OEM China ASTM A106 / API 5L / ASTM A53 ibakala b umbhobho intsimbi engenamthungo oyile kunye negesi umbhobho
Isishwankathelo
Sisoloko siwenza umsebenzi wenziwe ngokuba liqela lobuchwephesha ukuze siqiniseke ukuba sinokukunika owona mgangatho uphezulu kakhulu kunye nelona zinga lisebenzayo. Kwi-ASTM A106 / API 5L / ASTM A53 yebakala B umbhobho wentsimbi ongenamthungo weoli kunye nombhobho wegesi, sinamava angaphezu kweshumi leminyaka eli-3 lokuyinikezela kwiimeko ezahlukeneyo zesicelo. Siza kuthabatha ukwaneliseka kwabathengi njengowona mgangatho uphezulu, sisebenzise ubutyebi bethu ukubonelela ngeyona nto ifunwa ngumxhasi wethu kwaye okona kulungileyo kumthengi wethu.
Samkela ngokufudumeleyo abathengi basekhaya nabaphesheya ukuba bandwendwele inkampani yethu kwaye babe neentetho zeshishini. Inkampani yethu ihlala igxininisa kumgaqo "womgangatho omhle, ixabiso elifanelekileyo, inkonzo yeklasi yokuqala". Sizimisele ukwakha intsebenziswano yexesha elide, enobuhlobo kunye neyokuncedana nawe.
Isicelo
Umbhobho wensimbi ongenamthungo wokusebenza okuphezulu kwe-ASTM A106, ilungele ukushisa okuphezulu

Imfuneko yoVavanyo
Ukongeza ekuqinisekiseni ukubunjwa kweekhemikhali kunye neempawu zemishini, iimvavanyo ze-hydrostatic zenziwa nganye nganye, kwaye iimvavanyo ze-flaring kunye ne-flattening ziyenziwa. . Ukongezelela, kukho iimfuno ezithile ze-microstructure, ubukhulu bengqolowa, kunye ne-decarburization layer yombhobho wensimbi ogqityiweyo.
