Ukucaciswa kwepayipi lensimbi yensimbi enobubanzi obukhulu kuchazwa ngobubanzi obungaphandle, ukushuba kodonga, ubude, kanye nebanga lezinto ezibonakalayo. Amadayamitha angaphandle ngokuvamile asukela ku-200 mm kuya ku-3000 mm. Amasayizi amakhulu kangaka abenza bakwazi ukuthutha ukugeleza kwamanzi amakhulu futhi banikeze ukusekelwa kwesakhiwo, okubalulekile kumaphrojekthi amakhulu.

Ipayipi lensimbi eligoqiwe elishisayo ligqama ngezinzuzo zalo zenqubo yokukhiqiza: ukugoqa okunezinga lokushisa eliphezulu kuguqula amabhilidi ensimbi abe amapayipi anogqinsi olufana nodonga kanye nesakhiwo sangaphakathi esiminyene. Ukubekezelela ububanzi bayo bangaphandle kungalawuleka phakathi kuka-±0.5%, okuyenza ifanelekele amaphrojekthi anezidingo eziqinile zobukhulu, njengamapayipi esitimu ezitshalweni ezinkulu zamandla ashisayo kanye namanethiwekhi okushisisa amaphakathi nedolobha.

Q235 carbon steel pipefuthiA36 carbon steel pipebabe nemingcele ecacile ecacile yamabanga ahlukene wezinto ezibonakalayo.

1.Q235 ipayipi lensimbi: Ipayipi lensimbi le-Q235 liyipayipi elivamile le-carbon structural steel e-China. Ngamandla okukhiqiza angu-235 MPa, ivamise ukukhiqizwa ngogqinsi lwezindonga oluyi-8-20 mm futhi isetshenziselwa ikakhulukazi izicelo zokuthutha uketshezi olunomfutho ophansi, njengokuphakelwa kwamanzi kamasipala nokukhipha amanzi, kanye namapayipi ajwayelekile egesi yezimboni.

2.A36 carbon steel pipe: I-A36 carbon steel pipe iyibanga lensimbi elijwayelekile emakethe yamazwe ngamazwe. Inamandla okukhiqiza aphakeme kancane (250MPa) kanye ne-ductility engcono. Inguqulo yayo yobubanzi obukhulu (ngokuvamile enobubanzi obungaphandle obungu-500mm noma ngaphezulu) isetshenziswa kakhulu ekuqoqeni uwoyela negesi namapayipi okuthutha, adinga ukumelana nokucindezela okuthile nokuguquguquka kwezinga lokushisa.
