Kuyang'anira: Nthawi zambiri, mapaipi achitsulo oyendetsa madzimadzi amayenera kuwunika momwe zinthu ziliri, kuyesedwa kwamphamvu, kuyesa kukhazikika komanso kuyesa kuthamanga kwamadzi. Kuphatikiza pa mayeso omwe amayenera kuchitidwa pa mapaipi achitsulo oyendetsa madzimadzi, mapaipi achitsulo a GB5310, GB6479 ndi GB9948 amayeneranso kuyesedwa pakukulitsa ndi kuyesa zotsatira; zofunikira zoyendera zopangira mapaipi atatu azitsulowa ndi okhwima. Muyezo wa GB6479 umapanganso zofunikira zapadera pakulimba kwazinthu zotsika kutentha. Kuphatikiza pa zomwe zimafunikira pakuyesa mapaipi achitsulo pamayendedwe amadzimadzi, mapaipi achitsulo a GB3087 muyezo amafunikiranso kuyesedwa kozizira. Kuphatikiza pa zomwe zimafunikira pakuyezetsa mapaipi achitsulo pamayendedwe amadzimadzi, mapaipi achitsulo a GB/T8163 muyezo amafunikira kuti ayesedwe kukulitsa ndikuyezetsa kozizira molingana ndi mgwirizano. Zofunikira zopangira mapaipi awiriwa sizolimba monga atatu oyamba. Kupanga: Mapaipi achitsulo a GB/T/8163 ndi GB3087 miyezo nthawi zambiri amasungunulidwa ndi ng'anjo yotseguka kapena chosinthira, ndipo zida zawo zonyansa ndi zolakwika zamkati ndizochulukirapo. GB9948 nthawi zambiri imasungunuka ndi ng'anjo yamagetsi. Ambiri aiwo awonjezera njira yoyeretsera kunja kwa ng'anjo, ndipo mapangidwe ake ndi zolakwika zamkati ndizochepa. Miyezo ya GB6479 ndi GB5310 yokha imafotokoza zofunikira pakuyenga kunja kwa ng'anjo, zokhala ndi zonyansa zochepa komanso zolakwika zamkati, komanso zinthu zapamwamba kwambiri. Miyezo yopangira zida zomwe zili pamwambazi zili ndi dongosolo kuchokera kutsika mpaka kumtunda: GB/T8163
