Giles\nMarket Manager\nRobroy Industries\nRiver Road\nVerona, PA 15147\nDear Mr. Giles:\nWe have reviewed the request in your letter of January 22, 1974, for an interpretation as to\nwhether the coated flexible steel casing described in your letter requires cathodic protection.\nWe find that no cathodic protection is required for this protective flexible steel casing because the\ncasing is not considered part of a pipeline as that term is defined in Section 192.3 of the Federal\nsafety standards. However, the mechanical connection between the plastic service pipe and steel\nfitting just above the ground level must comply with Section 192.281(e) of the Federal standards.\nThank you for your interest. We trust this answers your question satisfactorily.\nSincerely,\n/signed/\nJoseph C.

Caldwell\nDirector\nOffice of Pipeline Safety\n400 Sixth Street SW\nRoom 107\nWashington, D. C. 20590\nDear Mr. Caldwell:\nEnclosed is information on the ROBROY RIZER-FLEX as manufactured by ROBROY\nINDUSTRIES. We are requesting an interpretation of this product meeting the OPS regulations\nas set forth in Part 192 Minimum Federal Safety Standards.\nRIZER-FLEX is a PVC plastic coated flexible steel casing that incorporates a\ncompression service adapter to make the transition at ground level from the plastic service line to\nthe conventional outside meter setting. RIZER-FLEX is designed to give protection to the plastic\nservice line brought to the ground level. The riser eliminates the need for cathodic protection and\nthe use of an underground fitting near the foundation wall. The flexible steel casing permits\ngradual bending of the plastic service pipe during installation and also compensates for ground\nmovement caused by settling or \"heaving\".\nThe casing or conduit approach to protecting the plastic service line is similar to that taken\nby others. It is our understanding that you have recently reviewed and acknowledged this\nconcept. We look forward to receiving your interpretation.\nVery truly yours,\nROBROY INDUSTRIES\nDAL\\192\\3\\74-02-02\n2\n\n<<<PAGE 3>>>\n\nDAL\\192\\3\\74-02-02\nGAS PRODUCTS/COATINGS DIVISION\nThomas G.
