Txhawm rau txhim kho tank fabrication efficiency thiab txo cov voj voog ncig, qhov project kuj xav taudav hlau daim hlautxhawm rau txo qis cov pob qij txha welding, uas yuav pab txo qis kev pheej hmoo ntawm SCC hauv kev pabcuam ammonia.
Tsim steel ntu qhwv thiab racked rau kev tiv thaiv, npaj rau 100,000 m³ ammonia cia tank sib dhos.
GNEE STEEL muab siab -precision steel phaj dov thiab lub tog raj kheej tsim cov kev daws teeb meem rau lub tank manufacturers thoob ntiaj teb.Xa peb koj cov phaj specifications los yog fabrication drawings rau ib tug ceev hais.
