P.O. Box 32096 Decatur, GA 30032 Dear Mr. Ernst: In your recent letter received November 10, 1975, you ask if it is necessary that the reinforced epoxy resin pipe used in the Dresser Manufacturing Style 390 Meter Riser comply with all pertinent requirements of the Federal safety standards, such as Sections 192.59, 192.121, 192.123, 192.513, and Appendix B-1-ASTM D2517. The Office of Pipeline Safety Operations does not endorse or certify proprietary items. As a segment of a pipeline under the definition in Section 192.3, the epoxy resin pipe must comply with the requirements mentioned above and any other appropriate requirements of Part 192. Where a material specification is referenced by Part 192, it should be noted that only those editions listed in Appendix A or B are acceptable. Later published editions are not acceptable until they are approved and added to the appendices where appropriate. Thank you for your interest in pipeline safety. Sincerely, Cesar DeLeon Acting Director Office of Pipeline Safety Operations dal\192\121\75-12-02 1 <<>> Luke Ernst and Associates, Inc.

We are requesting an interpretation of this product meeting regulations set forth in Part 192 Minimum Federal Safety Standards. The Style 390 Meter Riser is purported to meet all requirements of the Regulation as stated in the enclosed literature - Form No. 575-1. The literature states further that the Style 390 provides a gas carrier of fiberglass reinforced epoxy pipe and that the carrier may be used at temperatures up to 150° F as specified in the codes. The question - is it necessary that the reinforced epoxy, as an integral part of the product, comply with all pertinent requirements of the Federal Safety Standard such as: Part 192.59 Part 192.121 Part 192.123(d) Part 192.513 Appendix BI ASTM D2517 We look forward to your interpretation.
