IShedyuli ye-40 ye-carbon steel pipes ihlelwe ngokusekelwe kwindibaniselwano yezinto ezibandakanya umlinganiselo we-diameter-to-wall thickness, amandla ezinto eziphathekayo, i-diameter yangaphandle, ubukhulu bodonga, kunye nomthamo woxinzelelo.
Ukutyunjwa kweshedyuli, njengeShedyuli 40, kubonisa indibaniselwano ethile yale miba. Kwimibhobho yeShedyuli ye-40, ngokuqhelekileyo ibonisa ubukhulu bodonga oluphakathi, ukubetha ibhalansi phakathi kwamandla kunye nobunzima. Ubunzima bombhobho bunokwahluka ngokusekelwe kwizinto ezifana nebakala elithile le-carbon steel esetyenzisiweyo, ububanzi kunye nobukhulu bodonga.
Ukongeza ikhabhoni kwintsimbi kunokuchaphazela ubunzima, kunye nomxholo ophezulu wekhabhoni obangelwa ngokubanzi kwimibhobho elula. Nangona kunjalo, zombini ubukhulu bodonga kunye nobubanzi budlala indima ebalulekileyo ekunqumeni ubunzima.
IShedyuli ye-40 ithathwa njengeklasi yoxinzelelo oluphakathi, olufanelekileyo kwizicelo ezahlukeneyo apho ukulinganiswa koxinzelelo oluphakathi kuyadingeka. Ukuba ufuna ulwazi oluthe vetshe okanye uncedo malunga neShedyuli ye-40 yebhobho yentsimbi ye-carbon, zive ukhululekile ukuqhagamshelana nathi ukuze ufumane uncedo olungakumbi.

IShedyuli ye-40 ye-carbon steel pipe yimbhobho yomgangatho wokutyunjwa kobungakanani obusetyenziswa kwishishini lokwakha. Ibhekisela kubukhulu bodonga lombhobho kwaye inxalenye yenkqubo esemgangathweni esetyenziselwa ukwahlula imibhobho ngokusekelwe kubukhulu bodonga kunye nomthamo woxinzelelo.
Kwinkqubo yeShedyuli 40:
- "Ishedyuli" ibhekiselele kubukhulu bodonga lombhobho.
- "Intsimbi yeCarbon" ibonisa ukubunjwa kwezinto zombhobho, eyona nto i-carbon kunye nentsimbi.
IShedyuli ye-40 ye-carbon steel pipes isetyenziswa ngokuqhelekileyo kwizicelo ezahlukeneyo, kubandakanywa nokuthuthwa kwamanzi kunye negesi, ukuxhaswa kwesakhiwo, kunye neenjongo zoshishino jikelele. Baziwa ngokwamandla abo, ukuqina, kunye nokuguquguquka, okubenza babe lukhetho oludumileyo kwiiprojekthi ezininzi zokwakha nezobunjineli.
Ukubunjwa kweMichiza yeShedyuli ye-40 yeCarbon Steel Pipe
IShedyuli ye-40 iya kuba nobukhulu obuchanekileyo obunqunywe kwangaphambili, kungakhathaliseki ukuba ibakala elithile okanye ukubunjwa kwentsimbi esetyenzisiweyo.
