Zoyenera Kutumizira
Kutengera momwe amaperekera komanso mulingo wa PSL, X60 ikhoza kugawidwa motere:
PSL1: x60 kapena L415;
PSL2: X60N, X60Q, X60M kapena L415N, L415Q, L415M.
N: Imawonetsa kukhazikika kwa zinthuzo.Mwa kutenthetsa zitsulo mpaka kutentha kwina kutsatiridwa ndi kuziziritsa kwa mpweya.Kupititsa patsogolo microstructure ndi makina katundu wa zitsulo ndi kuonjezera kulimba kwake ndi kusasinthasintha.

Ngati mukuwona kuti mawu achidulewa ndi ovuta kumva, onani zomwe talembazowamba achidule kwa mipope zitsulo.
Ubwino wa SAWL (LSAW)
Ngati mukufuna lalikulu m'mimba mwake wandiweyani khoma zitsulo chitoliro, kusankha choyamba ndiMtengo wa SAWL (Mtengo wa LSAW) chitoliro chachitsulo.LSAW chitoliro chachitsulo chingapangidwe kukula kwake mpaka 1500mm m'mimba mwake ndi 80mm mu makulidwe a khoma, omwe amatha kukwaniritsa zofunikira za mapaipi akutali kwa ntchito zazikulu.
Kuphatikiza apo, panthawi yopanga, chitoliro chachitsulo cha LSAW chimatenga mbali ziwiri zowotcherera arc (Chithunzi cha DSAW) ndondomeko, yomwe imatsimikizira ubwino wa weld seam.
