Chiyambi cha Zamalonda

Kuwonetsa mipope yathu yayikulu yamadzi yothandiza kwambiri, yopangidwa kuti ikwaniritse zosowa zosiyanasiyana zamafakitale osiyanasiyana. Zopangidwa mu fakitale yathu yamakono ku Cangzhou, m'chigawo cha Hebei, kampani yathu yakhala ikutsogola pakupanga zitoliro kuyambira pomwe idakhazikitsidwa mu 1993. Ndi dera la 350,000 masikweya mita ndi chuma chonse cha RMB 680 miliyoni, ndife onyadira kukhala ndi antchito odzipereka a akatswiri aluso 680.

Zathuchitoliro chachikulu chamadziamapangidwira kuti azigwira bwino ntchito pazovuta kwambiri monga zoyendera madzi ndi mizere ya gasi. Timamvetsetsa kuti mafotokozedwe a mapaipiwa, kuphatikiza ma welds ndi mapangidwe a spiral seam, amagwira ntchito yofunika kwambiri pakugwira ntchito kwawo komanso kudalirika. Ichi ndichifukwa chake timagwiritsa ntchito njira zotsogola zopangira zinthu komanso njira zowongolera kuti zitsimikizire kuti mapaipi athu amakwaniritsa miyezo yapamwamba kwambiri yamakampani.

Mitsinje yathu yamadzi idapangidwa kuti ikhale yothandiza kwambiri komanso yosunthika, ndipo itha kugwiritsidwa ntchito m'malo osiyanasiyana, kuwapangitsa kukhala abwino kwa makontrakitala, ma municipalities, ndi mafakitale. Kaya mukukhazikitsa cholumikizira chamadzi chatsopano kapena mukukweza chingwe cha gasi chomwe chilipo, mapaipi athu amapereka kulimba komanso mphamvu zomwe zimafunikira kuti zikwaniritse zofuna za polojekiti iliyonse.

Ubwino wa Zamankhwala

Ubwino umodzi waukulu wa mipope yamadzi yayikulu ndikugwiritsa ntchito kwawo kwakukulu. Amapangidwa kuti akwaniritse zofunikira zamadera osiyanasiyana, kuwapanga kukhala oyenera kumadera akumidzi komanso akumidzi. Kusinthasintha kwa mapaipiwa kumawalola kuti agwiritsidwe ntchito pazinthu zosiyanasiyana, kuchokera kumadzi okhala m'nyumba kupita kumayendedwe amafuta amafuta. Kusinthika kumeneku ndikofunikira kwa ma municipalities ndi mabizinesi momwemo, chifukwa kumathandizira kagulitsidwe ndi kukhazikitsa.

Kuperewera kwa katundu

Mayendedwe a mapaipiwa angakhudzidwe ndi zinthu monga nthaka, kusinthasintha kwa kutentha, ndi kupanikizika. Mwachitsanzo, mipope yowotcherera imatha kukhala ndi dzimbiri m'malo ena, pomwe mapaipi ozungulira ozungulira sangakhale olimba kwambiri akamapanikizika kwambiri. Kumvetsetsa zolephera izi ndikofunikira kwa mainjiniya ndi okonza mapulani kuti awonetsetse kuti chitoliro choyenera chimasankhidwa pa ntchito iliyonse.

Kugwiritsa ntchito

Kufunika kwa mabwalo odalirika, apamwamba kwambiri amadzi pakupanga malo omwe akukulirakulira sikungapitirire. Odziwika chifukwa cha ntchito zawo zapamwamba, mapaipiwa ndi ofunikira pazinthu zosiyanasiyana, kuphatikizapo mapaipi amadzi ndi gasi. Mafotokozedwe awo, monga ma welds ndi mapangidwe a spiral seam, amatenga gawo lalikulu pakuwonetsetsa kuti magwiridwe antchito ndi moyo wabwinobwino.

Mapaipi athu akuluakulu amadzi amagwiritsidwa ntchito m'njira zosiyanasiyana, zomwe zimawonekera m'madera osiyanasiyana. Kaya ndi njira yoperekera madzi mumsewu kapena njira yogawa gasi, mapaipi athu amatha kupirira zovuta zomwe zimagwiritsidwa ntchito tsiku ndi tsiku ndikusunga bwino. Welded ndichitoliro cha msokozosankha zimapereka kusinthasintha mukugwiritsa ntchito, kulola mayankho kusinthidwa kuti akwaniritse zofunikira za polojekiti.

FAQ

Q1. Kodi chitoliro chachikulu chamadzi chimapangidwa ndi chiyani?

Mabomba amadzi nthawi zambiri amapangidwa ndi zinthu zolimba monga chitsulo, PVC ndi HDPE. Kusankhidwa kwa zinthu kumadalira ntchito yeniyeni ndi chilengedwe.

Q2. Kodi mapaipi owotcherera ndi ma spiral seam mapaipi ndi chiyani?

Welded chitoliro aumbike mwa kulumikiza m'mbali ziwiri za chitoliro pamodzi, amene ali amphamvu ndi kutayikira-umboni dongosolo. Spiral seam pipe imapangidwa pogubuduza chingwe chachitsulo chathyathyathya kukhala chubu, chomwe chimakhala ndi kusinthasintha kwakukulu pakupanga ndi kugwiritsa ntchito.

Q3. Kodi ndimasankha bwanji payipi yoyenera ya polojekiti yanga?

Ganizirani zinthu monga mtundu wamadzimadzi omwe akutumizidwa, kukakamizidwa, komanso momwe chilengedwe chikuyendera. Kufunsana ndi katswiri kungakuthandizeninso kuonetsetsa kuti mwasankha chubu labwino kwambiri pazosowa zanu.
