Ukuqala kobusika kudlulile, futhi izinga lokushisa lihle kancane kancane, ikakhulukazi ezindaweni ezisenyakatho. Izinga lokushisa liphansi ebusika, nokuthi ungagcina kanjani izinga lokushisa njalo ngesikhathi sokuhamba ngesiteleka selibe yinkinga kuwo wonke umuntu. Namuhla, noBobth uzokhuluma nawe mayelana nokukhethwa kwezinto zokufakwa kwepayipi le-Steam Pipeline.
Yize kunezinto eziningi zokufakelwa, izinto ezahlukene zinokusebenza okuhlukile kuhlelo lokusebenza. Izinto zokufakwa ezisetshenziswa kumapayipi e-Steam zikhethekile impela, kepha yimiphi impahla yokufakelwa esetshenziselwa amapayipi e-Steam? Ngasikhathi sinye kufanele futhi wazi ukuthi yini izinto zokufakwa kwamapayipi we-Steam, ukuze ukhethe kangcono ukwaziswa okuphezulu.
Yiziphi izinto zokufakwa ezisetshenziselwa amapayipi e-Steam?
1. Ngokusho kwe-athikili 7.9.3 yekhodi ye-GB50019-2003 "yokuthola umoya kanye nokukhetha umoya", ukubekwa phambili kufanele kunikezwe izinto zokuvuselelwa kwemishini, ukumunca amanzi aphansi, nobuningi bomsindo ophansi, nomnotho ophansi. Izinto ezisebenza kahle; Izinto zokwehlukanisa izinto kufanele zingabi nezinto zokwakha ezivuthayo ezingapheli noma zelangabi; Ubukhulu besendlalelo sokufakwa kwepayipi kufanele bubalwe futhi bazimisele ngokuya ngobukhulu bezomnotho ku-GB8175 "ukuklanywa kwemishini kanye nokufakwa kwamapayipi" ngesikhathi sokushisa.
2 Yikuphi okufanele ukukusebenzisa kufanele kubhekwe njengokususelwa kubulukhuni bepayipi lesistimu kanye nentengo yezinto zokufaka. Ngokuvamile, izinto zokufakwa ezisetshenziswa ohlelweni kufanele zifane.
3. Kulezi zinsuku, ukufakwa okujwayelekile okushisayo kusebenzisa izinto ezinzima zokufakwa okushisayo okufana ne-cork noma i-polystyrene esetshenzisiwe ngaphambi kwesikhathi. Ngoba ukusetshenziswa kwezinto ezisetshenzisiwe zokufakwa kwezingu-invality ukufakwa kwe-thermal kuyinto elula ekwakheni futhi umphumela wokufakelwa okushisayo ungcono kunalokho okusetshenzwe esizeni, ngakho-ke kusetshenziswa kabanzi. Kodwa-ke, ngalolu hlobo lwesendlalelo esihlanganisiwe sokufakwa, uma ungqimba lwe-varor burrier lungalashwa kahle, umphunga wamanzi emoyeni uzongena ongqimbeni lokufakwa kwezikhala, ngaleyo ndlela ebhubhisa ukusebenza kwesendlalelo sokufakelwa.
Yiziphi izinto zokufaka amapayipi e-Steam?
1. Ipayipi lezinyosi lamadwala,
Amapayipi e-Rock Wool asetshenziselwa kakhulu ukufakwa okushisayo kwama-boilers noma amapayipi emishini ezimbonini ezinjenge-petrochemical, metallurgy, izimboni zezindwangu. Kwesinye isikhathi zisetshenziswa kabanzi ezindongeni zokwahlukanisa embonini yezokwakha, kanye nophahla lwangaphakathi nokufakwa kodonga kanye nezinye izinhlobo zokufakelwa okushisayo. Gcina ufudumele. Kodwa-ke, embonini yamandla, imboni ye-petrochemical, imboni ekhanyayo, njll. Amapayipi e-waterproof rock wood angaqalwa ngokushesha. Inezakhiwo ezikhethekile njengokumelana nomswakama, ukuphendulwa kwamanzi kanye nokushibilika kokushisa. Ilungele ukusetshenziswa ezindaweni ezinemvula. Kunokuphazanyiswa kwamanzi.
2. Uboya bengilazi,
I-Glass Wool inezimpawu zokwakheka okuhle, ubukhulu bevolumu ephansi, kanye nokusebenza okushisayo okuphansi. Uboya be-Glass nabo banokumelana kakhulu nokuqina okuphezulu futhi banezakhiwo ezinhle zamakhemikhali ezindaweni ezinamakhemikhali. Izici eziguqukayo zovolo wengilazi zizokwenziwa kwezimo zomoya, amapayipi okuphekela phansi, ama-boilers kanye namapayipi e-Steam.
3. Urethane, polyurethane, esetshenziswa kakhulu ekukhiqizweni kwezitoreji ezibandayo, amaloli aqandisiwe noma amabhokisi amasha wokugcina. Ingasetshenziswa futhi njengoba ungqimba lokushisa lokushisa lwamaphaneli we-sandwich yensimbi yombala. I-polyurethane kwesinye isikhathi isetshenziswa emathangini ase-petrochemical. I-Polyurethane futhi inomsebenzi wokufakelwa okushisayo kanye nokufakelwa okubandayo, futhi isetshenziswa emasimini ase-petrochemical neyensimbi. Kusetshenziswa kabanzi ekuvikelweni kwengqimba yezangaphandle kwangaphandle kwenhlanganisela ehlukahlukene engaphansi komhlaba engcwatshwe ngokuqondile.
