Alloy Slip-on Flanges with a low height

　　Alloy Slip-on Flanges with a low height, the flange stiffness, load capacity has increased. Compared with the welding flange, welding workload, welding consumes high, can not withstand high temperature and pressure and repeated bending and temperature fluctuations, but the site installation is more convenient and popular can be omitted welding seam rubbing injury process.
