Chitoliro cha Chitsulo cha Astm A139 Chokhazikika

Chithunzi Chodziwika cha Astm A139 Steel Pipe Standard

Kufotokozera Kwachidule:

Kaya mukufuna chitoliro chomangira, mafuta ndi gasi, kapena ntchito zina zamafakitale, chitoliro chathu cha S235 J0 chapangidwa kuti chikwaniritse miyezo yokhwima ya chitoliro chachitsulo cha ASTM A139 kuti chitsimikizire kudalirika ndi magwiridwe antchito ngakhale m'malo ovuta kwambiri.

Tikuyambitsa chitoliro chachitsulo chozungulira cha S235 J0 - yankho losiyanasiyana lopangidwa kuti likwaniritse zosowa zosiyanasiyana zamafakitale amakono. Kampani yathu yopangidwa mu fakitale yapamwamba yomwe ili ku Cangzhou City, Hebei Province, yakhala ikutsogolera pakupanga zitsulo kuyambira 1993. Kampaniyo ili ndi malo okwana masikweya mita 350,000 ndipo ili ndi chuma chonse cha RMB 680 miliyoni. Tikunyadira kukhala ndi antchito odzipereka aluso 680 odzipereka popereka zinthu zapamwamba.

Chimodzi mwa zinthu zabwino kwambiri za chitoliro chachitsulo chozungulira cha S235 J0 ndi kusinthasintha kwake kodabwitsa kwa kukula kwake m'mimba mwake ndi makulidwe a khoma. Kusinthasintha kumeneku kumatithandiza kukwaniritsa zofunikira zosiyanasiyana zopangira, makamaka popanga mapaipi okhala ndi makoma olimba apamwamba. Kaya mukufuna chitoliro chomangira, mafuta ndi gasi, kapena ntchito zina zamafakitale, chitoliro chathu cha S235 J0 chapangidwa kuti chikwaniritse zofunikira kwambiri.ASTM A139miyezo ya chitoliro chachitsulo kuti zitsimikizire kudalirika ndi magwiridwe antchito ngakhale m'malo ovuta kwambiri.

Kudzipereka kwathu ku khalidwe ndi kupanga zinthu zatsopano kumatanthauza kuti chidutswa chilichonse cha chitoliro chachitsulo cha S235 J0 chimayesedwa mwamphamvu komanso kuwongolera khalidwe, kuonetsetsa kuti chinthu chomwe mumalandira sichikukwaniritsa komanso chimaposa miyezo yamakampani. Ndi chidziwitso chathu chachikulu komanso ukadaulo, tadzipereka kupatsa makasitomala athu mayankho abwino kwambiri ogwirizana ndi zosowa zawo.

Ubwino wa Zamalonda

1. Chimodzi mwa ubwino waukulu wa chitoliro chachitsulo cha ASTM A139 ndi kusinthasintha kwake m'mimba mwake ndi makulidwe a khoma. Kusinthasintha kumeneku kumalola opanga kupanga mapaipi amitundu yosiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana za polojekiti.

2. Mphamvu zopangira za kampani ngati yathu, yomwe ili ku Cangzhou, Hebei Province, zimawonjezera ubwino wa ASTM A139.

3. Yokhazikitsidwa mu 1993, fakitale yathu ili ndi malo okwana masikweya mita 350,000, ili ndi katundu wokwana RMB 680 miliyoni, ndipo imagwiritsa ntchito antchito aluso 680. Zomangamanga zazikuluzi zimatithandiza kukwaniritsa zosowa zosiyanasiyana za makasitomala pamene tikupitirizabe kupanga zinthu zapamwamba.

Kulephera kwa malonda

1. Muyezo wa ASTM A139 sungakwaniritse zofunikira zonse za ntchito zina, zomwe zimapangitsa kuti magwiridwe antchito azikhala ochepa pamikhalidwe yovuta kwambiri.

2. Njira yopangira zinthu ingakhale yovuta komanso yokwera mtengo kuposa miyezo ina, zomwe zingakhudze mitengo ndi kupezeka kwake.

Pamene tikupitiriza kupanga zatsopano ndikukulitsa luso lathu, tikudziperekabe kupereka mayankho apamwamba achitsulo omwe akwaniritsa zosowa zosintha zamakampani.

FAQ

Q1: Kodi ASTM A139 ndi chiyani?

ASTM A139 ndi muyezo womwe umafotokoza zofunikira pa chitoliro chachitsulo cholumikizidwa ndi magetsi. Mapaipi awa nthawi zambiri amagwiritsidwa ntchito pogwiritsa ntchito mphamvu zochepa ndipo amadziwika kuti ndi olimba komanso okhazikika. Muyezowu umaonetsetsa kuti mapaipiwa akukwaniritsa mawonekedwe ake amakina komanso kapangidwe ka mankhwala, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'mafakitale osiyanasiyana.

Q2: Kodi ubwino wa chitoliro chachitsulo chozungulira cha S235 J0 ndi wotani?

Chimodzi mwa zabwino zazikulu za chitoliro chachitsulo cha S235 J0 ndi kusinthasintha kwake m'mimba mwake ndi makulidwe a khoma. Kusinthasintha kumeneku kumalola opanga kupanga chitoliro chapamwamba komanso chokhuthala chomwe chingapirire kupsinjika kwakukulu ndi kupsinjika. Kutha kusintha izi kumapangitsa chitoliro cha S235 J0 kukhala chisankho chabwino kwambiri pamapulojekiti omwe amafunikira kukula ndi mphamvu zinazake.
