Iimfuno ngokubanzi zobugcisa ityhubhu insimbi
I-GB / T19228-2011 isekwe kwi-GB / T12771-2008, ke ezi mfuno zilandelayo zobuchwephesha ziyasebenza nakwenye ityhubhu yentsimbi engenasiphelo.
Ⅰ. Ubukhulu kunye nokunyamezelana
Ujikelezo: ubukhulu obungaphandle obunxaxhileyo obuvumelekileyo C ngu- ± 0.5% D, DN150-300, 0.75% D ngezantsi kwe-DN150;
Ubukhulu: Ukuphambuka okuvumelekileyo: ± 10% S;
Ubude: 3000-9000mm, ikwanokwenziwa njengemfuneko, ukuphambuka okuvumelekileyo: 0 ~ +20 mm;
Ukuguqa: 2mm / M;
Ithambeka: Ithambeka lezibuko lesinyithi kufuneka lihlangabezane neemfuno kule theyibhile ilandelayo.
Ⅱ. Indlela yokubala yobunzima
Ityhubhu yentsimbi engenasici ihanjiswa ngokubanzi ngokobunzima bethiyori, kwaye inokuhanjiswa ngokobunzima boqobo emva kothethathethwano. Xa kuhanjiswa ngokobunzima bethiyori, ubunzima bethiyori bubalwa ngokomgaqo (I)

Phawula:
W-ubunzima bethiyori yetyhubhu yentsimbi ngokweekhilogram kwimitha nganye (kg / m);
3.1 = 3.1416;
S - ubukhulu bendonga yokulinganisa ityhubhu yentsimbi, kwiimilimitha (mm);
D -Ububanzi obuqingqiweyo obungaphandle betyhubhu yentsimbi, kwiimilimitha (mm):
P - Ukuxinana kwentsimbi engenasici kwi kg / dm3, nceda ujonge le theyibhile ilandelayo ngobuninzi bebakala ngalinye.

- Umbhobho ubukhulu becala nge welding ityhubhu okanye ipateni ityhubhu, esetyenziswa ngokubanzi njengezibambo zokubamba okanye umhombiso, izinto zawo ngokubanzi zingama-304 zentsimbi okanye zingcono. Inkqubo yayo yemveliso kukuba ityhubhu yokuqala ngokucinezela ityhubhu ngomtya wentsimbi, emva koko ukubumba ukuwelda ngokubanzi, kwaye ekugqibeleni ukukha kunye nokucoca.
- Yimodeli yedayimani ngokubanzi okanye isetyhula, yamkela i-strip ye-steel embossing kunye ne-coil yensimbi eyenza i-welding.
Ububanzi bayo ngokubanzi yi-22mm-48mm, isicelo esingundoqo: umhombiso wasekhaya, izinyuko ezibambisayo zokubamba, izibambo zombhobho, izinto zokubamba imoto, njl.

Stainless Handrail Tube, Wall Handrail Tube, Handrail Tube kubantu abakhubazekileyo
Le mveliso inesakhiwo senoveli kunye netekhnoloji ekhokelayo. Ngokutsho iimpawu handrail, indibaniselwano organic bephosa kwaye umbhobho iqinisekisa ukuba handrail unamandla aphezulu kunye nemigca umphezulu egudileyo. Le nkqubo handrail usifake usombulula ingxaki yokuba ezinye iikona emva handrail welding ayikwazi ukunyangwa umphezulu. Ngokweemfuno zobugcisa, umphezulu we-handrail unokunyangwa ngebrashi, ukuqhushumba kwesanti, ukudibanisa, ukupeyinta ukutshiza, kunye nokubumba. Emva koko, umphezulu uphathwa ngendlela ekhethekileyo yokulwa ungcoliseko, uyenza ibonakale intle, ingenayo ioyile kwaye kulula ukuyicoca. Inkqubo ekhethekileyo ye-welding yokwenza i-handrail ibekwe esweni macala onke kwimiba yokusebenza, izixhobo, kunye nenkqubo yeparamitha yokuqinisekisa umgangatho we-welding.
