Yintoni umbhobho wentsimbi edityanisiweyo

Ihlabathi eliguquguqukayo lemibhobho yentsimbi edityanisiweyo: umbono obanzi

Ekwakhiweni nasekuveliseni, umbhobho wensimbi odibeneyo uye waba sisiseko sembombo, ukudibanisa amandla, ukuqina kunye nokuguquguquka. Le mibhobho yenziwa ngokudibanisa iipleyiti zentsimbi ezisicaba okanye imicu yentsimbi, nto leyo ebangela ukuba kubekho imveliso enokwenziwa ngokwezifiso kwiinkcukacha ezahlukeneyo kunye nokusetyenziswa. Eli nqaku libonelela ngokujongwa okunzulu kwiimpawu, ububanzi bobukhulu, kunye nokusetyenziswa okuphambili kombhobho wensimbi odibeneyo, ngokugxininiswa ngokukodwa kwi-ASTM A53 (ASME SA53) inkcazo yepayipi yensimbi yekhabhoni.

Yintoni umbhobho wentsimbi odityanisiweyo?

Imibhobho yentsimbi edityanisiweyo yenziwa ngokubumba iipleyiti zentsimbi ezisicaba zibe yimilo yecylindrical kwaye emva koko ziwelding ecaleni kwemithungo. Inkqubo inokuvelisa imibhobho yobukhulu obuhlukeneyo kunye nobukhulu, okwenza ukuba bafanelekele uluhlu olubanzi lwezicelo. Inkqubo ye-welding ayigcini nje ukwandisa ingqibelelo yesakhiwo sombhobho, kodwa ivumela ukusetyenziswa ngokufanelekileyo kwezinto, ukunciphisa inkunkuma kunye neendleko.

Uluhlu lwesayizi yombhobho wentsimbi edityanisiweyo

Imibhobho yentsimbi edityanisiweyo iyafumaneka ngokobukhulu obahlukeneyo ukuhlangabezana neemfuno ezahlukeneyo zoshishino. Le mibhobho ifumaneka ngokobukhulu obususela kwi-NPS 1/8” ukuya kwi-NPS 26 ngokuhambelana nenkcazelo ye-ASTM A53 egquma umbhobho wentsimbi ongenamthungo, odiphuliweyo omnyama kunye nentsimbi ediphu eshushu. Olu luhlu olubanzi luvumela ukuyila kunye nokuguquguquka kwesicelo, ukulungiselela izicelo ezivela kwimibhobho emincinci Iimfuno ezahlukeneyo ukusuka kubunjineli ukuya kumaziko amakhulu amashishini.

Inkqubo yoMbhobho weNominal (NPS) yindlela esemgangathweni yokulinganisa ubungakanani bombhobho, apho ubungakanani bubhekiselele kumlinganiselo wangaphakathi wombhobho. Umzekelo, umbhobho we-NPS 1/8” unobubanzi bangaphakathi obumalunga ne-0.405 i-intshi, ngelixa umbhobho we-NPS 26 unobubanzi obungaphezulu obuyi-intshi ezingama-26. Olu luhlu luqinisekisa ukuba umbhobho wensimbi odibeneyo unokuhlangabezana neemfuno ezithile zeeprojekthi ezahlukeneyo, nokuba zibandakanya ukuhanjiswa kwamanzi , ukuxhaswa kwesakhiwo okanye ezinye izicelo.

Usetyenziso oluphambili lwemibhobho yentsimbi edityanisiweyo

Imibhobho yentsimbi edityanisiweyo isetyenziswa ngokubanzi kumashishini amaninzi ngenxa yokusebenza kwawo okuqinileyo kunye nokuguquguquka. Nazi ezinye izicelo eziphambili:

1. Ulwakhiwo noLwakhiwo lwezicelo:Imibhobho yentsimbi edityanisiweyo isetyenziswa ngokubanzi ukuxhasa ulwakhiwo kwizakhiwo. Ngenxa yomlinganiselo wabo ophezulu wokuqina kobunzima, bahlala besetyenziselwa ukwakha izakhelo, iibhulorho, kunye nezinye iiprojekthi zeziseko zophuhliso.

2.Ishishini leoli negesi:Ishishini leoli negesi lixhomekeke kakhulu kwimibhobho yentsimbi edityanisiweyo ukuthutha i-oyile ekrwada, igesi yendalo, kunye nolunye ulwelo. Iimpawu ze-ASTM A53 ziqinisekisa ukuba le mibhobho inokumelana noxinzelelo oluphezulu kunye neendawo ezinobungozi, ezibenza zibe zilungele kolu shishino.

3. Ubonelelo lwaManzi kunye noSasazo:Umbhobho wensimbi odibeneyo usetyenziswa ngokuqhelekileyo kwiinkqubo zokubonelela ngamanzi kamasipala. Ukomelela kwazo kunye nokumelana nomhlwa kuzenza zilungele ukuhambisa amanzi okusela kunye namanzi amdaka.

4. Izicelo zokuVelisa kunye nezoShishino:Kwimveliso, umbhobho wentsimbi odityanisiweyo usetyenziswa kwiinkqubo ezahlukeneyo, kubandakanywa ukuveliswa koomatshini, izixhobo kunye namanye amacandelo oshishino. Ukuguquguquka kwabo kuvumela ukwenza ngokwezifiso ukuhlangabezana neemfuno ezithile zokuvelisa.

5. Umzi mveliso weemoto:Umzi-mveliso weemoto usebenzisa imibhobho yentsimbi edityanisiweyo ukuvelisa iinkqubo zokuphuma, izixhobo ze-chassis, kunye nezinye izinto ezibalulekileyo. Amandla kunye nokuthembeka kwale mibhobho kubaluleke kakhulu ekuqinisekiseni ukhuseleko kunye nokusebenza kwesithuthi.

6. Iinkqubo zeHVAC:Imibhobho yentsimbi edityanisiweyo ikwasetyenziswa kwiinkqubo zokufudumeza, zokuphefumla, kunye nezomoya (HVAC). Zisetyenziselwa i-ductwork kunye nemigudu yokubonelela ukuhamba komoya okusebenzayo kunye nokulawula ukushisa kwizakhiwo zokuhlala kunye nezorhwebo.

Ukuququmbela

Umbhobho wentsimbi odityanisiweyo uyinxalenye ebalulekileyo yeshishini ngalinye, enika amandla, ubuninzi kunye nokusebenza kakuhle kweendleko.
