API SPEC 15HR:2001 pdf download.Specification for High Pressure Fiberglass Line Pipe.
The manufacturer shall own or have access to gages and working gages.
c. The use of master gages in checking product threads should he minimized. Such use should he confined to cases of dispute which cannot he settled by rechecking the working gage against the reference master. Good care should be exercised when the master gage is assembled on a product thread.
5.4 REQUALIFICATION
5.4.1 Requalification Tests for Pipe and Prime Connection
Changes as described in Appendix A for previously qualified systems shall require the following minimum tests:
The long-term static LTHS shall be verified at 150°F, or higher temperature if so rated, after any changes as described in Appendix A by conducting the abridged ASTM D 2992 Procedure B (free-end) test as described in Section 12 of ASTM D2992. Test samples shall be assembled by the manufacturer’s documented make-up procedure.
Test samples shall be a size no smaller than 2 in. nominal diameter. The same outside diameter to reinforced wall ratio (Dli) constraints as in 5.1.1 shall apply for requalification.
5.4.2 Requalification Tests for Other Components
The requalification tests of 5.1.2, 5.1.3 and 5.1.4 shall
be repeated after any change as described in Appendix A.
6 Process of Manufacture and Material
6.1 PROCESS OF MANUFACTURE
Pipe furnished to this specification shall be produced by filament winding (FW) or centrifugal casting (CC) methods.
Components furnished to this specification shall be produced by compression molding (CM), centrifugal casting (CC), filament winding (FW) or resin transfer molding (RTM) methods.
6.2 MATERIALS
The reinftrced wall of pipe and components shall consist of thermosetting polymers reinforced with glass fibers.
Acceptable polymers may include epoxy resins, polyester resins and vinyl ester resins.
Note: Other resins and reinforcements shall be considered for inclusion in this standard when evidence is presented to show that they are suitable tbr the applications covered by this standard.
7 Quality Program
7.1 QUALITY MANUAL
The manufacturer shall maintain a quality manual. All prior revisions shall he retained for a period of not less than 5 years.
7.2 PROCESS CONTROL REQUIREMENTS
Manufacturer shall institute and maintain a process documentation program to assure communication of approved manufacturing procedures to qualified receiving, manufacturing and quality control personnel and their respective supervisory personnel to include the following functions:
a. Raw material acceptance.
h. Allowable mixing procedure(s).
c. Fabrication practice(s).
d. Cure procedure(s).
It shall he the responsibility of the manufacturing company to maintain copies of the document for a minimum of 5 years from the date the manufacturing of the product is discontinued.
7.3 QUALITY CONTROL EQUIPMENT
7.3.1 General
Equipment used to inspect, test or examine material or other equipment shall be identified, controlled, calibrated and adjusted at specified intervals in accordance with documented manufacturer instructions, and consistent with referenced industry standards to maintain the accuracy required by this specification.
7.3.2 Dimensional Measuring Equipment
Dimensional measuring equipment shall he controlled and calibrated by the manufacturer’s written specification.
7.3.3 Pressure Measuring Devices
a. Test pressure measuring devices shall he either pressure gages or pressure transducers and shall he accurate to 2.0% of full scale range or less.
b. The manufacturer shall own or have access to a dead weight testing device.
c. All pressure measuring devices shall be calibrated once every 6 months to maintain the required accuracy or callbrated when subjected to unusual or severe conditions, such as, would render its accuracy questionable.
7.4 QUALITY CONTROL TESTS.
