The Public Utility Industry has been promoting the application of matiufiotured and natural gases to Industrisl heating processes ever since the early years of World War I. The uso of gaaeoua fuels for such purposes has ex* paodod at an ever Increasing rate, so that in 1952 gas sales to industries in the United States amonted .to 28ft billions of therms (100,000 Bio), rep resenting over one-hall of all gat utility sales and approximately ono-founb of the gas utilities total revenues. Despite the great Increases fn the ttse of ges in Industry throughout these many years, there remained a great need for practical rules or regulations--"code" if your please--to govern the installa tion of gas piping or gas utilising equip ment to promote safety and user satis faction in industrial plants. It was accordingly decided only about a year and a half ago. In April 1952, that one of the newer committees In the lads* trial and Commercial Section of the American Gas Association--namely, the Industrial Css Practices Committee-- should assume the task of preparing a detailed outline covering standard r* quirementi for Industrial consumer* gas piping systems. Furthermore, It I* the hope of the Section that this Coo* mStiee's work in this regard might even tually serve ns a basis for a new Ameri can Standard covering gas piping hi industrial plants in partichr as well all consumer-owned ges piping cnrrytoll pressures in excess of one-ball pound per square inch gauge.

AT LOWER COST WITH FAMOUS OUO-STEP LEVERA6E IS NOW AVAILABLE FOB THE FUST TIME ON THESE SMALLER SITED STEAM TRAPS. GET HIGHEST DRAINAGE CAPACITY -AT. LOWEST COST. Duo*5tep is the revolutionary double fulcrum principle that affords maximum leverage to "crack" the valve from the orlfibe seat, teamed with "Follow-through" power that opens the Orifice completely. This double action actually gives you double the draioage capacity of ordinary steam traps. MOISEI 60-D traps ore of cast semi-steel construction, designed for pressures up to 200 P.
