Pipe ke eng?

Pipe ke tube e sekoti e nang le sefapano se chitja bakeng sa ho tsamaisa lihlahisoa. Lihlahisoa li kenyelletsa maro, khase, li-pellets, phofo le tse ling. Lentsoe pipe le sebelisoa ha le khetholloa ho tloha ho tube ho sebetsa ho lihlahisoa tsa li-tubular tsa litekanyo tse atisang ho sebelisoa bakeng sa tsamaiso ea liphaephe le lipeipi. Sebakeng sena sa marang-rang, liphaephe tse tsamaellanang le litlhoko tsa boholo ba:ASME B36.10Pipe ea tšepe e cheselitsoeng le e se nang seamless leASME B36.19Ho tla buisanoa ka Pipe ea Stainless Steel.

Pipe kapa Tube?

Lefatšeng la liphaephe, ho tla sebelisoa mantsoe pipe le tube. Pipe ka tloaelo e khetholloa ka "Nominal Pipe Size" (NPS), ka botenya ba lebota bo hlalosoang ke "Nomoro ea Kemiso" (SCH).

Ka tloaelo Tube e hlalosoa ka bophara ba eona ba kantle (OD) le botenya ba lebota (WT), e hlahisoang ka Birmingham wire gage (BWG) kapa ka likete tsa inch.

Pipe: NPS 1/2-SCH 40 e esita le ka ntle bophara 21,3 limilimithara le lebota botenya ba 2,77 limilimithara.
Tube: 1/2 ″ x 1,5 e lekana le bophara ba kantle ho 12,7 mm ka botenya ba lerako la 1,5 mm.

Lisebelisoa tsa mantlha tsa li-tube li ho Heat Exchangers, lithapo tsa lisebelisoa le likhokahano tse nyane ho lisebelisoa tse joalo ka li-compressor, boilers joalo-joalo.

Lisebelisoa bakeng sa Pipe

Likhamphani tsa boenjiniere li na le lienjineri tsa lisebelisoa ho tseba lisebelisoa tse tla sebelisoa lits'ebetsong tsa liphaephe. Bongata ba pipe ke ea carbon steel (ho itšetlehile ka tšebeletso) e etsoa ho latela maemo a fapaneng a ASTM.

Pipe ea tšepe ea carbon e matla, e ductile, e cheseha, e khona ho sebetsa, ka mokhoa o utloahalang, e tšoarella 'me e batla e le theko e tlaase ho feta phala e entsoeng ka lisebelisoa tse ling. Haeba pipe ea carbon-steel e ka finyella litlhoko tsa khatello, mocheso, ho hanyetsa kutu le bohloeki, ke khetho ea tlhaho.

Pipe ea tšepe e entsoe ka tšepe e entsoeng ka tšepe le ductile-iron. Lisebelisoa tsa mantlha ke tsa metsi, khase le likhoele tsa likhoerekhoere.

Peipi ea polasetiki e ka sebelisoa ho fetisa maro a matla a senyang, 'me e bohlokoa haholo bakeng sa ho sebetsana le likhase tse senyang kapa tse kotsi le ho hlapolla li-mineral acid.

Lipeipi tse ling tsa Metals le Alloys tse entsoeng ka koporo, loto, nickel, koporo, aluminium le litšepe tse fapaneng tse sa hloekang li ka fumaneha habonolo. Lisebelisoa tsena li batla li le theko e boima 'me hangata li khethoa ka lebaka la ho hanyetsa ho hoholo ha tsona ho lik'hemik'hale tsa ts'ebetso, ho fetisa mocheso o motle, kapa ka lebaka la matla a tsona a tsitsitseng mocheso o phahameng. Li-alloys tsa koporo le tsa koporo ke tsa setso bakeng sa mela ea lisebelisoa, ho lokisa lijo le lisebelisoa tsa Heat Transfer. Litšepe tse sa hloekang li ntse li sebelisoa ka ho eketsehileng bakeng sa tsena.

Pipe e nang le line

Lisebelisoa tse ling tse hlalositsoeng ka holimo, li kopantsoe ho etsa mekhoa ea liphaephe tse nang le mela.
Ka mohlala, peipi ea tšepe ea carbon e ka kenngoa ka hare ka thepa e khonang ho mamella tlhaselo ea lik'hemik'hale e lumella hore e sebelisoe ho tsamaisa maro a senyang. Linings (Teflon®, ka mohlala) li ka sebelisoa ka mor'a ho etsa liphaephe, kahoo hoa khoneha ho etsa li-spools tsa liphaephe pele ho lesela.

Likarolo tse ling tsa ka hare li ka ba: likhalase, li-plastiki tse fapa-fapaneng, konkreite joalo-joalo, le liaparo, joaloka Epoxy, Bituminous Asphalt, Zink joalo-joalo li ka thusa ho sireletsa phala e ka hare.

Lintho tse ngata li bohlokoa ho khetholla thepa e nepahetseng. Ntho ea bohlokoa ka ho fetisisa ho tsena ke khatello, mocheso, mofuta oa sehlahisoa, litekanyo, litšenyehelo joalo-joalo.
