Chitoliro chathu chopangidwa ndi chitsulo chosungunuka chimapangidwa ndi zida zapamwamba kwambiri kudzera pakuponyera ndi kulondola kwa makina otulutsa.Kuyang'aniridwa mosamala popanga zida zonse zoyezera, odulira ndi zida zina zopangira zitoliro zathu zimatsimikiziridwa kuti zikhale zolimba, ngakhale kuwala kwapamtunda, kukula kwa geometrical mwatsatanetsatane kukula ndi kukana kwa dzimbiri, kutsimikizika kolondola komanso kosavuta pakuyika ndi kusinthana.

Zakuthupi:
1. makina katundu:
Mphamvu yolimba> = 33kg/square mm
Elongation > = 8%
Kuuma
2. hydraulic test:
Kuthamanga kwa mayeso: 25kg / square cm (= 335lbs / sikweya mu)
Kuthamanga kwa ntchito: 16kg / lalikulu masentimita (227lbs / sikweya mu)
Pakali pano zovekera zathu zachitsulo zosungunuka zimapangidwira ku Britain ndi America etc.Zomwe zimapezeka nthawi zonse ndi zinthu zotsatirazi: Elbow, tee, mtanda.Soketi, mgwirizano, bushing, backnut, flange, nipple, etc. Zogulitsa zimasiyana kuchokera ku 1/4 inchi mpaka 6 inchi.Amagawidwa makamaka kukhala omveka kapena mikanda.
Kupatula apo, kuyitanitsa zina zomwe sizinatchulidwe zitha kukambidwanso.Mapaipi athu ndi oyenera kujowina mizere ya mapaipi a nthunzi, gasi, mafuta, mpweya ndipo amagwiritsidwanso ntchito ngati zida zomangira mipanda ndi njanji.
