API SPEC 15HR
Specification for High Pressure Fiberglass Line Pipe
|Publication Date:||1 August 2001|
This specification was formulated to provide for the availability of safe, dimensionally and functionally interchangeable high pressure fiberglass line pipe with a Specification 15HR Standard Pressure Rating from 500 lbf/in2 to 5000 lbf/in2, inclusive, in 250 lbf/in2 increments. This specification is limited to mechanical connections.
Technical content provides requirements for performance, design, materials, tests and inspection, marking, handling, storing and shipping.
Critical components are items of equipment having requirements specified in this document.
This specification covers fiberglass pipe utilized for the production of oil and gas. Specific equipment covered by this specification is listed as follows:
High pressure line pipe and couplings.
Reducers and adapters.
1.2.2 Service Conditions
The standard service conditions for Specification 15HR Standard Pressure Rating are as follows:
Service life is 20 years.
Service temperature is 150°F.
The fluid environment is salt water.
Axial loads shall include end loads due to pressure and bending, where the radius of curvature of the pipe divided by the outside radius of the pipe shall be greater than or equal to 1200.
Cyclic pressure variation shall include 3,000 cycles from O to 120% of Specification 15HR Standard Pressure Rating. Cyclic pressure variation shall include 109 cycles with an R value of 0.9.
(R = minimum pressure divided by maximum pressure).
Service conditions other than the standard Specification 15HR conditions are discussed in 5.1.1 and Appendix G.
A decimal/inch system is the standard for the dimensions shown in this specification. Nominal sizes will continue to be shown as fractions. For the purposes of this specification, the fractions and their decimal equivalents are equal and interchangeable. Metric conversions are described in Appendix B.
AVAILABILITY OF TEST RESULTS
The manufacturer shall prepare a report as outlined below:
This report shall be kept on file with the manufacturer and a copy shall be available on request to each purchaser. Any variance from the above test procedures voids the test as having been conducted according to API Specification 15HR. Any user company may witness representative testing of pipe and connections, observe manufacturer's testing procedures, or inspect test apparatus.
Prior to presenting results of tests in verbal or written reports, articles, or advertisements and stating that the tests were made in accordance with API Specification 15HR the manufacturer shall complete the report described above. This copy must be dated and reported test results certified by a management official of the company. It shall be the responsibility of the manufacturing company to maintain copies of the certified tests results for a minimum of 5 years from the date the manufacturing of the product is discontinued.
When the results of the tests are presented in verbal or written reports, articles, or advertisements and state that the tests were made in accordance with API Specification 15HR; such reports, articles, or advertisements must be worded in a fashion which will not imply that the American Petroleum Institute either recommends or disapproves use of the subject components.
