Forging, heat treatment, machining, welding, cleaning and testing under one roof in Cangzhou — China’s pipe-fitting capital — run on a digital MES that tracks every part by heat number.锻造、热处理、机加工、焊接、清洗与检测，全部集中在中国管件之都沧州的同一基地，由数字化 MES 按炉批号追踪每一个零件。
Six workshops. Zero hand-offs.六大车间，零外包环节。
Keeping every critical process in-house is how we guarantee schedule, metallurgy and accountability.所有关键工序自主完成，是我们保障交期、冶金质量与责任到底的方式。
