印度尼西亚采购需求：玉米面粉厂、小麦面粉厂、面粉混合项目、面粉加工、谷物清理、种子清理

I'm looking for a reliable supplier for spouting pipes specifically designed for grain and flour products. We need options in both mild steel and stainless steel to accommodate different application requirements. Could you provide details on your product range, including specifications, available sizes, and pricing? Additionally, if you have any recommendations based on industry standards or best practices, it would be greatly appreciated. Thanks!
