Overview

Zvese zvatinoita zvinowanzobatanidzwa nedzidziso yedu "Shopper kutanga, Vimba nekutanga, kuzvipira kurongedza chikafu uye kuchengetedzwa kwezvakatipoteredza kune High Quality Seamless uye Welded Steel Pipe, Isu tinoisa chokwadi uye hutano semutoro wekutanga. Iye zvino tava nenyanzvi. Vatengesi vepasi rese vakapedza kudzidza kubva kuAmerica. nezvigadzirwa zvinodhura zvakanyanya uye zvine hungwaru mushure mekutengesa-sevhisi Tinotenda zvakasimba kuti: isu takatanhamara sezvatiri nyanzvi.

Pakati pezvakajairwa simbi isina musono pombi zvinhu, DIN1629 ST52 ndechimwe chezvinhu zvinonyanya kushandiswa. MuChinese zviyero, inowanzoenderana neGB/T8162 Q345B. Izvo zviviri zvinogona kutsiviwa kune mumwe nemumwe, asi hazvienderane zvizere. .
