Wopanga Mapaipi Achitsulo Otsogola & Wopereka Ku China |

Kodi Chitoliro cha Chitsulo Ndi Chiyani?

Kufotokozera bwino kukula kwa chubu chachitsulo kumafunika kuphatikiza magawo angapo:

Diameter yakunja (OD)

The awiri kunja kwa chitoliro zitsulo, kawirikawiri anasonyeza m'mimba mwake mwadzina (DN) kapena mwadzina chitoliro kukula (NPS).

Kukula Kwapaipi Kwadzina (NPS) vs. Nominal Diameter (DN)

NPS ndi kukula mwadzina kutengera mainchesi, pomwe DN ndi m'mimba mwake mwadzina mu mamilimita.Ubale wotembenuka ndi wosavuta: mtengo wa DN ndi wofanana ndi mtengo wa NPS wochulukitsidwa ndi 25.4 (mm/inch) kuti azungulire zotsatira.

ndi miyeso ya chitoliro chachitsulo

M'malo mwake, kulemberana makalata pakati pa miyezo ya NPS ndi DN kumakhazikika pamiyeso yokhazikika yomwe yakhazikitsidwa.

Makulidwe a Khoma (WT)

Kuchuluka kwa khoma la chitoliro.Kwa chitoliro chokhazikika, makulidwe a khoma nthawi zambiri amagwirizanitsidwa ndi Ndandanda ya chitoliro, mwachitsanzo Ndandanda 40 kapena Ndandanda 80, pamene mfundo zazikulu zimasonyeza makoma okhuthala.

Utali

Kutalika kwa chitoliro chachitsulo, chomwe chingathe kukhazikitsidwa kapena mwachisawawa, malingana ndi kupanga ndi ntchito zofunikira.Utali wamba ndi 6 mita ndi 12 mita.

Zakuthupi

Miyezo ya zinthu ndi magiredi a chitoliro chachitsulo, monga ASTM A106 Gulu B, API 5L Gulu B, ndi zina zotere.

Miyezo

The dimensional miyezo ya carbon ndi zitsulo zosapanga dzimbiri chitoliro makamaka kutsatira ASME B36.10M (carbon ndi aloyi zitsulo) ndi B36.19M (stainless zitsulo chitoliro).

Matebulo Kukula kwa Chitoliro ndi Magawo Olemera (WGT)

perekani njira yokhazikika yofotokozera makulidwe a khoma la chitoliro pansi pa Madongosolo osiyanasiyana, komanso kugawa magiredi olemera monga STD, XS, XXS, ndi ena.

Kuchuluka kwa khoma la chitoliro kumakhudza mwachindunji miyeso yamkati ndi kulemera kwa chitoliro.Kuchuluka kwa khoma ndikofunikira chifukwa kumatsimikizira kuchuluka kwa kuthamanga kwamkati komwe chitoliro chingathe kupirira.

Nambala ya ndondomeko

Njira yosonyezera makulidwe a khoma la chitoliro, nthawi zambiri monga Ndandanda 40 ndi 80, imatanthawuza makulidwe a khoma la chitoliro choperekedwa kunja.

Chiŵerengero cha chiwerengero cha ndandanda ndi motere:

Fomula ya Ndandanda No.

Chifukwa cha kuthekera kwawo kulimbana ndi zovuta zanthawi zonse, mapaipi achitsulo a Pulogalamu 40 ndi Pulogalamu 80 amafunikira m'mafakitale osiyanasiyana.Popeza kuti mapaipiwa amapangidwa kuti athe kupirira zitsenderezo zokulirapo, kaŵirikaŵiri amafunikira mochuluka kuti akwaniritse zofunika za mafakitale osiyanasiyana.
