Class 75 Carbon Steel Tube Angle Ring Flanges
This line of carbon steel Marzolf flanges is designed to fit OD tube angle face rings. They are thicker than our class 75 rings. The Marzolf two-piece design allows you to simply remove the broken rings and replace them without cutting and rewelding the pipe. The interleaving component is engineered to provide uniform preload to assure a consistent and effective seal. Our carbon steel rings are available with electro-zinc plate or E-coat epoxy coating to enhance corrosion resistance.
Marzolf flanges save you money by expediting the repair to reduce downtime.
