Ngaphezu kokuqinisekisa ukwakheka kwamakhemikhali kanye nezakhiwo zemishini, ukuhlolwa kwe-hydrostatic kwenziwa ngakunye, futhi kwenziwa ukuhlolwa kokushabalalisa nokwelula. Ngaphezu kwalokho, kunezidingo ezithile zesakhiwo esincane, usayizi wezinhlamvu, kanye nesendlalelo sokususa amakhabhoni epayipi lensimbi eliqediwe.
Ukuhlolwa Kokunamathela:
1. Ngezinto zensimbi zemikhiqizo, umenzi kufanele enze ukuhlolwa kokuthamba. Ngepayipi elihlanganisiwe likagesi, elisekelwe ekukhetheni komenzi, ukuhlolwa kokuthamba kungenziwa epuletini lensimbi elalivame ukwenza ipayipi noma eliqhutshwa ngqo epayipini lensimbi. Ukuhlolwa okwenziwe emkhiqizweni kungasetshenziswa futhi njengokuhlolwa komkhiqizo.
2. Amashubhu okuhlola kufanele akhethwe ngokungahleliwe. Uma kudingeka ukuhlolwa okuningi, indlela yokuthatha amasampula kufanele iqinisekise ukuthi amasampula athathiwe angamelela ukuqala nokuphela komjikelezo wokwelashwa kokushisa (uma kusebenza) kanye nemikhawulo yomibili yeshubhu. Uma kudingeka ukuhlolwa okuningi, iphethini kufanele ithathwe kumashubhu ahlukene ngaphandle kokuthi isampula yeshubhu ejiyile ingathathwa kuzo zombili izinhlangothi zeshubhu.
3. Isampula yepayipi engenamthungo ingathathwa kunoma iyiphi indawo kumjikelezo wepayipi; isampula yepayipi ehlanganisiwe kufanele ithathwe cishe ku-90 ° kuya kumthungo wokushisela, noma ngokukhetha komenzi. Amasampula athathwa cishe ingxenye yesine yobubanzi be-strip.
4. Kungakhathaliseki ukuthi ngaphambi nangemva kokuhlolwa, uma ukulungiswa kwesampula kutholakala kunephutha noma kukhona ukuntuleka kwezinto ezingafanele injongo yokuhlolwa, isampula ingasuswa bese ithathelwa indawo ngesinye isampula esenziwe ngepayipi elifanayo.
5. Uma ukuhlolwa kokucindezelwa okumelela iqoqo lemikhiqizo kungahlangabezani nezidingo, umenzi angathatha amanye amashubhu amathathu avela eqenjini elifanayo lamashubhu ukuze ahlolwe kabusha.
Uma konke ukuhlolwa kabusha kwamasampula kuhlangabezana nezidingo, inqwaba yamashubhu iyafaneleka ngaphandle kweshubhu elingafaneleki elathathwa isampula ekuqaleni.
Uma amasampula angaphezu kwelilodwa ethathwa ekuqaleni noma amasampula elilodwa noma ngaphezulu ukuze ahlolwe kabusha engahlangabezani nezidingo ezibekiwe, umenzi angahlola inqwaba yamashubhu ngalinye ngalinye.
Iqoqo lemikhiqizo elaliwe lingashiswa futhi licutshungulwe kabusha njengeqoqo elisha.
Ukuhlolwa Kokuthamba:
1. Isampula yokuhlola kufanele ibe yindandatho yokuhlola noma isiqeshana sokugcina esingaphansi kuka-63.5mm (2-1 / 2in).
2. Ama-specimens anganqunywa ngaphambi kokwelashwa ngokushisa, kodwa aphathwe ngokushisa okufanayo nepayipi elimelelwe. Uma kusetshenziswa ukuhlolwa kwe-batch, kuzothathwa izinyathelo zokuhlonza ubudlelwano phakathi kwesampula nepayipi lokuhlola. Isithando somlilo ngasinye ku-batch ngayinye kufanele sichotshozwe.
3. Isampula kumele ibekwe phakathi kwamapuleti amabili ahambisanayo. Kuqoqo ngalinye lamasampula okuhlola okusicaba, i-weld eyodwa yabekwa ku-90 ° kanti enye yabekwa ku-0 °. Isampula kumele ibekwe phansi kuze kube yilapho izindonga zamapayipi sezithintana. Ngaphambi kokuba ibanga phakathi kwamapuleti ahambisanayo lingaphansi kwenani elibekiwe, akukho mifantu noma ukuqhekeka okufanele kuvele kunoma iyiphi ingxenye yephethini. Phakathi nayo yonke inqubo yokusicaba, akufanele kube nesakhiwo esibi, ama-weld angahlanganiswanga, ukuhlukanisa, ukushiswa ngokweqile kwensimbi, noma ukukhishwa kwensimbi.
4. Kungakhathaliseki ukuthi ngaphambi nangemva kokuhlolwa, uma ukulungiswa kwesampula kutholakala kunephutha noma kukhona ukuntuleka kwezinto ezingafanele injongo yokuhlolwa, isampula ingasuswa bese ithathelwa indawo ngesinye isampula esenziwe ngepayipi elifanayo.
5. Uma noma yiliphi isampula elimele ithubhu lingahlangabezani nezidingo ezibekiwe, umenzi angathatha isampula kusukela ekugcineni okufanayo kwethubhu ukuze ahlolwe okwengeziwe kuze kube yilapho izidingo zihlangabezwa. Kodwa-ke, ubude bepayipi eliqediwe ngemva kokusampula akumele bube ngaphansi kuka-80% wobude bokuqala. Uma noma yiliphi isampula lethubhu elimele inqwaba yemikhiqizo lingahlangabezani nezidingo ezibekiwe, umenzi angathatha amashubhu amabili engeziwe eqoqweni lemikhiqizo futhi asike amasampula ukuze ahlolwe kabusha. Uma imiphumela yalokhu kuhlolwa kabusha konke ihlangabezana nezidingo, inqwaba yamashubhu iyafaneleka ngaphandle kwethubhu ekhethwe ekuqaleni njengesampula. Uma noma yiliphi lamasampula okuhlolwa kabusha lingahlangabezani nezidingo ezibekiwe, umenzi angathatha amashubhu asele eqoqweni ngalinye ngalinye. Ngokukhetha komenzi, noma yiliphi iqoqwana lamashubhu lingaphinde liphathwe ngokushisa futhi lihlolwe kabusha njengeqoqo elisha lamashubhu.
Ukuhlolwa Komthelela:
1. Kumapayipi, isethi yamasampula kufanele ithathwe kuhlu ngalunye (ngaphandle kokuthi izinqubo ezibhaliwe zibonisiwe ukuthi ziyahlangabezana nezimfuneko zomthetho). Uma i-oda lihleliwe ku-A10 (SR16), ukuhlolwa kuyimpoqo.
2. Ukuze kufakwe isivalo, kufanele kuthathwe amapayipi ensimbi amathathu ebhetshini ngalinye ukuze kwenziwe izivivinyo. Amapayipi okuhlola kufanele akhethwe ngokungahleliwe, futhi indlela yokuthatha amasampula kufanele iqinisekise ukuthi amasampula anikeziwe angamelela ukuqala nokuphela komjikelezo wokwelashwa kokushisa kanye nezingxenye zangaphambili nangemuva zesikhafu ngesikhathi sokwelashwa kokushisa.
3. Ukuhlolwa komthelela we-Charpy V-notch
4. Kungakhathaliseki ukuthi ngaphambi nangemva kokuhlolwa, uma ukulungiswa kwesampula kutholakala kunephutha noma kukhona ukuntuleka kwezinto ezingafanele injongo yokuhlolwa, isampula ingasuswa bese ithathelwa indawo ngesinye isampula esenziwe ngepayipi elifanayo. Amasampula akufanele abhekwe nje njengenephutha ngoba nje awahlangabezani nezidingo zamandla amancane adonswayo.
5. Uma umphumela wamasampula angaphezu kweyodwa ungaphansi kwesidingo samandla amancane aqunyiwe, noma umphumela wesampula eyodwa ungaphansi kuka-2/3 wesidingo samandla amancane aqunyiwe esibekiwe, amasampula amathathu engeziwe kufanele athathwe engxenyeni efanayo bese ehlolwa kabusha. Amandla omthelela wesampula ngayinye ehlolwe kabusha kufanele abe makhulu noma alingane nesidingo samandla amancane aqunyiwe esibekiwe.
6. Uma imiphumela yokuhlolwa okuthile ingahlangabezani nezidingo futhi izimo zokuhlolwa okusha zingahlangabezani, khona-ke amasampula amathathu engeziwe athathwa kuzo zonke ezinye izingcezu ezintathu zebhetshi. Uma zonke izimo ezengeziwe zihlangabezana nezidingo, ibhetshi liyafaneleka ngaphandle kwaleyo ehlulekile ekuqaleni. Uma izingcezu zokuhlola ezingaphezu kweyodwa zingahlangabezani nezidingo, umenzi angakhetha ukuhlola izingcezu ezisele zebhetshi ngayinye ngayinye, noma aphinde afudumale ibhetshi bese elihlola ngebhetshi entsha.
7. Uma izinto ezingaphezu kweyodwa kwezithathu zokuqala ezidingekayo ukufakazela inqwaba yezimfanelo zenqatshwa, ukuhlolwa kabusha akuvunyelwe ukufakazela ukuthi inqwaba yamashubhu iyafaneleka. Umenzi angakhetha ukuhlola amaqoqo asele kancane kancane, noma ukufudumala kabusha inqwaba bese eyihlola ngenqwaba entsha.
Ukuhlolwa kwe-Hydrostatic:
1. Ipayipi ngalinye kufanele lihlolwe ingcindezi ye-hydrostatic yepayipi lonke ngemva kokujiya (uma kufanele) kanye nokwelashwa kokugcina kokushisa (uma kufanele), futhi kufanele lifinyelele ingcindezi ye-hydrostatic ecacisiwe ngaphandle kokuvuza. Isikhathi sokuhlola sokubamba ingcindezi senziwe ngaphansi kwamasekhondi angu-5. Kumapayipi ahlanganisiwe, ukushintshwa kwamapayipi kufanele kuhlolwe ukuvuza ngaphansi kwengcindezi yokuhlola. Ngaphandle kokuthi ukuhlolwa kwepayipi lonke kwenziwe okungenani kusengaphambili ngengcindezi edingekayo esimweni sokugcina sepayipi, ifektri yokucubungula intambo kufanele yenze ukuhlolwa kwe-hydrostatic (noma ihlele ukuhlolwa okunjalo) kuyo yonke ipayipi.
2. Amapayipi okufanele aphathwe ngokushisa azohlolwa nge-hydrostatic ngemva kokwelashwa kokugcina kokushisa. Ingcindezi yokuhlola yawo wonke amapayipi aneziphetho ezinezintambo kufanele okungenani ibe yingcindezi yokuhlola yezintambo kanye nama-coupling.
3. Ngemva kokucubungula usayizi wepayipi eliyisicaba eliqediwe kanye nanoma yimaphi amalunga amafushane aphathwe ngokushisa, ukuhlolwa kwe-hydrostatic kufanele kwenziwe ngemuva kwesicaba noma intambo.
