Iyiphi impahla yokufaka umusi engcono kumapayipi esitimu?

Ukuqala kobusika sekudlulile, futhi izinga lokushisa liye lehla kancane kancane, ikakhulukazi ezindaweni ezisenyakatho.Izinga lokushisa liphansi ebusika, futhi indlela yokugcina izinga lokushisa lingashintshi phakathi nokuthuthwa kwe-steam sekuyinkinga yawo wonke umuntu.Namuhla, uNobeth uzokhuluma nawe mayelana nokukhethwa kwezinto zokufakwa kwamapayipi esitimu.

Nakuba kunezinto eziningi zokufaka izinto ezisetshenziswayo uma kuqhathaniswa, izinto ezihlukene zinokusebenza okuhlukile ekusetshenzisweni kwayo.Izinto zokufakelwa ezisetshenziswa kumapayipi esitimu zikhethekile, kodwa yiziphi izinto zokufakelwa ezisetshenziselwa amapayipi esitimu?Ngesikhathi esifanayo Kufanele futhi wazi ukuthi yiziphi izinto zokufakelwa kwamapayipi we-steam, ukuze ukwazi ukukhetha kangcono impahla yekhwalithi ephezulu.

Yiziphi izinto zokufakelwa ezisetshenziselwa amapayipi omusi?

1. Ngokusho kwe-Article 7.9.3 ye-GB50019-2003 "Design Code for Heating, Ventilation and Air Conditioning", lapho kukhethwa izinto zokufakelwa kwemishini namapayipi, okubaluleke kakhulu kufanele kunikezwe izinto ezine-conductivity encane yokushisa, isici esikhulu sokumelana nomswakama, ukumuncwa kwamanzi aphansi, ukuminyana okuphansi, nomnotho obanzi.Izinto ezisebenza kahle kakhulu;izinto zokufakelwa kufanele zibe izinto ezingashi noma ezingashi;ukujiya kongqimba lwe-insulation yamapayipi kufanele kubalwe futhi kunqunywe ngokuvumelana nobukhulu bezomnotho ku-GB8175 "Iziqondiso Zokuklanywa Kwezisetshenziswa kanye Nokufakwa Kwamapayipi" ngesikhathi sokushisa.

2. Izinto zokufakelwa ezisetshenziswa kakhulu zihlanganisa ukhokho, i-aluminium silicate, i-polystyrene ne-polyurethane.Iyiphi okufanele isetshenziswe kufanele icatshangelwe ngokusekelwe ebunzimeni bepayipi lesistimu kanye nenani lempahla yokufaka.Ngokuvamile, izinto zokufakelwa ezisetshenziswa ohlelweni kufanele zifane.

3. Kulezi zinsuku, ukufakwa kwe-thermal okuvamile kusebenzisa izinto eziqinile zokufaka ukushisa okushisayo ezifana nokhokho noma i-polystyrene ecutshungulwe kusengaphambili.Ngenxa yokuthi ukusetshenziswa kwezinto ezisetshenziselwa ukushisa okushisayo kulungele ukwakhiwa futhi umphumela wokushisa oshisayo ungcono kunalowo ocutshungulwa esizeni, ngakho-ke usetshenziswa kabanzi.Kodwa-ke, kulolu hlobo lwesendlalelo se-insulation esihlanganisiwe, uma ungqimba lwe-vapor barrier lungaphathwa kahle, umhwamuko wamanzi osemoyeni uzogeleza uye kungqimba lokufaka ungqimba olusuka ezikhaleni, ngaleyo ndlela ucekele phansi ukusebenza kongqimba lwe-insulation.

Yiziphi izinto zokufakelwa kwamapayipi esitimu?

1. Ipayipi loboya bedwala,
Amapayipi oboya bedwala asetshenziswa kakhulu ekushiseni okushisayo kwama-boilers noma amapayipi emishini ezimbonini ezifana ne-petrochemical, metallurgy, shipbuilding, kanye nezimboni zendwangu.Ngezinye izikhathi zisetshenziswa kabanzi ezindongeni zokuhlukanisa embonini yezokwakha, nasekufakeni uphahla lwangaphakathi nodonga kanye nezinye izinhlobo zokushisa okushisayo.Gcina ufudumele.Kodwa-ke, embonini yamandla, imboni ye-petrochemical, imboni yokukhanya, njll., ukufakwa kwe-insulation kanye nezinyathelo zokushisa ezishisayo zamapayipi zisetshenziswa kumapayipi ahlukahlukene, ikakhulukazi amapayipi anezikhala ezincane zokuvuleka.Amapayipi e-rock wool angangeni manzi angasetshenziswa ngokushesha.Inezici ezikhethekile ezifana nokumelana nomswakama, ukuxosha amanzi kanye nokukhipha ukushisa.Ilungele ukusetshenziswa ezindaweni ezinemvula.Inokuxosha amanzi.

2. Uboya bengilazi,
Uboya bengilazi bunezici zokubumbeka okuhle, ukuminyana kwevolumu ephansi, kanye ne-thermal conductivity ephansi.Uboya bengilazi bubuye bukwazi ukumelana nokugqwala okuphezulu kakhulu futhi bunezici ezinhle zamakhemikhali ezindaweni ezigqwala ngamakhemikhali.Izici zokuzivumelanisa nezimo zoboya bengilazi ziwukufakwa kwama-air conditioners, amapayipi okukhipha umoya, ama-boilers namapayipi omusi.

3. I-urethane, i-polyurethane, esetshenziswa kakhulu ekukhiqizeni isitoreji esibandayo, amaloli afakwe esiqandisini noma amabhokisi okugcina amasha.Ingasetshenziswa futhi njengesendlalelo sokushisa ukushisa kwamaphaneli wesemishi lensimbi enombala.Ngezinye izikhathi i-polyurethane isetshenziswa emathangeni e-petrochemical.I-Polyurethane nayo inomsebenzi wokufakwa kwe-thermal kanye nokufakwa okubandayo, futhi isetshenziswa emasimini e-petrochemical kanye ne-metallurgical.Isetshenziswa kabanzi ekuvikelweni kongqimba lwangaphandle lwamapayipi agqitshiwe agqitshwayo angaphansi komhlaba ahlukahlukene.
