Inqubo Yokukhiqiza Ipayipi Le-SMLS engenamthungo
Ukukhetha Okungahluziwe:I-carbon steel yekhwalithi ephezulu ikhethwa njengento eluhlaza yamapayipi ensimbi angenamthungo. Okuqukethwe kwekhabhoni ensimbi kuyisici esibalulekile ekunqumeni izakhiwo zayo kanye nokufaneleka kwezicelo ezihlukahlukene.
Ukushisisa nokubhoboza:Impahla eluhlaza ishiselwa ezingeni lokushisa eliphezulu bese ibhobozwa ukwenza igobolondo elingenalutho. Le nqubo ibalulekile ekudaleni umumo wokuqala wepayipi futhi ngokuvamile ifinyelelwa ngezindlela ezinjengokubhoboza ngokuzungezayo, ukukhipha, noma amanye amasu akhethekile.
Ukugoqa kanye nosayizi:Igobolondo elibhoboziwe lingena ezinqubweni zokugingqika kanye nokulinganisa ukuze kuncishiswe ububanzi balo nobukhulu bodonga libe izilinganiso ezidingekayo. Lokhu ngokuvamile kufinyelelwa kusetshenziswa uchungechunge lwezigayo ezigoqayo nezigayo zokulinganisa ukuze kuzuzwe umumo nobukhulu obufunekayo.
Ukwelashwa Kokushisa:Ipayipi lensimbi le-carbon steel elingenamthungo lingaphansi kwezinqubo zokwelashwa kokushisa okufana nokucwiliswa, ukujwayela, noma ukucisha kanye nokushisa ukuze kuthuthukiswe izici zayo zomshini futhi kususe noma yikuphi ukucindezelwa okusalayo. Ukwelashwa kokushisa nakho kusiza ekuzuzeni i-microstructure oyifunayo kanye nezakhiwo ze-carbon steel.
Ukuhlola Nokuhlola:Kuyo yonke inqubo yokukhiqiza, ipayipi lekhabhoni elingenamthungo libhekana nezindlela zokuhlola ezihlukahlukene ezingabhubhisi nezilimazayo ukuze kuqinisekiswe ukuthi lihlangabezana nezindinganiso zekhwalithi ezidingekayo. Lokhu kungase kuhlanganise ukuhlolwa kwe-ultrasonic, ukuhlolwa kwe-hydrostatic, ukuhlolwa kwamanje kwe-eddy, nokuhlola okubukwayo.
Ukuqeda kanye nokuhlanganisa:Uma ipayipi elingenamthungo lifinyelela izicaciso ezidingekayo, lingena ezinqubweni zokuqeda ezifana nokuqondisa, ukusika, nokuqeda ukuqeda. Ukwengeza, ipayipi lingase limbozwe ngezinto zokuvikela ezifana ne-varnish, upende, noma i-galvanizing ukuze kuthuthukiswe ukumelana nokugqwala, ikakhulukazi esimweni se-carbon steel.
Ukuhlolwa Kokugcina Nokupakishwa:Ipayipi lensimbi engenamthungo eliqediwe lihlolwa okokugcina ukuze kuqinisekiswe ukuthi lihlangabezana nazo zonke izindinganiso zekhwalithi kanye nezidingo zamakhasimende. Bese ipakishwa ngokucophelela futhi ilungiselelwe ukuthunyelwa ekhasimendeni.

Ukuhlolwa kwe-Hydrostatic
ipayipi elingenamthungo lizomelana nokuhlolwa kwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld noma umzimba wepayipi.
