•According to different polymer and production line speed requirements to provide different structure calibration and water ring structure
•The material is high quality wear-resistant copper, which can improve the working life of calibration
•Vacuum groove structure can be used in the calibration area, which has large cooling area and good effect
•The inner hole surface can be specially treated with chromium plating Coating, which has high wear resistance and smoothness, and can effectively improve the internal and external quality of pipe product.
