STEEL PIPE, USED IN THE ASSEMBLY OF SLEEVES SEAMLESS, OF CIRCULAR CROSS SECTION COLD DRAWN/COLD ROLLED, NON ALLOY STEEL. WITH AN EXTERNAL DIAMETER OF 7.13 INCHES (181 MM) LENGTH 21 INCHES (533 MM) WITH A CEV (CARBON EQUIVALENT VALUE) NOT EXCEEDING 0.85

SEAMLESS PIPE WORK MADE OF COLD ROLLED CARBON STEEL. CONNECTED TO OTHER PIPEWORK BY BUTT WELDING. THE PIPE WORK IS USED FOR CONNECTING THE VARIOUS PIECES OF WELL TEST EQUIPMENT TOGETHER ON THE RIG. THE PIPE WORK FOR VARIOUS TYPES OF END CONNECTIONS IS AVAILABLE. HAMMER UNION CONNECTED PIPE WORK IS MOST COMMONLY USED DUE TO THE EFFICIENT 'RIG-UP AND RIG-DOWN' TIME. ALL PIPE WORK IS PRESSURE AND TEMPERATURE RATED TO MEET HOSTILE ENVIRONMENTS. PRESSURE RATINGS FOR PIPE WORK ARE 10,000PSI OR 15,000PSI. THE EXTERNAL DIAMETERS 75mm; 100mm; 150mm (3 INCHES; 4 INCHES; 6 INCHES). CARBON EQUIVALENT VALUE (CEV) 0.36-0.40.

SEAMLESS PIPES MADE OF COLD ROLLED CARBON STEEL. CONNECTED TO OTHER PIPEWORK BY BUTT WELDING. THEY ARE USED AS ARE PART OF A WELL TEST PRODUCT LINE THEY ARE ATTACHED TO A PORT AND ARE DESIGNED TO ACCURATELY MEASURE AND RECORD THE PRESSURE AND TEMPERATURE OF FLUIDS PRODUCED BEFORE THE PASS THROUGH THE CHOKE MANIFOLD BY BOTH MANUAL & ELECTRONIC MEANS. DATA HEADERS HAVE 3 OR 4 PORTS WHERE DATA IS COLLATED. THE HEADERS ARE LINED PIPE WORK THAT IS FITTED WITH ½" NPT HALF COUPLINGS WITH A ¾" NPT HALF COUPLING USED TO TIE IN A TEMPERATURE PROBE. THE TEMPERATURE PROBE IS NOT PART OF THIS BTI, ONLY THE DATA HEADER DUE TO IT BEING MODIFIED PIPE WORK. THE EXTERNAL DIAMETERS 75mm; 100mm; 150mm (3 INCHES; 4 INCHES; 6 INCHES). CARBON EQUIVALENT VALUE (CEV) 0.36-0.40. THERE ARE NOT TESTING OR ELECTRICAL APPARATUS INCLUDED.
