Monga chinthu chofunikira kwambiri pakupanga mapaipi amakono, mapaipi apulasitiki{0}okutidwa ndi zitsulo amagwira ntchito yofunika kwambiri pomanga nyumba zapakhomo ndi zapadziko lonse lapansi chifukwa cha kusachita dzimbiri komanso mphamvu zamakina. Kumvetsetsa kapangidwe kawo kofunikira ndikofunikira kuti mumvetsetse mawonekedwe aukadaulo ndi mtengo wamsika wamtunduwu.
Malinga ndi kamangidwe kake, mapaipi apulasitiki-zokutidwa ndi zitsulo nthawi zambiri amapangidwa kuchokera ku-mpweya wabwino kwambiri wa carbon structural steel kapena kutsika-alloy high{3}}chitsulo cholimba. Zopangidwa ndi kugudubuzika kozizira kapena kotentha, zitsulo izi sizingokhala ndi mphamvu zophatikizika bwino komanso zimagwirizana ndi zofunikira pakuyika m'malo osiyanasiyana. Magiredi achitsulo monga Q235B ndi Q345B ndiye maziko a pulasitiki-mapaipi achitsulo okutidwa chifukwa cha mtengo wake wapamwamba-ogwira ntchito bwino. Magawo a carbon steel awa amathandizidwa{11}}tu kuti achotse wosanjikiza wa surface oxide, kupanga mawonekedwe abwino a zokutira zapulasitiki.
Pankhani ya zokutira zogwirira ntchito, mapaipi apulasitiki-zokutidwa ndi zitsulo amakutidwa mkati ndi kunja ndi thermoplastics kapena thermosetting resins. Chophimba chamkati chimakhala chopangidwa ndi chakudya-grade polyethylene (PE) kapena epoxy resin (EP). High-polyethylene yolimba kwambiri imapereka kukhazikika kwamankhwala ndipo imalimbana bwino ndi zinthu zowononga acid komanso zamchere. Kupaka utoto wa epoxy, chifukwa cha kuchuluka kwake kwa maselo, kumawonetsa zaukhondo ponyamula madzi akumwa. Chitetezo chakunja chimakhala chopangidwa ndi UV-popanda pulasitiki yosinthika ya polyethylene, kuonetsetsa kuti chitolirocho sichimakalamba komanso kusweka pakapita nthawi-panja.
Zochitika zapadera zogwiritsira ntchito zalimbikitsa chitukuko chamakono cha zipangizo zophatikizika. Kuti zikwaniritse zosowa za{1}}zoyendera zamadzi otentha kwambiri, zinthu zina zimagwiritsa ntchito-temperature modified polypropylene (PP-R) ngati mpanda wamkati. Kuti musamavute m'migodi, zokutira zokhala ndi tinthu tating'ono tadothi titha kuwonjezera moyo wa ntchito ya mapaipi ndi 3-5. Kuwongolera kwazinthu izi kumasunga ubwino wokhala ndi mphamvu zamapaipi achitsulo pamene akupereka ntchito yapadera pazochitika zinazake zogwirira ntchito.
Kuchokera kumalingaliro amalonda apadziko lonse lapansi, kusankha kwazinthu zamapaipi apulasitiki-zokutidwa ndi zitsulo zimakhudza kwambiri kupikisana kwa malondawo. Zopangidwa zomwe zimagwirizana ndi miyezo yapadziko lonse lapansi monga ASTM ndi ISO, kuphatikiza ndi SGS-malipoti oyezetsa zinthu zovomerezeka, zakhala kiyi yopezera mwayi-msika wapamwamba ku Europe ndi United States. Pamisika yomwe ikubwera ngati Southeast Asia ndi Middle East, kuphatikiza kwazinthu komwe kumawononga ndalama zambiri ndi ntchito zoyambira ndikosavuta kukopa ogula.
Kumvetsetsa zinthu zofunika kwambiri za pulasitiki-zokutidwa ndi chitoliro chachitsulo sikumangothandiza kumvetsetsa zaukadaulo wazinthu komanso kumapatsa magulu amalonda akunja njira zolimbikitsira malonda, potero amapeza zabwino mumpikisano wamisika yapadziko lonse lapansi.
