Amapayipi e-carbon steel Sheduli angu-40 ahlukaniswa ngokusekelwe kwinhlanganisela yezinto ezihlanganisa isilinganiso sobukhulu be-diameter-to-wall, amandla wezinto ezibonakalayo, ububanzi bangaphandle, ukushuba kodonga, namandla okucindezela.
Ukuqokwa kweshejuli, njengoHlelo 40, kubonisa inhlanganisela ethile yalezi zici. Kumapayipi Eshejuli angu-40, ngokuvamile afaka ukujiya kodonga olumaphakathi, okushaya ibhalansi phakathi kwamandla nesisindo. Isisindo sepayipi singahluka ngokusekelwe ezicini ezifana nebanga elithile le-carbon steel esetshenzisiwe, ububanzi, nokuqina kodonga.
Ukwengeza ikhabhoni ensimbi kungathinta isisindo, ngokuqukethwe kwekhabhoni ephezulu ngokuvamile okuholela kumapayipi alula. Nokho, kokubili ukushuba kodonga nobubanzi nakho kudlala indima ebalulekile ekunqumeni isisindo.
Isheduli 40 ibhekwa njengesigaba sokucindezela okuphakathi, esifanele izinhlelo zokusebenza ezihlukahlukene lapho kudingeka khona izilinganiso zokucindezela okumaphakathi. Uma udinga ulwazi oluthe xaxa noma usizo mayelana neSheduli 40 yamapayipi ensimbi ye-carbon, zizwe ukhululekile ukusithinta ukuze uthole olunye usizo.

Isheduli 40 ipayipi lensimbi ye-carbon iwusayizi wepayipi ojwayelekile osetshenziswa embonini yezokwakha. Kubhekiselwa ebukhulu bodonga lwamapayipi futhi kuyingxenye yohlelo olujwayelekile olusetshenziselwa ukuhlukanisa amapayipi ngokusekelwe ekugqineni kodonga kanye namandla okucindezela.
Kuhlelo lweSheduli 40:
- "Ishejuli" isho ukushuba kodonga lwepayipi.
- "I-Carbon steel" ikhombisa ukwakheka kwepayipi, okuyi-carbon ne-iron ngokuyinhloko.
Amapayipi e-carbon steel Sheduli 40 avame ukusetshenziselwa izinhlelo zokusebenza ezihlukahlukene, kuhlanganise nokuthuthwa kwamanzi negesi, ukusekelwa kwesakhiwo, kanye nezinjongo ezijwayelekile zezimboni. Baziwa ngamandla abo, ukuqina, nokuguquguquka, okubenza babe ukukhetha okudumile kumaphrojekthi amaningi wokwakha nobunjiniyela.
Ukubunjwa Kwekhemikhali kweSheduli 40 Ipayipi Lensimbi Yekhabhoni
Isheduli 40 izoba nogqinsi oluthile olunqunywe kusengaphambili, kungakhathaliseki ukuthi yiliphi ibanga elithile noma ukwakheka kwensimbi esetshenzisiwe.
