I-A252 Ibanga 3 Ipayipi lensimbi yemigqa yendle
Emhlabeni wokuklanywa kobunjiniyela nokwakha, ukuba namapayipi ensimbi athembekile futhi ahlukahlukene acacile. I-A252 I-Grade 3 I-Pipe yensimbi ifanela le ncazelo ngokuphelele, okwenza kube ngenye yezinhlobo zensimbi ezisetshenziswa kakhulu kuyo yonke imboni. Ngamandla ayo aphakeme kanye nokuphikiswa kokugqwala, le pipayi yensimbi iletha inguquko engakaze ibonwe ukuze ithuthukise ukwakhiwa kwamapayipi.
I-A252 Ibanga 3 Ipayipi lensimbiyaziwa ngamandla ayo aphezulu aphezulu, edlula ezinye izinhlobo zepayipi lensimbi. Inokumelana okukhulu nokucindezelwa, ukuqinisekisa ukuqina okuhlelekile kwesakhiwo. Le mfanelo iba lubaluleke kakhulu lapho imigqa yendle ifakwa ngaphansi kwemithamo emikhulu yokuqinisekisa ukusebenza okuthembekile nokuhlala isikhathi eside. Ochwepheshe ensimini ye-Engineering bangakwethemba lepayipi lensimbi ukubekezelela izimo ezinzima.
Enye into ehlukile ye-A252 Banga 3 Ipayipi lensimbi yokwelashwa kwayo okungaphezulu. Ukuqinisekisa ikhwalithi ephezulu, amapayipi aphathwa ngokucophelela ukuvikela i-oxidation kanye nokugqwala. Lokhu kusho ukuthi ipayipi lingasebenza ezindaweni ezonaka kakhulu ezinjenge-Oceans, ixhaxha kanye nezitshalo zamakhemikhali ngaphandle kokuyekethisa ukusebenza kwayo. Ukuqina kwepayipi indawo yepayipi kwenza kube ukukhetha okuhle kwamaphrojekthi adinga ukumelana nokuqina okuphezulu.

Ukuguquguquka okuhlukahlukene kwe-A252 I-Grade 3 Steel Pipe kufakazelwa ngohlobo lwayo olubanzi lwezicelo. Ngaphezu komthelela wayo ekwakheni indle, ingasetshenziswa ezimbonini ezahlukahlukene kufaka phakathi uwoyela negesi, ukwelashwa kwamanzi kanye namaphrojekthi wengqalasizinda. Lokhu kuguqulwa kwenza kube ukukhetha kokuqala konjiniyela kanye nosonkontileka abafuna izixazululo zensimbi ezithembekile nezisebenzayo zamaphrojekthi abo.
Uma kukhulunywaumthungiulayiniUkwakha, amapayipi ensimbi ama-A252 amabanga ama-3 agqamile. Amandla ayo aphakeme kanye nokumelana nokugqwala akubeka ngaphandle kwamanye amapayipi ensimbi emakethe. Ngokukhetha lolu hlobo lwepayipi, onjiniyela bangaqiniseka ukuthi iphrojekthi yabo izokwenza isivivinyo sesikhathi, iqinisekisa ukuqina kanye nokusimama kwayo.
Ngamafuphi, i-A252 Ibanga 3 I-Pipe yensimbi ngumdlalo wegeyimu ekwakhiweni kwamapayipi wendle ngokwakha kwawo okufakwayo kwangaphansi kwe-arc. Amandla awo akhethekile okuqina nokumelana nokugqwala kwenza kube yisinqumo esihle sonjiniyela abafuna izixazululo ezithembekile, eziguquguqukayo zensimbi. Noma ngabe ukuqina kwesakhiwo noma isidingo sokumelana nezimo ezilonakalisayo, leli moto yensimbi lidlula okulindelwe. Amukele ipayipi lensimbi ye-A252 yeBanga le-3 futhi uhlangabezana nekhwalithi engenakuqhathaniswa eletha emsebenzini wakho wobunjiniyela.
