Mipope yachitsulo yosasunthika ikhoza kugawidwa mu ASTM American mipope yachitsulo yopanda phokoso, DIN German mipope yachitsulo yopanda phokoso, mipope ya JIS Japanese yokhazikika, mapaipi amtundu wa GB opanda zitsulo, mipope yachitsulo ya API ndi mitundu ina malinga ndi miyezo yawo. Mapaipi a ASTM American standard seamless zitsulo amagwiritsidwa ntchito kwambiri padziko lonse lapansi, ndipo mitundu yawo ndi yosiyanasiyana. Magawo oyenera a ASTM mapaipi achitsulo osasunthikaASTM A179/ 179m/sa179/sa-179m mipope yachitsulo yopanda msoko yaku America yalembedwa motere

Njira yopangira chitoliro chopanda zitsulo. Malinga ndi momwe amapangira, mapaipi achitsulo opanda msoko amagawidwa m'mapaipi achitsulo osakanizika otentha otenthedwa, mipope yachitsulo yosakanizidwa ndi kuzizira, mipope yachitsulo yokhomeredwa ndi yotambasulidwa, ndi mapaipi achitsulo opanda msoko otuluka molunjika. Njira ziwiri zoyamba zimagwiritsidwa ntchito popanga mapaipi achitsulo osasunthika, omwe m'mimba mwake amakhala 8-406, ndipo makulidwe a khoma nthawi zambiri amakhala 2-25; Njira ziwiri zotsirizirazi zimagwiritsidwa ntchito popanga mapaipi azitsulo amtundu wokhuthala wokhala ndi mipanda, omwe m'mimba mwake nthawi zambiri amakhala 406-1800, ndipo makulidwe a khoma ndi 20mm-220mm. Malingana ndi ntchito yake, ikhoza kugawidwaopanda zitsulo mapaipi kwa nyumba, mipope yachitsulo yopanda phokoso yamadzimadzi, mapaipi achitsulo opanda msoko a boilers,ndimapaipi achitsulo opanda msoko a mapaipi amafuta.
