Product Description

The MERSEN S3-02-30 is a graphite rupture disc with a 30 psig burst pressure, designed for 2-inch compatible pipe size and featuring a 3 9/10-inch overall diameter. This MERSEN product provides overpressure protection in industrial systems.

Frequently Asked Questions

What is the MERSEN S3-02-30 rupture disc used for?

The MERSEN S3-02-30 graphite rupture disc provides overpressure protection in industrial piping systems. It is designed to burst at a set pressure of 30 psig, safeguarding equipment and personnel from excessive pressure buildup in applications such as chemical processing, oil and gas, and pharmaceutical manufacturing.

What are the specifications of the MERSEN S3-02-30 rupture disc?

The MERSEN S3-02-30 has a burst pressure of 30 psig, a compatible pipe size of 2 inches, and an overall diameter of 3 9/10 inches. Its body is made of graphite, and the manufacturer part number is S3-02-30. This disc is designed for overpressure relief in industrial systems.

Where to buy the MERSEN S3-02-30 rupture disc worldwide?

You can source the MERSEN S3-02-30 rupture disc through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.
