Ukuba ngumhlinzeki/umhlinzeki wezinsizakalo zokuhweba zamazwe ngamazwe ophelele kakhulu embonini yensimbi.
Unyaka ka-1998
I-Tianjin Hengxing Metallurgical Machinery Manufacturing Co., Ltd.
Le nkampani yasungulwa ngo-1998, inkampani yaqasha onjiniyela abayi-12 abangochwepheshe kuzo zonke izici, abasebenzi abangaphezu kuka-200, izinhlobo ezahlukene zemishini yokugaya emikhulu, ephakathi nencane engaphezu kwe-100. Sigxile ekukhiqizeni izinhlobo zomugqa wokukhiqiza wamapayipi ensimbi namakhoyili ensimbi, umugqa wokukhiqiza we-galvanizing, kanye nazo zonke izinhlobo zezingxenye zensimbi zomshini. Sisekelwe emandleni ayo, besilokhu sithuthuka njalo.
Unyaka ka-2004
I-Tianjin Yuxing Steel Tube Co., Ltd.
Kusukela ngo-2004, singakhiqiza ipayipi lensimbi i-LSAW (usayizi kusukela ku-310mm kuya ku-1420mm) kanye nabo bonke osayizi besikwele nesiyindilinga (usayizi kusukela ku-20mm * 20mm kuya ku-1000mm * 1000mm), ngomkhiqizo waminyaka yonke wamathani angu-150,000. Uhlobo lomkhiqizo luhlanganisa ipayipi eligobile elibandayo, insimbi egoqwe eshisayo, ipayipi eliyisikwele, ipayipi elibunjiwe, izinkokhelo ze-C ezivulekile njll. Ngemikhiqizo yalo yokunemba okuphezulu nokuhlukahluka, iwine udumo lwamakhasimende olusakazeke kabanzi ekhaya nakwamanye amazwe. Sidlulile isitifiketi sesistimu yokuphatha ikhwalithi ye-ISO9001:2000, isitifiketi se-ABS esigunyazwe yi-United States classification society, isitifiketi se-API, futhi saqamba nesihloko se-Tianjin Science and Technology Small and Medium-size Enterprises.
Unyaka ka-2008
Iminyaka eyi-10 yesipiliyoni sokuthumela ngaphandle. Ububanzi bebhizinisi ezimakethe zasekhaya nezamazwe ngamazwe, imikhiqizo ithunyelwa e-United States, eBrazil, eNingizimu Korea, eThailand, ePhilippines, eVietnam nakwamanye amazwe.
Unyaka ka-2011
Ukuthumela ngaphandle ipayipi lensimbi kanye nepayipi le-GI (eliyindilinga/eliyisikwele/eliyisikwele/eliyindilinga/eliyindilinga/eliyindilinga/eliyindilinga/eliyindilinga/eliyi-LTZ) kanye ne-CRC kanye ne-HRC kanye nepayipi lokufaka kanye nezintambo kanye nensimbi engagqwali kanye ne-scaffolding kanye ne-GI PPGI kanye namaphrofayili kanye nebha yensimbi kanye nepuleti lensimbi kanye nepayipi elihlanganisiwe kanye nepayipi lokufaka kanye nepayipi le-LSAW SSAW njll.
Izinga lemikhiqizo lifaka phakathi i-BS1387, i-ASTM A53, i-DIN-2440 2444, i-ISO65, i-EN10219, i-ASTM A 500, i-API 5L, i-en39, i-BS1139 njalo njalo. Ithole isihloko esithi "umkhiqizo okhethwayo embonini".
Unyaka ka-2016
I-Ehong International Trade Co., Ltd.
Phakathi nalesi sikhathi, sihlanganyele emibukisweni eminingi yokuhweba kwamanye amazwe kulo lonke elaseShayina, futhi sazana namakhasimende amaningi abambisene isikhathi eside.
Sinelabhorethri yethu engenza ukuhlolwa okulandelayo: Ukuhlolwa kwengcindezi ye-Hydrostatic, Ukuhlolwa kokwakheka kwamakhemikhali, Ukuhlolwa kobulukhuni be-Digital Rockwell, Ukuhlolwa kokutholwa kwamaphutha e-X-ray, Ukuhlolwa komthelela we-Charpy.
Unyaka ka-2022
Kuze kube manje, sineminyaka engu-17 yesipiliyoni sokuthumela ngaphandle futhi sibhalise uphawu lokuhweba lwe-Ehong.
Imikhiqizo yethu eyinhloko izinhlobo zepayipi lensimbi (ERW/SSAW/LSAW/Seamless), insimbi yokhuni (H BEAM/U beam njll), insimbi yokhuni (Angle bar/Flat bar/Deformed rebar njll), CRC & HRC, GI,GL & PPGI, ishidi kanye nekhoyili, i-Scaffolding, insimbi yocingo, i-wire mesh njll.
