QTY. 1. WELKER ENGINEERING CO. SUGAR LAND TX. CONSTANT PRESSURE 1000 CC SAMPLE CYLINDER MAX. W.P 3600 PSI TESTED 6000 PSI 1000 CC D.O.T.-E 11054 CP2HP0091-M1136 3/02 CP2-GM 12/08 INLET FLANGE WTN 9901 OUTLET FLANGE WTN 10656 ALL STAINLESS STEEL. CYLINDER ONLY NO VALVES OR GAUGES. WITH D.O.T APPROVED CYLINDER CARRYING CASE MEETS OR EXCEEDS D.O.T REQUIREMENTS OF CFR TITLE 49. WELKER CONSTANT PRESSURE CYLINDER IS THE CONTAINER FOR THE SAFE COLLECTION AND TRANSPORT OF ACCURATE SAMPLES FOR LABORATORY ANALYSIS. PRE-CHARGING THE CONSTANT PRESSURE CYLINDER WITH AN INERT GAS OR PIPELINE GAS ALLOWS THE SAMPLE TO BE COLLECTED AT PIPELINE PRESSURE. NO PRESSURE DROP DURING SAMPLE COLLECTION PROTECTS AGAINST PHASE CHANGE AND ENSURES SAMPLE INTEGRITY. IN THE LABORATORY CONNECT A GAS SUPPLY WITH PRESSURE EQUAL TO PIPELINE PRESSURE TO THE PRE-CHARGE SIDE OF THE CYLINDER. AS THE SAMPLE IS INJECTED INTO THE ANALYZER FULL PRESSURE IS MAINTAINED IN THE CYLINDER
