DON’T MISS THIS IFPE FEATURE PRESENTATION: New White Paper on Pressure Ratings and Design Guidelines for Continuous Cast Ductile Iron in Hydraulic Applications

Announcing the release of the white paper on the MSOE (Milwaukee School of Engineering) Study titled “Pressure Ratings and Design Guidelines for Continuous Cast Ductile Iron in Hydraulic Applications”.

This paper has been submitted by Bob O’Rourke, Met. Eng. - Product Engineering Manager of Dura-Bar and Gordon Weiler - National Sales Manager of Daman Products Company, Inc.

On March 4-8, 2014, this collaboration with Dura-Bar, Daman Products and MSOE will be featured at the IFPE 2014 Conference in Las Vegas, Nevada.  On March 7th, O’Rourke and Weiler will co-present the highlights discovered during this study.

WHITE PAPER ABSTRACT:

The methods for determining pressure ratings in components within a hydraulic circuit are defined by NFPA standard T2.6.1, R1-1991. This standard requires 2 separate tests: A burst test to determine the ultimate allowable stress and an impulse test to validate the fatigue strength of a component under cyclical loading.

In this study, the pressure rating for continuously cast ductile iron bar stock was determined using the guidelines established in T2.6.1 utilizing test manifold blocks consisting of two drilled ports, one under hydraulic pressure and the other open to the
atmosphere.

This report contains the results of the pressure rating validation and plotting of the fatigue data for 1045 plain carbon hot rolled steel and ASTM A536 grade 65-45-12  continuous cast ductile iron.
