Standard: ASTM D2992

This practice is useful for establishing the hoop stress or internal astm d2992 versus time-to-failure relationships, under selected internal and external environments which simulate actual anticipated product end-use astm d2992, from which a design basis for specific piping products and materials can be obtained. Changes in materials or manufacturing processes will necessitate a reevaluation as described in Section Asrm design basis should be determined for each specific piping product.

Results obtained at one set of environmental conditions should atsm astm d2992 used for other conditions, except that higher temperature data can be used for design basis assignment for lower application temperatures. Pressure ratings for astn of various dimensions at each temperature may be astm d2992 using the HDS determined by testing one size of piping provided that the same specific process and material are used both for test specimens and the piping in question.

The design basis shall be determined for each specific piping product. It is the responsibility of the user of this standard to establish appropriate safety, health, astm d2992 environmental practices astm d2992 determine the applicability of regulatory limitations prior r2992 use.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This astm d2992 is valid for a given pipe or fitting only so long as the specimens astm d2992 truly representative of that material and manufacturing process.

Pressure ratings at each temperature for components other than straight hollow shapes may be calculated using the HDP determined by testing one size of piping provided that 1 the specific materials and manufacturing process used for the test astm d2992 are used for the components, 2 astm d2992 joints, the joining materials and procedures used to prepare the test specimens are used for field joining, and 3 scaling of critical dimensions is related to diameter and pressure rating of the component.

The values in parentheses are given for information purposes only. Therefore, the confidence limits should be astm d2992. Note 3-There is no known ISO equivalent to this standard. The values in parentheses are given for information purposes only. There is no known ISO equivalent astm d2992 this standard.

This practice defines an HDB for material in straight, hollow cylindrical shapes where hoop stress can astm d2992 easily calculated, and a PDB for fittings and joints where stresses are more complex.

This practice is useful for establishing the hoop stress or internal pressure versus time-to-failure relationships, under selected internal and external environments which simulate actual anticipated product end-use conditions, from which a design basis astm d2992 specific piping products and materials The strain basis HDB is most often used for buried pipe designs with astm d2992 pressures ranging from 0 to psig 1.

Therefore, the confidence limits shall be established. It is the responsibility of the user of this standard to establish appropriate safety and health practices and astm d2992 the applicability of regulatory limitations prior to use.

Because of the nature of the test and specimens employed, no single line can adequately represent the data. An alternative design practice based on astm d2992 strain versus time-to-failure relationships employs a strain astm d2992 HDB instead of the stress basis HDB defined by this practice. Because of the nature of the test and specimens employed, no single line can adequately represent the data. Top Categories Terms of Use.

Note 8-Scaling of astm d2992 and joints should be further verified by short-time testing in accordance with Test Method D Design and processing can significantly affect the long-term performance of piping products, and therefore should be taken into consideration during any evaluation. Work Item s – proposed astm d2992 of this standard. For example, if HDS is psi 34 kPathe pipe is limited to about psig kPa internal pressure, regardless of diameter.

This practice examines the inside and outside surfaces of the pipe near the squeeze to determine astm d2992 The strain basis HDB is most often used for buried pipe designs with internal pressures ranging from astm d2992 to psig 1. This practice defines an HDB astm d2992 material in straight, hollow cylindrical shapes where hoop stress can be easily calculated, and a PDB for fittings and joints where stresses are more complex.

Design and processing can significantly affect the long-term performance of piping products, and therefore shall be taken into consideration during any evaluation.

To astm d2992 fiberglass piping products, it is necessary to establish the stress versus cycles or time to astm d2992, or pressure versus cycles or time to failure relationships over three or more logarithmic decades of time cycles or hours within controlled environmental parameters.
