Kuyamba kwa dzinja kwadutsa, ndipo pamapeto pake zatsika pang'onopang'ono, makamaka kumadera akumpoto. Kutentha kumakhala kotsika nthawi yozizira, komanso momwe kumasungirako nthawi yokhazikika pamayendedwe oyenda kwa Step kwakhala vuto kwa aliyense. Masiku ano, Nobeth adzalankhula nanu za kusankha kwa mapaipi a Steam Mapikisano.
Ngakhale pali zida zambiri zotchinga, zida zosiyanasiyana zimakhala ndi ntchito zosiyanasiyana pakugwiritsa ntchito. Zipangizo zokomera zomwe zimagwiritsidwa ntchito m'mapaipi otentherera ndizosavuta, koma zida zotuwa zimagwiritsidwa ntchito pa mapaipi otentherera? Nthawi yomweyo muyenera kudziwa zomwe zida zotupitsa za mapaipi amtundu ndi, kuti muthe kusankha zinthu zapamwamba kwambiri.
Kodi ndi zinthu zotsitsimurika ziti zomwe zimagwiritsidwa ntchito pa mapaipi anyezi?
1. Malinga ndi Artict 7.9.3 Mwa GB50019-2003 "Kupanga Khodi Yoyatsa ndi Kusankha Zinthu Zazitsulo Zapatali, Kusankha Zinthu Zosavuta Kwambiri Zipangizo zamagetsi; Zipangizo zotupitsa ziyenera kukhala zophatikizika kapena zayamtunda; Makulidwe a chitoliro cha chitoliro chikuyenera kuwerengeredwa ndikuwonetsetsa malinga ndi makulidwe azachuma mu GB8175 "Malangizo a kapangidwe ka zida ndi chitoliro chotenthetsera.
2. Zinthu zomwe zimagwiritsidwa ntchito kwambiri zimaphatikizapo cork, aluminium silika, polystyrene ndi polyurethane. Ndi iti yomwe mungagwiritsire ntchito yomwe iyenera kulingaliridwa malinga ndi zovuta za dongosolo la masipu ndi mtengo wa zotuwa. Nthawi zambiri, zinthu zotsetsereka zomwe zimagwiritsidwa ntchito m'dongosolo ziyenera kukhala zofanana.
3. Chifukwa kugwiritsa ntchito mapangidwe okumba otuwa ndi osavuta pakumanga ndipo matenthedwe osokoneza bongo ndi abwino kuposa omwe amakonzedwa pamalopo, motero amagwiritsidwa ntchito kwambiri. Komabe, kwa mtundu uwu wa kusanjana, ngati chotchinga cha Vapor sichikuthandizidwa bwino, mpweya wamadzi mlengalenga chimayenda mu chipembedzocho, potero kuwononga magwiridwe antchito osungunuka.
Kodi zida zotupa ndi ziti?
1.
Mapaipi a utoto amagwiritsidwa ntchito kwambiri chifukwa cha kuchuluka kwa ma boloni kapena zida m'mapaipi monga Petrokemical, metaldurgy, zomanga, komanso kapangidwe kake. Nthawi zina amagwiritsidwa ntchito kwambiri m'makoma ogawana m'makampani omanga, ndipo chifukwa cha nyumba yomanga ndi khoma komanso mitundu ina yamitundu ina. Khalani otentha. Komabe, m'magulu opanga magetsi, ogulitsa materochemical, osuta, ndi zina, zotchinga ndi zamagetsi, makamaka ma pichelines okhala ndi zojambula zazing'ono. Mapapu a ubweya wamadzi amchere amatha kukhazikitsidwa mwachangu. Ili ndi katundu wapadera monga kukana chinyezi, madzi mobwerezabwereza ndi kutentha kwa kutentha. Ndioyenera kugwiritsa ntchito nkhalango zamvula. Imakhala ndi kutentha kwa madzi.
2. Ubweya wagalasi,
Mafuta agalasi ali ndi mawonekedwe abwinobwino, kachulukidwe kakang'ono kwambiri, komanso kuchepa kwa mafuta. Maluwa agalasi nawonso ali ndi vuto lalikulu kwambiri ndipo amakhala ndi mankhwala abwino opangira zachilengedwe. Makhalidwe osinthira a ubweya wagalasi ndi chifukwa chotupa cha mpweya, mapaipi opopera, ma boiler ndi mapaipi a Steam.
3. Urethane, Polyirethane, omwe amagwiritsidwa ntchito kwambiri popanga ozizira, matikiti okhala kapena mabokosi atsopano. Itha kugwiritsidwanso ntchito ngati kutentha kutentha kwa masamba a santel steel. Polyirethane nthawi zina amagwiritsidwa ntchito m'matanki a petrochemical. Polyurethane nawonso ali ndi ntchito ya zokutira ndi zozizira, ndipo zimagwiritsidwa ntchito ku serochemical komanso zitsulo. Zimagwiritsidwa ntchito kwambiri pakutetezera kunja kwa malo osiyanasiyana pansi panthaka zoikidwa m'manda mwachindunji.
