Ukubukelwa kwamapayipi

I-Joint idalwe ngokubhidliza ama-flanges amabili komunye nomunye futhi ayibetha ngokuwasebenzisa ngokusebenzisa ama-gaskets ahlukahlukene. Ama-Flanges ajwayele ukwenziwa nge-aluminium, ithusi, ithusi noma insimbi yekhabhoni. Izinto ezikhetheke kakhulu zezicelo ezijwayelekile ze-Flange yinsimbi ebiyelwe i-carbon. Ngaphezu kwalokho, ama-flanges angabekwa ngaphakathi ngaphakathi nezinhlobo ezahlukene ze-linings. Imvamisa, impahla ye-flange ikhethiwe njengento efanayo ne-Pipe Material. Lokhu kukhethwa kwezinto okwenziwayo ukuze kuvikeleke ubungozi bokugqwala kwe-galvanic. Ukukhethwa okufanele kwezinto ezibonakalayo kwama-flanges kunqunywa ngokuya ngamazinga we-ASTM A-182.

Ukucaciswa kwezinhlobo ze-Flange kwenziwa nge-ASME B16.5 Standards. Ngakho-ke ama-flanges ahlukaniswa ngokuthi; Intamo ye-Weld, ukushelela, iSocket Weld, i-Lap-Joint-Joint. Ama-flanges e-weld entamo kulula ukubona. Ukuqhuma kwe-cylindrical okunokwanda kancane kancane kuxhumeke engxenyeni eyinhloko eyize.

I-cylindrical bulge inciphisa ukusetshenziswa kwe-flange ezimweni ezimbi kakhulu njengokuthi; amazinga okushisa aphakeme noma umoya ophakeme ocindezelwe. Lawa ma-flanges afakwa emapayiphu noma kumapayipi ngokusebenzisa i-butt-welding enika amandla ukulungiswa okuphelele komzimba. Ama-flanges ashelelayo nawo ajwayelekile ukusetshenziswa ngenxa yezindleko zawo eziphansi. Azidingi ukuqeda ngokweqile indawo ye-Welve Coud Flanges.

Ngakho-ke, ukulungiswa kwama-flanges ashelelayo-on kulula. Kodwa-ke, amandla ama-flanges ashelelayo anama-flanges amabili e-Weld Coud Flanges, ngaphansi kwengcindezi yangaphakathi ngenxa yokugeleza. Okunye okubi kwama-flanges okushelelayo ukuthi kungukuthi izingxenyana ezingenzeki ukuthi zilungise i-flange ku-elbow noma zilungise i-flange ku-tee ngoba indawo yokugcina ye-slip-on the slittings ayiqondile. Iqembu lesithathu le-Flange i-Socket Weld Flanges. Lawa ma-flanges asetshenziselwa amapayipi amancane okumele athele izingcindezi eziphakeme. Amandla we-Socket Weld Flenges ngokubhekisisa izingcindezi zangaphakathi alingana nokushelela-ama-flanges.

Kodwa-ke, amandla abo okukhathala aphakeme kunama-flanges ashelelayo. Inkinga enkulu yeSocker Weld Flanges yingozi yokugqwala. Igebe phakathi kwe-flange nokufaneleka noma ipayipi kufanele ligcinwe ngaphambi kokushiswa. Uketshezi olulimazayo noma umswakama lungathola kulezi zindawo zokukhosela. Ngakho-ke, lesi sibonisi esinamanzi aqinile singadala ukugqwala emzimbeni.

Kunamuhla i-Merland emhlabeni, amapayipi ajwayelekile kakhulu cishe kuzo zonke izinhlelo zokusebenza ezihambisa noma yiluphi uhlobo oluwuketshezi noma lwe-gaseous. Lezi zinto eziwuketshezi noma ze-gaseous ziyageleza ohlelweni lwepayipi ngezingcindezi ezahlukahlukene namazinga okushisa. Ngakho-ke, amasistimu wepayipi ahlushwa izingcindezi ezedlulele ezikhiqizwa ingcindezi kanye nokushisa.

Ama-flanges ahlangene ane-lap anesimo esilinganayo esifana neSocket Weld Flenges ngaphandle kwegebe le-Weld. Ngakho-ke, ukusetshenziswa kwabo kuzinhlelo zokusebenza ezingadala ukugqwala kunzuzo. Olunye uhlobo lwe-flange amafulethi afakwe intambo. Ama-flanges ahlanganisiwe asiza kakhulu kwizicelo ezithile ngoba azidingi ukuthutha ukulungiswa.

Ngakho-ke, uhlelo lwepayipi kumele lwenzelwe futhi lukhiqizwe ngendlela engaphatha ukucindezelwa okubangelwayo ngesikhathi sokuhamba kwezinto eziwuketshezi noma ze-gaseous. Ezinye izikhungo (izitshalo zamandla, ukufucuza kukaphethiloli, njll.) Zidinga izinhlelo ezinde nezinkulu eziyinkimbinkimbi zamapayipi. Ngaphezu kwalokho, lezi zinhlobo zezakhiwo ziphatha izinkinga ngenxa yesikhala esilinganiselwe sokusebenza.

Ama-Flanges ayimpumputhe ukuhlukaniswa kokugcina kwesigaba se-flange. Zisetshenziswa njengezindela zokugcina zama-valves amapayipi noma amaphampu. Njengoba ama-flanges ayimpumputhe asetshenziswa njengezithiyo ngokumelene nokugeleza kwamanzi, ziyizingxenye eziphakeme kakhulu ze-flange systems.

Uhlelo lwepayipi kumele lukhiqizwe futhi lubekwe kude nendawo yendawo. Lezi zindawo eziyinkimbinkimbi zisebenzisa amapayipi spool ngezilinganiso ezihlukile nezinto ezahlukahlukene. Amapayipi spools yizingxenye ezenzelwe ukuqalwa okubandakanya amapayipi, ama-flanges, kanye nokufakelwa. Ukufakwa kwamapayipi yizakhi ezixhuma inethiwekhi eyinkimbinkimbi yepayipi. Ngaphezu kwalokho, ukufakwa kwamapayipi kuguqula ama-systems e-piping noma ubukhulu noma ubukhulu. Kunezinhlobo ezahlukahlukene zezakhi ezifanele kepha zingahlukaniswa ngamaqembu amathathu ngamaqembu amathathu okuyi-elbows Tees nama-Flanges.

Inqubo yokukhiqiza ye-Pip Spools inezigaba eziningana. Zonke izigaba zisetshenziswa ngezinhloso ezithile kanye ne-array phakathi kwezigaba zinombala. Ngakho-ke, izinyathelo zokukhiqiza zingahlukaniswa kumaka, ukusika, ukulingana, ukufudumala, nokupenda.

Ama-elbows ngokuvamile asetshenziselwa ushintsho ekuqondisweni kokugeleza. Izinhlelo ezijwayelekile ze-elbow zingashintsha i-angle yokugeleza ngo-180¡Ã, 90¡Ã noma i-45¡Ã noma i-45¡Ã noma i-45¡Ã. Uhlelo lwe-180¡Ã elbow lubizwa nangokuthi ¡® ®return bend¡¯. Amasistimu we-elbow angahlukaniswa abe ngamaqembu amabili ayi-butt weld elbows kanye nokunciphisa ama-elbows. I-butt-welded elbows iyizakhi ezivame kakhulu futhi ezifiselekayo.

Njengokuqala kokukhiqiza, zonke izinto kufanele zimakwe ukuze zikhulise ukubonwa kwezinto zokwakha. Umsebenzi wokumaka ungaqaliswa ngenxa yenombolo ethile yezakhi. Ngaphezu kwalokho, zonke izilinganiso zepayipi amapayipi kumele zikubekele zona. Ukulandelwa kwezakhi akumele kungcolise impahla ngaphandle kokulandela kungasabela ngezinto ezibonakalayo futhi lokhu kungadala izinkinga ezisusiwe.

Uhlelo lonke lwe-butt Weld kumele lukhiqizwe ngemikhawulo ebekiwe. Ama-elbows we-90¡Ã butt Welded akhiqizwa ukwenza i-angle ye-perpendicular kuyo yonke indlela. Zingahlinzekwa njengemisebe emifushane nende. Ukulungiswa okufunekayo kanye nokugxila okulungile phakathi kwezakhi kungagcinwa nge-radius ebalwa ngempela.

Ngakho-ke irediyo ekhethiwe ye-elbow ingabaluleka kakhulu. Olunye uhlobo lwe-elbows lunciphisa ama-elbows. Kulolu hlobo lwe-elbows, ubukhulu bemisebe ye-Centre-Line Radius ilingana nengxenye yosayizi ophakeme wokuphela okukhulu. Ukunciphisa ama-elbows, futhi, gcina ushintsho lwe-90¡Ã flu flow ohlelweni lwepayipi. Ngaphezu kwalokho, ushintsho olungu-180¡Ã0Flow lungagcinwa ngokusebenzisa uhlobo oluthile lokunciphisa i-elbow ebizwa nge-¡®return bends.

Ama-Tees nawo asetshenziselwa ukuguqulwa kwe-angle yokugeleza nokusatshalaliswa kwento egelezayo kungaba esiteshini esisodwa noma ngaphezulu. Tees ingahlukaniswa ngamaqembu amabili aphambili okuyi-butt welded tees kanye ne-socket i-Welded Tees. I-Butt Welded Tees isetshenziswa ukwenza ukusatshalaliswa kwe-perpendicular kokugeleza. Benza amagatsha angu-90¡Ã0¡Ã axhumano ngepayipi futhi asabalalise udaba oluzayo kusuka ku-mainline.

I-Butt Welded Tees ingagcina ukugeleza okuqondile noma ukunciphisa ukugeleza okuncike ohlelweni lwePipeline. Amagatsha anciphisa (anciphisa ama-tees) enza ukuxhumana okuphelele nge-mainline. Imisebe yamazinyo ngokuvamile incane kunomugqa ophambili wokugeleza. Imisebe yama-tees aqondile akhiqizwa ngendlela enemisebe efanayo nomugqa omkhulu wokugeleza.

Ama-tee we-welded we-socket abuye enza i-perpendicular angle phakathi kwemigqa exhunyiwe. Basebenzise izinhlelo zokusebenza ezicindezela kakhulu. Ngokuphikisana neTett Welded Tees, ama-selded telded asetshenziswa kuzinhlelo zokusebenza lapho i-radius yamapayipi ngokuvamile incane. Ama-Tees we-Socket Welded awadingi inqubo ebukekayo ngaphambi kokufudumala. Ngakho-ke, lezi zinhlobo zamashumi amakhethini zithandeka kwezinye izinhlelo zokusebenza lapho amagatsha egatsha kufanele agcinwe ngendlela efanayo ngaphambi nangemva kokushiswa.
