Izimpi zangaphandle ziyaqhubeka, kodwa umnotho wezwe uyaqhubeka nokwethula izinqubomgomo ezinhle, futhi ohlangothini lwezimboni, amanani ensimbi afinyelele amazinga aphezulu kaningi. Ama-Bifocal akhuphuke ngenxa yokwanda kwesidingo ngesikhathi sokushisa, ukwesekwa kwezindleko kube namandla, futhi amanani ensimbi aqhubeke nokwenyuka. , ukwesaba isidingo esiphezulu sokugcina kukhuphuke, imisebenzi yokugcwalisa kabusha imakethe ikhuphuke, ukukhiqizwa kwensimbi eluhlaza nsuku zonke kwehlile, ukungeniswa kwensimbi kwehle, omunye umjikelezo wokuthengiswa kwenhlabathi usuqalile, futhi imakethe yendawo izinzile futhi inamandla. Ngokombono ophelele, amanani ensimbi kulindeleke ukuthi aqine futhi aqine kusasa.

I-Sanon Pipe Industry okwamanje inamapayipi ensimbi alandelayo esitokweni:

Ipayipi lensimbi elingenamthungo lama-boilers anengcindezi ephansi nephakathi - GB/T3087-200810#, esetshenziselwa amapayipi omusi ashisayo kakhulu, amapayipi amanzi abilayo, amapayipi odonga apholiswe ngamanzi kanye namapayipi omusi ashisayo ama-boiler e-locomotive, amapayipi amakhulu omusi, amapayipi amancane omusi kanye namapayipi ezitini ezigobile, njll. .
