Nazi mfundo zazikulu za mapaipi achitsulo a LSAW:
Njira Yowotcherera: Mapaipi achitsulo a LSAW amapangidwa pogwiritsa ntchito njira yowotcherera ya arc imodzi, iwiri, kapena itatu. Njirayi imalola kuti ma welds apamwamba kwambiri, yunifolomu azitha kutalika kwa chitoliro.
Longitudinal Seam: Njira yowotcherera imapanga msoko wotalika mu chitoliro chachitsulo, zomwe zimapangitsa kuti pakhale zomangamanga zolimba komanso zolimba zomwe zimayenera kugwiritsidwa ntchito zosiyanasiyana.
Kuthekera Kwakukulu Diameter: Mapaipi achitsulo a LSAW amadziwika kuti amatha kupanga ma diameter akulu, kuwapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimafunikira kunyamula madzi ambiri kapena kugwiritsidwa ntchito pamapangidwe.
Mapulogalamu: Mapaipi achitsulo a LSAW amagwiritsidwa ntchito kwambiri popanga mapaipi otumizira mafuta ndi gasi, milu, kuthandizira pakumanga, ndi ntchito zina zamafakitale ndi zomangamanga.
Kutsata Miyezo: Mipope yachitsulo ya LSAW idapangidwa ndikupangidwa kuti ikwaniritse miyezo yamakampani ndi mafotokozedwe, kuwonetsetsa kuti ikukwaniritsa zofunikira pakugwiritsa ntchito komanso momwe chilengedwe chimakhalira.
