumbula ukuthi lolu hlobo impahla kumele yentiwe kanye ungqimba ungangenisi amanzi. Outdoor ke ngiwusindise ekutholeni elina kokulahlekelwa izakhiwo njengoba endlini ukuqeda khona emoyeni impahla microparticles.

ukusebenza Thermal kwale nto muhle kakhulu.

zifudumele Ukushisa amashubhu e efulethini

Nakanjani ukuthi ikhava yebhethri egumbini akudingekile. Land Ukushisa izinhlelo zitholakala ezindaweni lapho izinga lokushisa inakekelwa induduzo, asidingi ukwahlukanisa.

Sebenzisa i-heater kufanele nokushisa at kulezo zingxenye okuyinto ahanjiswa ezakhiweni lapho izinga lokushisa Igumbi singagciniwe (isib egumbini).

zifudumele for amapayipi kodwa angabangi umsindo endaweni evulekile kanye efulethini okwethulwa emakethe zokwakha kokubili abakhiqizi ezifuywayo nayiwo European futhi Russian.

Khetha kuka vimbela amapayipi kodwa angabangi umsindo, akukho. Okokuqala, cabanga ngelithi ukusebenza ezishisayo, kuba ke obandayo lula.

Kuphela Ithuba lokugcina, banake izindleko ukwahlukanisa, ngoba ngaleyo ndlela sizokwazi ukuhlola ukusebenza kwe-ruble ngamunye atshalwe ukwahlukanisa. Eshibhile kodwa abampofu impahla izinga angafaneli futhi kancane ukusebenza, futhi esikhundleni imali elindelekile kuzoletha ukudumazeka izinkinga ezihlobene.
