Amashubhu ayisikwele enziwe ngokwezifiso anezici ezahlukahlukene
1. Ukuchezuka okuvumelekile kobukhulu bodonga lwepayipi eliyisikwele akumele kudlule ukuhlanganisa noma ukususa u-10% wogqinsi oluvamile lodonga lapho ukushuba kodonga lungengaphezu kuka-10mm, futhi kuhlanganiswe noma kukhishwe u-8% wogqinsi lodonga lapho ukujiya kodonga bukhulu kuno-10mm. 10mm, ngaphandle kokuqina kodonga lwekhona nendawo yokushisela.
2.Ubude obujwayelekile bokulethwa kwepayipi eliyisikwele elingunxande ngu-4000mm-12000mm, ikakhulukazi u-6000mm no-12000mm. Ishubhu elingunxande livunyelwe ukuletha imikhiqizo yobude obufushane nengagxilile engekho ngaphansi kuka-2000mm, noma ngesimo seshubhu yesixhumi esibonakalayo, kodwa i-Demander izosika ishubhu yesixhumi esibonakalayo lapho ilisebenzisa. Isisindo sobude obufushane kanye nemikhiqizo yobude obunganqunyelwe akufanele seqe u-5% wevolumu yokulethwa okuphelele, futhi kumashubhu esikhashana esikwele anesisindo sethiyori esikhulu kuno-20kg / m, akumele seqe u-10% wevolumu yokulethwa okuphelele.
3. Idigri yokugoba yepayipi elingunxande eliyisikwele akufanele libe likhulu kuno-2mm imitha, futhi ingqikithi yokugoba idigri akufanele ibe nkulu kuno-0.2% wobude obuphelele.
Izinkambu zokufaka isicelo ze-square tube: isetshenziswa kabanzi embonini yemishini, embonini yezokwakha, embonini yensimbi, izimoto zezolimo, izindawo zokugcina izithombo zezolimo, imboni yezimoto, ujantshi wesitimela, onogada bomgwaqo omkhulu, uhlaka lwamathambo, ifenisha, umhlobiso kanye nesakhiwo sensimbi.
Ezokwakha ubunjiniyela, udonga lwamakhethini engilazi, umhlobiso wesicabha nefasitela, isakhiwo sensimbi, i- guardrail, ukukhiqizwa kwemishini, ukukhiqizwa kwezimoto, ukukhiqizwa kwemishini yasendlini, ukwakhiwa kwemikhumbi, ukukhiqizwa kweziqukathi, amandla kagesi, ukwakhiwa kwezolimo, indawo yokushisa yezolimo, uhlaka lwebhayisikili, uhlaka lwesithuthuthu, ishalofu, imishini yokufaneleka, izinto zokungcebeleka nezokuvakasha, ifenisha yensimbi, imininingwane ehlukahlukene yebhokisi likawoyela, ipayipi likawoyela kanye nepayipi lepayipi, amanzi, igesi, indle Air, ukufudumeza nokunye ukuthuthwa kwamanzi, ukulwa nomlilo nokusekela, imboni yezokwakha, njll.
