Standard Specification for Centrifugally Cast Dual Metal (Gray and White Cast Iron) Cylinders
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers centrifugally cast cylinders with an outer layer of white cast iron and the remainder of the material of gray cast iron. These castings are suitable for pressure containing parts of the design strength of which is based on the gray iron portion of the cylinder. The white iron portion of the cylinder shall be made to a minimum hardness and the casting process shall be controlled to produce a metallurgical bond between the two metal layers. All surfaces shall be machined prior to the cylinders being placed into service. The tensile strength of the cast irons shall be measured by tension testing while the thickness of the white cast iron shall be determined by ultrasonic testing.
Scope
1.1 This specification covers centrifugally cast cylinders with an outer layer of white cast iron and the remainder of the material of gray cast iron. These castings are suitable for pressure containing parts the design strength of which is based on the gray iron portion of the cylinder. These castings are suitable for service at temperatures up to 450F [230C].
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.
1.3 The following safety hazards caveat pertains only to the test method portion, Section 8, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
