Isendlalelo sokufakwa kwamapayipikuphinde kubizwe ngokuthi ungqimba lokufakwa kwamapayipi okushisa, okubhekisela esakhiweni sesendlalelo esisongelwe epayipini elingadlala indima yokulondoloza ukushisa kanye nokufaka ukushisa.Isendlalelo sokufakwa kwamapayipi ngokuvamile sakhiwe ngezingqimba ezintathu: ungqimba olufakwa ngaphakathi, ungqimba oluvikelayo, kanye nongqimba olungangenwa amanzi.Ukufakwa kwamapayipi kwamapayipi kubalulekile futhi kuyayonga.Iqinisekisa ukudluliswa okuvamile koketshezi negesi epayipini, inciphisa ukulahlekelwa kwamandla, yandise impilo yesevisi yepayipi, futhi yonga izinzuzo zezomnotho.Lezi izinzuzo zeukufakwa kwamapayipi.
Ekucubunguleni irabha yamapayipi kanye nokufakwa kwepulasitiki, abasebenzi beNkampani ye-Tekmax baqale balinganise ubukhulu bamapayipi afakwe insimbi, amathangi, njll.Thola irabha edingekayo cishe namapulasitiki nezinye izinto, lungisa, bese ulandela izinyathelo zokuqhuba insimbi. ukwakhiwa kwe-insulation yeshidi bese ugoqa ishidi lensimbi Ebusweni bamapayipi namathangi adinga ukugqunywa, sebenzisa izintambo zensimbi ukuze uzibophe ukuze uvikele isikhumba sensimbi ukuthi singawi.Iyunithi yokwakha nayo idinga ukugoqa ngokucophelela izingxenye eziphakanyisiwe njengamapayipi nezinto zokusebenza ukuze kuqinisekiswe umphumela olindelekile wokufakwa kwe-thermal.
1 I-insulation yamapayipi kanye nemishini kufanele ihlanzwe emiseleni nasemithonjeni yamashubhu, futhi ukufakwa kwe-insulation kungenziwa kuphela uma kungekho monakalo owengeziwe kungqimba lokufakelwa kwinqubo elandelayo.
2 Ngokuvamile, ukufakwa kwamapayipi kufanele kube okufanelekile ekuhlolweni komfutho wamanzi, futhi i-anti-corrosion ingakhiwa kuphela, futhi inqubo ayikwazi ukuhlehliswa.
3 Izinto zokuhlanganisa irabha nepulasitiki akumele zibe nemvula noma zigcinwe ezindaweni eziswakeme uma kungena endaweni.
4 Imfucumfucu esele ngemva kokugcinwa kokushisa kufanele ihlanzwe ithimba elibhekele ukwakha.
5 Ukuze kuncishiswe ukushisa kwamapayipi avele obala, uma imisebenzi yomphakathi ifuthwa, kufanele kube nezinyathelo zokuvimbela ukungcoliswa kongqimba lwe-thermal insulation.
6 Uma kunezimo ezikhethekile ezidinga ukususa ungqimba lokufakelwa ukuze kusetshenziswe ipayipi noma ezinye izinhlobo zomsebenzi kulimaze ungqimba lokufakelwa ngesikhathi sokwakhiwa, kufanele lulungiswe ngesikhathi ngokuvumelana nezidingo zokuqala.
Namuhla, umhleli uzokuchazela izindlela ezimbalwa zokufakwa kwamapayipi ezimbonini.
1. I-polyurethane foam insulation
Kuphrojekthi ye-Shaanxi Pipeline Thermal Insulation Project, ipayipi le-thermal insulation kanye ne-anti-corrosion eligqitshwe ngokuqondile, elibizwa ngokuthi ipayipi-in-pipe, libhekisela epayipini eliyinhlanganisela elimbozwe ngongqimba olulwa nokugqwala, ungqimba lokufakwa kwe-thermal kanye nongqimba olucindezelayo udonga lwangaphandle lwepayipi lensimbi.Ilungele kakhulu izindawo ezinamazinga aphezulu amanzi angaphansi komhlaba.Uma kuqhathaniswa namapayipi endabuko okubeka umsele, inochungechunge lwezinzuzo ezifana nokusebenza okuhle kokufakwa kwe-thermal, i-anti-corrosion, ukusebenza kahle kwe-insulation, impilo ende yesevisi, ukwakhiwa nokufakwa okulula, izinyathelo ezincane, kanye nezindleko eziphansi zobunjiniyela.Isetshenziswe kabanzi ekushiseni okuphakathi, ezokuthuthwa kukawoyela, embonini yamakhemikhali, eziqandisini kanye namaphrojekthi wokuphakelwa kwamanzi ezindaweni zase-alpine.
2. I-phenolic foam insulation
I-phenolic foam insulation iwuhlobo lwepulasitiki eyigwebu etholwe yi-phenolic resin enegwebu.Kunezinhlobo ezimbili zama-resin asetshenziswa ekukhiqizeni igwebu le-phenolic: inhlaka ye-thermoplastic kanye ne-thermosetting resin.Ngenxa yokusebenza kahle kwenqubo ye-thermosetting resin, igwebu le-phenolic lingakhiqizwa ngokuqhubekayo, futhi ukusebenza komkhiqizo kuba ngcono, ngakho-ke izinto ezisetshenziswayo zegwebu le-phenolic zisebenzisa kakhulu inhlaka ye-thermosetting.
3. Irabha ethuthukisiwe nokufakwa kwepulasitiki
Irabha yezinga eliphezulu nepulasitiki inomphumela omuhle wokushisisa ukushisa, futhi ukushuba kokufakwayo okusetshenziselwa ipayipi elifanayo epayipini le-Shaanxi mncane, futhi inani lincane;ngasikhathi sinye, iyimpahla yokufakelwa okushisayo eyakhiwe ngokuphelele, inqubo ilula, futhi intuthuko iyashesha;ngaphezu kwalokho, irabha yezinga eliphezulu nepulasitiki kuluhlaza, kuhambisana nemvelo, futhi kuhlanzekile.Izinto ze-insulation zinemfucuza encane ngesikhathi sokwakhiwa futhi azinangozi empilweni.Ukufakwa kwenjoloba okuthuthukisiwe nokufakwa kwepulasitiki kusetshenziswa kabanzi kakhulu ekufakweni kwamapayipi esiqandisi namapayipi e-condensate ezinhlelweni zesiqandisi se-air-conditioning.
4. I-Polystyrene foam insulation
Ukufakwa kwegwebu le-polystyrene kunokwakheka kwamaseli avaliwe, ukumuncwa kwamanzi aphansi, ukumelana nokushisa okuphansi okuhle, nokumelana okuhle nokuncibilika.Ngakho-ke, isetshenziswa kakhulu emishinini yesiqandisi kanye nemishini yokugcina abandayo, njengeziqandisi, imigudu yomoya obandayo, isitoreji esibandayo, njll. Ngaphezu kwalokho, ngoba igwebu le-polystyrene alinabuthi, alinabuthi, lincane ukumuncwa kwamanzi, ukukhanya emzimbeni. , ukugcinwa kokushisa, ukwenza isikhunta, kanye nokumelana nokugqwala kwe-asidi ne-alkali, ingasetshenziselwa ukulondoloza ukushisa kwamapayipi ngezinjongo ezihlukahlukene.
