Wokuvimbela ukuze amapayipi kanye ezahlukeneyo zalo. izidingo zifudumele

Pipelines amasistimu ezihlukahlukene, njengoba umthetho, abe obuphelele okukhulu. benza amasayithi abo zitholakala kokubili phezu kuthi laba abangaphansi komhlaba. Ngakho-ke kubalulekile ukuba ukuphumelela ukwahlukanisa kwezokuxhumana emathonyeni abandayo kanye nezinye zangaphandle kwaba ngempela eliphezulu. Wokuvimbela ukuze amapayipi abhekana ngayo nalesi msebenzi.

aphoyintimenti ukwahlukanisa

I sina kakhulu futhi evamile inkinga - ke zeqhwa amapayipi e izigaba esitaladini iphayiphi futhi amakamelo unheated. ukusetshenziswa ngihlakaniphe ukwahlukanisa uhlelo ekuqaleni kuka ukuqeda imiphumela.

Ezishisayo ukwahlukanisa ipayipi ivikela ukuxhumana kusuka ukugqwala ekuveleni izingxenye zensimbi kohlelo ngenxa ukufingqa unomphela. Ngenxa yalokho, i-ohlabayo tube bese uyehluleka.

Wokuvimbela ukuze amapayipi kusiza ukuvimbela nokushisa. Ukugcina izinga lokushisa amapayipi kohlelo bafudumale, umnikazi uzokwazi kakhulu ukunciphisa yezinkonzo zikamasipala.

Izimfuneko ipayipi heater

• Okuphansi conductivity ezishisayo, kungaba kakhulu ukunciphisa nokushisa.
• ukuqina okuphezulu futhi ukuphila isikhathi eside.
• A ububanzi lokushisa ububanzi. Ngokuzumayo lokushisa izinguquko musa kuthinte izakhiwo ukwahlukanisa, ikakhulukazi uma kuziwa amanzi ipayipi ashisayo ahlelwe ngaphandle.
• ukwahlukanisa Esinokwethenjelwa, okuyinto ngeke idabule heater amanzi noma condensate.
• Eliphezulu ukwahlukanisa for amapayipi lungekho ngaphansi ukucindezeleka kwemvelo.
• Fire ukuphepha. Lapho ukwahlukanisa piping izinhlelo zitholakala ezindaweni lapho kwenzeka umlilo (okugeza, umusi kanye nokunye. D.) Ingabe sebenzisa izinto incombustible kuphela.
• Ifakeka. Ngo ukwakhiwa ezimbonini noma azethembe ukufudumala is a plus eziqondile.

ezihlukahlukene heater

• Mineral uvolo noma basalt ukwahlukanisa. Lokhu kwaziswa ephezulu amandla nge kwesikhathi sokuphila kuqhathaniswa eside. Ububanzi lokushisa yokusetshenziswa ubanzi kakhulu - kusuka -60 ° C kuya +200 ° C. Ukuvumelana nezimo futhi adhesion ezinhle. Ngaphezu kwalokho luqiniswe ingilazi yoboya noma ucwecwe.
• Glass uvolo has a conductivity ongaphakeme ezishisayo - kusuka 0,028 kuya 0,034 W / m. Kuyinto impahla non-ezivuthayo futhi is hhayi obala okushisa aphakeme. Ingabe ethile eyodwa kuphela - hygroscopic kakhulu, ngakho-ke, kudinga isendlalelo nangokuvikela impahla ngaphandle. Njengoba ukwahlukanisa Ukushisa amashubhu esetshenziswa impela njalo engomunye nezinsiza ezingcono - ruble ngalinye 1 kg 60 kuya ku-80.

• Ukwahlukanisa of polystyrene foamed, eqinisweni, Foam efanayo, kodwa ngendlela ethile. Kuyinto ngempumelelo ukusebenzisa ezingeni lokushisa kusuka -80 ° C kuya + 180 ° C. conductivity wayo ezishisayo ingaphezu kwe-izinto odlule - 0.05 W / m. Naphezu kwakho konke lokhu, futhi azigcina nokushisa kahle. Izinzuzo zihlanganisa kalula ukufakwa - ekhiqizwa ngesimo ama-, okuyinto impela nje ukugoqa engxenyeni ipayipi unamathelise nengxenye. Olwelwesini ukwahlukanisa ine ikhava yangaphandle okwandisa ukuqina yayo. Izindleko incike ubukhulu kanye impahla ukujiya. Ukwahlukanisa thinnest kubiza ruble ngu-60. ngamunye imitha square.
• Wokuvimbela ukuze amapayipi "igobolondo" eyenziwe polyurethane futhi kufana e impahla yayo kuya Foam. Siqukethe halves ezimbili, kepha efaniswe ziyadliwa amagobolondo, okuyinto esikhulu tube kusukela izinhlangothi ezimbili futhi egxilile wire. Nge kwabantu ephakeme futhi cishe Coefficient efanayo conductivity ezishisayo, le nto kulula ukubekezelela imithelela mechanical ngokwanele thermally nangokuvikela okushisa kusuka -180 ° C kuya +130 ° C. Lapho ukuliqaqa azigcina zonke impahla zalo nangokuvikela, ngakho-ke lingasetshenziswa kabusha. Kuyoba izothatha iminyaka engu-30. Lokho okwakudingeka ukuze kukhokhwe ukwahlukanisa elisukela ruble 200 1000, kuye ngobukhulu besikhumba saleso impahla.

• ukwahlukanisa Akubizi futhi kulula - polyethylene Foam. Ngenxa isakhiwo esihle-anezikhala azigcina nokushisa kahle. conductivity wayo ezishisayo akazidluli 0.05 W / m. Operating lokushisa lebanga ukusuka -50 ° C kuya +90 ° C. It has a isisindo ongaphakeme ukushuba, futhi ngaleyo ndlela wonge ndawo. Luhlala Isikhathi Eside, yena izothatha iminyaka engaphezu kuka-100. Intengo incike ukujiya ishidi futhi cishe ruble 160-200 imitha ngalinye.

• Omunye lamadolobha esimanjemanje kakhulu ukwahlukanisa izinto kuyinto ukwahlukanisa liquid amapayipi. It has aphansi conductivity ezishisayo - 0.01 W / m, buhlanjululwe ngamanzi bese sisetshenziswa kalula. Ngesimo ezomile livikela kusuka umswakama, ngempumelelo silondoloza ukushisa. Intengo ruble 350-400 ilitha.

obandayo

He is engaphansi ngokuphelele kulokho kuthatha ukwahlukanisa. Ukuze amapayipi kodwa angabangi umsindo evame ukusetshenziswa ingilazi uboya bezimvu inqubo isicelo yayo silula. Plast is nilimaza phezu tube futhi fixed ngethephu enamathelayo emhlabeni azungezwe. Lokhu kuqinisekisa ubuqotho isakhiwo ngisho noma ipayipi is zikhubazekile ngu phansi ukufuduka.

intengo udaba

Ububanzi intengo for ukwahlukanisa for amapayipi enkulu ngokwanele, konke kuncike uhlobo impahla kanye nomkhiqizi. Eshibhe - polyethylene Foam. izindleko ezibizayo zonke igobolondo polyurethane futhi ukwahlukanisa ketshezi. Ukuthembeka kanye nokusebenza esiphelele Izinsiza eziningi zinquma khona ntofontofo. Kuyinto njalo kungenzeka ukuba ukhethe ipayipi heater, intengo elitholakala, futhi izici lobuchwepheshe isiqinisekiso ukuhlinzwa ukonga futhi ngokucophelela kwamanzi nokuthuthwa bafudumale izinhlelo.
