Kutanga kwegore rino, takatanga kutengesa zvakasiyana-siyana zvemapaipi esimbi nhema uye mafittingsmuchitoro chedu chendaneti. Kubva ipapo, takadzidza kuti vatengi vazhinji vanoziva zvishoma nezve iyi premium zvinhu. Muchidimbu, mapaipi ematare matema ndeimwe yeakanakisa sarudzo kune aripo gasi pombi. Iyo yakasimba, iri nyore kuisa, inodzivirira corrosion uye inochengetedza chisimbiso chisina mhepo. Iyo yakasviba coating inobatsira kudzivirira ngura.

Pombi yesimbi nhema yaimboshandiswa papombi dzemvura, asi kubva pakauya mhangura, CPVC nePEX yave kunyanya kufarirwa negasi. Iyo isarudzo huru yekupisa mafuta nekuda kwezvikonzero zviviri. 1) Yakasimba, 2) Zviri nyore kuisa pamwechete. Kungofanana nePVC, simbi nhema inogoneka inoshandisa hurongwa hwepombi uye mafittings akabatanidzwa pamwechete nekomboni, pane welding. Pasinei nezita rayo, mapaipi ematare madema anogadzirwa kubva kune yakaderera-giredhi "low carbon steel" compound. Izvi zvinozvipa zviri nani kusaita ngura pane zvechinyakare simbi pombi.

Sezvo iyi positi iri pamusoro pemapaipi ematare matema uye zvigadziriso, tichanyura mune mamwe maficha uye maitiro. Zvakakosha kuva neruzivo panyaya dzepombi dzepamba pako.

"Simbi nhema" izwi rinowanzoreva rudzi rwesimbi yakavharwa nhema, asi kune marudzi mazhinji akasiyana epombi yesimbi nhema. Dambudziko guru neizvi nderekuti mapaipi ese esimbi nhema anoomerera kune mashoma mashoma. Nekudaro, ese ari maviri akagadzirirwa kubata gasi rechisikigo uye propane magasi, ayo anowanzo kuchengetwa ari pasi pe60psi. Kana yakaiswa nemazvo, pombi yesimbi nhema inofanirwa kusangana nezviyero zvekuvimbisa kudzvanywa kweinenge 150psi.

Simbi nhema yakasimba kupfuura chero pombi yepurasitiki nekuti yakagadzirwa nesimbi. Izvi zvakakosha nekuti kubuda kwegasi kunogona kuuraya. Muchiitiko chekudengenyeka kwenyika kana moto, kuwedzera uku kunogona kukonzera magasi anouraya kuti abude mumba mese.

Black iron pombi tembiricha giredhi
Mapaipi esimbi anogadzika matema ane simba zvakare kana zvasvika pamatembiricha. Nepo panonyungudika pombi dzesimbi nhema dzichikwanisa kudarika 1000F (538C), tepi yeteflon yakabata majoini pamwe chete inogona kutanga kutadza kutenderera 500F (260C). Kana tepi yekuisa chisimbiso ikakundikana, kusimba kwepombi hakuna basa nekuti gasi rinotanga kubuda nemujoini.

Sezvineiwo, teflon tepi yakasimba zvakakwana kutsungirira chero tembiricha inokonzerwa nemamiriro ekunze. Muchiitiko chemoto, njodzi huru yekukundikana inomuka. Asi munyaya iyi, vagari veimba chero ipi zvayo kana bhizinesi vanofanira kunge vatova kunze kana gasi rinokundikana.

Kuisa seiBlack Iron Pipe
Imwe yemabhenefiti makuru eblack iron piping ndeye kusarongeka kwayo. Izvi zvinoreva kuti inogona kukwizwa pasina simba.Threaded pipeiri nyore kushandisa nekuti inogona kukwizwa mukati mekukodzera pasina kuita welded. Sezvinei nechero system ine tambo dzekubatanidza, mapaipi esimbi nhema uye mafittings zvinoda Teflon yekuisa chisimbiso tepi kuti igadzire chisimbiso chisina mhepo. Sezvineiwo, yekuisa chisimbiso tepi uye duct pendi hazvidhure uye zviri nyore kushandisa!

Kuunganidza simbi yakasviba gasi system inoda unyanzvi hushoma uye kugadzirira kwakawanda. Dzimwe nguva mapaipi anofanoiswa shinda kune hurefu chaihwo, asi dzimwe nguva anofanirwa kutemwa nekuiswa shinda nemaoko. Kuti uite izvi, unofanirwa kubata hurefu hwepombi muvhavha, ucheke kusvika pakureba nemucheki wepombi, uye wozoshandisa tambo yepombi kugadzira tambo pamagumo. Shandisa mafuta akawanda ekucheka shinda kudzivirira kukuvadza tambo.

Kana uchibatanidza hurefu hwepombi, imwe mhando ye sealant inofanira kushandiswa kuzadza maburi pakati peshinda. Nzira mbiri dze thread sealant ishinda tepi uye pendi yepombi.

Maitiro ekushandisa thread tepi
Thread tepi (inowanzonzi "teflon tape" kana "PTFE tepi") inzira iri nyore yekusunga majoini pasina kukanganisa. Kushandisa kunotora masekonzi chete. Putira tepi yeshinda kutenderedza tambo dzekunze dzepombi. Kana uri kutarisa kumagumo kwepombi, zviputire newachi. Kana ukaiputira pakatarisana newachi, kuita kwekupuruzira pakukodzera kunogona kusundira tepi kubva panzvimbo.

Putira tepi ichitenderedza shinda dzechirume katatu kana kane, wobva wazvikochekera pamwe chete zvakasimba neruoko. Shandisa chipanera chepombi (kana seti yezvipanera zvepombi) kuti uwedzere kutendeuka kuzere. Kana mapaipi uye mafittings akanyatsosimbiswa, anofanirwa kukwanisa kumira kanenge 150psi.

Nzira yekushandisa pendi yepombi
Pendi yepombi (inozivikanwawo se "joint compound") chisimbiso chemvura chinopinda pakati peshinda kuchengetedza chisimbiso chakasimba. Pendi yepombi yakanaka nekuti haimboomese zvachose, ichibvumira majoini asina kuvharwa ekugadzirisa nekugadzirisa. Imwe yakaderera ndeyekuti inogona kuve yakashatisa sei, asi kazhinji pendi yedhiraivha yakakora zvakanyanya kuti idonhe zvakanyanya.
