NEW CASE STUDY!
1600 Graphite Valve Packing have solved this challenge for our customers in Korea!
Let’s take a look at how it works
A chemical plant in Korea, which processes sulfuric acid gas using local packaging, had excessive stem corrosion due to severe leaks and applied furmanite as an emergency repair. Products featured in this case study is Chesterton® 1600 Graphite Valve Packing
Equipment: Control Valve
Temperature: 200C
Pressure: 40kg/cm2
Size: 50mm(I.D.) x 63mm(O.D.)
Superior Leakage Control
This graphite valve packing features advanced construction for superior leakage control and high integrity:
- Layers of graphite tape are plied into compact strands
- Each strand is reinforced with an Iconel® wire mesh covering
- Strands are square plait braided to form a dense pliable packing and further enhanced with blocking agents
- The packing’s exterior is densely coated with lubricating agents to reduce stem friction
- A passive corrosion inhibitor is applied to prevent valve stem pitting
Iconel® is a registered trademark of Special Metals Corporation.
