Yintoni umahluko phakathi kwengqiniba edityanisiweyo kunye nengqiniba engenamthungo?

Ingqiniba edityanisiweyo yenziwe ngokugoba kombhobho kwaye inokudityaniswa, ngoko ibizwa ngokuba yingqiniba edityanisiweyo, oku akuthethi ukuba ine-welds. Enyanisweni, ngokuchaseneyo, i-elbow edibeneyo yenziwe ngokunyathela ngokuthe ngqo kombhobho kunye nokugoba. Ukuqwalasela uxinzelelo lwesakhiwo, umbhobho ongenamthungo usetyenziswa ngokubanzi. Endaweni yombhobho odityanisiweyo., Le nto ibizwa ngokuba yingqiniba engenamthungo kukuphosa kwaye ayinakudityaniswa.
Ingqiniba eWelded ayifani nengqiniba engenamthungo, kodwa ikwanengqiniba. Ukuveliswa kwe-elbow kwahlulwe kwi-welding, stamping, pushing and casting. Ingenamthungo ibhekisa kwingqiniba ngaphandle kwe-welding seam, hayi ingqiniba edityanisiweyo. Ingqiniba egxininisiweyo inomthungo othe tye wengqiniba kunye nengqiniba engenamthungo, emiselwa bubume bombhobho we-embryo.

I-elbow iyimveliso engenamthungo kwaye inokucutshungulwa ngokuthe ngqo kumbhobho ongenamthungo; I-elbows zizinto ezidibeneyo, ezenziwe nge-welding.

Umahluko phakathi kwengqiniba edityanisiweyo kunye nengqiniba engenamthungo kukuba ingqiniba ye-butt welded ine-weld ezimbini, ingqiniba edityanisiweyo ethe ngqo ineweld enye, kwaye ingqiniba engenamthungo ayinaweld.

1. Umahluko wembonakaloUmahluko phakathi komthungoingqinibakunye nengqiniba edibeneyo kukuba kukho i-weld. Ukongeza, ubukhulu bengqiniba engenamthungo abulingani xa buthelekiswa nobo bengqiniba edityanisiweyo.

2. Umahluko kwinkqubo yokubumbaInkqubo yokusebenzisa i-elbow engenamthungo iyafana naleyo ye-welding elbow. Nangona kunjalo, umahluko phakathi kwezi zibini kukuba ukuveliswa kwe-elbow kwahlulwe kwi-welding, stamping, pushing and casting. Ingqiniba engenamthungo yenziwe ngombhobho wentsimbi ongenamthungo, ngaphandle komthungo we-welding okanye i-elbow edibeneyo. I-elbow edibeneyo yenziwe ngepleyiti yensimbi eyenziwe ngokugoba kunye neenkqubo ezahlukeneyo ze-welding.

3. Ukusetyenziswa okwahlukeneyoIingqiniba ezingenamthungo zisetyenziswa ikakhulu njengemibhobho okanye iindawo zesakhiwo zokuhambisa ulwelo kumashishini oomatshini, ngelixa iingqiniba ezidityanisiweyo zisetyenziswa ikakhulu kushishino lolwakhiwo, olufana nolwelo olunoxinzelelo oluphantsi, njengamanzi nomoya oxinanisiweyo. Nangona kunjalo, i-penstocks echaphazelekayo ayinamthungo.

4. Umahluko wobungakanani obukhoyoUninzi lwabavelisi beengqiniba zemibhobho engenamthungo eTshayina, ubungakanani bengqiniba zemibhobho engenamthungo yi-intshi ezingama-24 kunye nedayamitha yangaphandle yi-609.6 mm. Ngokwahlukileyo, akukho mda kwiigophe ezidityanisiweyo, ezinokusuka kwi-1-1/2 intshi 48.3mm ukuya kwi-100 intshi 2540mm.

5. Amaxabiso ahlukeneyoNjengoko inkqubo yokuvelisa i-seamless inzima kakhulu, ixabiso libiza kakhulu kune-elbow edibeneyo, kwaye i-joint yenziwe ngokukodwa nge-steel plate (i-steel strip) nge-welding yesibini, engabizi kwaye isetyenziswa ngokubanzi.
