Ukongeza ekuqinisekiseni ukwakhiwa kweekhemikhali kunye neepropathi zoomatshini, iimvavanyo ze-hydrostatic zenziwa ngenye, kwaye iimvavanyo ezipholileyo zenziwa. . Ukongeza, kukho iimfuno ezithile zoomatshini obuncinci, ubungakanani beenkozo, kunye ne-gesical mayither yombhobho wentsimbi egqityiweyo.
Uvavanyo oluzingisayo:
1. Kwizinto zentsimbi zeemveliso, umvelisi kufuneka enze uvavanyo oluzingisayo. Kumbhobho we-welcrtrice we-welding, ekhutshelwe kuvavanyo loveliso, uvavanyo lwencanca lunokwenziwa kwipleyiti yentsimbi esetyenziselwa ukwenza umbhobho okanye i-piped kumbhobho wensimbi ngqo. Uvavanyo lwenziwe kwimveliso lunokusetyenziswa njengovavanyo lwemveliso.
2. Iityhubhu zovavanyo ziya kukhethwa ngokungacwangciswanga. Xa iimvavanyo ezininzi ziyafuneka, indlela yesampulu iya kuqinisekisa ukuba iisampulu zithathwe zinokumela isiqalo kunye nokuphela komjikelo wonyango wobushushu (ukuba uyasebenza) kunye nozibini iziphelo zetyhubhu. Xa iimvavanyo ezininzi ziyafuneka, ipateni iya kuthathwa kwiityhubhu ezahlukeneyo ngaphandle kokuba isampulu ye-tube eqingqiweyo inokuthathwa kwimisitho yomibini ityhubhu.
I-3. Isampulu yomzimba engenamthungo inokuthathwa nakweyiphi na imeko yolawulo lombhobho; Isampulu yombhobho we-welding kufuneka ithathwe malunga ne-90 ° ukuya kumthungo we-wel, okanye ekukhetheni komenzi. Iisampulu zithathwa malunga nekota yobubanzi bobutya.
4. Akukho nto iphambi kokuvavanywa, ukuba amalungiselelo emodeli afunyenwe ukuba anesiphene okanye kukungabikho kwezixhobo ezingafanelekanga, isampulu inokutsalwa kwaye itshintshwe isampulu eyenziwe kwityhubhu enye.
5. Ukuba uvavanyo lwencasa olumele i-batch yeemveliso azifezekisi iimfuno, umenzi unokuthatha ezinye iityhubhu ezi-3 ukusuka kwi-tubt enye yeetyhubhu zokuhlolwa kwakhona.
Ukuba zonke iisampuli zesampuli zihlangabezana neemfuno, ibhegi yeetyhubhu ifanelekile ngaphandle kwetyhubhu engafakwanga yona kwasekuqaleni.
Ukuba ngaphezulu kwesampulu enye ekuqaleni isampulu okanye iisampulu enye okanye ezingaphezulu zokuhlawula kwakhona azihambelani neemfuno ezichaziweyo, umvelisi unokuhlola ibhegi ye-tubes nganye.
Ibhendi yemveliso engagalekileyo inokuphinda ihlaziywe kwaye inyangwe njengebhendi entsha.
Uvavanyo lokuthelekisa:
1. Uvavanyo lwesandiso luya kuba luvavanyo lokukhala okanye isiphelo sokusika okungaphantsi kwe-63.5mm (2-1 / 2in).
2. Iisampulu zinokusikwa ngaphambi konyango lobushushu, kodwa zixhomekeke kunyango olufanayo lombhobho omelwe ngumbhobho omelwe. Ukuba kusetyenziswa uvavanyo lwe-batch, amanyathelo aya kuthathwa ukuze achonge ubudlelwane phakathi kwesampulu kunye netyhubhu yesampulu. Isiko ngalinye kwi-batch nganye kufuneka lityunyuzwe.
3. Inqaku liya kutshona phakathi kweepleyiti ezimbini ezifanayo. Kwiseti nganye yeesampulu zovavanyo olugudileyo, i-WOLD enye yayicekesiwe kwi-90 ° kunye nenye ecekeceke nge-0 °. Inqaku liya kutshona kude kube kudonga lwe-tube linxibelelana. Ngaphambi komgama phakathi kweepleyiti ezifanayo zingaphantsi kwexabiso elichaziweyo, akukho mpahla okanye ikhefu kufuneka livele kuyo nayiphi na inxenye yepateni. Ngexesha lenkqubo yokufihlakeleyo, akufuneki ukuba kubekho ulwakhiwo olungekho mgangathweni, i-welds ayisebenzi, kulibaziseka, isinyithi, okanye isinyithi.
4. Akukho nto iphambi kokuvavanywa, ukuba amalungiselelo emodeli afunyenwe ukuba anesiphene okanye kukungabikho kwezixhobo ezingafanelekanga, isampulu inokutsalwa kwaye itshintshwe isampulu eyenziwe kwityhubhu enye.
5. Ukuba nayiphi na isampulu emele ityhubhu ayihambelani neemfuno ezichaziweyo, umenzi unokuthatha isampulu kwisiphelo esinye setyhubhu yovavanyo ongezelelweyo de kufezekiswe iimfuno. Nangona kunjalo, ubude bombhobho ogqityiweyo emva kokuba isampulu akufuneki bube ngaphantsi kwe-80% yobude bokuqala. Ukuba kukho isampulu yetyhubhu emele i-batch yeemveliso azihambelani neemfuno ezichaziweyo, umenzi unokuthatha iityhubhu ezimbini ezongezelelweyo kwi-batch yeemveliso kwaye usike iisampulu zokuvavanywa ngokutsha. Ukuba iziphumo zala maxesha onke zihlangabezane neemfuno, i-batch ye-tubes ifanelekile ngaphandle kwetyhubhu yangaphambili ekhethwe njengesampulu. Ukuba kukho iisampulu eziphindaphindiweyo azifezekisi iimfuno ezichaziweyo, umenzi unokusampula iityhubhu ezisele ze-batch nganye nganye. Ekukhetheni komenzi, nayiphi na i-bhabhu ye-tubs inokuba shushu kwakhona iphinde inyangwe kwaye iphinde ihlawulwe njengebhendi entsha yeetyhubhu.
Uvavanyo lwempembelelo:
1. Kuba iityhubhu, iseti yeesampulu ziya kuthathwa kwitothi nganye (ngaphandle kokuba iinkqubo ezibhaliweyo zibonakalisiwe ukuba zifezekise iimfuno zomthetho). Ukuba i-odolo ilungisiwe kwi-A10 (SR16), uvavanyo lunyanzelekile.
2. Ukukhuphela imibhobho yensimbi emi-3 kufuneka ithathwe kwibhendi nganye yovavanyo. Iityhubhu zovavanyo ziya kukhethwa ngokungacwangciswanga, kwaye indlela yesampulu iya kuqinisekisa ukuba iisampulu zinikezelwe zibonisa ukuqala komjikelo wokuphela kobushushu kunye neziphelo zangaphambili nangasemva kwe-Deadves ngexesha lonyango lobushushu.

4. Akukho nto iphambi kokuvavanywa, ukuba amalungiselelo emodeli afunyenwe ukuba anesiphene okanye kukungabikho kwezixhobo ezingafanelekanga, isampulu inokutsalwa kwaye itshintshwe isampulu eyenziwe kwityhubhu enye. Imizekelo ayifanelanga ukuba igwetywe ngokulula ngenxa nje yokuba ayifezekisi iimfuno zamandla afunyenwe.
5. Ukuba isiphumo sesampulu engaphezulu kwesinye iphantsi kunemfuno esezantsi yamandla, okanye isiphumo sesampulu enye iphantsi kwe-2/3 yemfuno eqingqiweyo ye-2/3 yesampulu emithathu ebonakalayo, ephindaphindiweyo iya kuthathwa kwiqhekeza elifanayo kwaye iphinde ithathelwe ingqalelo. Impembelelo amandla e-task nganye ephilisiweyo iya kuba nkulu kune okanye ilingane nemfuno eqingqiweyo ebonakalayo.
6. Ukuba iziphumo zovavanyo oluthile azifikeleli kwiimfuno kunye neemeko zovavanyo olutsha azifezekiswanga, emva koko zithathwe iisampulu ezintathu ezongezelelweyo kwinye yeziqwengana ezintathu zebhetshi. Ukuba zonke iimeko ezongeziweyo ziyahlangabezana neemfuno, i-batch ifanelekile ngaphandle kwento engaphumelelanga. Ukuba ngaphezulu kwesinye isiqwengana sobunye esongeziweyo asifikeleli kwiimfuno, umvelisi unokukhetha ukuhlola iziqwenga ze-batch nganye nganye, okanye i-batch kwaye ihlole kwibhetshi entsha.
7. Ukuba ngaphezulu kwesinye sezinto ezintathu zokuqala ezifunekayo ukubonisa i-batch yeziqinisekiso ziyaliwe, ukuhlolwa kwakhona akuvunyelwanga ukubonisa ibhendi yeetyhubhu. Umvelisi unokukhetha ukuhlola amabetya ashiyekileyo ngeqhekeza, okanye ahlaziye i-batch kwaye ahlole kwi-batch entsha.
Uvavanyo lwe-hydrostatic:
I-1. Umbhobho ngamnye uya kufakwa kuvavanyo loxinzelelo lwe-hydrostatic yombhobho kuphela emva kokuthamba (ukuba kufanelekile) kunye nonyango lobushushu (ukuba kufanelekile), kwaye luya kufika uxinzelelo lwe-hydrostatic ochaziweyo ngaphandle kokuvuza. Ingcinezelo yovavanyo yokubamba ixesha lenziwa ngaphantsi kwe-5s. Kwimibhobho ye-weldar, ii-wels zemibhobho ziya kutshekishwa ukuba zivuzwe phantsi koxinzelelo lovavanyo. Ngaphandle kokuba lonke uvavanyo lwe-Pipe lwenziwe ubuncinci kwangethuba kuxinzelelo olufunekayo kwimeko yokugqibela yombhobho ofunekayo, umzi-mveliso wokungenela intambo kufuneka enze uvavanyo lwe-hydrostatic (okanye alungiselele lo mbhobho) kuwo wonke umbhobho.
I-2. Imibhobho ekubeni iphikwe bubushushu iya kufakwa kuvavanyo lwe-hydrostatic emva konyango lokugqibela lobushushu. Uxinzelelo lovavanyo lwayo yonke imibhobho eneziphelo ezinesithukuthezi ziya kuba okungenani uxinzelelo lovavanyo lwentambo kunye nokudibanisa.
3 .aterterters Ukulungiswa kwe-pipe yombhobho egqityiweyo kunye nakuphi na ukudibanisa ubushushu, uvavanyo lwe-hydrostatic luya kwenziwa emva kwesiphelo okanye umsonto.
