Attention: Mr. T.J. Hayes, Jr.
P.O. Box 19415
Houston, Texas 77024
Gentlemen:
This is to acknowledge your inquiry of August 8, 1972, requesting our review of the test data,
and installation history of the ZAP-LOK method of joining pipe and whether it complies with
Section 192.273 of the U.S. Department of Transportation Pipeline Safety Standards.
Use of the ZAP-LOK method is provided for under the requirements listed in Subpart F - Joining
of Materials Other Than by Welding. Based on the data submitted with your letter of August 8,
including the description by various gas operators of their individual installations the ZAP-LOK
method of joining pipe appears to comply with the provisions of Section 192.273.
Sincerely,
\signed\
Joseph C. Caldwell
Director
Office of Pipeline Safety
