Ngakhale kukula ndichinthu chofunikira posankha ma flanges, zigono, ndi zigawo zina zamapaipi anu, malekezero a chitoliro ndichinthu chofunikira kwambiri kuti muwonetsetse kukwanira, chisindikizo cholimba, komanso magwiridwe antchito abwino.

Mu bukhuli, tiwona masinthidwe osiyanasiyana a mapaipi omwe amapezeka, momwe amagwiritsidwira ntchito nthawi zambiri, ndi zinthu zomwe muyenera kuziganizira posankha malekezero enaake.

POMBO WAWONSE AMATHA

Mtundu wa mapeto a chitoliro osankhidwa udzatsimikizira momwe zimagwirizanirana ndi zigawo zina ndi zomwe zimagwiritsidwa ntchito ndi zigawo zomwe chitolirocho chili choyenera kwambiri.

Mapeto a chitoliro amagwera m'magulu anayi:

• Plain Ends (PE)
• Mapeto a Threaded (TE)
• Bevelled Ends (BW)
• Zolumikizana Zamakina Zomangika kapena Mapeto Ophwanyidwa

Chitoliro chimodzi chingakhalenso ndi mitundu ingapo yomaliza.Izi nthawi zambiri zimayikidwa mu kufotokozera kwa chitoliro kapena chizindikiro.

Mwachitsanzo, chitoliro cha 3/4-inch SMLS Schedule 80s A/SA312-TP316L TOE chitoliro chili ndi ulusi mbali imodzi (TOE) ndipo ndi yomveka mbali inayo.

Mosiyana, chitoliro cha 3/4-inch SMLS Schedule 80s A/SA312-TP316L TBE chitoliro chili ndi ulusi mbali zonse ziwiri (TBE).

ZOGWIRITSA NTCHITO NDI ZOGANIZIRA PAPOSI (PE).

Mapaipi a PE amatha kumapeto kwake amadulidwa pamadigiri 90 kupita ku chitoliro kuti chikhale chophwanyika, ngakhale kutha.

Nthawi zambiri, mapaipi osavuta amagwiritsidwa ntchito kuphatikiza ma slip-on flanges ndi socket weld fittings ndi flanges.

Masitayelo onsewa amafunikira kuwotcherera kwa fillet kumbali imodzi kapena mbali zonse ziwiri za cholumikizira kapena flange komanso m'munsi mwa nsonga kapena flange.

Ngati kuli kotheka, chigwacho chiziikidwa ⅛” kuchokera pomwe chitoliro chimakhala kuti chiwotchere chiwotcherera.

Izi zimawapangitsa kukhala abwino kwa makina ang'onoang'ono a mapaipi.

ZOGWIRITSA NTCHITO NDI ZOGANIZIRA ZA PIPI (TE) ZOPHUNZITSIDWA

Amagwiritsidwa ntchito pamapaipi okhala ndi mainchesi atatu kapena ochepa, mapaipi a TE amalola chisindikizo chabwino kwambiri.

Mapaipi ambiri amagwiritsa ntchito muyezo wa National Pipe Thread (NPT) womwe umalongosola ulusi wokhotakhota womwe umagwiritsidwa ntchito pa chitoliro ndi taper yodziwika kwambiri yoyezera 3/4-inch pa phazi.

Taper iyi imalola kuti ulusiwo uzikoka mwamphamvu ndikupanga chisindikizo chogwira mtima.

Komabe, kulumikiza ulusi pa chitoliro cha TE moyenera ndikofunikira kuti tipewe kuwononga mapaipi, zopangira, kapena ma flanges.

Kuphatikizika kosayenera kapena kuphatikizika kungayambitse kukwiya kapena kugwidwa.

Zikapanda kugwiritsidwa ntchito, kuwonongeka kwa ulusi kapena chitoliro kungathe kuchepetsa kukana kwa dzimbiri ndi zinthu zaukhondo - zifukwa ziwiri zodziwika posankha chitoliro chachitsulo chosapanga dzimbiri.

Mwamwayi, kupewa nkhawazi nthawi zambiri kumakhala kosavuta monga kukonzekera ulusi musanasonkhanitse.

Tikupangira ndikugulitsa tepi yosindikiza ulusi wosapanga dzimbiri wa Unasco.

Tepiyo imapangidwa ndi ufa wa faifi tambala, imasunga pamwamba pa ulusi wamphongo ndi wamkazi kumalekezero padera kwinaku ikuphatikizanso mafuta olumikizirana kuti asonkhanitse mosavuta ndi kupasuka.

BEVELLED END (BW) NTCHITO NDI ZOGANIZIRA PAPASI

Zogwiritsidwa ntchito ndi ma buttwelding, zoyikira mapaipi a BW nthawi zambiri zimakhala ndi bevel ya 37.5-degree.

Ma bevel awa nthawi zambiri amagwiritsidwa ntchito ndi opanga pamanja kapena kudzera munjira zodziwikiratu kuti zitsimikizire kusasinthika.

Izi zimathandiza kuti machesi wangwiro ndi BW chitoliro zovekera ndi flanges ndi kuwotcherera mosavuta.

ZOGWIRITSA NTCHITO NDI ZOGANIZIRA PAPOSI

Mapaipi omangika kapena mapaipi otsekera amagwiritsira ntchito poyambira kapena makina opangidwa kumapeto kwa chitoliro kuti akhazikitse gasket.

Nyumba yozungulira gasket ndiye yomangika kuti iteteze kulumikizana ndikuwonetsetsa kuti chisindikizo chokwanira komanso magwiridwe antchito.

Kapangidwe kameneka kamalola kuti disassembly ikhale yosavuta ndi chiopsezo chochepa cha kuwononga zigawo za mapaipi.

ZOCHITIKA ZONSE ZOKHUDZA ZOKHUDZA ZOKHUDZA NDIPONSO MFUNDO

Kulumikizana kwa mapaipi omwe amagwiritsidwa ntchito popanga nsonga zamapaipi - nthawi zambiri amatanthauzidwa pogwiritsa ntchito mawu achidule.

Nthawi zambiri, chilembo choyamba chimasonyeza mtundu wa mapeto omwe amagwiritsidwa ntchito pamene zilembo zotsatirazi zimakudziwitsani zomwe zatsirizidwa.
