Ipayipi Elihlanganisiwe Lomthungo Ojikelezayo GBT9711 2011PSL2

Incazelo emfushane:

Emkhakheni we-ipayipi likawoyela negesis, ukusetshenziswa kwamapayipi ahlanganisiwe ajikelezayo kuya ngokuya kuvama. Eyaziwa nangokuthi ipayipi lomugqa wegesi, ipayipi lokusaha, kanye nepayipi likawoyela negesi, la mapayipi aguquguqukayo enziwa kusetshenziswa amasu okushisela ahlukile anikeza izinzuzo eziningi ekuthuthweni kukawoyela, igesi yemvelo, kanye nolunye uketshezi. Kule bhulogi, sizohlola ukuguquguquka kwamapayipi ahlanganisiwe ajikelezayo nokuthi kungani eyindlela yokuqala yokukhetha amaphrojekthi amaningi okufaka amapayipi.

Sithumelele i-imeyili

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Siyajabula ukwethula umkhiqizo wethu omusha,ipayipi elihlanganisiwe lomthungo ojikelezayoLo mkhiqizo omusha onemisebenzi eminingi wenziwa ngokugoqa insimbi eyakhiwe ngekhabhoni ephansi noma imichilo yensimbi eyakhiwe nge-alloy ephansi ibe yizimbobo zamashubhu nge-engeli ethile ejikelezayo, bese sihlanganisa imiphetho yamashubhu. Le nqubo yokukhiqiza eyingqayizivele isivumela ukuthi sikhiqize amapayipi ensimbi anobubanzi obukhulu ngemichilo emincane.

Kwa-Cangzhou Spiral Steel Pipes Group Co., Ltd., siyaziqhenya kakhulu ngezikhungo zethu zesimanje kanye nobuchwepheshe obusezingeni eliphezulu. Njengoba ihlanganisa indawo engamamitha-skwele angu-350,000 kanye nempahla iyonke engama-yuan ayizigidi ezingu-680, isibe ngumholi embonini. Njengoba inethimba elizinikele labasebenzi abangu-680, ngemizamo engapheli, inkampani inomkhiqizo waminyaka yonke wamathani angu-400,000 wamapayipi ensimbi ajikelezayo kanye nenani lomkhiqizo elingama-yuan ayizigidi eziyizinkulungwane ezingu-1.8.
