Izidingo ezijwayelekile zobuchwepheshe zensimbi engagqwali
I-GB / T19228-2011 isuselwa ku-GB / T12771-2008, ngakho-ke izidingo ezilandelayo zobuchwepheshe ziyasebenza nakwenye ithubhu yensimbi engenasisekelo ejwayelekile.
Ⅰ. Usayizi nokubekezelelana
Ukuzungeza: ububanzi obungaphandle bokuphambuka okuvumelekile C kungu-± 0.5% D, DN150-300, 0.75% D ngezansi kwe-DN150;
Ubukhulu: Ukuphambuka okuvumelekile: ± 10% S;
Ubude: 3000-9000mm, nayo ingenziwa ngezifiso njengoba kudingeka, ukuphambuka okuvumelekile: 0 ~ +20 mm;
Ukugoba Degree: 2mm / M;
I-Slope: Umthambeka wembobo yensimbi yensimbi kufanele uhlangabezane nezidingo etafuleni elilandelayo.
Ⅱ. Indlela Yokubala Isisindo
Ishubhu yensimbi engagqwali ivame ukulethwa ngokwesisindo semfundiso, futhi ingalethwa ngokuya ngesisindo sangempela ngemuva kokuxoxisana. Lapho zilethwa ngokwesisindo sethiyori, isisindo senkolelo sibalwa ngokuya ngefomula (I)

Insimbi Engagqwali Iphethini Tube
- Ishubhu ngokuyinhloko lishiselwe ishubhu noma iphethini ithubhu, evame ukusetshenziswa njengezandla zokubopha noma ukuhlobisa, okokusebenza kwayo ngokuvamile kungu-304 insimbi engenasici noma okungcono. Inqubo yalo yokukhiqiza yileyokuqala ithubhu yokucindezela ipayipi ngensimbi yensimbi, bese kuthi ukufakwa kwe-welding jikelele, futhi ekugcineni kukhethwe futhi kupholishwe.
- Ngokuvamile kuyiphethini yedayimane noma iphethini eyindilinga, isebenzisa i-steel strip embossing nensimbi yensimbi eyenza i-welding.
Ububanzi bayo ngokuvamile bungu-22mm-48mm, ukusetshenziswa okuyinhloko: umhlobiso wasekhaya, izitebhisi zokubiyela izitebhisi, izibambo zepayipi, izibambo zemoto, njll.

Engagqwali Handrail Tube, Wall Handrail Tube, Handrail Tube for the Handicapped
Lo mkhiqizo unesakhiwo senoveli nobuchwepheshe obuholayo. Ngokuya ngezici ze-handrail, inhlanganisela ephilayo yokusakaza nepayipi iqinisekisa ukuthi i-handrail inamandla amakhulu nolayini obushelelezi bendawo. Inqubo ye-handrail splicing ixazulula inkinga yokuthi amanye amakhona ngemuva kwe-handrail welding awakwazi ukwelashwa ngaphezulu. Ngokuya ngezidingo zobuchwepheshe, ubuso be-handrail bungelashwa nge-brush, isihlabathi blasting, knurling, spray spray, kanye ne-spray molding. Ngemuva kwalokho, indawo iphathwa ngenqubo ekhethekile yokulwa nokungcola, iyenze ibukeke kahle, ingenawo uwoyela futhi ihlanzeke kalula. Inqubo ekhethekile yokushisela yokwenza i-handrail ibhekwe nxazonke kusuka kuzici zokusebenza, imishini, kanye nemingcele yenqubo ukuqinisekisa ikhwalithi yokushisela.
