Product Description123
The neck height is higher, which improves the stiffness and bearing capacity of the flanges. Compared with butt-welding flanges, the welding workload is large, the consumption of welding rod is high, and it can't withstand high temperature and high pressure as well as repeated bending and temperature fluctuation, but the on-site installation is more convenient, and the welding seam can be omitted from the process of patting and kneading.
