Kodi chitoliro chachikulu?

makampani Modern umabala mapaipi a diameters zosiyanasiyana zimene ntchito zosiyanasiyana. Zitsulo-mpukutu ndi yaing'ono m'mimba mwake pafupifupi ntchito ku nyumba za mizinda yambiri. Ndipo chipatso cha m'mimba mwake lalikulu Kawirikawiri ntchito mauthenga zofunikira ndi mafuta ndi gasi mapaipi. Kusankha ina chitoliro chitoliro awiri zimadalira zolinga, ndi m'litali ndi zikhalidwe opaleshoni.

mitundu

Panopa, mapaipi zitsulo lalikulu-m'mimba mwake anasiyanitsidwa malinga ndi njira yopanga awo. Pali osakwatiwa-msoko, amene anapanga pepala zitsulo kudzera mwa kukana kuwotcherera. Iwo ndi awiri a mamilimita kuchokera 114 mpaka 530.

Mtundu wachiwiri wa chitoliro wotchedwa mwauzimu. Amachita zitsulo adagulung'undisa ntchito magetsi Arc kuwotcherera. Dzinali amapereka lingaliro la momwe msoko ndi ili, limene chomaliza mankhwala. The awiri a mankhwala amenewa ali mu uthunthu 159-820 mm.

Mtundu wachitatu ndi yaikulu - ndi diameters kuyambira 530 mamilimita kwa 1420 mm. Iwo malonda zilipo limodzi kotenga molunjika msoko, amene ali Arc kuwotcherera.

Komanso, mu ndondomeko mafakitale angathe kuchitidwa m'mbali - yokonza ndi deburring. Izi zikhoza kupangidwa ndi mipope popanda edgings.

ntchito

Kusankha zipangizo anaika pa siteji kapangidwe ka zinthu zosiyanasiyana. Popeza ntchito yomanga thunthu mapaipi kwa hydrocarbon feedstock, amakonda kugwiritsa ntchito mipope lalikulu m'mimba mwake. Chitoliro 1420 mamilimita amalola kulenga mwa ichi patency ngalande popanga zipangizo zopangira ndipo, chotero, bungwe migodi sadzalola wogula. mitengo ofanana kuyembekezera okonza ndi awiri machubu zing'onozing'ono - 900, 920 kapena 1020 mm.

Mu midzi, pomanga mapaipi kuti kusamutsira zopangira bwino yosayenera chubu 920 kapena 1200 mm. Ichi ndi chifukwa chakuti mipope ngati zambiri yaying'ono kwambiri aime motsutsa cityscape (pamene chitoliro kunja), ndi mobisa ndondomeko kuika - zochepa kuya kufunika dzenje (choncho muyenera ndalama zochepa ntchito kwa kudzaza ndi ejection maenje).

Komanso mu chitoliro m'madera zitsulo 920h12 kapena 1000 mamilimita angagwiritsidwe ntchito zipangizo nyumba (mipope madzi, zimbudzi). Mwachitsanzo ovomereza mmalo mipope zitsulo a mipope kuponya chitsulo 920h12 bwino olembedwa apa http://steel-snab.ru.

Plus, ngakhale deducting ndalama pa kukumba, backfilling wa kunkhondo, mtengo wa malipiro ogwira ntchitoyi ntchito, icho chiri kwambiri. mtengo zawo n'chozama kuposa chitsulo chosungunula. Koma moyo wa chitoliro zitsulo ndi poyerekeza kuti cha Akhristu kuponya chitsulo. Koma wamphamvu kuposa chitsulo chosungunula, zitsulo - iwo sali owopa kudabwitsa choncho zochepa zowonongeka afotokoze akagwira ntchito. Ubwino wina wa mankhwala zitsulo isanafike kusita mu dongosolo nyumba - kukana mkulu dzimbiri.
