(Archived) Amko Receives High Pressure Cylinder Retesting Exemption

DANBURY, Conn., March 4, 2003 — AMKO Service Company, a wholly-owned subsidiary of Praxair, Inc., (NYSE:PX) announced today that it has recently been reissued a high-pressure cylinder retesting exemption (DOT E 11099) for their Gnadenhutten, Ohio and Adelanto, California facilities.


The exemption allows AMKO to retest 9-5/8" OD (outside diameter) high-pressure cylinders using acoustic emissions in lieu of hydrostatic testing. The modified exemption helps prevent unnecessary, costly repairs such as new manifold, bulkhead, and cabinet assembly replacements and/or possible chassis modifications.

In addition to acoustic emission retesting, services include: cryogenic tank and trailer vacuum investigations; specialized tank, pump and trailer repairs and painting; and custom equipment fabrication.  More information is available by visiting and or by calling 1-877-USE-AMKO.
