Kufotokoza molondola kukula kwa chubu chachitsulo kuyenera kuphatikizapo magawo angapo ofunikira:
Chidutswa cha Kunja (OD)
M'mimba mwake wakunja wa chitoliro chachitsulo, nthawi zambiri amafotokozedwa ngati m'mimba mwake wodziwika (DN) kapena kukula kwa chitoliro chodziwika (NPS).
Kukula kwa Chitoliro Chodziwika (NPS) vs. Kukula kwa Chitoliro Chodziwika (DN)
NPS ndi kukula kwa nominella kutengera mainchesi, pomwe DN ndi m'mimba mwake wa nominella mu mamilimita. Ubale wosinthira ndi wosavuta: mtengo wa DN ndi wofanana ndi mtengo wa NPS wochulukitsidwa ndi 25.4 (mm/inchi) kuti uzungulire zotsatira.
Mwachidule, kugwirizana pakati pa miyezo ya NPS ndi DN kumadalira kwambiri matebulo ofanana omwe akhazikitsidwa.
Kukhuthala kwa Khoma (WT)
Kukhuthala kwa khoma la chitoliro. Pa chitoliro chokhazikika, makulidwe a khoma nthawi zambiri amagwirizanitsidwa ndi Ndandanda ya chitoliro, mwachitsanzo Ndandanda 40 kapena Ndandanda 80, pomwe mitengo yayikulu imasonyeza makoma okhuthala.
Utali
Kutalika kwa chitoliro chachitsulo, chomwe chingakhazikike kapena chosasinthika, kutengera zomwe zimapangidwa ndi zomwe zimagwiritsidwa ntchito. Kutalika kofanana ndi mamita 6 ndi mamita 12.
Zinthu Zofunika
Miyezo ya zinthu ndi magiredi a chitoliro chachitsulo, monga ASTM A106 Giredi B, API 5L Giredi B, ndi zina zotero. Miyezo iyi imafotokoza kapangidwe ka mankhwala ndi mawonekedwe enieni a chitolirocho.
Miyezo
Miyezo ya miyeso ya chitoliro cha kaboni ndi chitsulo chosapanga dzimbiri imatsatira makamaka ASME B36.10M (chitsulo cha kaboni ndi alloy) ndi B36.19M (chitoliro chachitsulo chosapanga dzimbiri).
Matebulo a Kukula kwa Mapaipi ndi Matebulo a Kulemera (WGT)
Perekani njira yokhazikika yofotokozera makulidwe a khoma la chitoliro pansi pa Ma schedule osiyanasiyana, komanso magulu a kulemera monga STD, XS, XXS, ndi zina.
Kukhuthala kwa khoma la chitoliro kumakhudza mwachindunji kukula ndi kulemera kwa chitolirocho. Kukhuthala kwa khoma n'kofunika chifukwa kumatsimikizira kuchuluka kwa mphamvu yamkati yomwe chitolirocho chingapirire.
Nambala ya ndondomeko
Njira yosonyezera makulidwe a khoma la chitoliro, monga momwe zilili ndi Ndandanda 40 ndi 80, imatanthauza makulidwe a khoma okhazikika komanso olimbikitsidwa a chitolirocho pa mulingo wakunja woperekedwa.
Kuwerengera koyerekeza kwa nambala ya ndondomeko ndi motere:
Chifukwa cha kuthekera kwawo kupirira kupsinjika kwanthawi zonse, mapaipi achitsulo a Schedule 40 ndi Schedule 80 nthawi zambiri amafunikira m'mafakitale osiyanasiyana. Popeza mapaipi awa adapangidwa kuti apirire kupsinjika kwakukulu, nthawi zambiri amafunikira kwambiri kuti akwaniritse zosowa za mafakitale osiyanasiyana.

Chifukwa chake, chitsanzo chonse cha kukula kwa chitoliro chachitsulo chingakhale "NPS 6 inchi, Ndandanda 40, ASTM A106 Giredi B, Kutalika mamita 6". Izi zikuyimira chitoliro chachitsulo chokhala ndi mainchesi 6 m'mimba mwake, Ndandanda 40, yopangidwa motsatira miyezo ya ASTM A106 Giredi B, ndipo kutalika kwake ndi mamita 6.
