benefits of using mondi sulfuric acid piping

Features & Benefits Of Using Mondi™

Features:

Mondi is a special alloy of ductile iron with unique metallurgy that was developed to handle 92-99% sulfuric acid at temperatures of up to 300° F (149° C).

Mondi piping systems offer unique improvements in:

Metallurgy
Heavy wall thickness
Fitting design
Flange face finish
Step Ring Fawn Gylon^TM gaskets

These features result in superior piping systems that will provide 20 plus years of excellent services:

Superior ductility eliminates the catastrophic failure and breakage that can occur with brittle gray cast iron.
Pipe and fittings have durable heavy wall construction.
Most patterns for fittings have been improved to eliminate chaplets.
Special flange face finish has serrated spiral grooves with a pointed profile that bites into the gasket for a tight seal.
APT's special step gasket is made of Fawn Gylon. It provides an excellent seal in the critical sealing are at the pipe inside diameter.

Benefits:

Proven Technology

Mondi has been the industry standard for reliable performance in sulfuric acid plants since 1983. APT has supplied over 700 Mondi systems in North America, South America, Australia, Africa, and Asia since 1991.

Long Operating Life

Reduced maintenance with a service life up to four times the life of standard metallurgy ductile iron.

Operating Safety

Excellent ductility and durable construction provides safe, trouble-free operation.

Environmental

Special flange face finish and step ring gasket provides a tight leak-free seal at the pipe I.D. These Fawn Gylon step ring gaskets have excellent recovery to thermal cycling over years of operation and excellent resistance to hot concentrated acid.

Resistance to Concentration Changes

A tough sulfate film provides corrosion resistance when weaker acid is formed due to process upset or shutdown conditions.

Cost-Effective and Easy to Retrofit
