Zinc Plated Soft Iron Ring Joint Gasket
In a natural environment, as we all know, materials like soft iron and carbon steel are often rusted. So how to solve this problem? The best method is to make soft iron or carbon steel with zinc plating. In the following articles, we will know more about zinc-plated gasket
Welcome to Know Zinc Plated Soft Iron Ring Joint Gasket
As soft iron is easy to rust in the natural environment, zinc plated soft ring joint gasket can solve this problem and last a longer time. Its max hardness is 90 HB. The color of the zinc plating can be white and colorful.
Why do we Use Zinc Plated Soft Iron Ring Joint Gasket?
We use zinc-plated soft iron ring joint gaskets because the cost of soft iron is significantly lower than that of other metals. Other materials like Monel 400 and Alloy 825 are expensive, but they are used when gaskets need contact for very critical service.
What grade Soft Iron used for Ring Joint Gasket?
The soft iron we use for making ring joint gasket is DT4
Application
Pipe flanges, tower tanks, and pressure vessels use the zinc-plated soft iron ring joint gasket. It is also suitable for high-speed joint surfaces, high-temperature, and high-pressure valves. And it can perfectly seal on wellheads and Christmas trees in the oil and gas industry.
