I-Poipe Spools

I-dibane idalwe ngokwenza i-fact ezimbini kwelinye enye kwaye ibatywine ngokusebenzisa iirhasi ezahlukeneyo. Iiflethi zihlala zenziwa nge-aluminium, i-bronze, brass okanye i-carbon sensi. Ezona zinto zikhethwayo kwizicelo zeflethi jikelele yintsimbi yekharbon yekharbon. Ngapha koko, iiflevu zinokungeniswa ngaphakathi neentlobo ezahlukeneyo zelines. Ngokwesiqhelo, izixhobo zeflethi zikhethwe njengezixhobo ezifanayo kunye nezinto zombhobho. Olu khetho lwezixhobo luqhutywa ukwenzela ukuthintela ingozi ye-gavanic. Ukhetho olufanelekileyo lwezinto ezibonakalayo zigqitywe ngokwe-ASTM A-182.

Iiflethi ezidibeneyo ezidibeneyo zinemilo efanayo nesokenty ze-soker ngaphandle kwe-sleld gap. Ngenxa yoko, ukusebenzisa kwabo kwizicelo ezinokubangela ukuba ukhuko luyingenelo. Olunye uhlobo lweflethi yiflethi exutywe. Iiflethi ezicekeceke ziluncedo kakhulu kwizicelo ezithile kuba azifuni ukuba zenzelwa ukulungiswa.

I-tees ye-weltiked ye-weldied yenziwa ngenxa ye-ASTM Asme B16.11 imigangatho. Le migangatho ingenisa kwaye ithathe isigqibo soxinzelelo olufanelekileyo kunye namanqanaba amaqondo obushushu, i-radises kunye nempahla efunekayo yokuveliswa kweenkomo. Ngaphaya koko, iMigangatho ye-B16.11 ivunyelwe kuphela kwikharbon kunye ne-alloy steels. I-tees ye-weltiked ye-welding inokuveliswa ibe ziindidi ezintathu zoxinzelelo. Iklasi yama-3000, iklasi 6000 kunye neklasi ye-9000.

Ke ngoko, ukulungiswa kwe-flip-kwiflethi ye-Slip kulula. Nangona kunjalo, amandla eflethi yelitye lesibini isibini kwisithathu se-WOLD, phantsi koxinzelelo lwangaphakathi ngenxa yokuhamba. Enye into engalunganga yeflethi ye-Slip kukuba inokwenzeka ukuba ikwazi ukulungisa i-flanger ukuya kwi-elbow okanye ilungisa iflethi kwi-tee ngenxa yokuba i-tight ichanekile. Iqela lesithathu leFlanges yi-soker uffexees. Ezi fungers zisetyenziselwa imibhobho emincinci ekufuneka ivelise uxinzelelo oluphezulu. Amandla e-sokere slenges nxamnye noxinzelelo lwangaphakathi alingana ne-Slip-kwiflethi.

Iiflethi zezinto ezisebenza njengesinxibelelanisi phakathi kwemibhobho ephambili, i-valves okanye iimpompo. Elona phelelo libalaseleyo lokusetyenziswa kweflethi ngokulula ngokulula ukucoca kunye nokuhlolwa kwendawo enxulumene neflethi. Iiflethi zihlala ziveliswa ngokusebenzisa iindlela zedysing okanye ezikrolayo. Iinkqubo zeFlanji zenza ihlazo phakathi kwezinto ezahlukeneyo.

Yonke inkqubo ye-Butt ye-LOTL kufuneka iveliswe kunye nezakhiwo ezifundweni. I-90¡ö¡ ye-Weldad Ellows iveliswa ukuba yenze i-angle ye-perperm kuyo yonke indlela. Banokubonelelwa njengamafutshane e-radius. Ukulungiswa okufunwayo kunye nendawo efanelekileyo phakathi kwamacandelo kunokugcinwa ngokusebenzisa irediyo ebalwa ngokwenene.

Kule mihla le moya, imibhobho ixhaphake kakhulu phantse nganye yesicelo esithutha nawuphi na ulwelo okanye isixhobo segesi. Olu luhlu okanye izinto ze-geseous zihamba kwinkqubo yombhobho kunye noxinzelelo olwahlukileyo kunye namaqondo obushushu. Ke ngoko, iinkqubo zemibhobho zibandezeleka kakhulu eziveliswe luxinzelelo kunye nobushushu.

I-tees ye-bott ye-bott inokugcina ukuhamba ngokuthe ngqo okanye ukunciphisa ukuhamba okuthe tyaba kuxhomekeka kwinkqubo yepayina. Amasebe okunciphisa (ukunciphisa i-tees) yenza uqhagamshelo olukhoyo kunye nombala ophambili. I-radius ye-tees ihlala incinci kunomgca ophambili wokuhamba. I-radius ye-tees ethe tye iveliswa ngendlela enee-radias ezifanayo nomgca ophambili wokuhamba.

Inkqubo yemveliso yemibhobho inamanqanaba aliqela. Onke amanqanaba aphunyeziwe kwinjongo ethile kwaye uluhlu oluphakathi kwamanqanaba luvotous. Ke ngoko, amanyathelo emvelisi akwanokwahlulwa ukuba akhawuleze, anqumle, afaneleke, afune, kwaye apeyinti.

Inkqubo yombhobho kufuneka iveliswe kwaye inyuke kude kwindawo yendawo. Ezi ndawo zintsonkothileyo zisebenzisa imibhobho ye-faili enemilinganiselo eyahlukeneyo kunye nezinto ezahlukeneyo. Ii-spools ze-pubile ngamacandelo angekelisiweyo ezibandakanya imibhobho, iiflethi, kunye nezixhobo. Izixhobo zombhobho zizinto eziqhagamshela inethiwekhi ye-pipe entsonkothileyo. Ngaphezulu, izinto zombhobho zitshintsha iinkqubo zokuthintela imibhobho Kukho iintlobo ezahlukeneyo zamacandelo afanelekileyo kodwa zinokwahlula-hlula ngokufutshane ngokuba ngamaqela amathathu aqingqiweyo kunye neeflethi.

Ukucaciswa kweentlobo zefleki zenziwa ngemigangatho ye-AST16.5. Njalo ke ukuhlelwa njenge; Intamo ye-Wold, i-Slip-kwi-sheeke ye-shed, i-geneg-genent, i-theinti eyimfama. Iiflethi ze-WOld zilula kufuneka ziqonde. I-cylindrical bulge kunye ne-radius yanda ngokuthe ngcembe iqhagamshelwe kwilungu eliphambili.

I-cylindrical bulge ikhulule ukusetyenziswa kwe-flange kwiimeko ezigqithileyo ezifana; amaqondo obushushu aphezulu okanye amaqondo aphezulu aphezulu. Ezi funged zidliwayo kwimibhobho okanye imibhobho usebenzisa i-butt-welding eyenza ukulungiswa ngokupheleleyo komzimba. I-slip-kwiflethi yeflethi ixhaphakile kakhulu ngenxa yexabiso labo eliphantsi. Azifuni ukupheliswa komgangatho kakhulu njengeflethi ye-WOLD.

Njengokuqala kwemveliso, onke amacandelo kufuneka aphawulelwe ukuze anyuse iliso kwizinto. Umsebenzi wokumakisha unokumiliselwa ngenxa yenani elithile lamacandelo. Ngapha koko, yonke imilinganiselo ye-spools yombhobho kufuneka iphawulwe kubo. Umkhondo ematyeni awufanelanga ukuba ungcolise izinto ezibonakalayo ezinokuphendula ngento kwaye oku kunokubangela iingxaki ezikhawulezayo.

Nangona kunjalo, amandla awo okudiya aphezulu kuneflethi-kwiflethi. Ingxaki enkulu ye-Soket Helly Fufxes ngumngcipheko wokungasebenzi. Umsantsa phakathi kweflethi kwaye kufanelekile okanye kumbhobho kufuneka ugcinwe ngaphambi kwe-welding. Ulwelo oluhle okanye umswakama unokufumana ezi zikhuselo. Yiyo loo nto, le nto iqinileyo-yolwelo-nye inokubangela ingcolo emzimbeni.

Ke ngoko iredithi ekhethiweyo ye-elbow inokubaluleka kakhulu. Olunye uhlobo lwe-ellows lunciphisa ii-ellows. Kolu hlobo lwe-elbows, ubukhulu be-radius yendawo yeziko Ukunciphisa i-elbows, kwakhona, gcina utshintsho lwendlela yokuqhutywa kwe-90 kwinkqubo yepayipi. Ngapha koko, utshintsho lwe-180 lwe-180 lunokugcinwa ngokusebenzisa uhlobo oluthile lokunciphisa i-elbow ebizwa ngokuba yi-¡®retsturns.

I-tees ikwasetyenziselwa ukutshintsha i-engile yokuhamba kunye nokusasazwa komcimbi oqukuqelayo nokuba ungene kwi-tentenes enye okanye ezingaphezulu. Ii-tees zinokwahlulwa zibe ngamaqela amabini aphambili eziziintethi ze-bot ze-balt kunye nesokisi ye-seldal. I-Tees ye-WelDed isetyenziselwa ukwenza ukuhanjiswa kwendlela yokuhamba. Benza amasebe angama-90¡ ãches uqhagamshelo lombhobho kwaye asasaze umbandela ophelileyo.

I-elbows isetyenziselwa utshintsho kwindlela yokuhamba. Iinkqubo eziqhelekileyo ze-elbow zinokutshintsha i-engile ye-180¡, i-90¡` okanye i-45¡. Inkqubo ye-180 yokukhangela ikwabizwa ngokuba yi-ain ®retter bend¡¯. Iinkqubo ze-elbow zinokuhlelwa zibe ngamaqela amabini apho ii-Bhld zelbows kunye nokunciphisa i-elbows. I-lot-Welbows elbows zezona zinto zixhaphakileyo nezinqwenelekayo.

I-teeked ye-weldake ye-weldied nayo yenza i-angle ye-perperm phakathi kwemigca exhunyiweyo. Basebenzise izicelo zoxinzelelo oluphezulu. Ngokuchasene ne-tees ye-lelt ye-weldad, i-teeked ye-Weldid isetyenziswa kwizicelo apho i-radius yombhobho ngokubanzi incinci. I-teecked ye-welded ye-welding ayifuni inkqubo yokuthambisa ngaphambi kokuba i-welding. Ke ngoko, ezi ntlobo ze-tees zilungile kwezinye iinkqubo apho isebe liphela kufuneka ligcinwe ngendlela efanayo ngaphambi nasemva kwe-welding.
