ZOPANGIRA ZA BUTWELD ZONSE

Kuyika chitoliro kumatanthauzidwa ngati gawo lomwe limagwiritsidwa ntchito mu dongosolo la mapaipi, kusintha njira, nthambi kapena kusintha kwa mainchesi a chitoliro, ndipo limalumikizidwa ndi makina ku dongosololi. Pali mitundu yosiyanasiyana ya zoyika ndipo ndizofanana kukula ndi nthawi zonse monga chitoliro.

Zopangira zimagawidwa m'magulu atatu:

Zolumikizira za Buttweld (BW) zomwe miyeso yake, kulekerera kwake ndi zina zotero zimafotokozedwa mu miyezo ya ASME B16.9. Zolumikizira zopepuka zolimbana ndi dzimbiri zimapangidwa ku MSS SP43.
Zolumikizira za Socket Weld (SW) Class 3000, 6000, 9000 zafotokozedwa mu miyezo ya ASME B16.11.
Zipangizo zolumikizidwa ndi ulusi (THD), kalasi 2000, 3000, 6000 zimafotokozedwa mu miyezo ya ASME B16.11.

Kugwiritsa Ntchito Zopangira za Buttweld

Njira yopangira mapaipi pogwiritsa ntchito zomangira za buttweld ili ndi ubwino wambiri poyerekeza ndi mitundu ina.

Kulukira cholumikizira pa chitoliro kumatanthauza kuti sichingatuluke madzi nthawi zonse;
Kapangidwe kachitsulo kosalekeza komwe kamapangidwa pakati pa chitoliro ndi cholumikizira chimawonjezera mphamvu ku dongosololi;
Kusalala kwa mkati ndi kusintha pang'onopang'ono kwa njira kumachepetsa kutayika kwa mphamvu ndi kugwedezeka ndipo kumachepetsa mphamvu ya dzimbiri ndi kukokoloka kwa nthaka;
Dongosolo lolumikizidwa limagwiritsa ntchito malo ochepa.
