Isheduli 80 yepayipi lensimbi yensimbi iwuhlobo lwepayipi elibonakala ngodonga lwalo olujiyile uma liqhathaniswa namanye amashejuli, njengeSheduli 40. "Ishejuli" yepayipi isho ukushuba kodonga lwalo, okuthinta isilinganiso salo sokucindezela namandla esakhiwo.
Izimpawu Ezisemqoka Zeshejuli 80 Ipayipi Lensimbi Yekhabhoni
1. Ukuqina Kwezindonga: Kujiyile kunoHlelo 40, okunikeza amandla amakhulu nokuqina.
2. Isilinganiso Sokucindezela: Isilinganiso sokucindezela okuphezulu ngenxa yokuqina kodonga, okulwenza lufaneleke izinhlelo zokusebenza ezinomfutho ophezulu.
3. Impahla: Yenziwe nge-carbon steel, enikeza amandla amahle nokuqina, kanye nokumelana nokuguga.
4. Izicelo:
I-Industrial Piping: Isetshenziswa ezimbonini ezifana nowoyela negesi, ukucubungula amakhemikhali, kanye nokukhiqiza amandla.
Amapayipi: Afanele izintambo zokuphakela amanzi ezinomfutho ophezulu.
Ukwakhiwa: Kusetshenziswa ezinhlelweni zokusebenza lapho kudingeka amandla aphezulu.

Osayizi: Batholakala kububanzi bosayizi wamapayipi okuzisholo (NPS), ngokuvamile ukusuka ku-1/8 intshi ukuya ku-24 amayintshi.
Amazinga: Ivumelana namazinga ahlukahlukene afana ne-ASTM A53, A106, ne-API 5L, acacisa izidingo zezinto zokwakha, ubukhulu, nokusebenza.
Ukubunjwa Kwekhemikhali Kweshejuli 80 Ipayipi Lensimbi Yekhabhoni
IShedyuli 80 izoba nogqinsi oluthile olunqunywe kusengaphambili, kungakhathaliseki ukuthi yiliphi ibanga elithile noma ukwakheka kwensimbi esetshenzisiwe.

Hlela 80 Carbon Steel Pipe
Izinzuzo:
Amandla Aphezulu: Izindonga eziwugqinsi zinikeza ubuqotho besakhiwo obuthuthukisiwe.
Ukuqina: Ukuqina kwe-Carbon steel kanye nokumelana nokugqoka kwenza lawa mapayipi ahlale isikhathi eside.
I-Versatility: Ifanele uhla olubanzi lwezinhlelo zokusebenza nezimboni.
Ububi:
Isisindo: Izindonga eziwugqinsi zenza amapayipi asinde futhi kube yinselele enkulu ukuwaphatha nokuwafaka.
Izindleko: Ngokuvamile zibiza kakhulu kunamapayipi anezindonga ezincanyana ngenxa yokwanda kokusetshenziswa kwempahla.
